Professional Experience
Security Engineer
Warsaw Technology Company, Warsaw, Poland
Jan 2019 – Present
- Build defence into the system rather than bolting it on, so an attacker has far fewer ways in.
- Closed major vulnerabilities across the estate and built security automation that caught problems before they shipped.
- Harden cloud infrastructure and applications, removing the misconfigurations and weaknesses that attackers love to exploit.
- Secure the CI/CD pipeline, building checks into the build so insecure code is caught before it ever reaches production.
- Build detection and response tooling, giving the team the visibility and automation to react fast to real threats.
- Run assessments and advise engineering teams, helping developers build secure systems from the start.
Security Engineer / DevSecOps
Poland Software Group, Warsaw, Poland
Jul 2016 – Dec 2018
- Secured systems and pipelines and ran assessments for engineering teams, building security-engineering experience over years.
- Hardened systems and automated checks, steadily building the offensive and defensive skills the role demands.
- Learned hardening, secure pipelines and assessment on the job across more than two years.
- Gained the certifications and experience that led into a full security-engineer role of my own.
Education
MSc in Computer Security, Computer Security
Warsaw University of Technology
Sep 2011 – Jun 2016
- Master's in computer security covering cryptography, networks, secure systems and application security, with a project. The programme built the technical foundation engineering secure systems requires. It led directly into security engineering.
OSCP & Cloud Security Certification, Security Engineering
Offensive Security
Jan 2017 – Jun 2017
- Hands-on offensive-security and cloud-security certifications to recognised standards. They sharpened both the attacker and defender mindsets. They supported finding and engineering out real weaknesses in systems and infrastructure.
Certifications
OSCP & Cloud Security Certification
Offensive Security
Jun 2017 – Present
- Hands-on offensive-security and cloud-security certifications to recognised standards, which sharpened both the attacker and defender mindsets and support finding and engineering out real weaknesses in systems and infrastructure.
Recognition
A trusted security partner
- Relied on by engineering teams to make their systems genuinely secure, valued for closing real vulnerabilities and for building security into the pipeline so problems are caught before they ever ship.
Highlights
Closed major vulnerabilities
- Found and closed major vulnerabilities across the estate. Each serious weakness removed is a door shut on an attacker, so systematically closing them measurably shrinks how exposed the whole company is.
Caught problems before they shipped
- Built security automation that caught problems before they reached production. Stopping insecure code at the pipeline is far cheaper and safer than finding it after release, so shifting security left protects every deploy.

Key Takeaways for a Security Engineer Resume
Security engineering screens are technical and specific. These are what a hiring manager checks first:
- Show that you build. Tooling written, pipelines gated, infrastructure hardened as code, not just findings reported to someone else.
- Name your cloud platform and depth, since AWS, Azure and GCP security models differ enough that employers hire against one.
- Quantify what you removed, meaning vulnerability classes eliminated and attack surface closed, rather than tickets raised.
- Separate yourself from the analyst role explicitly, because engineer and analyst are recruited differently and confusing them costs you both.
- Put your scripting language on the page, as a security engineer who cannot write code is doing a different and lower-paid job.
- Evidence the advisory side, since much of the work is persuading developers to build securely without becoming the team that says no.
Why This Security Engineer Resume Works
This sample belongs to an eight-year security engineer working across cloud and application security, and its framing is the reason it reads as engineering rather than audit.
- The opening states the philosophy of the role plainly, building defence in rather than bolting it on, which is the actual distinction between engineering and assessment work.
- It leads on two outcomes rather than activities, closing major vulnerabilities across the estate and building automation that caught problems before release.
- Securing the CI/CD pipeline is called out specifically, and shifting security left into the build is the clearest marker of a modern security engineer.
- Building detection and response tooling is included, which shows the candidate creates capability for others rather than only consuming alerts from a console.
- Advising engineering teams appears as core work, and being someone developers will listen to is what separates an effective security engineer from an obstacle.
- The OSCP sits alongside cloud security certification, pairing offensive understanding with defensive platform depth, which is an unusually credible combination.
How to Write a Security Engineer Resume
The screen is looking for an engineer. Show artefacts you built, not findings you forwarded.
Lead with what you built, not what you found
Scanners wired into the pipeline, a secrets detection service, hardened base images, infrastructure-as-code security modules, custom detections. Anyone can run a scanner and forward the output; an engineer ships something that stops the problem recurring.
Name the cloud and the depth you have in it
Write AWS with IAM policy design, VPC architecture and GuardDuty, rather than cloud security experience. The three major platforms have genuinely different identity and network models, and employers screen against the one they run in production.
Quantify by attack surface removed
Critical vulnerabilities closed across an estate, mean time to remediate cut, a class of finding eliminated by a platform change, public endpoints reduced. Removing an entire category of weakness once beats remediating instances of it for years.
Show security in the build pipeline
SAST, dependency scanning, container image scanning, IaC checks, secrets detection, and the policy for what blocks a build versus what warns. Getting developers to accept a blocking gate is a political achievement as much as a technical one, so say how you did it.
Put your code on the page
Python, Go, Bash, and what you wrote in them. Security engineering is increasingly a software role, and the difference between someone who configures tools and someone who writes them shows up directly in the level and the salary band offered.
Evidence influence over developers
Threat models run with teams, secure defaults adopted, design reviews that changed an architecture, training delivered. Security engineers fail when developers route around them, so proving that engineering teams actually adopted your guidance is a genuine differentiator.
Security hiring runs through technical screens that start from the resume, so the stack and the artefacts need to be findable fast. You can build a technical security resume free and keep the detail readable rather than crammed.
What to Include in a Security Engineer Resume
Beyond the standard sections, a security hiring manager is scanning for these:
A cloud platform line per role, naming the provider and the specific services you secured or configured.
Tooling you built or ran, separating what you wrote yourself from commercial products you administered.
Vulnerability management outcomes, including volume closed, remediation time and any class of issue eliminated.
Pipeline security controls with the stage they run at and whether they block or warn on failure.
Programming and scripting languages with what you used them for, since this determines the level you are considered at.
Certifications and any public contribution such as CVEs found, tooling published or conference talks given.
Extra tips
Write "eliminated unencrypted volumes as a finding category by enforcing encryption at the platform level" rather than a count of tickets closed.
Removing a class of issue once is the difference between engineering and maintenance.
Security Engineer Resume Summary Examples
Two summaries at different levels, both leading with what was built rather than with a list of security concepts:
Entry-level resume summary example
Security engineer with two years in an application security team, moving across from three years as a backend developer and bringing production engineering experience with the security focus. Built and rolled out dependency and secrets scanning across forty-two repositories, tuning the rules down from an initial four hundred alerts a week to under thirty genuine findings developers actually action. Writes Python for internal tooling, including a service that flags publicly exposed cloud storage buckets and opens tickets automatically against the owning team. Holds CompTIA Security+ and is working toward the OSCP, with day to day work in AWS covering IAM policy review, security group audits and GuardDuty triage. Looking for a security engineering role on a team that builds its own tooling rather than only buying it.
Senior-level resume summary example
Senior security engineer with nine years across cloud and application security, currently owning the security platform for an AWS estate of around two hundred accounts serving a hundred and forty engineers. Rebuilt the organisation's cloud guardrails using service control policies and infrastructure-as-code modules, eliminating public storage exposure and unencrypted volumes as recurring finding categories entirely. Designed and shipped the CI/CD security pipeline covering SAST, dependency, container and IaC scanning, negotiating a blocking policy for critical findings that engineering teams accepted without an exemption backlog. Cut mean time to remediate critical vulnerabilities from thirty-one days to six by routing findings directly to owning teams with fix guidance attached. OSCP and AWS Security Specialty certified, seeking a staff security engineering role.
Security Engineer Work Experience Examples
Three sets covering the main specialisms, since cloud, application and detection engineering are recruited as distinct tracks.
Cloud security engineering
- Rebuilt the organisational cloud guardrails across an AWS estate of around two hundred accounts, using service control policies and reusable infrastructure-as-code security modules.
- Eliminated public storage exposure and unencrypted volumes as recurring finding categories entirely, by enforcing them at the platform level rather than remediating instances individually.
- Redesigned the IAM role structure and permission boundaries across the whole estate, cutting the number of identities holding administrative privileges from over ninety down to eleven.
- Deployed and tuned cloud-native detection across all accounts, integrating findings into the existing alerting pipeline so that ownership routing happened automatically on creation.
- Cut mean time to remediate critical cloud findings from thirty-one days down to six by routing each one directly to the owning engineering team with specific fix guidance attached.
Application security and DevSecOps
- Designed and shipped the CI/CD security pipeline covering static analysis, dependency scanning, container image scanning and infrastructure-as-code checks across all production repositories.
- Negotiated and implemented a blocking policy for critical findings that engineering leadership accepted, reaching full adoption without accumulating a backlog of standing exemptions.
- Tuned scanning rules down from an initial four hundred alerts a week to under thirty genuine findings, which is what made developers engage with the tooling rather than route around it.
- Ran threat modelling sessions with product teams ahead of every major feature, with two of those sessions leading directly to architecture changes before any code had been written.
- Built a secrets detection service in Python that scanned commit history across forty-two repositories and opened tickets automatically against the team owning each affected repository.
Detection and security tooling
- Built and maintained detection content mapped to the MITRE ATT&CK framework, expanding coverage across the techniques most relevant to the organisation's actual cloud architecture.
- Wrote internal tooling in Python and Go to automate evidence collection during incidents, cutting the manual gathering phase of an investigation from several hours to a few minutes.
- Integrated asset and ownership data into the alerting pipeline so that every single detection arrived with the responsible team already attached, rather than requiring a manual lookup.
- Reduced false positive volume on the ten noisiest detection rules by roughly seventy percent, through iterative tuning against observed production behaviour across two full quarters.
- Ran regular purple team exercises jointly with the detection and response function, using the results to close nine specific gaps in detection coverage that the testing had exposed.

Certifications for a Security Engineer
Security certification is a crowded field, so hold the ones that match the work you actually want to do:
-
OSCP
— OffSec A fully hands-on exam with real respect behind it. Offensive understanding makes defensive engineering sharper, and it is one of the few certifications technical interviewers treat as evidence.
-
Cloud Security Specialty Certification
— AWS, Microsoft or Google Match it to the platform you actually run. AWS Security Specialty, Azure AZ-500 or Google Professional Cloud Security Engineer all signal genuine platform depth rather than general awareness.
-
CISSP
— ISC2 Broad rather than deep, and it appears as a requirement on many senior job adverts. It matters more for management tracks than for hands-on engineering roles.
Security Engineer Salary
Security engineering sits at the higher end of the information security band, since the role requires software engineering ability alongside security knowledge:
USD 105,000 – USD 200,000 · Information security (engineering track) · US
National median around $129,180 across all information security roles. Engineering positions typically sit above that median, with analyst positions below it.
Common Security Engineer Resume Mistakes
These get a technically strong candidate filtered out before the interview:
- Listing security concepts and frameworks without a single thing you built, which reads as coursework rather than engineering experience.
- Writing cloud security with no platform named, when AWS, Azure and GCP have different enough models that the omission looks like inexperience.
- Reporting vulnerabilities found rather than closed, since finding problems is the easy half and employers are paying for the other one.
- Blurring engineer and analyst work together, which usually results in being screened out of both tracks rather than considered for either.
- Leaving programming languages off the page, which quietly places you in the tool-operator band rather than the engineering one.
- Collecting certifications with no practical work behind them, a pattern experienced interviewers spot within the first few technical questions.
Security Engineer Resume FAQs
The questions security engineers most often search when moving roles, answered directly:
Lead with cloud security on a named platform, infrastructure hardening and CI/CD security, then add your scripting languages and the tooling you built. Include threat modelling and vulnerability management, and keep the emphasis on things you implemented rather than concepts you know.
An engineer builds and hardens: pipelines, tooling, cloud guardrails and detections. An analyst monitors and responds: triaging alerts, investigating incidents and hunting threats. Engineers are judged on what they prevented, analysts on what they caught and how fast.
Describe the class of issue and the scale rather than the specific weakness or system. Something like eliminating public storage exposure as a recurring finding across two hundred accounts communicates real impact while disclosing nothing an attacker could use.
No, but it carries unusual weight because the exam is entirely practical. For defensive engineering roles a cloud security specialty certification on the platform you run is often more directly relevant, and the two together make a strong combination.
Name the provider and the specific services, such as AWS with IAM policy design, service control policies, VPC architecture and GuardDuty. Add the scale of the estate in accounts or workloads, because securing three accounts and two hundred are very different problems.
Lead with the engineering ability, since it is the harder half to teach and many security candidates lack it. Show security work you did in your existing role, such as fixing a vulnerability class or adding scanning to a pipeline, and add a platform-relevant certification.
