About the role
GitLab is the intelligent orchestration platform for DevSecOps, and the Security Factory: Code Security team builds GitLab's code-level security scanning capabilities, spanning static application security testing (SAST) and dependency scanning. The team works closely with the Static Analysis team on GitLab's SAST engines and with Composition Analysis on the broader software supply chain, relying heavily on asynchronous work across time zones. This Intermediate Backend Engineer role connects dependency analysis, vulnerability detection, and automated remediation — building parsing for dependency manifests, lockfiles, and SBOMs, extending a service that turns security advisories into dependency update merge requests, and developing hybrid analyzers that combine rule-based detection with AI reasoning.
What you will do
- Develop secure, well-tested, performant parsing for dependency manifests, lockfiles, and software bills of materials (SBOMs). Extend support for new package ecosystems and formats in the analysis engine and remediation service.
- Build and apply analyzers that combine deterministic analysis with AI-driven analysis, working with the team's technical leadership. Review their results and measure false positives and missed findings against benchmark applications with known vulnerabilities.
- Create detection rules mapped to Common Weakness Enumeration (CWE) and the test fixtures that prove they work.
- Contribute to packaging analyzers for continuous integration (CI) jobs, AI agent workflows, and command-line tools, reporting findings in GitLab's standard security report formats.
- Extend the automated remediation service, from running dependency updates in a sandbox to opening merge requests.
- Solve technical problems of moderate scope and complexity. Identify technical debt that slows the team down, and propose and implement improvements.
- Write maintainable code that meets our internal standards, and help maintain those standards through code review.
- Participate in on-call rotations to troubleshoot product operations, security operations, and urgent engineering issues.
Skills used in this role
What the employer is looking for
- Experience using AI or large language model (LLM) tools to generate or evaluate technical content, with the judgment to know when output is trustworthy and when it isn't.
- Solid professional experience writing and testing production code in a systems language, particularly Go and/or Rust. We use both, plus Ruby for remediation and Python for some analyzers, and value a willingness to work across them.
- A willingness to learn how vulnerabilities arise in code and the software supply chain, explore common vulnerability classes such as the Open Worldwide Application Security Project (OWASP) Top 10 and CWE, and apply static analysis to detect them. Deep expertise isn't required, and we'll help you develop it.
- The ability to organize your work and follow through on tasks independently in a remote, largely asynchronous environment.
- The ability to communicate clearly and concisely about technical problems and propose iterative solutions.
- Helpful, but not required: experience with containerized workflows and continuous integration and continuous delivery (CI/CD), or a willingness to learn them; package managers and dependency tooling such as npm, Maven, pip, Bundler, or Cargo; web or mobile frameworks; parsing, abstract syntax trees (ASTs), program analysis, or detection rules; or evaluating AI-driven detection against labeled data. We use Docker heavily.
