GitLab - Senior Software Engineer, Security Factory: Code Security

• Experience building your own LLM tooling, such as a harness, an agent pipeline, or evaluations, with the judgment to know when output is trustworthy and when it isn't • Substantial professional experience writing and testing production code in a systems language, particularly Go and/or Rust, with depth in at least one. We use both, plus Ruby on the remediation side and Python for some analyzers, and value willingness to work across them. • Familiarity with package managers and dependency management in one or more language ecosystems, such as npm, Maven, pip, Bundler, or Cargo. Experience building tooling around them is better still. • Demonstrated application security experience, such as vulnerability research, secure code review, or writing detection rules, and fluency with vulnerability classes (OWASP Top 10, CWE) and the software supply chain • A track record of taking ownership of ambiguous problems and shipping with minimal guidance, with the self-motivation and organizational skills suited to a remote, largely asynchronous environment • Demonstrated capacity to communicate clearly and concisely about technical problems, and to write design proposals that bring a team to a decision • Experience evaluating AI-driven detection against labeled data, including measuring false positives and missed findings • Experience with performance optimization at scale • Hands-on program analysis experience, such as parsing, ASTs, or data-flow analysis • Familiarity with popular web or mobile application frameworks and how they handle input, data, and configuration • Experience with containerized workflows and CI/CD (we use Docker heavily) • The Security Factory: Code Security team builds GitLab's code-level security scanning capabilities, spanning static application security testing and dependency scanning. We help developers find and fix security issues in both the code they write and the open source components they depend on, as early as possible. • We work closely with the Static Analysis team on GitLab's SAST engines, with Composition Analysis on the broader software supply chain, and with other groups across the Sec Section. We rely heavily on asynchronous work across time zones. • The base salary range for this role’s listed level is currently for residents of the United States only.
