GitLab - Staff Software Engineer, Security Factory: Static Analysis

• 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 • Extensive professional experience writing, testing, and reviewing production code in Rust, Go, or a comparable systems language, with depth in at least one. The engine is Rust, the analyzer wrapper is Go, and the monolith integration is Ruby, and we value willingness to work across them. • Experience with performance optimization and with containerized workflows and CI/CD (we use Docker heavily) • A deep program analysis and static analysis background, such as parsing and ASTs, intermediate representations (SSA, control-flow and call graphs), taint and data-flow analysis, type inference, incremental and fixpoint computation, or writing detection rules, with the ability to read, evaluate, and apply the research literature • Deep application security experience, such as vulnerability research, secure code review, or writing detection rules, and fluency with vulnerability classes (OWASP Top 10, CWE) • Demonstrated capacity to communicate clearly and concisely about complex technical, architectural, and organizational problems, and to write architecture and design specifications that bring a team to a decision • A track record of taking ownership of ambiguous, team-wide problems and shipping them from concept to production with minimal guidance, with specific, regular async updates on progress, blockers, risks, and next steps • Experience defining a system's overarching architecture, delegating component specifications to engineers and AI agents, and getting them implemented reliably • A track record of mentoring engineers, raising a team's technical bar, and influencing technical direction by achieving consensus with peers and leadership • Familiarity with popular web or mobile application frameworks and how they handle input, data, and configuration • Experience designing guardrails for agent-written code, such as mutation testing, fuzzing, and CI gates the coding agent cannot modify • A record of engaging with the research community, such as publications, tool papers, or upstream open source contributions in program analysis or security • The Security Factory: Code Scanning team develops GitLab's SAST capabilities for customer software repositories. • We work closely with the Code Security team on scanning rules & flows, 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.
