Intermediate Backend Engineer , Security Factory

GitLab is hiring a Intermediate Backend Engineer , Security Factory in Bangalore, India. The details below summarise the employer's own listing; applications happen on the original posting, not on GetFirstJob.

What the work involves

• Extend the program model, including parsing, symbol resolution, intermediate representations, call graphs, and taint and data-flow analysis, to support new languages and frameworks.
• Build and apply AI-assisted tooling to implement, review, and validate engine changes and findings, in collaboration with the team's technical leadership. Measure detection quality against known vulnerabilities, judging changes primarily on false positive and false negative rates.
• Develop static application security testing (SAST) rules mapped to Common Weakness Enumeration (CWE) and the Open Worldwide Application Security Project (OWASP), along with test fixtures that demonstrate they work.
• Implement component specifications with engineers and AI agents through phased plans and small, reviewable changes. Keep specifications and code in sync.
• Improve the harness, agent instructions, and skills that keep agent-written code trustworthy. Use separate coding and reviewing agents, performance checks, application programming interface (API) checks, and dependency checks, and escalate risky changes to human review.
• Solve technical problems of moderate scope and complexity, and identify and address technical debt that slows the team down.
• Write maintainable code that meets our internal standards, and help maintain those standards through code review.
• Participate in on-call rotations to help troubleshoot product operations, security operations, and urgent engineering issues.

What they are looking for

• Solid professional experience writing and testing production code in a systems language, particularly Rust or Go. Our engine is written in Rust, the analyzer wrapper in Go, and the monolith integration in Ruby. You'll be willing to work across them.
• An interest in static analysis and application security, including parsing, intermediate representations, taint and data-flow analysis, and how vulnerabilities arise in code. Deep expertise isn't required; we'll help you grow it.
• Organize and progress your work independently in a remote, largely asynchronous environment.
• The ability to communicate technical problems clearly and concisely and propose iterative solutions.
• Helpful but not required: experience with performance optimization, Docker and continuous integration and continuous delivery (CI/CD), web or mobile frameworks, guardrails for agent-written code such as mutation testing and fuzzing, or program analysis and security research through publications or open source contributions. Willingness to learn performance optimization and containerized workflows is also welcome.
• Benefits to support your health, finances, and well-being
