О компании и продукте

• As a Staff Backend Engineer at GitLab, you will help shape a major investment in our Software Supply Chain Security offering. In this role, you'll serve as a senior technical leader for backend systems that help customers secure how software is built, verified, and delivered inside the GitLab platform. You'll work on foundational capabilities across package policy enforcement, build provenance, artifact signing, and malicious package detection, with a strong focus on enterprise-grade security and performance.
• You'll define architecture before systems are built, write clear technical proposals, and guide implementation across interconnected parts of GitLab such as CI/CD, dependency management, and security workflows. This role is a strong fit for someone who enjoys solving complex backend problems, influencing technical direction across teams, and building security features that matter to customers facing real threats. You'll do this in GitLab's remote, asynchronous, and values-driven environment, where written communication, ownership, and teamwork are central to how we work.
• Some examples of our projects:
• Dependency Firewall for package policy enforcement across supported registries
