Experience with large monoliths is helpful. ## Description As a Senior Software Engineer, you'll work across two important areas for GitLab Security: the data layer behind our vulnerability and dependency management capabilities, and our move toward services outside the GitLab monolith. You'll design and develop systems that ingest, store, index, and query security report data, including integrations with key third-party systems. With a strong focus on PostgreSQL and scalable backend design, your work will support security features that teams across GitLab deliver. You'll own significant parts of larger deliverables from design through delivery. You'll shape the approach with your tech lead, drive execution and decisions within your scope, and stay hands-on across GitLab's Ruby on Rails application and newer services, including greenfield projects. You'll also grow into a domain expert on the database systems that underpin this suite. What you'll do * Own significant components of larger deliverables, from technical design through delivery, and deliver iteratively within GitLab's monthly release cycle by showing progress and raising constraints early. * Design and develop backend systems for vulnerability and dependency management, including security report ingestion, storage, indexing, querying, and integrations with key third-party systems. * Build and improve systems using Ruby on Rails and PostgreSQL, and contribute to newer services using technologies such as Go or Rust where appropriate. * Develop deep PostgreSQL expertise by improving queries and schemas as the data behind vulnerability management continues to grow. * Collaborate directly with product, design, frontend, and engineering partners on decisions within your scope. * Contribute to technical plans and design discussions, and support other engineers through reviews, pairing, and clear documentation. * Apply a security mindset when designing systems, including how GitLab identifies and handles malicious or vulnerable software packages. * Contribute to GitLab's move toward modular services as the team establishes these patterns for GitLab Security., LinkedIn Profile Are you subject to any employment agreements and/or post-employment restrictions with your current employer or a past employer?* Select...
