Sr Software Engineer - Core Backend & Platform Engineering

Contribute to the platform's performance, observability, and reliability standards, and help drive adoption across feature teams.  

Reshaping how we build and ship: CI/CD, trunk-based development, and developing a layered testing strategy (unit, integration, contract, end-to-end) so teams can test in isolation and deploy independently. 

Collaborate closely with the Enterprise Developer Experience team to build shared tooling. 

Improve the developer and pre-production experience for the core backend — pipeline design, environment stability, and a fast development feedback loop. 

Lead platform projects across the stack — release tooling, platform reliability, and the patterns that guide how we decompose the core backend into services. 

Take ownership of deliverables, quality, and on-call support across our systems and components, and drive projects from ideation through production. 

Actively partner with the feature teams who depend on the systems you own — through pull requests, demos, design discussions, and identifying risks and blockers early. 

5+ years of professional software engineering experience. 

Experience developing large-scale cloud-native systems — reliability, scalability, and the observability that keeps them healthy. 

Depth in modern software delivery: CI/CD, trunk-based development, layered automated testing, and release practices like feature flagging, canary deployments, and progressive delivery. 

Experience contributing to org-wide standards — testing strategy, environment management, performance and SLOs. 

Fluency with AI coding tools (Claude Code, Cursor, Codex, etc.) as a core part of your development workflow — for code generation, debugging, exploring unfamiliar codebases, and documentation — paired with strong judgment for evaluating, refining, and taking full ownership of AI-generated output. 

A thoughtful, collaborative approach to design and decision-making, and a commitment to inclusive environments where all voices are valued.
