Senior Software Engineer (Core Backend & Platform Engineering)

About this role

• Technology is at the core of what we do. Basis is an industry-leading platform that automates and simplifies the entire digital ad campaign process. It processes over 300 billion events per day and uses AI and machine learning across the full campaign lifecycle
• The Core Backend team is the connective tissue that keeps Basis running and lets other engineering teams move faster. We own the health of our core backend, the core customer-facing features developed within it, and the systems and standards that feature teams build on top of — along with the strategy for how the application evolves over time
• That includes performance and reliability, observability foundations, release tooling, and the strategy for decomposing the system into well-defined microservices

• 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 a...
