Job summary

Baseten is hiring a Software Engineer focused on testing within the Platform team. You will own the end-to-end testing strategy, building unit, integration, load, and performance testing frameworks for a mission-critical AI inference platform.

You will design end-to-end test infrastructure, implement resilience and chaos testing, and drive test reliability across the organization. This role emphasizes building foundational infrastructure and mentoring engineers in testing best practices.

Qualifications

• Proficient in Go and/or Python with test tooling experience.
• Experience with distributed systems integration tests and environment provisioning.
• Familiar with CI/CD and building maintainable test suites.

Responsibilities

• Own Baseten's testing strategy end to end — define the standards, the tiers, and the tooling that engineering teams build against.
• Build and maintain unit, integration, load and performance testing frameworks
• Design end to end test infrastructure that provisions realistic dependencies on demand — ephemer Kubernetes namespaces, containerized service dependencies, etc.
• Build resilience and chaos testing capabilities: fault injection, network partition and latency simulation, pod and node failure scenarios, dependency degradation, and automated verification that our systems degrade gracefully and recover.
• Attack test suite reliability head-on — flake detection and quarantine, test impact analysis and selective execution, parallelization, and aggressive reduction of end-to-end CI wall time.
• Build observability into the testing layer itself: coverage reporting, test health dashboards, failure triage tooling, and clear signals about which areas of the codebase are under-tested.
• Create project templates and shared libraries so new services start with a complete testing setup on day one.
• Partner directly with product and infrastructure teams — embed where needed, understand their hardest testing problems, and turn one-off solutions into platform capabilities.
• Mentor engineers across the org on testing practice and raise the collective bar through code review, documentation, and internal advocacy.
