About the role

Baseten is hiring a Software Engineer to own and build the testing stack for the Platform team, focusing on unit, integration, load, performance, and resilience testing frameworks, with a emphasis on creating reusable tooling, improving test reliability, and raising the org-wide testing standards.

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 — ephemeral 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.

Qualifications

  • Strong proficiency in Go and/or Python, with hands-on experience building test tooling and libraries used by other engineers.
  • Deep experience with testing frameworks and their internals — pytest, Go's testing package, testify, testcontainers, or equivalents — including the ability to extend them, not just use them.
  • Experience designing integration test infrastructure for distributed systems, including ephemeral environment provisioning and dependency management.
  • Practical experience with load and performance testing tools (k6, Locust, Vegeta, JMeter, Gatling, or similar) and the ability to interpret results and drive action from them.
  • Solid Kubernetes and Docker fundamentals — you can build test infrastructure that runs on and tests against real cluster environments.
  • Advanced understanding of CI/CD, including how to keep large test suites fast, deterministic, and trustworthy at scale.
  • A track record of measurably improving testing culture on an engineering team — you have opinions on what to test, what not to test, and where the ROI actually is.
  • Are excited about building foundational infrastructure and are comfortable working independently on ambiguous, high-impact technical challenges.
