Senior Software Engineer (Test Infrastructure)

Join Zoox, a company dedicated to revolutionizing transportation. As a Senior Software Engineer, you will own the architecture and core of our test-orchestration platform, lead a small engineering team, and partner with multiple teams across the company. You will design for resilience at scale, build clean APIs and frameworks, and contribute to the success of our production and validation campaigns. Enjoy a range of benefits, including paid parental leave, health insurance, and a vibrant work environment.

• Architect and develop the core of the test-orchestration platform, focusing on distributed task scheduling, execution, and result collection.
• Lead a small engineering team, setting technical direction, reviewing code, and mentoring team members to enhance their skills and impact.
• Design and implement features to ensure the platform's resilience at scale, including safe mid-run cancellation and predictable behavior across test runs.
• Experience as a technical lead or architect - owning a system end to end, setting direction, and reviewing/mentoring other engineers' work
• Demonstrated ability to design and maintain test frameworks for large codebases (deep pytest experience: fixtures, parametrization, scalable suites), and to design REST and library/framework APIs that other engineers build on
• Solid software-engineering and distributed-systems fundamentals - systematic debugging across services, networking (HTTP, TCP/IP, container networking), CI/CD pipelines, Docker, and relational databases (PostgreSQL)
• Strong production Python, including hands-on experience building distributed task/queue systems (e.g., Celery or equivalent) with a message broker and result backend (Redis / RabbitMQ) - task lifecycles, retries, cancellation, and worker reliability
• Experience with Bazel (or another large-monorepo build system with hermetic/reproducible builds)
• Experience deploying and operating services on AWS/Kubernetes (EKS, Helm, ArgoCD) and with observability tooling (OpenTelemetry, Grafana/Prometheus)
• Background in manufacturing, hardware, or vehicle test systems (CAN/DoIP, Automotive Ethernet, HIL) and working with cross-functional production teams
