Senior Software Engineer, Test Infrastructure

Responsibilities

• Own the architecture and core of the test-orchestration platform, including the distributed task scheduling, execution, and result-collection engine that runs tests across manufacturing and the fleet.
• Personally build the most complex, reliability-critical components.
• Lead a small engineering team of two engineers plus 1–3 contractors: setting technical direction, reviewing code, and growing the team's impact.
• Make the platform resilient at scale: design for safe mid-run cancellation, no result loss under failure, and predictable behavior across hundreds of test runs.
• Build clean APIs and frameworks that let other teams plug their own test suites into the platform without forking it.
• Partner across the company with multiple teams to ship test tooling that production and validation campaigns depend on.

Requirements

• 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.
• Demonstrated ability to design and maintain test frameworks for large codebases (deep pytest experience: fixtures, parametrization, scalable suites).
• 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).
• Experience as a technical lead or architect - owning a system end to end, setting direction, and reviewing/mentoring other engineers' work.

Nice-to-Haves

• Experience with Bazel (or another large-monorepo build system with hermetic/reproducible builds).
• Experience deploying and operating services on AWS/Kubernetes (EKS, Helm, ArgoCD).
• Experience with observability tooling (OpenTelemetry, Grafana/Prometheus).
• Background in manufacturing, hardware, or vehicle test systems (CAN/DoIP, Automotive Ethernet, HIL).
• Experience working with cross-functional production teams.
