Autonomous vehicles have some of the largest, most complex software ever shipped in a safety-critical environment. Solving that problem is one of the most exciting technical challenges of our lifetime.
As a Software Development Engineer in Test on the Release Management team at Zoox, you will help accelerate our software release by ensuring that we are shipping the safest and most reliable software possible. As developers build new features, you will be responsible for building and maintaining tooling to measure the performance of various software components. You will also play a key role in developing Hardware-In-Loop tests, measuring system performance, and escalating issues seen during on-vehicle and offline testing. These efforts are critical to maintaining our code quality and ensuring our service capabilities are operating as intended. Your ability to understand the overall system design and component interaction to help guide test methodology for functional and safety sign-off is crucial to the overall success of our team. Accountability and integrity are core to our team.
In this role, you will:
- Build and maintain tooling on Hardware-in-the-Loop assets to measure the performance of different software components during the Integration and Acceptance testing phase.
- Lead investigation of performance issues arising due to recent code changes before release sign-offs.
- Monitor and analyze performance results from both offline (Hardware-in-the-Loop test runs) and on-vehicle logs, and develop automated performance reporting.
- Triage and identify software regressions and possible improvements for development teams.
- Be the quality gate for software performance before qualifying a release candidate.
Qualifications:
- Bachelor’s or Master's degree in Engineering, Computer Science, Mathematics, or related field, with a minimum of 5 years of experience in complex testing environments (Consumer Electronics, Automotive, Aerospace, or related industries).
- Experience with developing automated functional test software on Hardware-in-the-Loop infrastructure.
- Deep knowledge of software testing methodologies and experience in developing, executing, and automating performance and latency testing.
- Understanding of software system performance concepts (CPU, GPU, IO, memory tradeoffs, job scheduling, networking).
- Expert Python programming experience with a focus on system-level tests and test framework development.
Bonus Qualifications:
- Prior experience with the rigorous verification and validation of complex robotics and safety-critical software systems with a focus on performance measurements.
- Proficiency with Github, CI, and Jira.
- Experience using Linux perf to identify performance bottlenecks.
