Software Development Engineer In Test

Software Development Engineer In Test

Clockwork Systems was founded by Stanford researchers and veteran systems engineers who share a vision for redefining the foundations of distributed computing. As AI workloads grow increasingly complex, traditional infrastructure struggles to meet the demands of performance, reliability, and precise coordination. Clockwork is pioneering a software-driven approach to AI networking, delivering deterministic time, ultra-low latency, and seamless scalability for modern distributed systems.

We are looking for a Software Development Engineer in Test who thrives in fast-paced startup environments and is excited to own our entire testing and CI/CD infrastructure. You will play a critical role in ensuring the quality and reliability of every release before it reaches our customers.

This is a hands-on engineering role, not a manual QA position. You'll be deeply embedded in our engineering team, responsible for building robust automation, maintaining pipelines, and contributing directly to the product during quieter times.

Responsibilities

• Design, build and maintain integration and regression tests for distributed systems
• Own and maintain the CI/CD testing infrastructure and pipeline
• Ensure all code releases meet high quality standards before shipping to customers
• Collaborate closely with engineers to identify gaps in test coverage and build tools or frameworks to fill them
• Investigate and diagnose build failures, flaky tests, and regressions.
• Contribute to engineering efforts beyond QA when appropriate (feature development, tooling, etc.)

Qualifications

• 3+ years of experience in a Test Engineering, DevOps, or QA role with a strong technical background
• Demonstrated expertise in building automated test scripts using a programming language of your choice
• Proven experience with CI/CD tools such as Jenkins, GitHub Actions, GitLab CI and testing frameworks such as pytest, playwright etc.
• Familiarity with containerization and orchestration (Docker, Kubernetes) is a plus
• Experience with cloud infrastructure and distributed systems is a plus
• Strong debugging, problem-solving, and communication skills
• A startup mindset — self-motivated, adaptable, and eager to take ownership

Why Join Us

• Be part of a foundational team shaping the future of infrastructure software
• Work onsite in a collaborative environment in Palo Alto
• Opportunity to grow into broader engineering roles

Enjoy challenging projects. A friendly and inclusive workplace culture. Competitive compensation. A great benefits package. Catered lunch.
