Principal Test Automation Engineer

The role

You will define and build AI-enabled automation across the software development lifecycle including build, CI, testing, and release. You will set technical direction for workflow automation and build foundations like agent harnesses and tool integrations.

What you will do

• Set the technical direction for AI-enabled workflow automation across build, CI, test, and release.
• Build the shared foundation, including the agent harness and tool integrations into GitLab, Jira, test results, logs, and observability data.
• Develop evaluation methodology to measure whether an automation saves time and preserves correctness.
• Define guardrails and standards for where AI acts autonomously and where a human decides.
• Deliver Quality Engineering automations including cross-layer failure attribution and coverage-gap analysis.
• Raise the bar across engineering through shared patterns, design reviews, and mentoring.
• Determine when an agent, a deterministic tool, or a simple script is the right solution.

Required qualifications

• Extensive production software engineering experience
• Strong Python skills
• Rust and/or C++ experience to understand build flows and diagnose compiler errors
• Experience shipping AI-enabled tools or automation that others relied on in production
• Deep hands-on experience with LLM APIs, agent harnesses, tool integration, and context engineering
• Experience designing evaluations for nondeterministic systems
• Sound judgment about when AI is the right tool
• Strong fluency across the development lifecycle, including CI/CD, testing, and release processes
• A track record of setting technical direction across teams that do not report to you

Nice to have

• Exposure to compilers, firmware, or hardware-in-the-loop test environments
• Experience building tool integrations with MCP or similar protocols
• Experience working with GitLab, Jira, or Prometheus APIs
• Experience managing cost and latency in LLM-based systems
• Daily use of AI coding tools such as Claude Code, Cursor, or Copilot
