Senior Software Engineer, Builder Tools

Join our Builder Tools Team as a Senior Software Engineer. Our mission is to empower a company of builders by delivering a frictionless, standardized ecosystem of core engineering tools.

As a Senior Software Engineer, you will build and maintain internal engineering tooling that improves builder flow and reduces friction across the company. You will provide guidance, best practices, and automation to support adoption of AI agentic coding tools.

Key responsibilities include:

• Building and maintaining internal engineering tooling that improves builder flow and reduces friction across the company.
• Providing guidance, best practices, and automation to support adoption of AI agentic coding tools.
• Developing and operating internally facing agents.
• Implementing and improving developer workflows, including guardrails, evaluation approaches, and guidance that enables safe adoption of new tooling.
• Owning development and operation of our internal agent platform.
• Partnering with teams across Engineering, Product, Sales, and G&A to understand where AI could accelerate their work or improve the quality of outcomes.
• Building measurement and feedback loops (usage, reliability, cost, and cycle time) to quantify impact and guide iteration.
• Owning documentation and enablement materials that help builders succeed using the paved roads.

Requirements include:

• Strong software engineering fundamentals and experience shipping and operating production-quality internal platforms or developer tooling.
• Experience leveraging modern agentic coding tools such as Codex and Claude Code.
• Proficiency in one or more programming languages commonly used at Temporal, such as Go, TypeScript/JavaScript, Python, or Java.
• Experience building workflow automation or internal tools (CLI tools, services, GitHub automation, cloud automation, or similar).
• Strong judgment about when to standardize versus when to enable flexibility, and how to remove friction without compromising reliability.
• Comfort working cross-functionally, including partnering with non-traditional developers and translating needs into usable solutions.
• Ability to use data and qualitative feedback together to prioritize and measure impact.
• Clear written communication, including documentation that enables self-service.

Nice to haves include experience building internal agents and operating an agent platform, familiarity with developer productivity measurement frameworks such as SPACE and DORA metrics.
