Software Engineer - Builder Platform

• Develop and operate our Agent Platform for deploying, running, evaluating, governing, and improving agents and agentic workflows.
• Establish and operate the AI Infrastructure that agents depend on: LLM and MCP gateways with guardrails, fallback, usage and cost controls, and model rollout policies.
• Build and operate agents and workflows that carry engineering work from issue to production and business work from trigger to outcome, with humans governing the boundaries.
• Own our Developer Infrastructure (Source Control and CI) and build the developer tools that improve builder flow and reduce friction across the company.
• Partner with teams across Engineering, Product, Sales, and G&A to understand where AI could accelerate their work or improve the quality of outcomes.
• Drive adoption of agents and agentic tooling across the company, and own the best practices and enablement materials that help builders succeed using the paved roads.
• Build measurement and feedback loops (usage, reliability, and cost) to quantify the productivity the platform unlocks and guide the roadmap.
• Treat Temporal as customer zero: turn what we learn into validated requirements for Temporal Cloud, the SDKs, and our Agent Harness, and contribute to an open-source reference architecture that customer platform teams can adopt.
• Participate in on-call to support internal users.

• 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.
