Pulumi is headquartered in Seattle, WA. This role can be in Seattle or remote.

You’ll lead engineering efforts for Pulumi Copilot and Pulumi AI, integrating modern generative AI capabilities into the Pulumi Cloud to dramatically improve the developer experience.

This role is hands-on: we’re looking for a strong coder who can dive deep on implementation details, while also driving architectural direction, mentoring engineers, and helping set the AI strategy.

AI is evolving fast—we need someone who can keep pace with new developments and translate them into impactful product capabilities.

What You’ll Do

• Build agentic workflows and intelligent assistants that help users write infrastructure as code, troubleshoot issues, and manage resources more effectively.
• Collaborate across teams to help them surface their features and data to Pulumi AI, and help bring AI into their roadmaps.
• Lead architectural discussions and design/code reviews with actionable feedback.
• Stay up to date on the latest in GenAI and apply it pragmatically to ship real value.

What We’re Looking For

• 8+ years of professional software engineering experience, ideally in infrastructure, distributed systems, or developer platforms.
• Proficient in one or more imperative languages (e.g., Python, Java, Go, C++, etc.)—you’re comfortable writing and reviewing production-quality code.
• Demonstrated leadership experience—mentoring, guiding architecture, driving initiatives forward.
• Strong collaboration and communication skills.

Bonus if You Have

• 1+ years of experience in GenAI: working with LLMs, chat interfaces, agentic systems, RAG pipelines, or vector databases.
• Experience building developer-focused products or internal developer platforms.
• Contributions to open source projects, or public demos of AI/dev tooling work.
• A passion for shipping iteratively in a fast-paced, evolving space.

Compensation:

• Base Salary Hiring Range:  $180,500 - $227,850
