Senior Software Developer, AI Platform

7+ years of experience in software development as part of a team, with meaningful experience in platform engineering, developer experience, or developer tooling, and a growing track record building AI-powered or LLM-driven systems.

Hands-on experience building with LLMs and AI tooling. You've explored and worked in the AI space, whether building LLM-powered developer tools, integrating AI APIs, or experimenting with agents and automation. You understand the practical realities of working with models like Claude in production systems.

A product mindset for internal platforms. You treat developer tooling as a product, with engineers as your customers. You're driven to understand their pain points, measure adoption and impact, and build solutions that stick.

Technical versatility across a polyglot stack. Experience with two or more of Ruby, Python, TypeScript, or Java/Kotlin. You're comfortable writing tooling and automation across different language ecosystems.

Experience building governance, policy, or guardrail systems. You've thought carefully about how to build systems that enforce standards at scale without getting in developers' way.

Data-informed decision-making. You use metrics to identify opportunities, measure impact, and prioritize. You're comfortable establishing baselines, setting targets, and tracking progress toward goals.

Strong cross-functional collaboration skills. You build trust with partner teams, communicate clearly about progress and trade-offs, and know how to drive alignment across an organization.

A collaborative spirit and passion for mentorship. You invest in the growth of your colleagues and are comfortable presenting technical ideas to diverse audiences.
