Senior Software Engineer, Agent Platform (AI for the Planet)

We are seeking a Senior Software Engineer to join our team at the Allen Institute for AI, part of AI for the Planet. As a Senior Software Engineer, Agent Platform, you will work on building a platform for conservation groups, government agencies, and research organizations that want to run AI agents against their own systems.

Responsibilities:

• Build and evolve the platform's core capabilities and interfaces.
• Own the experience of authoring agents on the platform, from the first build all the way through production deployment.
• Build the UI, CLI, and SDK that authors use to deploy agents, run evals, and understand what happened.
• Develop our own internal agents on the platform and operate them in production.
• Write the docs, quickstarts, and example agents that get an outside developer from an idea to a running agent.
• Decide with the team what to work on next, and fix what blocks users before starting larger features.
• Write small tools and skills that make the team faster.

Requirements:

• 8+ years of professional software engineering experience.
• Experience across the stack: web UIs, backend services, CLIs, and cloud tooling.
• A track record of shipping products to external users and talking with those users directly.
• Good judgment about priorities: you fix blockers first and keep scope small.
• Clean, tested code, and experience reviewing other people's code.
• Opinions about API design, and a preference for simple designs over clever ones.
• Daily use of AI coding tools such as Claude Code, including writing your own skills or tools.
• Willingness to write documentation as part of the work rather than after it.
• Clear technical communication with engineers and non-engineers.

Nice to Have:

• Experience building developer tools, CLIs, SDKs, or public APIs for outside users.
• Experience building or running LLM agents, including prompts, tools, and evals.
• Experience building evaluation or experimentation systems.
• Small or growth-stage company experience.
• Public technical work such as open source contributions, writing, or side projects.
• Willingness to travel on occasion.

Benefits:

• Generous bonus plans
• Competitive compensation package
• Opportunities for learning and growth
• Collaborative and transparent work environment
• Emphasis on healthy work/life balance
• Paid vacation and sick leave
• Family leave
