Full Stack AI Engineer Full Time

The Role
We’re looking for scrappy, sharp, execution-focused engineers who thrive in high-context, high-autonomy environments. You’ll be deployed on fast-moving projects—from validating ideas in one-week sprints to helping scale production tools inside early-stage companies.

What You’ll Do

• Build working prototypes of agentic AI applications, LLM workflows, and full-stack products
• Experiment quickly across frameworks (e.g. LangChain, CrewAI, AutoGen), open source tools, and low-code stacks
• Interface directly with product thinkers and founders to distill ambiguous ideas into testable code
• Contribute to shared internal libraries and the Infinity Commons
• Occasionally embed with portfolio companies to support launches or unblock execution

What We’re Looking For
Required:

• Fluency in Python and experience using AI toolkits and APIs
• Experience rapidly building and iterating on proof-of-concept or MVPs
• Comfort using a blend of commercial APIs, open source, and low-code tooling to get things done
• Strong problem-solving skills and analytical intuition

Bonus Points:

• Prior work with AI agents, vector databases, or retrieval-augmented generation (RAG)
• Experience with frontend development (React, Next.js, etc.)
• A background in a STEM discipline, data science, or quant-heavy engineering
• Previous experience in a venture-backed startup or technical founder role

How We Work

• Asynchronous by default, with tight feedback loops and clear ownership
• High-trust, high-autonomy culture that values shipping, learning, and iterating
• Small, elite team of senior builders with experience across AI, product, and infrastructure
