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.
This is a contract-to-hire role. The first month is a paid trial at $75/hour. If there’s mutual fit, you’ll transition to a full-time or retainer-based role within the core team.
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
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
- 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
- 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
Send us:
- A short note in the application form on why this role fits you Links to past work, projects, or GitHub.
