About The Project We're building AI-native engineering team within
Infinity , a holding company building full-stack AI businesses. We support portfolio companies by:
Rapidly prototyping new product ideas to validate markets
Providing flex capacity during high-growth phases
Maintaining and evolving the
Infinity Commons , our shared library of frameworks, prompts, and reusable tools
We’re not a dev shop. We’re a surgical team of builders who move fast, reduce ambiguity, and create leverage across a network of founders building with AI at the core.
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
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

Availability to start the contract phase
We’ll move quickly. If it feels like a fit, you’ll be coding real things with us within a week.
