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 Gravity our in house software factory and agent hub that we use to build all software.
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-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. 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, 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 and add features to Gravity, our software factory platform.
•
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, and a deep familiarity with what it takes to make them work well in production environments.
•
Experience with frontend development (React, Next.js, etc.)
•
A background in a STEM discipline, data science, or quant-heavy engineering you’ll need to be able to show the impact of your work with statistical significance
•
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
