AI ENGINEER (CONTRACT-TO-HIRE)
Location: Remote (Global, EST working hours) Start Date: Rolling
Please apply using the provided form, candidates who directly email will not be considered.
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
HOW TO APPLY
Send us:
- A short note in the application form on why this role fits you Links to past work, projects, or GitHub.
- 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.
