Application AI Engineer (Contract-to-Hire)
Location: Remote (Global)
Start Date: Rolling
Compensation: $75/hour for first 4 weeks (contract-to-hire trial)

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
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.
