## Description

### 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.
