Role: Founding Engineer / Member of Technical Staff
Location: New York City (in-office)
Compensation: $150k–$250k base + meaningful equity
Stage: Venture-backed, early-stage AI company
Why this role
- One of the first engineers in a newly funded AI company

- Work directly with the founder on product and architecture
- Ship real AI systems used in production from day one
What you’ll be doing
- Building backend and product systems in a 0→1 environment
- Integrating LLMs and agents into real workflows
- Designing systems that handle real-time decisioning and user interaction
- Shipping quickly in a small, high-ownership team
Tech

- TypeScript / Next.js
- Cloud (GCP or AWS)
- LLMs, agents, embeddings
What we’re looking for
- Strong backend or full-stack engineer
- Experience building real systems in production
- Clear, structured thinker who can explain what they’ve built
- Comfortable in fast-moving, early-stage environments
Ideal background
- Startup experience or strong product ownership
- Exposure to AI systems (LLMs, agents, or similar) is a plus
- Typically early to mid-career engineers who want to move faster and own more
Who this suits
- Engineers who want ownership, speed, and impact
- Prefer small teams over large organisations
- Want to build from first principles, not iterate on legacy
Compensation
- $150,000 – $250,000 base
