Full Stack Developer

We’re building the AI front office and field guidance platform for the HVAC industry.

Today, HVAC companies lose countless hours to admin work, expert knowledge walks out the door when technicians retire, and apprentices can take 5+ years before they’re fully productive.

We’re changing that.

We’re building an AI-powered operating system that captures that expertise, automates back-office operations, and delivers real-time guidance through computer vision and AR.

Coffee AI combines AI, Computer Vision, Knowledge Graphs and AR to help skilled trades businesses operate more efficiently while putting decades of expertise directly into the hands of the next generation of technicians.

Think AI receptionist + AI dispatcher + AI field expert in your ear.

We’re early.

Pre-seed. Pre-revenue. Building from the ground up.

We’re looking for a Founding Engineer who wants to help build something that genuinely matters.

The Stack:

• FastAPI

• Next.js

• AI Agents

• Computer Vision

• Knowledge Graphs

• AR/Spatial Computing

• Cloud Infrastructure

You’ll:

• Build core AI products from zero to one

• Work directly with the founder on product and technical strategy

• Develop computer vision and knowledge systems for real-world field use

• Help shape the future of AR-assisted skilled trades

• Own major technical decisions from day one

You are:

• A builder first

• Comfortable working across the full stack

• Curious about AI beyond just LLM wrappers

• Interested in Computer Vision, AR, Robotics or Spatial Computing

• Excited by solving real-world problems

• Based within travel distance of London

• Able to commit very significant time and energy to an early-stage startup

You are NOT:

• Looking for a comfortable corporate role

• Chasing the latest crypto or fintech trend

• Someone who needs detailed instructions every day

• Interested in being employee #50

• Wanting a low time commitment role

What matters most:

Conviction.

We’ve met exceptional engineers from top universities.

What we’re looking for is someone who genuinely cares about solving this problem and wants to help build a category-defining company.

We can offer:

• Significant equity for the right person

• Direct partnership with the founder

• Massive ownership and autonomy

• Opportunity to build technology that impacts an entire industry

If you’ve built things, love emerging technologies, and want to help reinvent skilled trades with AI, we’d love to hear from you.
