Full description
Software Engineer (Junior / Mid-Level) – AI Product Salary: £45,000 + equity
Location: Remote, anywhere in the UK (e.g. London, Manchester, Bristol, Edinburgh). There’s an optional office in Fulham, London. Stack: React, TypeScript, PostgreSQL, AI/LLM tooling
About the company
We’re working with an early-stage startup, backed by tech investors, that’s building an AI operating system for interior design and architecture studios.
Designers are great at design, but a lot of their week goes on admin. They write client proposals, chase suppliers for prices and lead times, track hundreds of items across several projects, and try to work out whether a project is making money. Our client’s platform takes that work off their hands. It brings projects, procurement, finances and invoicing into one place:
- Projects and procurement: every item, supplier and decision lives in one place, and specs and pricing come straight from supplier websites.
- Automation: clients, suppliers and contractors are updated automatically when something changes.
- Financial clarity: live margins on every project and billable hours tracked.
- AI assistant: AI agents flag risks, suggest priorities and draft communications. The designer approves everything before it goes out.
The role
This is a rare chance for a junior to mid-level engineer to join a startup as part of the founding team. You’ll work closely with their senior engineer and play a big part in shaping both the product and the company.
You’ll build AI agents, automation and new features across the full stack. They’ll trust you to take ownership: once a plan is agreed, you’ll deliver features end to end without close supervision. You’ll also work directly with customers and help on demos with prospects.
What you’ll do
- Build and ship features across the frontend and backend, using React, TypeScript and PostgreSQL
- Develop AI agents and automation that take admin work off designers
- Own features from an agreed plan through to release
- Talk to customers and prospects, including joining product demos, to understand what they need
- Use AI tools to speed up your own development
- Help shape the product, the engineering culture and how the team builds as it grows
What they’re looking for
- Full-stack experience with React, TypeScript and a SQL database (ideally PostgreSQL)
- You’ve built and shipped a real product, commercially or as a serious side project
- Comfortable on the backend as well as the frontend
- A can-do, self-starter attitude: you take ownership and get things done in a fast-moving, early-stage environment
