Job Description
Junior Full Stack Engineer – AI Startup (TypeScript, React, Node)
Holborn, London | £35–40k | Visa sponsorship available
If you want to learn fast, ship real software, and work alongside genuinely strong engineers, this is a rare junior opportunity.
Techmunity has partnered exclusively with a fast-growing AI-first SaaS startup building an operating system used by well-known high-street coffee shops and quick-service restaurant brands.
They’re hiring Junior Full Stack Engineers to help build and scale a production system already live in hundreds of locations.
This is not a “shadow a senior and fix tickets” role. You’ll be writing real code, contributing to real systems, and learning how production software actually works.
What you’ll be working on
- Building full-stack features across a modern TypeScript stack (React, Node, NestJS)
- Developing event-driven services and real-time operational tooling
- Shipping AI-powered features used daily by store teams
- Working closely with product and senior engineers to turn requirements into robust software
- Learning modern development workflows, including testing, code reviews, pairing, and AI-assisted development
The team & environment
You’ll join a small but senior-heavy engineering team, led by an experienced Engineering Manager (ex-CTO, ex-UK Government technical lead) with 15+ years of experience building and scaling teams.
This is a high-support, high-expectation environment: you’ll be coached, but you’ll also be expected to take ownership and think like an engineer, not just follow instructions.
What they’re looking for
- Experience building web applications with TypeScript (projects, coursework, internships, or early commercial roles)
- Familiarity with React and backend concepts (Node.js / NestJS preferred)
- Solid fundamentals: APIs, Git, basic testing, data structures
- Evidence of real work: GitHub, portfolio, or shipped projects
- Comfortable working onsite in Holborn, Monday–Friday
- Curiosity about AI tools and how they’re applied in real products
Nice to have (not required)
- AWS or cloud fundamentals
- CI/CD exposure (e.g. GitHub Actions)
- Internship or junior SaaS experience
Package
- Salary up to £40,000
- Visa sponsorship available
Interviews are already underway.
