Junior Full Stack Engineer – AI Startup (TypeScript, React, Node)

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
• 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

Interviews are already underway.
