Job Specifications

London • £90k • Start‑Up Culture • Greenfield • Product‑Led Tech Company

I am recruiting for a fast‑growing tech scale‑up that’s transforming how hospitality and retail businesses manage flexible staffing. They are a proper product‑driven technology company building a platform that connects businesses with high‑quality staff.

You’ll be joining one of three cross‑functional engineering squads, each owning its own roadmap and delivering new greenfield features across mobile, backend services, and internal tools. It’s a place where engineers have real influence, ship fast, and work closely with product and design to solve meaningful operational challenges at scale.

What You’ll Work On

Building clean, high‑performance mobile experiences using Flutter (or another modern frontend framework if you prefer — they're flexible).
Designing and delivering Go microservices powering the platform’s real‑time matching, scheduling, payments, and operational logic.
Working on our Python monolith, incrementally migrating functionality into services when it makes sense.
Contributing to a modern, cloud‑native stack built on AWS, Terraform, PostgreSQL, and GraphQL.
Owning new product features end‑to‑end - from design and architecture through to production rollout.

Who Theyr’re Looking For

You might be frontend‑leaning with Flutter, or backend‑leaning with Go/Python - either direction works. What matters is that you’re the kind of engineer who thrives in an environment where you can experiment, shape solutions, and build things the right way.

You’ll fit well if you enjoy:

Working in a collaborative squad alongside product, design, and data.
Solving complex problems with simple, elegant solutions.
Building high‑quality software in a high‑trust engineering culture.
Contributing to greenfield product development in a company that values autonomy, ownership, and velocity.

£90k salary
On‑site in London with a tight‑knit, high‑energy team
Start‑up culture with genuine ownership
Opportunity to work across mobile, backend, and platform
Build meaningful, impactful features used in the real world every day
Join a tech organisation that actually behaves like one — engineering‑led, product‑focused, and innovation‑driven
