Role
Who you are
- Experience: 5+ years building and running product software in production
- Depth on one side, competence on the other: You're strong in either the frontend or the backend and you can hold your own in the other. Tell us which way round you are. We are not looking for someone who is shallow in both
- Frontend: Commercial experience with React and TypeScript, and with building interfaces that hold up. Comfortable with CSS, including animation, and with the usual JavaScript build tooling
- Backend: You've built and run services in production. We don't expect Ruby or Elixir on day one, but we do expect you to pick things up fast
- APIs: You've designed and consumed GraphQL APIs, and you think about the people on the other end of them
- Correctness: You think about what happens when a request arrives twice, a downstream call times out halfway through, or two things update the same record at once. You design for it rather than finding out later
- Distributed systems: You've worked with services that talk to each other over events and RPC, and you know how they fail. Kafka, gRPC or equivalent
- Comfortable close to production: You're at ease shipping behind flags and watching a change land. You know what to instrument before a rollout and what to watch afterwards
- AI in your workflow: You use AI coding tools day to day and have a clear view of where they help and where they don't. You're happy building your own workflow rather than waiting for one, and you review what comes back before it ships
- Pragmatic: You care about the right tool for the job more than any particular stack, and you've worked in more than one style of language
- Curious: You like getting deep into a domain, and you're willing to get into the weeds
- Willing to broaden: Native mobile experience is a bonus rather than a requirement, but we do expect engineers to pick up what a piece of work needs
- At Fresha, we value passion and potential as much as specific skills. If you're enthusiastic and eager to learn, we encourage you to apply, even if you don't meet every listed requirement
What the job involves
- You'll join a cross-functional product team and report to its Team Lead
- Full stack here means you own a feature the whole way down: the React and TypeScript screens people use, the GraphQL layer in between, and the services behind it. Most engineers arrive stronger on one side than the other. That's expected, and we hire for it openly
- We work on a short feedback loop. Your change usually reaches production the same day you write it, behind a feature flag. The team that builds a service looks after it, including a shared on-call rota
- We're also changing how engineering gets done here. Every engineer gets Claude, Codex or Cursor from day one, and people build their own agent workflows rather than being handed one
- It isn't finished, and you'd be helping to shape it rather than inheriting it. We look for engineers who know how to break work up, how to review what comes back, and how to stand behind the result
- Own features end to end: Design it, build it, test it, ship it, and look after it once it's live
- Build the UI: Implement new functionality and interfaces in our web frontend, against a custom design system, and in the native apps when a piece of work reaches them
- Design and document APIs: GraphQL and gRPC APIs that your own team and other teams will build on, built to be used by people who won't ask you first
- Ship most days: Your change goes out behind a feature flag, usually the same day you write it. CI/CD handles the rollout. You watch the dashboards and roll back if it looks wrong
- Work across services: Most features touch more than one repo. You'll plan and ship changes across several services at once
- Work with the rest of the team: Product, Design, Frontend, Infrastructure and Mobile, from the first conversation through to release
- Keep things healthy: Find the bottlenecks, fix the bugs, and keep an eye on performance and quality
- Have a say in how we build: Our architecture and our engineering practices aren't fixed. We expect senior engineers to push on bot
- Our stack: the web frontend is React and TypeScript on a custom design system, talking to the backend through a federated GraphQL layer. Services are written in Ruby, Elixir and TypeScript, with Kafka for events, gRPC or JSON for synchronous calls, Postgres, and everything running in Kubernetes
- Domain-driven design is at the heart of how we work: we build fast, but we think about the bounded context first. We're partway through breaking our Ruby/Elixir monoliths into services. Our mobile apps are native, Swift on iOS and Kotlin on Android, and the APIs you write serve them too. You don't need Swift or Kotlin on day one, but you will work across them as the work requires

Our take
Fresha allows consumers to discover, book and pay for beauty and wellness appointments with local businesses via its centralised marketplace, while beauty and wellness businesses and professionals use its all-in-one platform to manage their entire operations through a range of intuitive software and fintech solutions.
The company has taken a different approach compared to rivals in the salon management space. Rather than charging monthly, its software is free to use, and charges only when a booking is made through the system. Fresha's platform also offers a range of financial products such as point-of-sale, customer records management and marketing automation, making it an appealing option for salon operators. This has allowed the company to swiftly build a network of merchants for its marketplace and collate over 110,000 partner businesses processing over 1 billion appointments booked to date. The marketplace also creates revenue potential for partner companies through its online bookings, building integrations with social media brands like Instagram and Facebook.
Now that Fresha has solved the chicken-and-egg problem of starting a marketplace, it is using its market position to scale quickly. It now has 130,000 partner venues and is working in 120 countries. Between 2021 and 2023, it enjoyed 190% growth in its global bookings.
