Job description

Описание

Fresha is the leading AI-powered operating system for the global beauty and wellness industry, giving businesses everything they need to run smarter, grow faster and build stronger client relationships. Our mission is simple: help beauty and wellness businesses grow by giving them the technology they need to attract clients, manage their operations and run their business in one place.

Задачи

• Own features end to end: Design it, build it, test it, ship it, and look after it once it’s live.
• 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 both.

Требования

• Experience: 5+ years building and running backend services in production.
• 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 built and run services at scale, and you know how they fail.
• Event-driven architecture: You’ve designed systems around asynchronous events, not just request and response.
• Kafka 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.
• Languages: Strong in at least one backend language. We don’t expect Ruby or Elixir on day one, but we do expect you to pick things up fast.
• 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: Frontend or native mobile experience is a bonus rather than a requirement, but we do expect engineers to pick up what a piece of work needs.
• Будет плюсом: Frontend or native mobile experience is a bonus rather than a requirement

Условия

• B2B 25–40 k PLN net / month + ESOPs
• Scale: Around 1 million bookings a day across 120 countries, and the payments that go with them, running on a platform we’re breaking out of its monoliths while it serves traffic.
• Speed: We release daily, 500+ deploys a day, with not much standing between your branch and your users.
• Ownership: The tooling, data and permissions to run what you build, and a say in the technical direction of your area.
• Room to broaden: When you move into the frontend or mobile side, you get the time and support to learn it rather than being thrown at it.
