Who You Are
You’re the kind of engineer who sees a tangled codebase and thinks “I can fix that” – not “that’s not my problem.” You thrive when the stakes are high, the pace is quick, and the work genuinely matters. You don’t just write code; you craft solutions and care about the humans on the other end of every feature – from nurses to patients. Autonomy energises you; you set your own timelines, own deliverables, and keep the team informed without being asked.
What You’ll Do
- Build and ship features end-to-end in a modern Rails 8 stack with Hotwire, Phlex, and Tailwind.
- Solve genuinely complex problems daily – healthcare data, real‑time scheduling, multi‑country compliance.
- Collaborate with designers and clinicians to deliver interfaces that are fast, intuitive, and beautiful.
- Take ownership of your domain: you’re not waiting for a ticket – you’re spotting the opportunity and running with it.
- Shape the architecture and engineering culture of a product used by clinics across 14+ countries.
What You Bring
- A deep appreciation of the Rails Way, with the chops to build elegant, scalable solutions.
- Experience shipping production features in Ruby on Rails (bonus points for Hotwire / Turbo / Stimulus).
- Transparent and intellectually honest communication – you say what you mean and mean what you say.
- A hunger for high‑tempo environments where speed and quality are balanced through individual responsibility.
- An eye for great design and a drive to create experiences as beautiful as they are functional.
- A willingness to fail fast and learn faster – two‑way doors are your favourite kind of doors.
What We Offer
- Mission‑Driven Work – help solve the global fertility crisis. Every feature you ship makes care more accessible for families worldwide.
- Generous Rewards – a significant share in the company’s success. Your contributions are reflected in real equity and real upside.
- Ownership & Impact – no red tape, no waiting for permission. You’ll define, build, and ship – with direct impact on the product and the mission.
- Growth & Learning – develop professionally while shaping the future of healthcare technology. Wear many hats and level up fast.
- Early Team Magic – join the founding crew. Help set the standards, culture, and direction of the company for years to come.
- Hybrid & Flexible – 3 days a week at our Paddington office with flexibility built in. We trust you to do great work wherever you are.
We are an equal‑opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all team members.
