The Role

This is a role for builders who want to make a direct impact. We’re creating a complete operating system for fertility clinics - from managing follicle scans to processing payments. It’s a rare chance to reinvent healthcare workflows for an entire sector.

  • 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.
  • Generous Rewards - A significant share in the company’s success.
  • Ownership & Impact - No red tape, no waiting for permission.
  • Growth & Learning - Develop professionally while shaping the future of healthcare technology.
  • Early Team Magic - Join the founding crew.
  • Hybrid & Flexible - 3 days a week at our Paddington office.
