About Wawa Fertility
17% of adults worldwide need help to have a baby and by 2050, that number will reach nearly 50%. Yet only 2% can access fertility treatment today. That’s not a gap; it’s a canyon. And we’re building the bridge.
At Wawa Fertility, we’re on a mission to make fertility care accessible to 100% of those who need it, transforming success rates and accessibility worldwide. Our end-to-end platform digitises the entire fertility journey, enabling clinics to swap spreadsheets for seamless workflows and spend less time on admin, more time on life-changing care.
We’re not tiptoeing around an industry plagued by stale incumbents and outdated tech. We’re sprinting through it. With proven product-market fit, our platform is live in 14+ countries and scaling fast. Clinics trust us. Patients rely on us. And the impact we’re making is real.
We’re building the operating system for the future of fertility care. And we’d love you to help us deliver it.
The Mission
"To make fertility care accessible to everyone who needs it because the right to start a family shouldn’t depend on where you live or what you earn."
Who You Are
You’re a builder who takes ownership. As a Series A startup, we’re highly collaborative and move fast there’s no long permission queue or unnecessary bureaucracy, just a mission-driven team working together to get meaningful things shipped.
You don’t just write code; you’re a product engineer who crafts solutions that meet and drive customer outcomes. You care about the humans on the other end of every feature the nurse checking scan results at 7am, the patient anxiously refreshing their app. Great design and snappy UX aren’t nice-to-haves for you; they’re non negotiables.
Autonomy energizes you. You set your own timelines, own your deliverables, and keep the team in the loop without being asked. You fail fast, learn faster, and never make the same mistake twice (well… almost never 😉).
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Stack & AI-forward development
Rails 8 (Hotwire, Phlex, Tailwind), React Native for mobile apps, PostgreSQL, AWS, Grafana, Sentry, and MetaBase for BI. We’re intentional about every tool we bring in.
AI is deeply embedded in how we work and over 70% of our codebase is AI-influenced. We’ve built custom skills and guardrails spanning PR reviews, design reviews, and internal documentation, all tuned to our codebase and domain. We use AI to raise the quality bar, and we’re continuously raising it.
What You’ll Do
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 across the full stack.
- 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.
