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.

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. We’re collaborative without the bureaucracy. There’s no long permission queue, just a mission-driven team working together to get meaningful things shipped. You craft trustworthy systems. You care about the humans at the end of every pipeline: the nurse checking scan results at 7am, the clinic lead staring at a dashboard, the patient whose record has to be exactly right. Clean, reliable, well-modelled data is non-negotiable for you. You’ll be working inside a small team of data folks. Autonomy is important, but collaboration is a priority.

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, and the data layer underneath it is the nervous system. From embryology records and follicle scans to payments and outcomes, you’ll turn messy, high-stakes clinical data into a clean, trusted foundation the whole product runs on.
• Design and ship data pipelines end-to-end: ingesting from EMR and clinic source systems, modelling into a canonical data layer, and serving analytics-ready datasets and insights.
• Work closely with customers to migrate and validate data from their old EMR to wawa. Managing customers through complex data migrations step-by-step to ensure they have the best start with Wawa.
• Solve genuinely complex problems daily: heterogeneous healthcare data, schema mapping across clinics, data quality and validation, and multi-country compliance.
• Collaborate with application engineers and clinicians to deliver datasets and metrics that are accurate, well-documented, and genuinely useful.
• Shape the data architecture and engineering culture of a platform used by clinics across 14+ countries and scaling fast.

What You Bring

• A deep appreciation of well-modelled data, with the chops to build elegant, scalable pipelines and a sensible warehouse.
• Experience working with clinical healthcare datasets and standards (OMOP is a plus).
• Experience building production data pipelines with strong SQL and Python (bonus points for AWS and Ruby).
• Comfortable working directly with clinics and external stakeholders.
• Transparent and honest communication.
• A collaborative, respectful, and positive presence on the team.
• An eye for data quality and a drive to build pipelines that are reliable and observable.

What We Offer

• Mission-Driven Work: Help solve the global fertility crisis. Every feature you ship helps make care more accessible for families worldwide.
• Generous Rewards: Share in the company’s success. Your contributions are reflected in meaningful equity and real upside.
