Job description

We're the world's leading consumer healthcare platform, supporting millions of patients across the US, Australia, the UK, Germany, Japan, Spain and Canada.

We're driven by the belief that good health should last a lifetime, and that to get there we need to deliver the personalised, high quality and empathetic care that the traditional system cannot support.

You'll partner with our care teams of prescribers, nurses, health coaches, pharmacists and dietitians to support patients across preventative health, weight management and specific women's and men's health conditions.

We joined Hims & Hers so that you can do all of the above on a bigger scale, with more ambition, a stronger global brand and the resources to deliver care to patients in dozens of countries.

We're looking for people who appreciate and are excited by the enormity and uniqueness of this challenge, and want to work in the most ambitious, smart, fast moving and positive sum environment of their lives to transform how healthcare is delivered globally.

We hope that's you.

Own our Frontend Web, run growth experiments, and shape product impact

At Eucalyptus, we’re on a mission to make healthcare simpler, safer, and more accessible. Patients face friction when navigating care, and the Growth squad focuses on building frontend web experiences that directly move key metrics—retention, engagement, and conversions—while shaping the overall patient experience.

One of the key initiatives you’ll contribute to is experimentation across the frontend platform, designing and testing features that influence how patients engage with our services. This is a chance to drive measurable impact and shape best practices for the platform used across the business.

Our stack: React, React Native, GraphQL Federation, Go, TypeScript, gRPC, Pub/Sub, Kubernetes, GCP.

The impact you will have

  • Take ownership of the frontend web platform, ensuring scalable, polished, high-performance experiences

  • Design and deliver growth-focused experiments that improve retention, engagement, and conversions

  • Collaborate closely with product and marketing to translate insights into actionable features

  • Influence frontend best practices across the team and mentor teammates

Who succeeds here

You’ll likely succeed if you:

  • Have strong React & TypeScript experience, with full ownership of web products

  • Are experienced working on frontend platforms or product-facing web apps

  • Have a commercial mindset, understanding how features and experiments impact business metrics

  • Thrive in autonomous, senior-level roles, able to take ownership end-to-end

You don’t need to tick every box — if this role excites you, we’d still love to hear from you.

Nice to haves

  • Growth-focused engineering experience

  • Experience with GraphQL

This is a senior, high-autonomy role where engineers get to own the frontend experience, define best practices, and directly influence growth metrics. You’ll work in a team that values experimentation, collaboration, and measurable impact, shaping features that truly move the needle for patients and the business.

If driving growth through product engineering and shaping high-impact patient experiences sounds exciting, we’d love to hear from you.

At Eucalyptus, we value individuals from all backgrounds, experiences, and perspectives, and we embrace the unique qualities each person brings. When you apply, please let us know of any reasonable adjustments you may need during the interview process. We use AI-assisted tools across our business to help our teams work more efficiently, including within our recruitment process. These tools support our team — all hiring decisions are made by real people, and every application is reviewed by a member of our recruitment team.
