Founding Frontend Engineer/Lead Mission-Driven HealthTech / Wellness Startup (Transforming Cancer Care)

San Francisco Bay Area (1-2 days a week in-person out of SF)

Must have early-stage experience (0 1 or early scale)

Build with Purpose. Ship with Impact.


Cancer is overwhelming - not just the diagnosis, but every step that follows. Patients and families face a fragmented, impersonal system that too often fails them. We're building something better.


This is a rare opportunity to own the frontend for a product that's already changing lives, at a company with 20x month-over-month revenue growth, top-tier backers (Pear VC led our last round), and a founder with deep founder-market fit (ex-Flatiron, former caregiver, and product leader in oncology).


If you're a senior frontend engineer or EM-level builder craving full ownership and real-world impact - this is the one.


The Role

As our Founding Frontend Engineer/Lead, you'll lead all things UI/UX and frontend architecture. You'll shape the product experience for patients, caregivers, and clinicians navigating serious illness - from system design to pixel-perfect implementation. You'll collaborate closely with product and design to bring empathy, precision, and performance into every interaction.

This isn't just a "build what's spec'd" role - you'll be a critical thought partner in product decisions, and your code will directly affect how people experience care.


What You'll Own

  • Full ownership of the frontend - React, TypeScript, design system, testing, and perf
  • Translate complex care workflows into intuitive UI with real-world constraints
  • Collaborate tightly with product, design, and backend to deliver thoughtful UX
  • Set the bar for quality, performance, and accessibility
  • Shape how we scale: systems, processes, and future hires

You Might Be a Fit If

  • You've built and shipped products at the seed or Series A stage (ideally 0 1)
  • You thrive on high ownership and low red tape - a true product collaborator
  • You're a frontend craftsperson: React + TS are your bread and butter
  • You sweat details, think in systems, and care deeply about user experience
  • You're local to SF and energized by being in the room with people building fast
  • You're mission-aligned - maybe even personally connected to the problem

Bonus: You've built design systems, led perf/debug initiatives, or contributed to accessibility best practices.


Why Now?

  • Real momentum: 20x MoM revenue growth. Product already used by top 20 pharma and major care providers.
  • Clear problem, urgent need: Everyone has a cancer story. We're fixing the experience behind the scenes.
  • Founder's got it: Rare mix of personal story, deep domain knowledge, and product chops.
  • Sharp team: Backed by Pear VC and top healthcare angels. Product-minded, founder-led, and deeply driven.

If you're an engineer who wants to build with empathy, lead with conviction, and scale something that matters - let's talk.


Drop a note or apply confidentially. We'd love to meet you.
