About This Job

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.
