Senior Frontend Engineer

The role

You're building the face that makes "AI colleague" feel real — this is where everyone judges the rest of our work.

If Holmes feels like a chatbot instead of a colleague, nothing else matters. Clinicians will leave.

What you'll build first

Pulse — the communication layer of our Autonomous Health System.

Behind the interface, agents and clinicians operate on the same platform: same permissions, same context, same accountability. Pulse is where that becomes visible.

The goal isn't "Slack for healthcare." It's that messaging Holmes feels exactly like messaging a human colleague. No seams. No "AI mode." Real-time, HIPAA-compliant, deviceless. Complex data visualized at a glance. Micro-animations that make the difference between "broken" and "inevitable."

How we work

We've stopped writing code by hand — we specify, evaluate, and debug. When AI generates something wrong, we fix the spec that let it happen. You'll work embedded with product and design in empowered teams. Shared ownership. No handoffs.

You're a fit if you have

• 7+ years building production frontend applications people actually use

• Watched real users struggle with your mistakes — and it changed how you build

• Deep experience with data visualization and complex interactive interfaces

• Obsession with details that separate broken from inevitable

• Strong opinions on performance, accessibility, micro-interactions

Also great if you have

• Healthcare or regulated industry experience

• Real-time collaborative interfaces (chat, multiplayer, live dashboards)

• A design sensibility — you've argued with designers and sometimes were right
