The roleYou'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 firstPulse — 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 workWe've stopped writing code by hand — we specify, evaluate, and debug.
