About the role

At Mochi, our engineering team operates with exceptional leverage. We believe in high talent density, where a focused, elite team powers a profitable, nine-figure ARR healthcare platform serving hundreds of thousands of patients. We are looking for a Senior Backend Engineer to own the core systems that power this scale—from clinical approval workflows and multi-pharmacy fulfillment routing, to complex subscription billing and partner integrations.

What they're looking for

  • You get data modeling right. You think carefully about schema design, state transitions, and domain boundaries, because you've seen what happens downstream when the foundational model is wrong
  • You are excited to work in-person. You want to build alongside the team 5 days a week in our San Francisco office
  • If you are targeting Staff leveling: We expect a demonstrated track record of setting technical direction across teams, navigating deep ambiguity, and measurably leveling up the engineers around you
More about this role

Healthcare is broken at the first step: patients can't find the right care, understand what it costs, or access the medications they need. Mochi Health is fixing this.

We're building an AI-driven marketplace that makes healthcare discoverable—connecting patients to the right providers, transparent pharmacy pricing, and affordable medications. Over the past few years, we've grown rapidly by combining clinical expertise with technology that actually works for real people, not just hospital systems.

Our platform does what legacy healthcare can't: it gives patients transparent pricing before they pay, personalized medication management that follows them across providers, and long-term access to their own medical records. We're proving that healthcare can be more affordable, more human, and far more intuitive than what exists today.

Join a team that's rebuilding healthcare from the patient up. At Mochi Health, you'll work alongside people who value bold thinking, inclusive collaboration, and getting meaningful work into the world. If you want to do the most impactful work of your career, this is where to do it.

$230,000 - $280,000 (Open to Staff leveling at $280-330K)
