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.
  • The backend systems you architect will power how this next wave of patients discovers treatments, qualifies for care, and receives highly personalized, dynamic dosing protocols.

Responsibilities

  • Build Clinical State Machines: Own the systems that power complex medication ordering and fulfillment.
  • You will build highly reliable pipelines that handle compounding pharmacy integrations, controlled substance compliance, and personalized dosing protocols across a distributed network of external partners.
  • Own the Infrastructure: Take hands-on ownership of the AWS and Kubernetes infrastructure that runs your services. You will establish CI/CD pipelines, build observability, and create deployment patterns that make it safe for the entire team to ship rapidly.
  • Act as a Product Partner: Work directly with Clinical, Operations, and Product teams to shape what we build.
  • You will evaluate proposed workflows, take ownership of business outcomes, and actively identify paths to deliver maximum patient value with highly efficient implementation.
  • Build Agentic Workflows: Mochi is an AI-first engineering org.
  • You will not only utilize frontier agentic models to accelerate your own development, but you will also design the backend architecture that allows AI-assisted agents to automate clinical operations, improve patient safety, and scale our provider workflows.
  • Raise the Engineering Bar: Own key architectural decisions, systematically upgrade legacy systems, and elevate the engineers around you through rigorous code review, testing practices, and technical standards.
  • 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.
  • At Mochi, we believe your best work happens when you feel your best-so we've designed an environment that fuels your creativity, supports your growth, and makes every day exciting.

Requirements

  • You have operated high-stakes systems.
  • You have 5-7+ years of backend engineering experience.
  • You are an infrastructure owner.
  • You can describe specific ways these models have structurally changed how you code, while retaining the deep technical skepticism required to audit, verify, and own its output.
  • You are a collaborative builder.
  • You have low ego, high standards, and excellent communication skills.
  • You are excited to work in-person.
  • 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.

Nice to have

  • We expect a demonstrated track record of setting technical direction across teams, navigating deep ambiguity, and measurably leveling up the engineers around you.

  • Experience with these is a strong plus, but we index on engineering fundamentals, distributed systems experience, and domain reasoning over language-specific syntax.
  • We respect your time.
