Software Engineer, Platform

Department: Engineering

Location: San Francisco, CA

Employment Type: FullTime

Our mission is to help small businesses run themselves. We’re starting with doctors’ offices, building autonomous systems that handle busywork and complete the workflows that keep the office moving every day. Our team is small, flat, and ambitious. We value craft, intellectual rigor, and direct communication.

About the role

Platform engineers build the systems that let Lassie’s agents do real work reliably: integrations, orchestration, data infrastructure, observability, and the foundations behind every new workflow we launch.

What you'll do

• Build the integrations, data models, orchestration, and reliability systems that let Lassie’s agents complete real workflows at scale

• Create internal tools, observability, and infrastructure that help the team launch new workflows faster and with more confidence

• Work closely with product and operations to turn messy real-world processes into dependable systems

Some things we've built

• Data pipelines processing $1B+ in insurance claims

• Systems that eliminate thousands of hours of paperwork every month

• A sync engine backed by encrypted SQLite in the browser, enabling 100ms experiences for healthcare payments and patient ledgers

Technology we use

We invest heavily in productivity. Engineers should have the best tools for the job and the freedom to choose them.

• Python (Django, Pydantic AI), Postgres, Redis

• TypeScript, React, Tailwind

• Google Cloud Platform, Vercel

• Linear, Slack, Notion

Joining us

To start, you'll have a handful of conversations with our team and founders. If there is mutual excitement, we'll invite you to the office where you'll work on a small project and meet the team.
