# Software Engineer, Applied AI

Lassie

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
We're hiring an engineer to build the AI agents that run doctor's offices.
These are production systems handling real money and real patient data for thousands of practices. You'll work across the full stack: agent architectures, data pipelines, evals, and the infrastructure that makes it all reliable.
YOU WILL BE A GREAT FIT IF YOU…
• Are excited to work with frontier models
• Engineer for reliability and correctness, not just functionality
• Diagnose and resolve live production incidents with minimal disruption
• Automate away repetitive work and build tooling that makes engineering faster and safer
• Design schemas and pipelines for large-scale datasets to power applied AI
• Are comfortable working across databases, caches, proxies, and job orchestration 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 http://blog.superhuman.com/superhuman-is-built-for-speed 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.
