About the Job

Requirements

Five to seven years of experience building and running production web applications.
Strong Python and SQL skills, including owning a schema, writing migrations, and reasoning about query costs.
Ability to build usable full-stack interfaces.
Understanding of why multi-tenant isolation belongs in the database, not only in a WHERE clause.
Ability to write behavior-descriptive tests and provide specific code reviews.
Ability to work effectively in a small engineering team and ship work used by pharmacy staff.
Healthcare experience is not required; experience with protected health information, HIPAA, business associate agreements, HL7, FHIR, pharmacy or infusion workflows, claims, immunization registries, or EHR integration is advantageous.

Responsibilities

Build and run production web applications, including maintaining live systems used by customers.
Improve the existing software used by home-infusion pharmacies and develop it into a product for other pharmacies.
Build software supporting ordering, referral intake, clinical workflows, and delivery.
Develop and maintain backend services using Python, FastAPI, and SQLAlchemy 2.
Develop and maintain frontend applications using TypeScript, Next.js, and React.
Work with PostgreSQL and GCP.
Use Claude and Gemini in the AI stack.
Write tests using pytest and Playwright, with coverage gates; use ruff and mypy.
Deliver software used in pharmacy workflows and collaborate with the pharmacy team on site.

Desired Qualifications

Healthcare or pharmacy experience, particularly experience with protected health information, HIPAA, business associate agreements, HL7, FHIR, pharmacy or infusion workflows, claims, immunization registries, or EHR integration.

Full-stack engineer

We build the software a home-infusion pharmacy runs on — ordering, referral intake, clinical workflow, delivery. Real hospitals use it today. We're looking for the engineer who takes it from one pharmacy group to a product other pharmacies buy.

Role: Full-stack engineer (individual contributor)
Location: Stockton, CA — on site
Type: Full-time
Experience: 5–7 years
Start: As soon as you can
Domain: Healthcare / pharmacy — a major advantage, not a requirement

The stack

Backend: Python · FastAPI · SQLAlchemy 2 · PostgreSQL
Frontend: TypeScript · Next.js · React
Cloud: GCP
AI: Claude and Gemini
Testing: pytest with coverage gates · Playwright · ruff · mypy

What we're looking for

5–7 years building and running production web applications — not just writing them, but keeping them up.
Strong Python and strong SQL. You're comfortable owning a schema, writing the migration, and reasoning about what a query costs.
Genuinely full-stack: you can build the interface people actually use, and you care whether it's any good.
You understand why multi-tenant isolation belongs in the database and not only in a WHERE clause.
You write tests that describe behaviour, and you're specific in review — about your own work as much as anyone else's.
You're comfortable being one of a few engineers, where the thing you finish this week is in front of a nurse next week.

Healthcare experience is a major advantage

Not a requirement, and we'll teach the domain to the right engineer. But if you've worked with PHI before — HIPAA in practice, business associate agreements, HL7 or FHIR, pharmacy or infusion workflow, claims, immunization registries, EHR integration — you'll start months ahead, and it will show in what we offer you.

What matters most is the instinct that comes with it: knowing which mistakes are recoverable and which ones involve a patient.

What this role is not

Not a management track. We want a builder, and the job stays hands-on.
Not greenfield. Real systems are live with real customers; you'll be improving software people already depend on, with the care that requires.
Not remote. This is on site in Stockton, with the pharmacy team you're building for down the hall — which is most of why the software fits how they actually work.
