In this role, you will:
Drive products from 0 → 1 → 10M ARR, owning development end-to-end.
Lead feature creation, product decisions, customer conversations, and full-stack execution.
Build high-impact AI products used daily in real industrial workflows (e.g., accounts receivable automation, lead-gen automation, factory operations tools).
Collaborate directly with multibillion-dollar enterprise clients to understand pain points and design solutions.
Occasionally visit factories and warehouses to observe real users and validate workflows (infrequent but highly impactful).
This role is ideal for someone who wants meaningful ownership, fast iteration cycles, and the ability to build products with immediate real-world impact.

Software Engineer
Principal software engineer job in San Francisco, CA
As a software engineer at General Medicine, you'll help build and scale a healthcare store that makes it delightfully simple to shop for any type of care. We provide upfront cash and insurance prices for virtual and in-person visits, prescriptions, labs, imaging, and more.
What we're looking for
We're looking for strong engineers to help us build a seamless and beautiful consumer healthcare product. We're looking for folks who will obsess over every detail of our patient experience, and also tackle the complex operational challenges of delivering care at scale. We are looking for engineers who care deeply about technical excellence but are also comfortable moving quickly - we are constantly navigating tradeoffs between engineering velocity and quality.
Our ideal candidate is hungry, high-agency, and aspires to be a generalist. Our engineers frequently write product requirements documents, write SQL to understand how features are performing, and own QA - no task is beneath us or outside of the scope of the role if it helps us to deliver a great product. We're looking for someone who can operate in an environment of significant ambiguity, and who is comfortable working closely with design, operations, and clinical stakeholders.
We don't expect you to have a healthcare background (though it's great if you do!). However, you should be excited by the prospect of digging into the messy complexities of the American healthcare system (integrating with EHRs, revenue cycle management, etc).
Qualifications
2+ years of experience building web apps as a full-stack engineer
Experience with modern infra tooling and programming languages. We currently use AWS, Ruby on Rails, and NextJS, and would expect you to have proficiency in a modern tech stack even if it isn't the one we are using.
Please note that this role is based in either our SF office (near Market and Spear St) or our Boston office (Central Square, Cambridge). We expect our team to work from the office least 3 days per week.
Why join us
We're an experienced team that has built a company in this space before, our product has clear product-market fit, and we've raised money from top investors.
We have an ambitious and distinctive vision for what can be built in consumer healthcare. We believe LLMs and price transparency legislation have opened up several massive opportunities.
If you're an ambitious and entrepreneurial software engineer and this resonates, please apply.
