About Onboard AI

Onboard AI is building the trusted foundation for responsible AI in healthcare. Our platform empowers hospitals, payers, and AI developers to confidently adopt AI by simplifying everything from evaluation and procurement to deployment and ongoing oversight. We make it easy for teams to navigate privacy, security, patient safety, fairness, and regulatory requirements through structured workflows and evidence-driven governance.

We’re backed by leading investors, generating revenue, and already working with some of the world’s most respected healthcare organizations. Join us as we shape the future of responsible AI adoption in healthcare.

The Role

We are seeking a Lead Software Engineer to take ownership of our core product experience. You will shape, build, and ship the Onboard AI web platform end-to-end—from concept through deployment—working closely with users, product leadership, and company founders.
You’ll be highly hands-on: identifying customer needs, designing elegant solutions, writing code, and shipping fast and reporting directly to the CEO - a multitime healthtech founder. As our first senior engineering hire, you will play a critical role in defining engineering culture, velocity, and best practices working alongside the AI team with engineers and PhDs from Stanford and Harvard.

What You’ll Do

Participate in full lifecycle product development—from customer insight to production deployment
Lead architecture and implementation of new features and platform capabilities
Collaborate directly with users to translate feedback into intuitive, scalable solutions
Establish and uphold software engineering best practices, code quality, and testing standards
Partner with product leadership to define roadmap and align technical impact with business value
Leverage AI-assisted development tools to amplify productivity and maintain high velocity
Exercise unbounded curiosity about the ‘why’ before building anything

Core Requirements

Deep Ruby on Rails experience (> 5yrs seems like a good floor). We make heavy use of Hotwire and Turbo, so that’s required experience as well. The ideal candidate is excited about this: Rails has gotten wonderful again.
This is a full stack role, meaning you’ll be responsible for making the frontend look nice as well as the backend. We use Tailwind with ViewComponents.
Product minded. Or maybe even product-obsessed. We’re a small team, and as the lead engineer, you’ll give life to our product. You’ll talk to customers and transform their problems, feedback, and questions into delightful features.
We’re deployed to Heroku, so you should be experienced in the care and feeding of a Heroku application.
You should come in with some strong opinions on how to leverage AI coding tools. The ideal candidate keeps up to date with both the capabilities of the tools as well as how to best use them. (Have you been debating whether to replace your MCPs with skills? That’s that type of candidate we’re looking for.)
On the topic of LLMs, you should also have experience in building AI into your apps. We leverage both Anthropic and Claude APIs within our product. We’re looking for someone who has used evals to tune prompts for reliability and predictably delivering high quality outputs.
Comfort working in a fast-moving startup environment with high autonomy
Comfort traveling to customer on-sites, team meetings, etc.

Nice to Haves

Experience building software for regulated environments (SOC 2, HIPAA, hospital infosec requirements, etc.) and managing enterprise requirements, like SSO
Experience working in healthcare, ideally at a startup
Ability to quickly prototype low-cost proof-of-concepts while maintaining long-term technical integrity
