Job description

the company | Senior Software Engineer (Founding Team) | ONSITE: Houston, TX (Sugar Land) | Full-time | $100k–$140k + Founding Equity, adjustable

Clinical software is where a provider's time goes to die. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.

Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and are underserved by the tech sector. We're building a foundation designed to eventually scale across thousands of providers and multiple medical specialties.

You’ll join as a founding engineer working directly with myself (Xoogler SWE) and my co-founder (one of the US's best known O&P clinicians), and a new engineer. You will own massive surfaces end-to-end, making the foundational architectural decisions for our entire platform. We have clinics using our suite and already saving hours a day, but we've got a massive pipeline ahead and need your help to build it. And we participate in humanitarian missions to expand prosthetic access in critical parts of the world like Ukraine.

• The Stack: C#/.NET, contract-first gRPC, SolidJS/TypeScript, and PostgreSQL, built with strict domain-driven design and rigorous testing.
• How we work: We have total flexibility on your workflow. Love AI-assisted speed coding? Go for it. Prefer to write by hand because your mental model is faster than prompting? Perfect. We only care about delivering safely and quickly.
• Requirements: Senior-level depth with production systems, a strong habit of domain modeling, and a philosophy that defaults to simplicity. Strong UI/UX experience with an obsession for user simplicity is a must.

To apply, email me directly at [e-mail] with a short story about a favorite technical challenge you solved end-to-end. Please put "HN" in the subject line!
