Solutions Engineer - API Platform

Staff Solutions Engineer - API Platform

Our healthcare system remains frustratingly analog. When you live in a world of one-tap car rides, instant meal delivery, and unlimited streaming, why do you still have to call to schedule a doctor's appointment and fill out a clipboard in the waiting room?

Nex Health's mission is to accelerate innovation in healthcare by connecting patients, providers, and developers. We're building the infrastructure layer for modern healthcare, connecting thousands of fragmented, on-premise, and closed EHR systems into a single, modern platform that powers software, APIs, payments, and patient experiences across the ecosystem.

The Synchronizer API is the strategic core of Nex Health. The SaaS product was the wedge that gave us deep integration with thousands of practice management systems – the API is what we built that wedge for, and it's where the next decade of the company gets built.

This role exists to scale that. You'll be the founding senior Solutions Engineer on the API team – the technical anchor on our most important enterprise opportunities and the person who makes it possible to land them.

In this role, you will:

• Anchor our most strategic enterprise opportunities: partnering with Enterprise Sales across discovery, scoping, technical design, and implementation on the deals that matter most.
• Own complex integrations end-to-end: from first technical conversation through production launch, including the implementation phase where the hardest technical work happens.
• Accelerate growth in our highest-potential API customers: deepening technical partnership with the customers building the most ambitious products on top of our platform.

You'll work directly with senior leadership across Product, Engineering, and Go-to-Market – and you'll set the bar for the API Solutions function we'll build around you.

• Own the technical relationship on flagship deals. Run pre-sales discovery, scope Statements of Work, design integration architectures, and stay attached through implementation.
• Translate customer workflows into reliable system designs. Map real-world workflows into data flows, endpoints, webhook patterns, retries, and ordering across heterogeneous EHR/PMS systems. Find the edge cases before they find production.
• Be the SME on the Synchronizer API. Advise customers on architecture, data modeling, integration patterns, reliability, and performance – the kind of guidance that comes from actually understanding what's underneath the API.
• Build the artifacts that scale you. Reference architectures, prototype apps, sample code, integration guides, demo environments. Anything that compresses a customer's time-to-value or removes you from the next conversation that doesn't need you.
• Close the loop with Product and Engineering. Bring back signal, not noise, on what's blocking enterprise adoption, what should ship next, and where the docs are lying. You'll have a direct line to the people who can fix it.

• Project ownership, not ticket-taking. You run cross-functional programs end-to-end. SOWs, pilots, escalations – you drive them.
• First-principles debugging. You go deep on ambiguous issues, design novel solutions, and don't hide behind "the docs say."
• Executive-grade communication. Same person, different audiences: a CTO on Tuesday, their senior engineer on Wednesday, our COO on Thursday. All three walk away clearer than when you started.
• Builder mindset. You'd rather ship a working prototype than write a deck about one. You leave behind tools, templates, and patterns that make the next person faster.

• 7+ years in Solutions Engineering, Technical Account Management, Developer Relations, or a similar customer-facing technical role at a SaaS or API-first company.
• Hands-on fluency with REST APIs, JSON, OAuth2, and webhooks. You're comfortable in logs, in someone else's codebase, and on a shared screen with a customer's engineer.
• A track record of owning complex, multi-month enterprise integrations end-to-end – not just the kickoff call.
• Demonstrated ability to translate between executives, engineers, and operators without losing precision.
