Software Engineer

About NexHealth 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? NexHealth’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. Founded: 2017 Headquarters: San Francisco, CA Funding: $177M Series C Employees: 200+ Trusted by tens of thousands of providers and hundreds of health-tech developers — forging the infrastructure layer that modern healthcare needs About the Role This is a rare chance to get in early on a company redefining what healthcare infrastructure looks like. As a Software Engineer I at NexHealth, you'll work on meaningful, real-world problems from day one - not toy features, not endless ticket queues. You'll write production code that touches the lives of patients and providers across tens of thousands of practices. We're looking for engineers who are early in their careers but sharp, curious, and ready to grow fast. You'll be embedded in a small, senior team, which means a high learning curve, real ownership, accelerated mentorship and direct exposure to the kind of systems design and architectural thinking that usually takes years to encounter elsewhere. This role focuses primarily on back-end development, contributing to our core platform - no-permission integrations with the EHRs, high throughput data ingestion pipelines, scaled storage and low latency data serving that connect healthcare's fragmented ecosystem. You don't need to have done this before at scale; you just need the fundamentals, the drive to figure it out and learn from the best. What You'll Do Build and ship features across NexHealth's core platform, including our healthcare integration API and provider-facing SaaS product, with guidance from senior engineers. Write clean, well-tested, production-ready code - and learn what that actually means in a fast-moving, high-stakes environment. Participate in code reviews, technical discussions, and architecture conversations - we want your questions and your perspective from the start. Debug and investigate issues in distributed systems, developing the pattern recognition that comes from working on real infrastructure. Contribute to indirect integrations with electronic health record (EHR) systems - one of the most technically complex and impactful parts of what we build. Collaborate closely with product managers, designers, and other engineers to scope, plan, and deliver projects end to end. Grow. We invest in our engineers - through mentorship, technical stretch assignments, and the kind of exposure you'd normally have to wait years for. What You'll Bring A degree in Computer Science, Software Engineering, or a related field - or equivalent practical experience that demonstrates strong CS fundamentals. 0–2 years of professional software engineering experience. Internships, co-ops, and meaningful open-source contributions count. Solid grasp of data structures, algorithms, and object-oriented or functional programming concepts. Proficiency in at least one backend language; experience with Ruby, Python, Go, or Java is a plus. We primarily use Ruby on Rails. Comfort working with relational databases - you understand what a query is doing and why it might be slow. Ability to communicate clearly in writing and in conversation. You ask good questions and can explain your thinking. Intellectual curiosity and a bias toward figuring things out. Healthcare infrastructure is niche and complex - we'll teach you the domain, but you need to want to learn it. Bonus Points For Exposure to cloud platforms (AWS, GCP, o
