Job description

At H1, we believe access to the best healthcare information is a basic human right. Our mission is to provide a platform that can optimally inform every doctor interaction globally. This promotes health equity and builds needed trust in healthcare systems.

Visit h1.co to learn more about us.

We are looking for Full Stack Software Engineers to join a dedicated team building and evolving a clinical data platform serving the clinical operations space. You will develop web application features that surface healthcare insights — working across the full stack from backend services to user‑facing interfaces.

This is a hands‑on engineering role embedded in a fast‑paced product team. You will build features that connect large‑scale data pipelines to intuitive front‑end experiences, working closely with product designers, data engineers, and clinical stakeholders. You should be comfortable taking ownership of features end‑to‑end and shipping quality code in an agile environment.

WHAT YOU'LL DO AT H1

• Develop and maintain full stack features for web applications using .NET (backend) and Vue.js (frontend)
• Build and consume RESTful APIs and JSON‑based data contracts that integrate with large‑scale clinical data pipelines
• Collaborate with product designers to implement responsive, accessible, and performant user interfaces
• Work with data engineers and backend teams to ensure efficient data flow between services, pipelines, and front‑end layers
• Write clean, well‑tested, maintainable code and participate in code reviews to uphold engineering standards
• Contribute to sprint planning, technical design discussions, and architecture decisions within the product team
• Troubleshoot and resolve issues across the stack — from database queries through API layers to UI rendering

ABOUT YOU

• A pragmatic engineer who ships — you take ownership of features from design through deployment
• Someone who cares about user experience and works well with designers to translate mockups into polished, functional interfaces
• Confident working across the stack and comfortable context‑switching between backend logic and frontend implementation
• A strong communicator who holds their own in meetings, including when you're the only remote participant in the room
• Experienced collaborating across time zones with India‑based and EU‑based distributed teams

REQUIREMENTS

• 5+ years of professional full stack development experience
• Strong proficiency in .NET (C#) for backend development — building APIs, services, and server‑side logic
• Hands‑on experience with Vue.js for frontend development; familiarity with modern JavaScript/TypeScript ecosystems
• Experience with TypeScript and Entity Framework
• Solid understanding of RESTful API design, JSON data formats, and client‑server communication patterns
• Experience with relational databases (SQL Server preferred) and writing performant queries
• Familiarity with CI/CD pipelines, version control (Git), and agile development practices
• Exposure to Azure cloud platforms and containerized deployment environments is a plus
• Experience in healthcare, life sciences, pharma, or clinical research is a plus
• Comfortable working independently in a hybrid setting with a distributed, cross‑timezone team

H1 OFFERS

• Competitive salary + equity (RSUs)
• 5 weeks paid vacation + company‑wide wellness days
• Pension with employer match
• Health, mobile phone & home office stipends
• A culture built on hygge — low hierarchy, high trust, and real autonomy over your work
• Monthly team social (søbar)
• Direct embed with one of the world's top 20 pharmaceutical companies, working on a global initiative with real impact on how clinical research gets done
• Exposure to H1's broader life sciences client network across biotech, pharma, and digital health
