At Caspar Health, we don’t just build software—we deliver Combined Care. We bridge the gap between technology and medical expertise to help people regain their independence after illness or accidents. For us, digital innovation only works when paired with personal, human medical support.

We are looking for a Senior Engineer with initial experience in a leadership role.

• The "Combined Care" Mission: Develop intuitive frontends that empower both patients and medical professionals, ensuring technology enhances—not replaces—the human touch.
• People Leadership: You are the anchor of the team. You will lead, coach, and take full responsibility for the growth and well-being of your fellow engineers.
• Strategic Ownership: Directly collaborate with other Product Squads and Clinical teams to translate medical needs into seamless digital experiences.

You’re a fit if you are a React Native expert who wants to lead a team where the "Definition of Done" includes making someone's recovery possible.

• Extensive experience in mobile application development, specifically within the React Native ecosystem, and a proven track record of mentoring or leading engineering teams.
• Highly experienced in practicing Over-the-Air (OTA) updates to ensure smooth, continuous delivery for mobile applications.
• Actively use LLMs in daily coding workflows and have the knowledge and vision to build and integrate multi-agent environments for your team.
• Expert in modern JS frameworks with years of experience in both web/frontend and mobile development.
• Strong interest in backend technologies (such as Node.js, TypeScript, and/or Ruby on Rails) and can effectively bridge the gap between frontend and backend architectures.
• Experience with end-to-end testing frameworks (like Cypress) and guide the team in implementing best practices for test coverage and code quality.
• Deep understanding of state management frameworks (like RxJS or Redux) and help your team utilize them efficiently.
• Ability to analyze complex customer requirements and quickly develop intuitive, pragmatic solutions that provide significant, tangible value to patients.

Requirements

• Manage multiple projects effectively, overseeing development across several concurrent projects, including white-label mobile apps, web applications, and core React Native mobile apps.
• Shape the engineering culture by mentoring and empowering the team, collaborating closely through Scrum while remaining hands-on with the code.
• Own the technical roadmap of our application, making simple, pragmatic decisions on how to evolve our product to meet patient needs without over-engineering.
• Actively use LLMs for coding and spearhead the development of a multi-agent environment to multiply the team's efficiency and capabilities.
• Collaborate directly with Rehabilitation and Prevention experts to translate medical expertise into intuitive mobile experiences.
• Ensure that our frontend is user-friendly and a benchmark for digital health accessibility, defining processes and introducing best practices that keep our development at the cutting edge.
