Senior React Native Engineer & Team Lead Patient Squad What to Expect

About the role

We are looking for a Senior Engineer who is ready to step up into disciplinary and technical leadership. You're a React Native expert who wants to lead a team where the "Definition of Done" includes making someone's recovery possible.

What you'll do

• Manage Multiple Projects: Effectively oversee and orchestrate development across several concurrent projects, including our white-label mobile apps, web applications, and core React Native mobile apps
• Shape the Engineering Culture: You are the mentor and disciplinary lead for the team. You don't just "manage" them; you empower them to grow, collaborating closely through Scrum while remaining hands-on with the code yourself
• Technical Sovereignty & Pragmatism: From day one, you own the technical roadmap of our application. You have a knack for cutting through complexity to make simple, pragmatic decisions on how we evolve our product to meet patient needs without over-engineering
• Pioneer AI & Automation: Actively use LLMs for coding and spearhead the development of a multi-agent environment to multiply the team's efficiency and capabilities
• Bridge Technology & Therapy: Work at the heart of Combined Care. You'll collaborate directly with Rehabilitation and Prevention experts to translate medical expertise into intuitive mobile experiences
• Set New Standards & Drive Innovation: As a key partner for Product and Design, you ensure that our frontend isn't just user-friendly, but a benchmark for digital health accessibility

What you'll need

• Mindset & Attitude: You possess a strong "can-do" attitude and a growth mindset, always eager to learn, adapt, and tackle new challenges with positivity
• React Native & Mobile Ecosystem: You have extensive experience in mobile application development, specifically within the React Native ecosystem, and a proven track record of mentoring or leading engineering teams
• OTA Updates: You are highly experienced in practicing Over-the-Air (OTA) updates to ensure smooth, continuous delivery for mobile applications
• AI-Assisted Engineering: You actively use LLMs in your daily coding workflows and have the knowledge and vision to build and integrate multi-agent environments for your team
• Frontend Mastery: You are an expert in modern JS frameworks with years of experience in both web/frontend and mobile development
• Full-Stack Understanding: You have a 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
• Quality & Testing: You have experience with end-to-end testing frameworks (like Cypress) and guide the team in implementing best practices for test coverage and code quality
• Value-Driven Execution: You can analyze complex customer requirements and quickly develop intuitive, pragmatic solutions that provide significant, tangible value to patients
