Lisboa, Portugal Chrono Health Tempo inteiro

Company Description At Chrono Health, we're building the first AI health copilot for people with chronic conditions. A companion that truly understands patients, learns from their health over time, and helps them act before things spiral. Healthcare today is fragmented and reactive. We're flipping that paradigm. Chrono Health puts people back in control of their health, helping them understand their condition, improve it, and live with more quality of life and peace of mind. This isn't just another health app. It's the start of a movement, where patients finally have a partner they can trust, and where technology serves the people it matters most to. Role Description As a Senior Frontend Developer at Chrono Health, you will shape the core web experience of our AI-powered health companion. This is a unique opportunity for a product-minded, entrepreneurial engineer to build at the intersection of healthcare, software, and intelligent design — crafting interfaces that make complex health data feel human, intuitive, and actionable. We are adopting a vibe coding approach: leveraging AI and AI-assisted development tools as creative partners in the engineering process. You'll lead prompt-driven workflows, AI-accelerated prototyping, and intelligent automation to deliver fast, beautiful, and scalable web applications. This role isn't about writing every line of code by hand — it's about combining technical excellence, creative direction, and AI-augmented development to move with both speed and precision. You'll collaborate closely with the product, design, and backend teams to architect and deliver a frontend platform that empowers people with chronic conditions to understand their health, stay engaged, and take meaningful action every day. What will you do? Develop a mobile solution using React Native and TypeScript, blending speed, creativity, and precision. AI tools (e.g. Copilot, Cursor, Claude Code, Windsurf, etc.) are your collaborators, not crutches. Engineer and refine prompts to generate, debug, and optimize code efficiently — curating AI outputs into scalable, maintainable systems. Collaborate closely with product managers, designers, and backend engineers Ensure top-tier code quality, testing coverage, and performance optimization Identify and address technical debt through thoughtful refactoring Manage app releases for both iOS and Android (App Store / Google Play) Contribute to CI/CD improvements for mobile development Step in where needed — we're a startup, adaptability is key Communicate effectively in English, both written and spoken What makes you a great fit? Background: Bachelor's in Computer Science, Engineering, or equivalent hands-on experience Experience: 5+ years in software development, with strong mobile focus Expertise: Advanced skills in React Native, Expo and JavaScript/TypeScript. Execution excellence: Proven problemsolving, debugging, and performance tuning abilities Team-ready: Strong experience with Git/GitHub and collaborative development workflows Production-ready: Track record of shipping and maintaining high-quality mobile apps Design-aware: Solid understanding of UI/UX best practices Tooling: Familiar with CI/CD pipelines and automated testing tools (a plus) Security-aware: Knowledge of authentication/authorization protocols (OAuth, JWT) Bonus: Experience or strong interest with AI-assisted development tools (e.g., Copilot, Cursor, Claude Code) and cloud platforms (AWS, GCP, Azure)
