Frontend Software Engineer

Frontend Software Engineer

Sofía wants to change the way millions of people take care of their health by offering a complete, easy to understand, and close plan to anyone who wants to live a healthier life. We are scaling our team quickly and we are looking for people who are curious, motivated, and excited to grow a fast-paced startup with a real purpose: to improve the health system in Mexico.

In this process we are looking for a Frontend Software Engineer with experience in React and React Native to build Sofía's digital experience. Your mission here is to make every interaction of our members with the app and the web simple, fast, and reliable, with code that scales as fast as we do.

What you will do:

Product and development

• Develop and maintain responsive web and mobile apps with React and React Native.
• Integrate GraphQL queries and mutations for seamless frontend and backend communication.
• Implement third-party APIs and UI libraries that enhance our products.

Quality and scalability

• Write simple, maintainable, and scalable code.
• Apply good testing and debugging practices before a bug reaches a member.
• Diagnose, optimize, and keep the stack updated.

Cross-functional collaboration

• Define with the backend team the requirements of each query and mutation, explaining the what, the how, and the why.
• Work with Product, Design, and other areas to convert needs into technical solutions.
• Question designs or flows when they are not up to par: you are one of those people who says "this can be done better" and proposes how.

AI and innovation

• Use AI tools in your day to day to accelerate development, testing, and documentation.
• Propose new technologies and ideas that grow our products.

What we are looking for:

• 5+ years of experience in frontend development.
• Domination of React and React Native, with a solid understanding of frontend architectures.
• Successful projects with React, React Native, and GraphQL that you can show us.
• Experience integrating third-party APIs and UI libraries.
• You use AI to code (Cursor, Claude Code, GitHub Copilot or similar): you know how to give good context and critically review what it generates.
• You communicate clearly with technical and non-technical profiles.
• Autonomy, without losing collaboration, in a fast-paced environment.
• Constant curiosity: you keep up with the new things in the industry.

Plus (not must, but add points)

• Experience building functionalities with LLMs or AI-based products.
• Previous experience in health (healthtech), insurance (insuretech), or fintech.
• Knowledge of a backend language, ideally Python, and willingness to dive into backend code in simple queries and mutations.

Interview process:

1. Interview with Flo, from the People team.
2. Technical interview with Ricardo, as the leader of the work unit.
3. Technical exercise with several people from the unit, and they get to know each other!
4. Cultural interviews to see if we are aligned.
