The Role
As a Senior React Native Engineer, you are an experienced, autonomous contributor who takes ownership of significant parts of a system and helps elevate the engineers around you.
This role sits at the intersection of hands‑on mobile engineering, architecture, and consulting. You will be the first mobile engineer on the initiative, responsible for defining the application foundations, establishing patterns, and making practical tooling decisions that enable long‑term success.
You will work directly with clients and collaborate closely with designers and backend engineers to ensure the mobile experience aligns cleanly with an existing platform, including shared design systems, domain models, and authentication.
This is a hybrid role, requiring 1 day per week at the office in central CDMX (Insurgentes Sur).
What You Will Be Doing
Technical Ownership & Delivery
- Start a new greenfield React Native application and drive it from early foundations through production release.
- Own the design and implementation of major features and core application architecture.
- Build high‑quality, scalable mobile experiences using React Native and modern JavaScript/TypeScript.
- Define and evolve patterns for navigation, state management, data access, error handling, performance, and testing.
- Integrate the mobile app into an existing platform by aligning with shared design systems, domain models, and authentication approaches.
- Consume a production GraphQL API implemented in .NET, collaborating with backend partners to evolve the schema as mobile requirements become clearer.
- Build data‑intensive views backed by paginated APIs, ensuring strong perceived performance and usability.
- Ensure testing, quality, and maintainability are built into the system from the start.
Leadership & Mentorship
- Work autonomously while guiding less‑experienced engineers through mentoring, pairing, and code reviews as the team grows.
- Lead small initiatives or workstreams and help ensure timely, high‑quality delivery.
- Act as a role model for strong engineering judgment, ownership, and collaboration.
Client & Stakeholder Collaboration
- Partner directly with client counterparts to understand user and business objectives.
- Collaborate closely with designers and partners on UX, wireframing, and high‑quality UI implementation.
- Communicate technical ideas clearly to both technical and non‑technical stakeholders.
- Contribute to building trust‑based client relationships as a reliable technical partner.
What Success Looks Like
- In your first 6–12 months, success means:
- You establish a strong mobile foundation and ship a production‑quality iOS and Android application.
- The mobile app integrates cleanly with the existing platform, aligning with shared design, domain, and authentication standards.
- You independently own and deliver key mobile components or features end‑to‑end.
- You proactively identify risks, trade‑offs, and improvement opportunities, addressing them early.
- Clients trust your judgment and value your contributions.
- Other engineers rely on you for guidance, clarity, and technical leadership as the mobile capability grows.
What You Should Have
- 6–8+ years of experience designing and building production software.
- Strong commercial experience building production mobile applications with React Native.
- Experience shipping and operating apps on both iOS and Android.
- Strong proficiency in modern JavaScript and TypeScript.
- Solid understanding of mobile application architecture, performance, and reliability.
- Experience consuming GraphQL APIs in production and collaborating on schema evolution.
- Solid understanding of SDLC practices, CI/CD, automated testing with tools such as Detox or Maestro, and code quality.
- Excellent written and spoken English communication skills (C1+ is highly preferred)
Bonus Points
- Experience defining architecture and patterns for greenfield products.
- Backend & cloud engineering exposure (.NET & Azure) to support cross‑team collaboration.
- Experience with cloud platforms and data‑intensive systems.
- Background in financial services, consulting, or similarly complex domains.
