Job description

We're building a unified patient-facing digital platform for a large enterprise healthcare organization — and we need a Senior Software Engineer who owns both mobile and web. This isn't a mobile-only or web-only role. You'll be shipping React Native features and React web experiences as equal parts of your day-to-day, working inside a cross-functional squad that moves fast and expects senior-level judgment, not just senior-level execution.

If you've spent your career waiting for someone to hand you a ticket, this isn't the right fit. If you've been the person who figures out what needs to be built, pushes back when something doesn't make sense, and ships it cleanly — keep reading.

What You'll Be Building

• Patient-facing mobile experiences in React Native across iOS and Android
• React web applications as an equal contribution alongside mobile
• API integrations and cross-system workflows as part of a full-stack squad
• Clean, tested, production-ready code with thorough PR reviews
• CI/CD pipelines, automated testing, and observability practices that the whole team relies on

What We Expect From You

• You work directly with Product — not just receiving requirements but shaping them. Story refinement, sprint estimation, feasibility pushback when needed.
• You coordinate with other squads. You understand that your work affects other teams and you manage those dependencies proactively.
• You contribute to architecture discussions. You have opinions about how systems should be designed and you can articulate the tradeoffs.
• You own your delivery. Sprint commitments, production readiness, post-launch support — all yours.
• You navigate ambiguity. When requirements are unclear you ask the right questions, not the wrong ones.

Required

• 5+ years of software engineering experience
• Production React Native mobile development — you've shipped apps to the App Store and Google Play
• Production React web development — mobile and web in the same role, not one or the other
• Advanced English — you're presenting tradeoffs to product stakeholders and coordinating with US-based engineering leads daily
• Located in Mexico — nearshore, CST-aligned hours

Nice to Have

• C# and Azure experience
• Healthcare or regulated industry background
• Epic / EHR / FHIR integration experience
• Interest in growing into a technical or engineering lead role
