Sr React Mobile/Web Dev

Job#: 3028972

Job Description:

Senior Front-End / Mobile Developer (React Native / ReactJS)

Location: Onshore | Level: Senior | Discipline: Front-End / Mobile

Role Overview

Baylor Scott & White Health (BSWH) is seeking a Senior Front-End / Mobile Developer with deep expertise in React Native and ReactJS to join a high-performing product delivery team. This role is responsible for building and evolving scalable, high-quality web and mobile applications in a highly regulated healthcare environment.

The ideal candidate brings strong hands-on engineering skills, practical architecture experience, and a quality-first mindset. You will partner closely with product, UX/UI, QA, and backend engineering teams to deliver reliable, performant, and accessible experiences across platforms.

A high level of experience and excellence is required regardless of location. Bonus (not required): familiarity with C#/.NET.

*Reputable companies a STRONG plus* - last win was a candidate from Mckesson

Key Responsibilities

Design, build, and maintain high-quality web and mobile applications using React Native and ReactJS.

Own end-to-end delivery of complex UI features with a strong focus on performance, reliability, usability, and accessibility.

Contribute to the design and implementation of scalable, maintainable application architecture across mobile and web, translating business and user needs into technical designs and implementation plans.

Write clean, well-structured, and well-documented code; establish and uphold engineering best practices.

Lead and participate in code reviews, ensuring consistency, maintainability, and adherence to standards.

Partner with backend engineers to define API contracts, data models, integration strategies, and error-handling patterns.

Optimize React Native applications for iOS and Android (e.g., offline storage, threading considerations, memory/performance tuning, startup time).

Coordinate releases and technical dependencies with other squads; proactively manage timelines and expectations.

Collaborate daily with Product, UX/UI, QA, and engineering stakeholders in an Agile/Scrum environment.

Mentor and support other developers through pairing, feedback, and technical guidance.

Required Qualifications

5+ years of professional experience in web and/or mobile application development.

3+ years of hands-on experience building production applications with React Native and ReactJS.

Strong proficiency with JavaScript/TypeScript, modern React patterns (hooks, context, component composition), and state management.

Experience building applications that consume RESTful JSON APIs (authentication, pagination, error handling, retries, and caching patterns).

Demonstrated ability to deliver within distributed teams and communicate clearly across time zones.

Strong debugging and troubleshooting skills across the UI stack (networking, state, rendering performance, device/platform issues).

Experience with Git-based workflows and CI/CD collaboration (branching, pull requests, reviews, release coordination).

Preferred / Nice-to-Have Qualifications

Bonus: Exposure to C#/.NET (reading/debugging services, collaborating on API contracts, or building small utilities).

Experience with component libraries/design systems and accessibility standards (e.g., WCAG).

Experience with micro-frontend patterns (MFE), monorepos, or shared UI platform initiatives.

Experience with testing frameworks (unit/integration/e2e) and automation (e.g., Jest, React Testing Library, Playwright, Detox).

Experience with GraphQL in addition to REST.

Experience with performance monitoring and instrumentation (logging, analytics, crash reporting).

Healthcare domain experience (Epic/EHR exposure) is a plus.

Experience using AI-assisted development tools responsibly (code suggestions, test generation, refactoring support).

Additional Notes for RecruitersPrimary focus = Senior React Native / ReactJS excellence. This is a senior UI engineering role (web + mobile). Prioritize strong React Native + ReactJS depth, quality-first engineering habits, and the ability to collaborate effectively in a distributed environment (onshore or nearshore).

Why "C# is a bonus": C#/.NET is a nice-to-have because this team partners closely with backend services and platform integrations that may be built in a .NET ecosystem. The intent is not to source a backend engineer, but a senior frontend developer who can comfortably collaborate on API contracts, understand service responses/data models, troubleshoot integration issues, and communicate effectively with .NET teams when needed.

How to screen for this (without over-filtering): Do not require hands-on C# production experience as a hard gate. Strong alternatives include candidates who have worked closely with backend stacks (Java/Kotlin/Node/.NET) and can describe end-to-end debugging and collaboration on API design, authentication flows, or performance concerns.

What "senior" means for this role: We are looking for developers who can operate independently, make strong technical decisions, raise quality through code reviews and mentoring, and deliver scalable UI architecture across mobile and web-not just implement tickets.
