Job Description:

Our mobile platform powers a nationwide field workforce, enabling accurate, high‑quality on‑site inspections through a single app. This isn’t a demo app or a lab experiment—it’s software used every day at real job sites, often under tough conditions like poor connectivity, unpredictable environments, and tight timelines. As a Senior React Native Mobile Engineer, you’ll help shape the mobile experiences that drive the business. This is a hands‑on, high‑impact role where you’ll lead major initiatives, build new capabilities, and raise the bar for reliability, performance, and quality across both iOS and Android.

Job Responsibility:

  • Build and Innovate: Develop new features for our mobile applications and help architect new mobile product initiatives
  • Translate real‑world field needs into elegant, durable mobile solutions
  • Lead Major Initiatives: Own technical design, tradeoffs, and delivery for key areas of the app—from early discovery through rollout and iteration
  • Act as a technical leader within the mobile team, setting direction and standards
  • Engineer for the Field: Improve offline‑first workflows, background sync, and data integrity in low‑connectivity environments
  • Design systems that are resilient, observable, and recover gracefully when things go wrong
  • Evolve the Mobile Architecture: Design, implement, and maintain a scalable React Native codebase, including navigation, state management, modularity, offline patterns, and performance optimization
  • Ship with Confidence: Leverage modern mobile testing practices, instrumentation, and CI/CD pipelines to improve reliability and speed of delivery
  • Own quality in production, not just at merge time
  • Collaborate and Mentor: Work closely with a small, high‑performing team
  • Participate in code reviews, pair programming, and technical discussions
  • Help mentor junior engineers and raise the overall bar for mobile engineering

Requirements:

  • Mobile engineering experience: Proven experience building and maintaining production mobile apps. Experience with apps used in real‑world, high‑variability environments is a strong plus
  • React Native expertise: Deep experience with React Native, React, and modern JavaScript/TypeScript patterns
  • Strong architectural instincts: Comfort designing modular, maintainable app architectures, including navigation, state management, offline patterns, and performance tuning
  • API integration experience: Experience integrating with RESTful APIs and collaborating with backend teams to design mobile‑friendly endpoints
  • Ownership mindset: Strong problem‑solving skills, critical thinking, and a bias toward action
  • Education: Bachelor’s degree in Computer Science or related field, or equivalent practical experience

Nice to have:

  • Native & Platform Depth: Experience with native iOS (Swift/Objective‑C) and/or Android (Kotlin/Java)
  • Developer Experience & Quality: Hands‑on experience with mobile CI/CD pipelines, release workflows, and observability
  • Capture Tech, AR/3D, and On‑Device Intelligence: Experience with AR frameworks (ARKit / ARCore) for spatial capture or scanning
  • Integrating mobile experiences with on‑device AI/ML models
  • 3D rendering experience (SceneKit, RealityKit, Three.js, Unity, or similar)
