Senior Mobile Engineer

Job Title: Senior Mobile Engineer (Remote)

Role Overview

We are partnering with a well-established, global technology-enabled services company that is modernizing how it builds software, including new customer-facing web and mobile experiences, a unified design system, and AI-powered capabilities across its products. Engineering, Product, and Design work together end to end to raise the bar for how software is designed, built, and operated.

AI is central to how this team builds. Engineers use agentic development as standard practice, moving from problem to production-ready code faster than traditional development allows while keeping the work reviewable and maintainable. The client is looking for a Senior Mobile Engineer who already works this way and wants to own significant parts of the mobile foundation. Mobile Engineers are software engineers first, held to the same bar for design, testing, performance, security, and production quality as everyone else, with added depth in mobile platforms, app architecture, device behavior, and release engineering. The applications handle sensitive personal data for a large member base, so reliability, privacy, and correctness are non-negotiable.

Key Responsibilities

• Own a mobile product area end to end, including its architecture, delivery, release path, and production behavior, as well as the shared capabilities other teams rely on
• Set technical direction for the mobile platform and shape the shared architecture behind a codebase that ships multiple apps, deciding what stays shared and what diverges
• Turn hard mobile problems into executable plans: frame the problem, sequence the work, and define what “done” looks like on a real device, with specs clear enough for AI agents to execute against
• Partner with Product, Design, and QA to shape solutions, bringing release mechanics, app-version adoption, device and OS behavior, and accessibility into decisions early
• Define how success is measured for your area using adoption, reliability, performance, and crash signals
• Own mobile production and platform health: lead incident response, ensure release and rollback readiness, stay ahead of OS, SDK, and store-policy changes, and turn recurring failures into structural fixes
• Remain accountable for the full mobile lifecycle within your area, including architecture, implementation, testing, review, release, and production
  
  

Education & Qualifications

• 5+ years of professional software engineering experience, including substantial mobile experience (guideline, not a hard gate)
• Experience shipping and operating production mobile apps at meaningful scale, with comfort in App Store and Google Play releases, staged rollouts, OTA updates, and production support
• Strong mobile architecture fundamentals: state and data management, caching, persistence, offline behavior, navigation, and performance, and the tradeoffs behind your choices
• Ability to work below the React Native abstraction: read and debug Swift or Kotlin, diagnose native crashes and build issues, and work with native modules and third-party SDKs
• Ability to design and verify a testing strategy, knowing what belongs at the unit, integration, end-to-end, and device level
• Systematic approach to diagnosing performance and reliability problems using profiling, crash diagnostics, and production telemetry rather than guessing
• Experience designing for mobile security, privacy, and accessibility: secure storage, authentication and session handling, sensitive-data flows, third-party SDK risk, and accessible patterns with VoiceOver and TalkBack
• Strong software engineering fundamentals beyond the mobile UI: APIs, data models, authentication flows, and service integrations
• Technical leadership: turning ambiguous problems into sound designs, explaining tradeoffs, reviewing others’ work with depth, and helping other engineers grow
• Already works AI-first: agentic tools are a primary surface for planning, implementation, testing, and review; delegates well-scoped work, catches plausible-but-wrong APIs and platform behavior, and remains accountable for what ships
  
  

Preferred Experience

• React Native + Expo (strongly preferred)
• Experience with Jest, Maestro, or similar testing tooling
• Experience with Java, Python, C#, Kotlin, Go, or similar
• Experience with Expo/EAS at scale
• Multi-app architecture on a shared codebase
• Contributions to open-source React Native tooling
  
  

Why Our Client

• Opportunity to own significant parts of the mobile foundation and set technical direction for the platform
• AI-first engineering culture where agentic development is standard equipment
• High-stakes applications where reliability, privacy, and correctness matter
• Engineering, Product, and Design working together end to end
• Technical leadership opportunity with a focus on helping other engineers grow
• Fully remote
  
  

Compensation, Benefits And Perks

• Base salary range: $140,000 – $220,000 USD (actual compensation depends on experience, education, geography, and scheduled hours)
• Full benefits package, including PTO, medical, dental, vision, and 401(k) with match
• Wellness resources and additional benefits
