Job Description

About the Client


We are recruiting on behalf of a fast-scaling, high-intensity AI startup backed by top-tier global venture capital funds. They build custom, AI-native software to modernize complex, real-world field operations.


They are seeking their first dedicated Mobile Application Engineer to own the entire mobile surface end-to-end. We welcome global applicants, full visa sponsorship and complete relocation packages are available for candidate willing to move to London.


What You'll Do


  • End-to-End Ownership: Own mobile products from field discovery and spec to building, shipping, and release management across iOS and Android.
  • Field-Driven Engineering: Sit directly with non-technical domain experts on-site to understand how they work and translate real-world chaos into intuitive UX.
  • Build & Scale: Develop production-grade cross-platform apps (React Native + TypeScript) and drop into native code (Swift/Kotlin) when needed for hardware/sensor integrations.
  • Architect for Reality: Build offline-first architectures featuring local persistence, conflict resolution, and reliable sync mechanisms for low-connectivity environments.
  • AI Integration: Embed cutting-edge AI features (LLMs, agents, on-device/voice) into core mobile workflows.


Must-Have Requirements


  • Exceptional Engineering Pedigree: Proven track record at a top tech company, AI lab, trading firm, or fast-scaling startup.
  • React Native & TypeScript: Strong proficiency with RN + TS (or equivalent cross-platform stacks), coupled with solid iOS/Android native fundamentals (Swift/Kotlin).
  • Complex & Offline Workflows: Demonstrated experience building offline-first systems and complex state architectures—not just basic CRUD apps.
  • Backend Comfort: Ability to build and consume backend services supporting complex mobile workflows (Python is a plus).
  • Customer Proximity: Highly comfortable interacting directly with non-technical users in the field.


Who Will Thrive Here (Green Flags)


  • Founder Mindset: High agency, high ownership, low ego. You build order out of chaos.
  • Speed & Quality: You ship fast at production grade.
  • High Intensity: Thrives in an ambitious, hard-working startup environment.
  • Relocation Ready: Excited to move to London to join an in-person, highly collaborative engineering team.
