Job summary

Motum is seeking a Senior Full-Stack Engineer, Mobile to build and ship a cross-platform app from the ground up, then work across the stack, interface, APIs, and services. The role demands startup-mentality, high ownership, and collaboration with US-based teams in a fully remote setting.

You will tackle Angular, NestJS, Postgres on the backend and React Native on mobile, delivering smooth UX and real-time conversations in a health-tech context.

Qualifications

• Hands-on experience with Angular, NestJS, and Postgres (or the proven ability to ramp into them quickly).
• Strong mobile experience — React Native (or native iOS/Android) — with apps shipped in production
• Comfortable owning both the mobile app and the backend and APIs behind it (REST/GraphQL)
• An eye for polished, human-centered UX
• A bias to ship and comfort iterating quickly on a small team
• Bonus: experience bridging web and mobile (e.g., Ionic/Capacitor, which pair well with Angular), real-time chat/voice, app-store release ownership, consumer-health or healthcare experience

Responsibilities

• Build and own the company's mobile app (iOS and Android), from UI to release
• Work full-stack in their Angular / NestJS / Postgres stack, plus the mobile layer on top
• Craft smooth, accessible, trustworthy UX for a sensitive, emotional use case
• Build real-time chat and conversational (and potentially voice) experiences
• Ship fast, iterate on real user feedback, and help set mobile engineering standards
• Build responsibly with sensitive health data (HIPAA-aware)
