Senior React Native Engineer (Mobile and Web)
First seen by Alion on Nov 4, 2026.
Senior Product Engineer (Mobile & Web)
About the Company
Wise Engineering is a software company where 90% of client relationships turn into long-term partnerships, and 70% of the team are senior-level engineers. We're hiring for one of our client products.
About the Project
An AI-powered nutrition platform embedded in the clinical pathway, starting with chronic pain care. Patients use a mobile app to log meals, track symptoms, and chat with an AI nutrition assistant, while dietitians use a web app to build protocols and approve AI-drafted plans.
About the Role
You will be the only front-end and mobile engineer, owning the patient mobile app and the dietitian web app end to end. You'll shape features together with the Founding Engineer and the Founders rather than wait for a detailed spec, and you'll see quickly how patients and dietitians respond to what you ship. Over six months, the role can grow into owning core AI features and protocol tools.
Responsibilities
Dietitian web app
Improve the clinician workflow: session notes, recipe library, and the front end for AI-assisted protocol generation
Build review-and-approve flows for AI-drafted protocols
Patient mobile app (iOS and Android)
Own mobile releases to the App Store and Google Play (ramp-up on the release process is supported during the first month)
Improve the UX around wearables integration, Voice AI features (UI), weight tracking, and recipe / grocery list navigation
Suggest and drive product improvements, not just implement specs
Engineering
Set up CI, automated mobile builds, and tests, and ensure HIPAA-grade handling of patient data on the client
Evolve interactive AI prototypes built by the CEO into production
Ship fixes and features for the clinics going live in November

Requirements
5+ years building production apps with React Native and TypeScript
Experience shipping to the App Store and Google Play (hands-on release experience is a plus; we'll help you ramp up)
Strong React web experience (React 19, Vite; react-admin or MUI is a plus)
Experience building UIs on top of AI services: streaming responses, slow or failed generations, review-and-approve flows
Daily, fluent use of AI coding tools, and comfort vibe-coding a prototype with a non-engineer founder
Strong product instinct: you turn a conversation into a good feature without a detailed spec
Nice to Have
HealthKit or Health Connect (wearables integration is on the roadmap)
Owning AI features end to end (prompts, model choice, quality checks), with a shipped LLM feature you can show

Early-stage startup experience
Experience & Soft Skills
English C1 or higher: fluent written and spoken, and you enjoy live brainstorming on calls
Proactive communicator: confirms priorities, flags trade-offs early, sends a short weekly written update
Autonomous and comfortable with ambiguity: you propose solutions rather than wait for a ticket
Optimistic about AI: you believe models can generate strong drafts and you design the review flows that make them safe
