iOS Developer – Health & Wellbeing Tech Startup

Hybrid in Southampton (more flexible for right person)

Up to £100k + Bonus & Benefits


We’re exclusively partnered with an ambitious health and wellbeing startup that’s building a next-generation wellness platform from the ground up. This is not a re-skin or incremental update, it’s a brand-new product with a genuinely differentiated approach, designed to challenge how health tech is built and experienced.


Backed by a proven tech incubator, this business combines startup pace with real financial stability. You’ll be joining early, shaping a flagship iOS application, and having meaningful ownership over both the product and the technical direction.


The Opportunity

  • Build and own a native iOS application using Swift and SwiftUI
  • Work on a product where AI and ML are core to the architecture from day one
  • Create privacy-first, on-device features, no data harvesting, no compromises
  • Collaborate with a small, highly experienced product and engineering team
  • Influence architecture, technical standards, and user experience from the outset


What You’ll Be Doing

  • Designing, developing, and maintaining a high-quality iOS application
  • Integrating with Kotlin Multiplatform modules for shared business logic and data
  • Implementing on-device machine learning for personalised user experiences
  • Building integrations with Apple HealthKit and wearable data
  • Partnering closely with design to deliver intuitive, accessible, polished UI
  • Optimising for performance, battery efficiency, and offline-first usage
  • Supporting App Store submissions and release management


What We’re Looking For

  • Strong commercial experience with Swift and SwiftUI
  • Solid understanding of iOS architecture patterns (MVVM, Clean Architecture)
  • Experience with HealthKit and/or on-device ML is highly desirable
  • A strong focus on code quality, UX, and performance
  • Comfortable working in an early-stage environment with high ownership
  • Industry experience is a bonus but not essential


Why Join?

  • Build a product designed to genuinely improve people’s health and wellbeing
  • Early-stage team (currently 8 people) with plans to grow to 14–15 within 6 months
  • Backed by a successful tech incubator with a strong track record
  • High-trust, low-ego culture where impact matters more than titles
  • Hybrid role (with flexibility for the right candidates)


Package

  • Salary up to £100k, depending on experience
  • Strong benefits package (including performance based bonus)


If you’re an iOS engineer who wants real ownership, technical influence, and the chance to build something meaningful from the very beginning, this is well worth a conversation.
