Mobile Application Developer (HealthTech)

Permanent, Full Time

Remote (UK) — handful of in-person days per month

Precision HealthTech is building the next generation of intelligent, patient-centric healthcare.

Formed through the evolution of Healthy.io (UK), Precision HealthTech combines proven, regulated digital health solutions with new investment, ambition, and scale. Our flagship product, Minuteful for Wound , is a CE-marked, AI-powered platform that transforms a standard smartphone into a clinical-grade wound assessment tool - bringing precision measurement, structured clinical insight, and real-time tracking directly into the hands of clinicians and patients.

We are entering a new phase: scaling across the NHS and international markets, expanding our product portfolio, and redefining how care is delivered outside traditional settings. Our technology enables clinicians to work smarter, improves consistency and outcomes, and empowers patients to actively participate in their healing journey.

At Precision HealthTech, we are not just digitising existing pathways - we are redesigning them. This is an opportunity to shape the future of regulated digital healthcare at scale, in an organisation that combines deep clinical credibility with the agility of a high-growth technology company.

We are building a small, high-trust team where people take ownership, work collaboratively, and focus on delivering meaningful impact in healthcare. Our work is grounded in a few core principles:

• Patients first: Every product must measurably improve outcomes and access.
• Precision in everything : Clinical-grade accuracy, operational reliability, and data integrity.
• Trust and transparency: With staff, clients, and partners. Recruitment, culture, and decision-making shaped with staff, not done to them.
• Bold innovation, quiet delivery : World class technology delivered seamlessly and simply.
• Local roots and history with global relevancy : proven UK centre of excellence powering international health impact.

What you will do

You will take ownership of the iOS and Android apps behind a platform used by NHS clinicians and patients at a key moment of transition. Your first priority will be to get up to speed with the existing codebases through knowledge transfer, building confidence in how the apps work and how they’re released.

You will work across both platforms, maintaining and improving a real-time, on-device camera and ML pipeline. This includes delivering features, building UI changes, and ensuring the apps remain stable and reliable in real-world use.

This is a hands-on role where you will be writing code, shipping features, and managing releases to the App Store and Play Store within a regulated environment. You will work closely with QA to ensure changes are properly tested and documented before release.

As we scale, you will contribute to improving how we build and release mobile software, while supporting the continued development of a complex, real-time mobile application.

• 4–7 years of mobile development with strong iOS experience (Swift).
• Camera and real-time video processing experience (AVFoundation or equivalent).
• On-device ML inference experience (CoreML or equivalent). The app runs ML models locally in real-time.
• Enough Android capability to maintain the second platform, ship changes, and fix bugs.
• Willingness to get into computer vision territory — the pipeline involves feature extraction and geometric analysis. You don’t need to be an expert going in, but you need to be comfortable learning.
• Previous work on healthcare or clinical apps. If you’ve shipped a mobile product in a regulated environment - where releases need documentation, where changes go through design control, and where the app review process involves more than just Apple or Google - you’ll hit the ground faster.

• Image processing (OpenCV, Metal, Accelerate).
• Offline-first architecture experience.
• Cross-platform thinking (KMP, Flutter) for longer-term strategy.

• Remote role, UK-based. You’ll need to attend in-person meetings and team working days a handful of times per month (typically 2–4 days). These will predominantly be in London.
