Lead Mobile Developer

Remote working – once a month onsite in Epsom, Surrey

We’re partnering with a Tech for Good business, who are developing mission‑critical mobile and cloud‑based solution at scale across the business. Their products support users in real‑time environments where reliability, performance and resilience are essential. They are now rebuilding their mobile applications across iOS and Android, and are looking for a Lead Mobile Developer to support this.

As the Lead Mobile Developer, you will provide hands‑on technical leadership across the mobiles to help shape architecture, engineering standards and delivery practices whilst supporting a small development team.

Why this role is exciting:

• Greenfield rebuild of iOS & Android apps from the ground up… real ownership, real impact
• Modern cloud‑native platform, freshly modernised and built for scale
• Backed by new PE investment with ~20% growth and serious engineering headcount plans for the next 12 months

AI is a big deal here:

• Heavy investment in AI‑assisted engineering workflows and agentic development tooling
• Huge data assets (location, sensors, incident history) powering the next generation of the product
• Be part of shaping how AI accelerates mobile delivery in a safety‑critical environment

What they’re looking for:

• Strong native mobile experience – iOS (Swift/SwiftUI) and/or Android (Kotlin/Java)
• Solid grasp of REST APIs, real‑time app behaviour and authentication flows
• Interest in AI‑assisted development tools and modern engineering automation
• Leadership behaviours – mentoring, guiding technical decisions, collaborating cross‑functionally
