Location: London
Job Description:

Head of Mobile Engineering £130,000 | Hybrid – 2 days/week Central London

I am exclusively supporting a high‑growth mobile technology business whose products sit on tens of millions of phones globally. Their Android platform powers a revenue engine trusted by some of the world’s biggest carriers and they’re scaling fast!

We are recruiting for a Head of Mobile Engineering to own the entire mobile function: Android, iOS, the teams, the architecture, and the roadmap.

They are looking for a genuine department‑level leader + someone who will shape how they build, who they hire, and where the technology goes next.

What the role involves

  • Leading multi‑squad mobile engineering teams across Android and iOS (
  • Owning the technical architecture at global scale (10M+ MAU, enterprise‑grade compliance, tier-1 partner integrations)
  • Sitting at the table with C‑suite and commercial partners – translating engineering strategy into business outcomes
  • Driving the shift to modern declarative UI and evaluating next‑gen tooling including Kotlin Multiplatform
  • Maintaining real technical credibility – code reviews, architecture decisions, hands‑on problem solving alongside your teams

What they’re looking for

  • Deep Android / Kotlin background with serious architectural experience
  • A proven track record of structuring and scaling mobile engineering departments
  • Comfort operating at exec level (you can hold a commercial conversation as confidently as a technical one)
  • Scale‑up or growth‑stage company experience
  • iOS oversight capability alongside your Android depth
  • Kotlin Multiplatform experience is a real differentiator

This isn’t a role for someone who wants to delegate and manage upwards.

It’s for a technically sharp, commercially aware leader who wants to build something and leave their mark on a product used by millions.
