We’re looking for a Mobile Developer (iOS) who owns the full mobile layer - from the SDKs our partners integrate to the app our clients use in the field. You'll be deploying vision models on-device, shipping and supporting SDKs used by external engineering teams, and keeping a live product stable and improving. This is a hands-on role with real ownership - not a cog in a large mobile team, but the person who defines how we build and ship on mobile.

The Mobile Developer owns that layer end to end - from the SDKs our partners integrate to the app our clients use in the field. Your mission: own the mobile layer across SDK integrations, on-device ML, and ZIA Capture - and make it the most reliable part of what we ship.

  • You maintain and extend our camera SDK library, covering real-time image quality checks including blur, focus, lighting, exposure, framing overlays, and domain-specific capture guidance.
  • Own the on-device ML pipeline.
  • You deploy models end to end - PyTorch to Core ML conversion, quantisation, and performance profiling across device tiers.
  • You keep ZIA Capture stable - resolving bugs and shipping feature development that connects the mobile layer to our backend technology.
  • Standalone mobile developer - has operated as the sole or lead mobile developer on a product, with end-to-end ownership from scoping through to shipping and maintaining in production.
  • On-device ML in production - has shipped a mobile feature powered by an on-device ML model, not just a prototype. Evidence of model conversion pipelines, quantisation, performance profiling, and edge case handling. Bonus for vision models such as YOLO, Grounding DINO, or similar VLMs.
  • SDK built from scratch - has designed and shipped an SDK as a product, with evidence of versioning, documentation, and direct support of integrating engineers.
  • Live app ownership - has maintained a live application over time, fixing bugs, shipping incremental features, and keeping a product stable.
  • Evidence of curiosity - personal projects, experimental work, or active use of AI tooling.
  • On-device ML deployment - experience deploying vision models on-device using Core ML, ONNX Runtime, or TensorFlow Lite, with a solid understanding of model optimisation for mobile constraints.
  • Model conversion pipelines - PyTorch to Core ML or TFLite, with performance profiling across device tiers.
  • SPM packaging.
  • Active use of AI tooling.
  • Adaptable - you adjust quickly when priorities shift and are comfortable in a fast-moving environment.

Equity share options - we operate an EMI share option scheme, so when the company grows in value, you share in it. Pension - we contribute 3% through Penfold via salary sacrifice, with 5% employee contributions. Hybrid-first - minimum 2 days a week in our London office near Liverpool Street Station with flexibility built around delivery and trust.

  • Perks at Work - access to thousands of discounts across 30,000+ brands via CharlieHR, including up to 44% off cinema tickets and 15% off high street retailers.
  • Cycle to Work scheme - purchase a bike and accessories in a tax-efficient way through salary sacrifice via Cyclescheme.
  • Holiday Purchase scheme - buy up to 5 additional days of annual leave per year, spread across monthly salary deductions.
  • 25 days annual leave plus bank holidays, with the option to carry forward up to 3 days.
  • Friday office lunch - every Friday in the London office, lunch is on us.
  • AXA private medical insurance - Neurolabs covers the full premium. Cover includes cancer treatment, diagnostics, physiotherapy, counselling, and European travel insurance. Dental and optical handbooks also available.
