Product Designer (Mobile)

roduct Designer (Mobile) - B2B SaaS | London (Hybrid) | Up to £75k


I'm working with a fast-growing SaaS company looking for their first dedicated mobile Product Designer.


This is not a typical design role.

You'll be building mobile tools used on construction sites-by people working outdoors, on shared devices, often with poor connectivity.


Think:

Task updates

Photo logging

Daily reporting

Voice capture

If you've designed for clean, ideal conditions-this will feel very different.


The role

  • Own mobile design end-to-end (iOS & Android - Flutter)
  • Design complex workflows, not just screens
  • Work closely with engineers to get details right in production
  • Design for real-world constraints (offline, speed, usability under pressure)
  • Help raise the bar from "we have an app" "this is genuinely great to use"


What they're looking for

  • 4+ years in product design
  • Strong mobile experience
  • Experience with complex, multi-step workflows
  • Comfortable working closely with engineers
  • Someone who takes ownership and pushes for quality


Bonus:

  • B2B / SaaS
  • Field / operational tools
  • Flutter / cross-platform experience


Probably not for you if:

  • You focus mainly on visual polish over usability
  • You prefer handing off designs rather than owning outcomes
  • You haven't worked on complex product problems


Why this role is interesting

  • First mobile-focused designer in the team
  • High ownership + real product impact
  • Mobile is a key growth area for 2026
  • Small, senior team
