Senior Mobile Product Designer (B2B SaaS)

Product Designer (Mobile) – B2B SaaS | London (Hybrid) or Remote | 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

✅ 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

🚫 Probably not for you if:

• You focus mainly on visual polish over usability
• You prefer handing off designs rather than owning outcomes

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
