Product Designer (Mobile)

Product Designer (Mobile) - London (Hybrid / Remote-First)

Product Designer wanted for a fast-growing B2B technology company building modern software for large-scale infrastructure and construction projects.

A rapidly scaling and well-funded tech business is looking to hire a Product Designer to take ownership of mobile experience design across a core product used by on-site teams delivering complex, high-value projects.

This is a highly impactful role where you will be the first dedicated mobile-focused designer
, shaping how critical workflows are experienced in real-world, non-desk environments.

The role is remote‑first, with flexibility across the UK and Europe and occasional in‑person collaboration.

• Own end‑to‑end mobile design, from initial concepts through to shipped product.
• Design intuitive, high‑quality experiences for users operating in real-world environments (e.g., on‑site, mobile‑first contexts).
• Define and evolve mobile interaction patterns that feel native and scalable.
• Work closely with product managers and engineers to shape features and ensure high‑quality delivery.
• Collaborate with engineers to ensure designs are implemented accurately and effectively.
• Contribute to and evolve the design system, particularly for mobile components.

• Have 4+ years’ experience in product design, with a strong focus on mobile (iOS, Android or cross‑platform).
• Have experience designing for complex workflows, ideally in B2B or SaaS environments.
• Have strong interaction design skills (user flows, states, edge cases – not just visual design).
• Are comfortable working closely with engineers and understanding technical constraints.
• Can take ownership across the full design lifecycle, from discovery through to QA.
• Ideally have experience with design systems and/or cross‑platform frameworks (e.g., Flutter).
