Job description

My client is looking for a UI/UX Designer - a highly talented all-rounder who can take full ownership of the design function across their platform. This is a hands‑on role where you will drive the user experience, visual design, design systems, prototyping, and customer research yourself. There is no existing design team, so we’re looking for someone who thrives on autonomy and wants to have a significant impact.

My client is a highly regarded PE backed company with a successful history spanning several decades and a £50m+ turnover. They have won accolades as one of the UK's best workplaces. Their product sits at the intersection of tech, IoT, and connectivity, with a strong platform focus. You should be comfortable designing complex workflows, B2B SaaS experiences, and system‑level UI approaches. Experience in telco or adjacent tech industries is a plus, but strong consumer design experience with transferable skills is also valuable.

If you’re excited by the challenge of shaping a tech platform’s entire UX foundation from scratch, this is the role for you!

The Role

This role will encompass a range of responsibilities including but not limited to:

End‑to‑End Design Ownership

Own the complete design lifecycle: research, user flows, wireframes, prototypes, visual design, and final UI.

Develop and maintain our design system, component library, and visual language.

Create and test interactive prototypes using Figma, or similar tools.

Translate complex multi‑step workflows into intuitive, scalable experiences.

User Experience & Product Craft

Act as the senior design voice in the company – shaping design strategy, standards, and processes.

Map detailed user journeys, including edge cases, error handling, and exceptions.

Continuously improve usability through user research, interviews, and data‑driven insights.

Advocate for the customer and ensure UX is represented in product and engineering discussions.

Cross‑Functional Collaboration

Plan and facilitate UX discovery sessions, including stakeholder workshops, customer interviews, journey mapping, and problem‑framing sessions.

Translate research insights into actionable design decisions, prioritised flows, and validated prototypes.

Collaborate with engineering to ensure high‑quality implementation of designs.

Ideal Experience and Knowledge Sought

Core Experience

Proven experience as a UI / UX Designer or Product Designer, ideally in full‑stack design roles.

Strong portfolio showcasing complex flows, systems thinking, polished UI, and prototypes.

Demonstrated ability to work independently and own design end‑to‑end.

Deep expertise with Figma (components, auto‑layout, prototyping, variants, design tokens).

Industry & Domain Experience

Experience in tech platforms, telco, connectivity, IoT, or adjacent industries is ideal.

B2B SaaS experience strongly preferred; strong consumer‑product designers with relevant complexity exposure will also be considered.

Key Skills & Qualities

Exceptional UX depth: detailed flows, error states, edge‑case handling, multi‑user journeys.

Strong user empathy and customer‑centric thinking.

Comfortable navigating technical products, device workflows, or operational systems.

Self‑starter who works well with ambiguity and owns outcomes.

Nice‑to‑Have

Experience designing for data‑heavy dashboards, admin tools, or operational interfaces.

Familiarity with accessibility standards (WCAG 2.1+).

Experience in early‑stage or fast‑growing scale‑ups.

Exposure to IoT platforms or device / eSIM lifecycle experiences.

This is a permanent position and will require six months full time on site before moving to a hybrid situation.
