Senior UX Designers – AI‑Driven, B2B SaaS - UK (Remote) in Dartford

Senior UX Designers Wanted – AI‑Driven B2B SaaS. This is a fully remote, full-time role in the UK.

Must Have:

• Comfortable working in a fast‑growing start‑up
• Figma mastery
• An exceptional portfolio ready to submit
• SaaS experience and accustomed to small, high‑impact teams
• Ability to operate independently with high autonomy

This is one of the most exciting UX opportunities in the UK right now. Areti Group is exclusively partnered with a rapidly scaling, AI‑powered B2B SaaS company backed by major Series A funding. They’re expanding their product organisation and hiring Senior UX Designers to take full ownership of complex, high‑impact product areas across a cutting‑edge, data‑rich platform.

The Opportunity:

This is for designers who thrive in ambiguity, think in systems, and care deeply about craft. You’ll own design end‑to‑end — from discovery and research to polished, production‑ready UI. You’ll shape design patterns, elevate quality, and build intuitive, trustworthy AI‑driven experiences used by global enterprise clients. You’ll join a small, senior, high‑trust team where autonomy is real and your work has immediate impact.

What You’ll Own:

• End‑to‑End Product Design
• Lead complex product areas from problem definition → research → interaction design → visual design → engineering handoff
• Deliver scalable, elegant solutions across a data‑dense, AI‑powered platform
• Design intuitive, reliable AI interfaces that users depend on

Design Systems & Standards:

• Shape and evolve a modern design system
• Define interaction patterns and design standards
• Drive consistency and quality across product + engineering

Research & Insight:

• Lead interviews, usability tests and concept validation
• Turn qualitative + quantitative insights into clear direction
• Champion evidence‑based decision‑making

Cross‑Functional Influence:

• Partner closely with product and engineering
• Navigate complex dependencies and trade‑offs
• Operate as a strategic peer — not an order‑taker

What You Bring:

• Expert Figma skills — this is non‑negotiable
• 6+ years of UX & visual design experience in B2B SaaS
• A portfolio showcasing strong craft across complex, technical problems
• Proven end‑to‑end ownership of ambiguous design challenges
• Experience building and evolving design systems
• Strong research skills — interviews, testing, synthesis
• Confident influencing product + engineering partners
• Able to operate independently in a small, senior team
• Excellent communicator — written, verbal and visual

Bonus Points For:

• Experience designing AI‑driven interfaces
• HR tech, benefits, compensation or workforce platform experience
• Designing for data‑dense, permission‑heavy enterprise environments
• Using AI tools to accelerate design exploration
• Experience contributing to design practice‑building
• Metric‑driven design thinking

Mindset That Wins Here:

• You build — you don’t delegate
• You trust evidence over opinion
• You have strong opinions, held lightly
• You set a high bar for craft and clarity
• You’re proactive, self‑managing and thrive remotely
• You’re energised by AI’s impact on UX

Why You’ll Love This Role:

• Work anywhere in the UK — fully remote
• Shape a next‑gen AI platform used by global enterprises
• Join a small, senior, product‑first team
• Massive influence on design direction + systems
• High trust, high autonomy, direct access to leadership
• Backed by major Series A funding
• Fast, efficient interview process with pre‑arranged slots already booked

Interview Process:

• Informal chat with the Head of UX
• Design + portfolio interview (deep dive into process + craft)
• Technical interview
• Values + culture interview (final stage)

Benefits:

• Up to £70k salary
• 20% bonus
• Flexible working
• Share options
• Private healthcare

Final Note:

This is a high‑priority, exclusive hire with interview slots already locked in. Early applications — with portfolio included — will be prioritised.
