Job description

Freelance Network | Mid-Senior UI Designer

We are looking for an experienced Freelance Mid-Senior UI Designer to support our Experience Department and help shape thoughtful, high-quality digital experiences for upcoming projects.

About the Role

This role is hands‑on and varied. You’ll work across websites and digital products, collaborating closely with designers, strategists, and developers to create work that is clear, scalable, and beautifully executed. We move at pace, care deeply about craft, and take real pride in delivering outstanding work.

The work

You’ll support a mix of:

• Website redesign projects
• Website reskin and UI refresh work
• UI audits and optimisation
• Ongoing UI support through retainers
• Digital products that sit alongside websites

This includes B2B websites, products, and intelligent experiences.

What you’ll bring to the role

You’re a confident UI designer with a strong visual eye and a practical mindset.

You’re forward‑thinking in your approach to design, staying on top of emerging trends, tools, and opportunities.

You enjoy using technology to streamline workflows and explore how AI and intelligent experiences can elevate designs, both in how we work and what we create.

You’re genuinely fluent in Figma. You enjoy building thoughtful, componentised design systems using auto‑layout, variants, and styles, and you design in a way that supports smooth design‑to‑code workflows.

You have experience designing for B2B environments across complex journeys and multiple audiences.

You think beyond static screens. You design interactions, states, and simple motion, and you use prototyping to clearly communicate intent and behaviour.

You’re collaborative by nature and enjoy working with developers, designing with build in mind and iterating confidently within technical frameworks and CMS constraints.

You work closely with UX designers and strategists, getting involved early and helping turn ideas, insight, and strategy into clear, usable UI. You like shared thinking, open conversations, and building things together.

Accessibility is part of how you work. You design with WCAG AA standards in mind from the start, creating inclusive interfaces with clear focus states, strong contrast, and accessible layouts.

You’re comfortable working in agency environments and understand the realities of time allocation, budget, and delivery. You adapt your approach to suit each project while keeping quality high and work moving forward.

Experience we’re excited about

• Strong UI portfolio with website and digital product work.
• Experience designing for WordPress sites.
• Bonus experience with Webflow, Shopify, or headless CMS setups.

Who you’ll work with

You’ll work with Hallam’s Experience team, a tight‑knit group across UX, UI, and development with big ambitions and high standards. We’re always innovating, pushing boundaries, and working closely together to make work that’s thoughtful, scalable, and well‑crafted. We take the work seriously, not ourselves, and we care deeply about strong design systems, smooth delivery, and doing great work for our clients.

About Hallam

We’re not just some self‑obsessed agency promising table tennis and unlimited snacks in exchange for your soul. And that’s why we’ll always show up with something to say, not just something to sell.

We share a mission to deliver outstanding work with purpose. We’re here to do business in a better way: to work hard to do the right things, not only for our clients but for our people and the world around us.

Work should exist to make life better and we are a great place to work. Hallam has been chosen by its employees as one of the best places to work, and in the top 40 marketing employers in the UK.

You’ll join a team of more than 60 talented digital geeks who love everything from board game nights to agency trips out to a post‑work tipple(s).

What’s it like working with Hallam? You’ll get to work for a progressive agency that’s driven by its people and values, not just profit. We’ll set you off on your personalised freelance onboarding program where you’ll get to know us; your point of contact and the experience team as well as how we do things around here through our proven design operations and processes.

We highly encourage applicants from under‑represented ethnic groups and LGBTQ communities. Throughout the recruitment process, we will strive to make interviews as diverse and gender‑balanced as possible for impartiality. As long as you’re qualified, you’ll receive equal consideration for employment regardless of race, religion, colour, gender or disability.
