About Social Value Portal
Social Value Portal is the UK's leading platform for measuring and reporting social value - and it has been since 2014. The business works with organisations across the public, private, and voluntary sectors, helping them quantify and grow the positive impact they create. To date, more than £60bn in social value has been unlocked through its platform and customer relationships.
The team is growing and internationalising. The product sits at the heart of it all, and this role sits at the heart of the product.
The role
You'll join as a Product Designer reporting to the Head of Product, working closely day-to-day with the senior designer who has built the existing design system from the ground up. You're not starting from scratch - you'll inherit a full design system, a pattern library, an established research group, and a platform that's already live and scaling.
Initially you'll pick up defined projects and ad hoc improvements, getting to know the product and the team. As you settle in, you'll take on more complex research and strategic design work. It's a genuine step up -not a sideways move.
The office is based in Elephant and Castle, London (moving there around May 2026), with 2 to 3 days a week on-site.
Day to day: user research, wireframes, high-fidelity specs, prototype testing, and contributing to a design system that keeps the whole product coherent as it scales.
You'll:
Research and define user personas that reflect real behaviour and goals
Translate product requirements into wireframes and interactive prototypes
Run usability testing and validation - then act on what you learn
Deliver high-fidelity UX/UI specs for developers to implement
Maintain and evolve the SVP design system for consistent, scalable output
Collaborate with Product, Engineering, and Marketing across the full Agile cycle
Champion the user - advocate for customer-centric decisions across the product team
What you'll bring
Essential:
A strong product design portfolio demonstrating both process and outcome
Solid proficiency in Figma, Sketch, or Adobe XD
Proven experience applying UX principles, user research methods, and design systems
Working knowledge of Agile/Scrum environments and software development processes
Experience conducting qualitative and quantitative user research
Useful, not essential:
Experience using Productboard
Demonstrable use of AI tools within a design workflow
Salesforce and Lightning Design System (SLDS)
Benefits & culture
Financial: £42,000–£45,000 base, ethically invested pension matched to 5%, retail discounts with 200+ brands, salary sacrifice schemes (childcare, cycling, EV).
Flexibility: Hybrid working with 2–3 days in the London HQ. 25 days holiday plus bank holidays, your birthday off, and annual increases after 3 years.
Development: Access to The Knowledge Academy for accredited training.
Wellbeing: Private medical insurance, 24/7 Employee Assistance Programme, life assurance at 4x salary, elderlycare support, independent financial advice through Mintago.
Community: 6 paid volunteering days, gym access at the London HQ, and a business with a clear social purpose baked in from day one.

Location: Walworth Town Hall, London SE17 1RS
Working pattern: Hybrid - 2 to 3 days per week in the office
Contract: Permanent, full-time- Core hours- 9am-5:30pm
