Job description

Senior Interior Designer (Retail & Brand Environments)

• Salary: up to £55,000 pe annum, depending on experience
• Location: London studio
• Working pattern: Full time, studio-based
• Experience: 6+ years
• Software: Vectorworks, Adobe Creative Suite, and Cinema 4D preferred, but will consider SketchUp/V-Ray
• Sectors: Retail, brand environments, hospitality, workspace, and residential

About the Studio

This is a well-established London design studio with decades of work for international brands behind it. Its roots are in making, and that still shows in how the team thinks and draws.

Today it works across retail, hospitality, workspace, residential, and brand experience, with a strong list of international lifestyle and sports brands. Big rollouts sit alongside one-off flagships and temporary spaces.

The approach is grounded. Spaces should invite people in, not just sell to them. Design what's needed and nothing more, and detail it so it can actually be built.

It's a friendly, curious team, with a strong creative culture outside project work and a real commitment to doing business responsibly.

About the Role

This is a physical spaces role. If your background is UX, UI, or digital product design, this one isn't for you.

It's a permanent, hands-on senior seat in a studio where the drawing pack matters as much as the big idea. You'll be on the tools, producing work yourself as well as leading it. You'll take projects from first concept to on-site delivery, often for brands with global ambitions, and across a real range of scales: a temporary activation one month, a flagship or international rollout the next. Most of the work is retail, and projects move quickly, often from brief to start in a couple of weeks.

You’ll work alongside your peers at every stage of a project, take steer from the project leads, and bring the more junior designers along with you.

Your Days Will Look Something Like This

• Leading design from first concept through to on-site implementation
• Developing concepts, material palettes, and spatial strategies that feel true to each brand
• Designing custom fixtures, display systems, and furniture, and working with fabricators to prototype and test them
• Creating visuals and presentations in SketchUp and V-Ray (or Cinema 4D) and Adobe Creative Suite
• Developing concepts that travel globally, then adapting them to local buildings, cultures, and operations
• Presenting to clients and building strong working relationships with them
• Coordinating contractors, suppliers, and consultants, and getting out on site
• Managing your own time and workload across several live projects
• Delegating to, guiding, and mentoring the junior designers

You Might Be Our Perfect Match If

• You have 8+ years in interior or spatial design, with experience at every stage from concept to on-site implementation
• Your portfolio covers a range of project scales, ideally including retail, brand environments, or hospitality
• You detail with confidence: you know how things go together and enjoy a good junction
• You're fluent in Vectorworks for 2D and 3D and in Adobe Creative Suite, and confident visualising in SketchUp and V-Ray. Cinema 4D is a nice-to-have, not a must
• You've coordinated contractors and fabricators and delivered on site
• You have well-established habits for managing your time and workload
• You've guided or mentored more junior designers and enjoy doing it alongside your own hands-on work
• You stay curious beyond the day job, with interests across creative disciplines, culture, and the world around you
