Job description

Senior Interior Designer — Fashion Retail and Brand Environments

Location: East London, hybrid (2 to 3 days in the studio)

Salary: Up to £55,000, dependent on experience

Job Type: Permanent

Software: SketchUp essential, Vectorworks advantageous

Sector: Fashion retail and branded environments

The Snapshot

• Small, independent East London studio designing retail and brand environments for fashion labels with a real following
• A senior role: you'll own projects end to end, and you'll be trusted to run them
• This is an interior designer's job, not a 3D visualiser's. SketchUp is how you think and test space, not the whole role
• Fashion retail experience is essential: streetwear, trend-led, hype-driven brands, the sort of stores people queue for
• Physical spaces, not digital. Real materials, real walls, real opening nights
• Hybrid, 2 to 3 days a week in the studio

About the Studio

An independent East London studio with a reputation for retail and fashion environments that are properly resolved. Small by design, ambitious by nature. They pick quality over volume, and they work closely with a roster of trend-led fashion brands to build stores that feel as considered as the product on the rails.

There's no hierarchy to work around. People are trusted to take ownership, bring ideas, and shape the studio as well as the projects. Less process than a big agency, a great deal more influence. With the business heading into a growth phase, this is a chance to become one of the people who defines what comes next.

About the Role

This is a senior seat. You'll lead fashion retail and brand environment projects from first sketch to opening day: concept, space planning, materiality, detailing, and the technical information that makes the whole thing buildable. You'll work directly with studio leadership on creative direction, and you'll be the one holding the quality line as a project moves through every stage.

You'll also be a senior voice in a small team, setting the standard for the work around you. It's hands‑on throughout: the designer who draws it is the designer who sees it through.

Your Days Will Look Something Like This

• Leading retail and fashion environment concepts from first ideas through to delivery
• Space planning, materiality, and detailing: solving the spatial and material problems that make a store work as well as it looks
• Producing design packages, technical information, and buildable detail, so ideas make it off the screen and onto the shop floor
• Working directly with studio leadership on creative development and project direction
• Running projects day to day, coordinating activity across every stage, and holding quality from concept to completion
• Owning relationships with clients, suppliers, and everyone else involved in getting a store open
• Mentoring and guiding colleagues while staying fully hands‑on with your own work

You Might Be Our Perfect Match If

• You have significant experience delivering fashion retail or branded environment projects, ideally for trend‑led, culturally switched‑on brands
• You've taken projects from concept to completion and carried the responsibility for them
• Your SketchUp is strong, and Vectorworks would be a real advantage
• You have an interior designer's instincts: a genuine feel for space, materials, and detailing, not just the ability to model it
• You can read creative direction and develop it into fully resolved design solutions
• You're confident with clients and contractors, and comfortable being the person they call
• You watch what's happening in fashion, streetwear, and retail culture, and you know how that translates into physical space
• You'd rather be in a collaborative, entrepreneurial studio where you're trusted to get on with it than in a process
• You want to bring others on while staying close to the work yourself

Why This One

Studios this size with a client list this good don't come up often. Direct access to the people making the decisions, a strong pipeline of fashion retail work, and a real say in how a growing studio evolves. If you love the culture as much as the craft, want your name on stores people actually talk about, and are ready to lead rather than sit in a queue, this one's worth a conversation.
