Full Stack Developer

Location: London, England, United Kingdom

Department: Industrial Design

About the Team

You'll be joining the Industrial Design team — a cross-functional group of Industrial Designers, Experience Designers, and Creative Technologists working from our design studio in Kings Cross. This isn’t a traditional software development role; you might have a background in front-end engineering, creative coding, physical computing, or something else entirely.

This isn't about building websites. It's about prototyping the future of how our hardware and software connect and behave as one - creating new interfaces and experiences that bridge the physical and digital.

In addition to your core skills, we're interested in your superpowers, both in and out of work, and how they might contribute to what we're building.

What You'll Do

• Build and iterate on functional prototypes that define how our product ecosystem behaves — moving quickly from concept to working experience.
• Partner with the Design team to build new interfaces and experiences, including the APIs and hardware integrations (BLE, Haptics, Sensors) that connect our hardware and software.
• Build and own internal tools that make the design team faster and more capable — if a workflow can be better, you'll build the thing that makes it so.
• Take ownership of our internal prototype deployment infrastructure, ensuring we can ship prototypes across the company with ease.
• Research and de-risk complex features — providing the technical expertise that helps the team commit to the right ideas with confidence.
• Drive technical excellence across the codebase, making pragmatic decisions that balance long-term stability with the need to move fast.

What We're Looking For

• Full-stack experience with strong front-end craft — systems thinking and data flow, but also an eye for design, motion, and interaction detail. Great taste.
• Experience integrating LLMs into products, whether that's AI-powered prototyping, agent systems, or orchestration. MCP experience is a plus.
• Deep expertise in at least one programming language (JavaScript, Kotlin, Swift, or similar). We expect you'll use AI tools to accelerate your work — but there's no substitute for genuine fluency.
• Creative instincts. This isn't a role where you'll be handed a PRD to implement — you'll be ideating and inventing as part of the process.
• Pragmatism over polish. The experiences you create will feel like the real thing, but we need to get there fast. The best prototype is the one that validates the idea quickest.
• Our mobile products are built on Android - experience prototyping on-device or using web technologies to achieve the same result is a plus.
• Honesty, transparency, and empathy. At times you'll be heads-down solving a deep problem solo; other times you'll be brainstorming and collaborating with designers and creative technologists.

How We Work

• We build better tech by moving fast. That speed demands direct collaboration and shared creative energy. We believe the best work happens when we're together.

• Location: London (Kings Cross & Farringdon offices).

• Working Pattern: This is a full-time, in-office role (5 days a week). We move fast, and that means being physically present. We design flexibility around personal needs, but we focus on the magic that sparks when we’re all in the same room.

• Commute: We ask that you live within a 60-minute commute of your home office location.
