Design Engineer

Zing Coach builds an AI-powered fitness coach. We partner with gyms, leisure operators, and fitness platforms to bring personalised training to their members. Our designer is moving on, so we're looking for someone who can both design the product and ship it in code.

Why this role exists

You'll be our only designer, which means you are the design team. You'll own everything from the product our gym partners use every day to the decks we pitch with. No handoffs, no design-by-committee: you design it, you build it, it ships.

What you'll do

• Own product design end to end, from flows and UI to interactive prototypes and polished, production-ready screens.
• Build what you design: implement UI in our React / Next.js codebase together with our frontend engineer, not just hand over Figma files.
• Design and ship B2B surfaces: our Partner Portal, admin tools, and white-label and branded experiences for gym partners.
• Own our design system end to end, from Figma Variables through tokens (Token Studio / Style Dictionary) to Tailwind in code.
• Keep our website, landing pages and web funnels fresh, and design sales and investor decks, in-app messages and email templates.
• Work closely with Product, Engineering and Commercial, and turn partner requirements into shippable designs quickly.

What we're looking for

• A portfolio of shipped digital products. We care about what you've built and how fast you learn, not years on your CV.
• Hands-on frontend skills: TypeScript, React, Next.js and Tailwind CSS. You can open a PR, not just a prototype.
• A track record of building and shipping prototypes fast (Framer, Lovable, Vercel, Figma or code) and making production UI changes yourself.
• Experience building or maintaining a design system with tokens bridging Figma and code.
• Comfortable using AI tools (Claude, Cursor and similar) to prototype and build fast, and you know the difference between a prototype and production code.
• Organised and autonomous: you can take a vague problem, plan your own work and come back with a solution quickly.
• Taste and storytelling: you know what great design looks like and can explain your decisions with clarity and conviction.

Who this role is not for

• You want to hand over Figma files and move on; here you take your designs into code.
• You need detailed briefs or structured processes; you'll often start from a vague problem.
• You only want to work on product UI; you'll also own our website, sales and investor decks.

What success looks like in your first months

• Our product, website and decks look noticeably sharper, and the team references your work.
• You ship changes to production yourself, without waiting on engineers.
• Engineers find your designs clear and easy to build, and enjoy working with you.

Details

• Fully remote
• Start: 1 December
