seamflow - Front End Design Engineer

• We care far more about taste and engineering strength than about matching a list of tools. If you're excellent, we'll hire you whether you've spent the last three years in React, Svelte, Vue or something we haven't heard of. Our stack is learnable in a fortnight. Judgement, craft and speed are not. • What we're actually screening for: • You've designed and built an interface that real people used every day. Not a Dribbble shot, not a component library nobody adopted. Something that shipped, got used, and got better. • You have taste, and you can defend it. Typography, spacing, motion, hierarchy. You notice when something is a few pixels off and you can explain why it matters. • You build the whole thing. Design, frontend, the state and data it sits on. You don't hand the code to someone else once the Figma is done, and you don't hand the design to someone else once the code is. • You can design for density. Expert users, complex workflows, hundreds of fields on a screen. Making that clear is much harder than making a landing page beautiful. • You go to the source. You'll watch a technical reviewer work through a real file, and you'll design for what they actually do rather than what the process diagram says. • design engineering or front-end roles at somewhere like Linear, Vercel, Notion or Figma, a design system you built and maintained, work on interfaces where people review or correct AI output, founder or ex-founder, founding team experience, EF / YC / Antler, early or stealth-stage startup. • This is probably not for you if • You want a strict boundary between work and life. We run one of the most ambitious startup cultures in Europe: fast paced, extremely high ownership, and in person in Shoreditch. • You want a well-defined ticket handed to you each morning. • You want to specialise narrowly and stay in your lane. • Real equity, and compensation that reflects a high bar • Genuine ownership of product surface area from day one, with the founders in the room • Relocation support and visa sponsorship, handled properly • Lunch and dinner covered, 24/7 gym access, and any tool that makes you faster • A small team with high standards, high trust, and no politics • If this sounds like your kind of problem, apply. A short note on the hardest thing you've built goes further with us than a polished CV.
