[Hiring] Lead Frontend Engineer @Infinni Innovations S.A.

Role Description

This is a frontend lead who sits in Design, not Engineering. You’ll own how design becomes code at INFINNI. Today design reaches engineering the way it does almost everywhere: files, docs and threads that drift from each other and from what ships. AI made each of them faster to produce. It didn’t close the gaps between them. We’re changing that. Internally we call it Design Next: a new way for Design, Product and Engineering to go from idea to production, built around AI from the start. Code is the source of truth. Design tools are input, not the destination. Parts of it already run. Most of it is still to be built. You’ll be one of the few people building it, with a real say in how it works.

What you’ll own

• The frontend standards.
• The path to production.
• The agents and tooling.
• The quality bar.
• The design system, from the Design side.
• Teaching.

What good looks like

• An engineer builds a feature from Design’s work without asking a single question.
• Design-system violations get caught before review, not after release.
• Designers ship with confidence, because the guardrails are right.

Who you are

• You’re AI native.
• You care about design.
• You think in systems.
• You have opinions on where AI should decide and where it should only advise.
• You write decisions down.
• You’re comfortable owning something that isn’t built yet.

What you bring

• 7+ years in frontend, including 2+ as a tech lead.
• Hands-on experience designing and building AI agents and workflows.
• Advanced, daily use of AI coding tools (Claude Code or similar).
• Expert React and TypeScript, in strict mode.
• Strong Tailwind CSS and shadcn/ui.
• You’ve built or maintained a component library or design system.
• Testing across the stack.
• Accessibility in practice.
• Internationalisation at scale (i18next or similar).
• Performance work.
• Tooling.
• Git fluency.
• Fluent written and spoken English.

Nice to have

• Electron or desktop app experience.
• Deep knowledge of accessibility and internationalisation standards.
• Built internal dev tools, CLIs or codegen.
• SaaS, CRM or creator-economy products.
• Chinese or Spanish.

Benefits

• A seat in Design.
• A real 0-to-1 problem.
• Your standards become the system.
• A team that treats AI as a multiplier, not a buzzword.
• Competitive salary.
• Flexible hours.
• Yearly company offsite.
