Frontend Tech Lead We build and operate Connect, a SaaS platform for the beauty & wellness industry that helps entrepreneurs run their businesses more effectively. Our web products are used daily by tens of thousands of people across 13 European countries. Our teams own their areas end-to-end — from initial idea and design through deployment and operations. We focus on writing maintainable, scalable code while balancing legacy and modern technologies, and we encourage engineers to experiment, learn from mistakes, and improve our systems continuously. As Frontend Tech Lead, you sit at the intersection of technical leadership and people leadership. Our Frontend Stack The frontend stack is a mix of legacy and modern technologies. At the same time, the team is actively migrating toward a more modern React and TypeScript architecture, delivered through a gradual, page-by-page and feature-by-feature transition. Most new development happens in the modern React/TypeScript stack — React Query, Storybook, Jest, Cypress — while some work still involves the legacy Backbone codebase and the integration layer between old and new. Lead the Frontend Guild Make the guild a space engineers genuinely want to participate in — one that surfaces real problems, shares knowledge, and produces outputs (standards, patterns, tooling choices, ADRs) that teams actually use. Treat the guild as your most powerful lever — when it's working well, it multiplies your impact far beyond what you could achieve alone. Set technical direction and maintain quality Own the frontend technical direction for your vertical. Define what "healthy" looks like for frontend systems — instrumentation standards, alerting principles,



SLO patterns — so reliability is a first-class concern, not an afterthought. Actively mentor engineers in your vertical, helping them grow their technical scope and develop the habit of thinking beyond their immediate team. You're not downstream of product direction — you help shape it. 10+ years of software development experience, with deep expertise in modern web frontend technologies and a track record of operating across teams and codebases — not just within one. You know what it takes to define standards that engineers actually follow, and you understand that the quality of your relationships is often what determines whether your architectural agenda lands or not. Excellent English communication skills — you can articulate complex technical ideas clearly to engineers, designers, and non-technical partners alike. Frontend observability experience (Datadog, error tracking, monitoring, performance metrics, web vitals). You've experimented with AI in frontend projects and have clear opinions about where it creates real value — in the product, in the workflow, or both. A full-stack mindset: you may not write backend code day-to-day, but you understand how frontend and backend communicate and can reason about architectural decisions that span the stack. We're the industry's smartest salon management software, all connected to Europe's leading bookings platform, working with over 50,000 salon partners across 13 countries, processing over 8 million bookings every month. We're on an exciting journey to digitally revolutionise the hair and beauty community. 28-days holiday, plus bank holidays All qualified applicants will receive consideration without regard to their condition.
