Job Description:

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. Your job is not to make every decision, but to create the conditions in which good decisions get made consistently — across teams, across codebases, and across the organisation. The frontend stack is a mix of legacy and modern technologies. The application originally grew as a Backbone-based product, served through Node/Express with EJS templates, and there are still important areas of the product that work this way today. 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. The migration itself is one of the key technical threads you'll help shape and drive forward.

Job Responsibility:

  • Lead the Frontend Guild
  • Set technical direction and maintain quality
  • Build relationships and grow the people around you
  • Bridge engineering and the wider organisation

Requirements:

  • 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 have set technical direction before. 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
  • You are a natural builder of trust. You invest in understanding the people and teams you work with — their strengths, their constraints, their context — and you use that understanding to lead more effectively, not to manage more tightly
  • You adapt your leadership style to what the situation requires. When teams are engaged and capable, you focus on enabling and elevating. When they are not, you roll up your sleeves, build the relationship, and earn the right to lead
  • You can hold technical depth and organisational breadth at the same time. You are credible in an architectural review and equally comfortable in a conversation with an Engineering Manager or a product stakeholder
  • Excellent English communication skills — you can articulate complex technical ideas clearly to engineers, designers, and non-technical partners alike
  • You lead by example. The code you write and the decisions you make reflect the standards you set for others

Nice to have:

  • Frontend observability experience (Datadog, error tracking, monitoring, performance metrics, web vitals)
  • Experience with mobile-first design, atomic design principles, and progressive enhancement for responsive applications
  • 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
What we offer:
  • 28-days holiday, plus bank holidays
  • Monthly €40 Treatwell vouchers so you can treat yourself too
  • Mental health support through our partnership with Plumm
  • Growth funds for you to develop and grow with your team
