About the role

You will lead a frontend squad by hands-on coding with AI agents, setting technical standards, and managing sprint delivery. You are responsible for the operational health of your domain, including monitoring, security, and mentoring team members.

What they look for

React TypeScript Node.js BFF patterns REST API Playwright Jest Next.js AWS Technical leadership Mentoring Agile Frontend development Agentic development Cloud environments SaaS

Requirements

The role requires 6+ years of experience in production frontend development with deep expertise in React and TypeScript. Candidates must demonstrate proficiency in agentic workflows, strong communication skills, and the ability to lead technical decisions in an agile environment.

Benefits

Flexible working hours Paid sick leave Company events Celebrations

Full description

  • Agentic development as your primary workflow: daily, fluent use of Claude Code, OpenCode or an equivalent harness on production code, including multi-step tasks and parallel sessions.
  • Evidence you have configured the harness, not only used it: agent instructions, subagents, MCP servers, tool permissions, CI checks for agent output.
  • 6+ years building production frontend applications, with deep React and advanced TypeScript.
  • Critical review of generated code — knowing when to accept, correct or reject, and why.
  • Node.js and BFF patterns, REST API design, automated testing with Playwright and Jest.
  • Technical leadership without needing a manager title behind you: mentoring, setting standards, owning a codebase area, leading a squad through decisions.
  • Ownership of features from ticket to production, with a quality and reliability mindset.
  • Clear written communication and autonomy in a remote-first, agile team; English at C1.

Nice to have

  • Experience with Next.js and server-side rendering
  • Familiarity with AWS or other cloud environments
  • Experience in subscription, billing or payments domains

Responsibilities:• Ship code yourself — stay hands-on in React and TypeScript, take real tickets, and drive them with agents rather than supervising from a distance.

  • Own the agent harness for frontend — Claude Code and OpenCode configuration, agent instruction files, subagents, MCP servers, hooks and permissions. Treat "the agent could not figure this out" as a signal about our codebase and context, not only about the agent.
  • Raise the team’s agentic ceiling — pair, demo, and improve the docs, conventions, tests and tooling agents work from, so the whole squad ships faster and not only you.
  • Stay the engineer in the loop — you own correctness, design quality and security of what the group merges, whoever or whatever wrote the first draft. Set the review bar for agent-written code and back it with CI gates.
  • Hold delivery for the frontend scope of your squad: sprint commitments, estimates, and the trade-off calls between speed and quality.
  • Run the group day to day — 1:1s, standups, unblocking. Light-touch and temporary by design; you are not being hired to write process.
  • Own what you ship: launch with dashboards and alerts, monitor, and take part in the operational health of your squad’s domain.
  • Take a structured handover from our Lead Frontend Engineer before the leave starts, and hand it back cleanly on her return.
  • Flexible working hours and form of employment;
  • 100 % paid sick leave within the agreed limits;
  • Events, celebrations
  • Work with an international team of well - rounded experts in Amsterdam (HQ), Poznan, Manila, NYC. 16 nationalities and counting!
  • Work on unique, market-leading, SaaS products, with clients all over the world: Europe, Asia, Americas;
  • Work closely with people who value diversity, hard work, friendly relationships and love their jobs, and get all together to the next level!
  • Join a company where engineering and business teams work as true partners, shaping the future of subscriber management technology.
  • Be part of a culture that values ownership, impact, and learning, with AI at the heart of our innovation strategy.
