About the role

We are looking for an Engineering Manager, Frontend to lead our frontend engineering group while our Lead Frontend Engineer is on maternity leave. This is a fixed-term cover role with a real mandate: you keep the team shipping, you stay in the code, and you own how far we can push coding agents.

The group works inside cross-functional squads, primarily our Subscriber Experience Squad (SXP), which owns the full subscriber lifecycle from checkout to account management. What the frontend ships here moves conversion, retention and churn directly.

AI is our foundation.

We are an AI-first company, and for this role that is the job rather than a bonus. We expect you to already drive an agentic harness - Claude Code, OpenCode or equivalent - as your primary way of writing software, and to make the rest of the team faster at it than they are today. If your use of AI stops at autocomplete, this is not the right role for you.

We are open to this being your first formal leadership role. We would rather hire a strong senior engineer who leads by building than a manager who has stopped writing code.

Your mission

Keep Cleeng’s frontend shipping at full speed while our lead is on leave, and hand the team back more capable with coding agents than you found it.

Your 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.

The ideal candidate will have the following Competencies

• 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.
