About the role

Key responsibilities & impact

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
Raise the team’s agentic ceiling — pair, demo, and improve the docs, conventions, tests and tooling agents work from
Stay the engineer in the loop — own correctness, design quality and security of what the group merges; set the review bar for agent-written code and back it with CI gates
Hold delivery for the frontend scope of the squad: sprint commitments, estimates, and trade-off decisions between speed and quality
Run the group day to day — 1:1s, standups, and unblocking
Own what you ship: launch with dashboards and alerts, monitor, and take part in the operational health of the squad’s domain
Take a structured handover from the Lead Frontend Engineer before the leave starts, and hand it back cleanly on her return

Requirements

What you’ll need

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
Nice to have: Familiarity with AWS or other cloud environments
Nice to have: Experience in subscription, billing or payments domains
