Senior Engineering Manager - Remote (DE, UK, PT, ES)

⭐ You'll thrive in this role if you:

• Bring 8+ years of experience in software engineering with 3+ years managing engineering teams.
• Have managed 8 or more engineers as your primary job. You have run sprints, done performance reviews, hired, fired, promoted, and coached people through career transitions.
• Know sprint mechanics cold. You have opinions on planning length, story sizing, retro formats, refinement cadence. You can walk into a team that is running sprints badly and diagnose it in one cycle.
• Are product-adjacent. You sit with PMs, you ask about customer problems, you understand why the roadmap looks the way it does. You do not treat product as "the people who give us tickets".
• Care about people careers as much as delivery. You have specific examples of engineers you helped grow: from mid to senior, from IC to lead, from stuck to unstuck. You give feedback fast, direct, and kind.
• Have designed and owned complex Systems before. You don’t need to write code frequently, but you have owned Systems in the past. You have architecture and system design experience, and can hold a real conversation about event-driven systems, deploy failures, database performance or infrastructure cost, without being blocked behind your technical peers.
• Are calm in a fast-paced environment. Cozero ships fast. Incidents happen. Scope changes. You don’t create additional heat; you absorb it and reset the team.
• Communicate in writing first. Weekly written updates, structured notes, incident retros. Async by default, but you advocate for a genuine outspoken culture where people have more ad-hoc calls than fixed-schedule meetings.
• Are comfortable working remotely across a mostly-EU team. You know how to build psychological safety without hallway conversations.
• AI champion. You have worked and successfully thrived in a pre-AI era, but you’re comfortable with AI-assisted engineering tooling (Claude, Cursor, Copilot) and interested in raising the team's fluency here.
