The job, in the employer's words
Your mission
As Engineering Manager at Cosuno, you will lead a team of full stack engineers while staying deeply hands-on: you'll spend 60–80% of your time coding, reviewing, and shaping the architecture alongside your team. You are the kind of leader who elevates a team by example — writing code that sets the bar, and building an environment where great engineers do their best work.
Your mission might include:
Leading a team of full stack and AI/ML engineers: coaching, regular 1:1s, growth plans, and hiring — while shipping product yourself every week.
Owning the delivery and technical quality of your team's roadmap, working closely with your Product Manager to plan, de-risk, and execute.
Contributing hands-on across our TypeScript stack (React + Node), from designing features to reviewing pull requests and tackling the hard problems yourself.
Raising the team's technical bar through code reviews, architectural guidance, and best practices — including driving the adoption of AI-assisted engineering workflows.
Partnering with engineering leadership on team topology, processes, and the technical direction of our platform.
How We Build: Our Engineering Culture
We believe in a calm, collaborative, and productive engineering environment. We trust our engineers and give them the autonomy to do their best work. Our approach includes:
Agile & Fast-Paced: We practice trunk-based development with daily releases to get value into our users' hands quickly.
Quality by Default: We maintain a comprehensive Cypress E2E test suite and enforce strict typing, linting, and formatting rules to keep our codebase clean and maintainable.
DevOps Mindset: Our well-oiled CI/CD pipeline deploys to AWS via Kubernetes, with our entire infrastructure managed as code using Terraform.
Collaboration & Transparency: We value open discussion, constructive code reviews, and a culture where the best idea wins, regardless of who it comes from.
Your profile
We're looking for a player-coach: a strong engineer who leads people without giving up the keyboard. You'll be a great fit if you have:
Extensive experience (typically 7+ years) in software engineering, with a proven track record of delivering complex, scalable web applications.
Strong expertise in our core technologies (TypeScript, Node.js, React) and the ability to reason about the entire stack, from the database to the browser — and you still use it daily.
Leadership experience — whether as an Engineering Manager or team lead with direct reports, or as a senior tech lead who has mentored engineers, led projects, and shaped how a team works.
A genuine desire to keep coding: this role is 60–80% hands-on by design, and that's what excites you about it.
A passion for growing people. You find joy in helping other engineers develop, in giving honest feedback, and in building a healthy, high-performing team.
Bonus, not required: a good understanding of building LLM-based applications or ML algorithms — your team includes AI/ML engineers, and being able to follow their work helps, though you won't need to be the expert.
Excellent communication skills in English, with the ability to articulate complex technical concepts to both technical and non-technical audiences.
Why us
Competitive Compensation: A competitive salary above the market average.
Work-Life Balance: Choose to work 100% remotely or from our modern office in Berlin. We offer flexible working hours to fit your life.
Top-Notch Equipment: A new MacBook Pro to ensure you have the best tools for the job.
A Great Team: Regular company off-sites and team events that connect us as people, not just colleagues.
Job Security: A permanent contract in a stable, well-funded company.
