(Senior) Full-stack Engineer | Climate Tech startup

Intro

Carbmee builds the System of Action for carbon and environmental data in the world's most complex industrial sectors: automotive, defense, heavy manufacturing. Backed by €20M Series A, growing fast out of Berlin and Munich.

We're looking for a Fullstack Engineer who treats the codebase like a product, not a ticket queue. You should be equally comfortable in React/Next.js, NestJS, Python, and PostgreSQL.

This is not a maintenance role. We're a small engineering team solving genuinely hard data and integration problems for enterprise customers who don't tolerate sloppy software. If you want to ship fast, own outcomes, and work with people who studied and worked at the top of their field, this is your kind of place.

Please note: at this stage we're not able to offer visa sponsorship. Candidates must already have the right to work in Germany.

Your tasks

• Build and ship end-to-end features across the stack (React/Next.js, NestJS, Python, PostgreSQL)
• Collaborate closely with product managers and designers to solve real customer problems
• Own your work - from idea to deployment and beyond
• Sit with product and customers directly: you're expected to have opinions on what we build, not just how
• Work on a service-oriented architecture deployed on AWS
• Bring your ideas, challenge assumptions, and shape our technical direction with the team
• (If senior) Mentor others and help us raise the engineering bar

Your profile

• CS degree from a top university: you've been trained to think rigorously about complex problems
• 3+ years shipping production B2B SaaS software, not just personal projects or bootcamp portfolios
• Deep proficiency in TypeScript/React and Node.js or Python
• Solid grasp of relational databases and cloud infra (AWS)
• Evidence of ownership: a side project, an OSS contribution, a system you built and are proud of: not just a job history
• You ask "why" before "how," and you've pushed back on a product decision before
• You are excited to join our diverse and international team in Munich

Benefits

• Unique & Powerful Mission: join a fast-growing and ambitious tech company that is shaping the future of carbon management and fighting climate change
• Compensation & Rewards: a steep learning curve and ownership from day one. We offer an attractive compensation package, including virtual stock options
• Health & Wellbeing: Urban Sports Club subscription to stay healthy & fit.1:1 coaching sessions with Nilohealth for your mental well-being.
• Flexible & Balanced: A hybrid setup with 3 days/week in our Munich office. Real collaboration time with the team, plus the flexibility to structure the rest of your week where you focus best.
• Team Culture: Our transparency, Humility, and Accountability values create a unique and supportive working environment. Be part of a multinational, motivated team that thinks work should be fun!
• Connection & Networking: Summer Offsite, Winter Party, and regular team events We give you plenty of opportunities to connect with people, strengthen cross-functional relationships, and boost collaboration
• Trust & Transparency: monthly All-Hands Meetings, weekly update newsletters, and Founders Q&As. We keep you informed on current company numbers and goals
