(Senior) Full-stack Engineer (all genders) | Climate Tech

Intro

Carbmee empowers organizations worldwide to systematically measure, manage, and reduce their carbon footprint. Backed by a recent €20M Series A funding from top VCs, we are one of the fastest-growing companies in European tech with offices in Berlin and Munich - proud to be at the forefront of climate innovation. Our platform leverages AI with millions of transactional data points to help enterprise customers tackle their most complex emissions challenges - far beyond compliance.

Your Role & Mission - We're looking for a pragmatic and curious Fullstack Engineer who loves solving problems end-to-end. You should feel at home working across the stack - frontend, backend and infrastructure - and bring a flexible, product-driven mindset.
This role is perfect for generalists who want to build real things, move fast and continuously ask: How is the customer actually using this? We care about strong fundamentals - but even more about people who can ship, communicate and think like owners.
Our Hiring Process - Our Engineering team is growing fast and we are seeking talented Software Engineers across different backgrounds and experience levels. We know that each level of experience involves its own set of challenges and expectations, and the hiring process is tailored accordingly to evaluate all candidates effectively. That means each interview step is focused on assessing both technical and soft skills across our engineering competency framework. Chosen candidates will receive an offer package that aligns with their mid-level or senior level of experience, including additional perks and benefits.

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

• 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

• 5-8 years of hands-on experience in fullstack or web development in B2B Saas

• Proficiency in JavaScript/TypeScript, ideally with React and/or Next.js

• Experience building backend services in Node.js or Python

• Understanding of relational databases (we use PostgreSQL)

• Exposure to cloud infrastructure, preferably AWS

• Someone who thrives in ambiguity and fast-paced environments

• Strong communicator who enjoys working across functions and collaborating with product

• You are passionate about business sustainability, carbon emissions management, and climate tech in alignment with Carbmee’s mission and vision

• You are excited to join our diverse and international team in Berlin or Munich

Bonus points:

• You’ve worked on technically interesting systems - think real-time processing, distributed systems, event-driven architecture, performance optimization or scalable APIs

• You’re someone who gets things done and figures things out

• You've worked in small teams or startups where ownership was key

Don't feel like you meet all the criteria? We get it: confidence can sometimes hold us back from applying for a job. We'll let you in on a little secret: there's no such thing as a 'perfect' candidate. Carbmee is a place where everyone can grow. So however you identify and whatever background you bring with you, please apply if this is a role that would make you excited to come into work on a Monday morning.
