Full-Stack Engineer (startup generalist)

About this role

We are seeking a Full-Stack Software Engineer to strengthen our engineering team. In this role you will help design, build, and ship new functionality across our stack: From back-end services and cloud infrastructure to the applications our customers rely on inside recycling plants.

This is a hands-on engineering role for someone who thinks end-to-end. You will take on real engineering challenges: reasoning through the logic, drafting the architecture, deciding how a solution should be deployed and served, and then implementing it. As a small, fast-moving startup, we need someone comfortable working across the full stack and able to own a challenge from idea to production, a true startup generalist.

Responsibilities

• Take engineering challenges end-to-end - define the logic, draft the architecture, decide how the solution is deployed and served, and implement it.


• Design, build, and deploy back-end services and APIs on Google Cloud, using Cloud Run, VMs and Firebase Functions.


• Model, store, and serve data reliably with Firebase and NoSQL databases.


• Write clean, maintainable Python across services and internal tooling.


• Containerize and ship applications with Docker, using Git/GitHub for version control.


• Contribute to front-end applications (React, and potentially Swift-iOS).


• Maintain high standards for code quality, scalability, and reliability in production environments.

Requirements

• A university degree in computer science, computer engineering, or related field.


• Several years of software engineering experience across the stack.


• Strong proficiency in Python and solid general software engineering fundamentals.


• Proven ability to solve engineering challenges end-to-end, from logic and architecture through to deployment and serving.


• Experience with cloud and serverless technologies (Google Cloud, Cloud Run, Firebase Functions).


• Experience with NoSQL databases (Firebase).


• Experience with Docker and Git/GitHub.


• Comfortable working autonomously in a fast-paced startup environment with high ownership.


• Strong communication and collaboration skills.

Nice to Have

• Front-end development experience with React.


• iOS development experience with Swift.


• Experience with edge systems: Python on Linux, containerized deployments, and on-device trade-offs.


• Familiarity with industrial, IoT, or real-time monitoring systems.


• German language skills.
