Back-End Developer (m/f/x) @ E-Mobility Startup

YOUR MISSION

Join Aampere, a seed-stage, VC-backed startup redefining the European market for used electric vehicles. Since our launch, we’ve enabled EV owners to sell their cars quickly and seamlessly within 48 hours, while giving dealers across Europe access to previously untapped customer segments.

Our team comes from the German startup ecosystem, with experience at Autarc, Limehome, Cardino, Wemolo, Alasco, Porsche, and Mercedes.

Backend Development & API Ownership: You build and operate scalable backend services and APIs using TypeScript and Nest.js. You think in end-to-end systems and make sure our services are stable, maintainable, and production-ready.

Architecture & Scalability: You design clean, scalable backend architectures and make pragmatic technical decisions that balance speed with long-term maintainability.

Cloud Infrastructure & Operations: You work with AWS services such as S3, EC2, RDS, and Lambda and help ensure that our systems run reliably, including in production.

CI/CD & Engineering Excellence: You see CI/CD not just as deployment mechanics, but as a lever for quality and speed. You work with pipelines covering testing, linting, builds, deployments, and rollbacks, and help make our delivery processes more robust over time.

Cross-functional Collaboration: You work closely with Product, Sales, and the rest of the engineering team to ship features quickly and reliably, and to build technical solutions with real business impact.

Ownership & Technical Direction: As part of a small team currently made up of three engineers, you take real ownership of the systems you build and actively contribute to the technical evolution of our platform.
