Back-End Developer; m​/f​/x @ E-Mobility Startup

Position: Back-End Developer (m/f/x) @ E-Mobility Startup Location: Germany 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, Greenforce, Cardino, Wemolo, Remberg, Alasco, Porsche, Mercedes, and KPMG.

Responsibilities

• Backend Development & API Ownership: You build and operate scalable backend services and APIs using Type Script 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.

Must Have

• Backend

Experience: You have 2-4 years of experience building production backend systems and APIs, and a strong understanding of clean, scalable software architecture.

• Backend Engineering Fundamentals: You are confident building production-grade backend systems with Type Script and Nest.js. You bring hands-on experience with AWS, relational databases such as Postgre

SQL, REST API design, and Docker, and understand how to build, run, debug, and maintain reliable services in production.

• AI-native Development: You use AI tools effectively to accelerate software development - from prompting and validating generated code to debugging AI-generated implementations.
• Startup Mentality: You make pragmatic decisions, are comfortable with shifting priorities, and enjoy building in a dynamic startup environment.
• Communication: You communicate clearly, transparently, and effectively in English.

Nice to Have

• Asynchronous & Event-driven Systems: You have experience with asynchronous systems, queues, workers, or event-driven architectures.
• Full-stack Perspective: You bring experience with Next.js or full-stack development.
• Additional

Languages: You have worked with Python, Go, or other programming languages.

• Early-stage

Experience: You know what it means to work in an early-stage startup and feel comfortable in small, high-impact teams.

• Collaboration & Mentoring: You give constructive feedback in code reviews, enjoy improving engineering processes, and support other engineers in their development.
• German

Skills: You ideally also speak German. Why AAMPERE?

• Start-up environment: make a difference every day and electrify the world together with us
• Motivated team: seize the opportunity and learn from the best
• Flexible working hours and home office option: the result is what counts for us
• Urban Sports Club & €58 ticket: healthy team, happy team
• Late dinner at the office: If you’re working past 8 pm, we’ll cover your dinner via Uber Eats.
• Offsite: so far we've been to Lake Maggiore, the Alps and Tegernsee, what's next?
• Living in the Werksviertel: In the adjacent co-living space, you have the option to rent a private room independently - right next to the Aampere office and with a view of the Ferris wheel.

Regardless of your background, origin or gender identity - what matters to us is who you are as a person. We promote a culture of respect and cooperation in which every voice is heard, personal development is possible and appreciation is paramount. #J-18808-Ljbffr Apply tot his job Apply To this Job
