About Aampere

Join Aampere, a seed-stage, VC-backed startup redefining the European market for used electric vehicles. The ambition is no smaller than becoming the #1 EV Resale Platform in Europe. We are a fast-paced 25 people startup with a growing engineering team. That means you don't wait for tickets. You understand a problem, concept the solution, and get it done.

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

Your Mission

Backend Engineering: You design, build and maintain the services and RESTful APIs behind our platform with TypeScript, Nest.js, MikroORM and PostgreSQL. You own data models, third-party integrations and async workflows built on BullMQ and AWS SQS, including background jobs, retries and scheduled sync.
Architecture & Scalability: You make the calls on how our systems are structured, how they scale and how they stay maintainable as we grow. Performance, data integrity and clean interfaces are your responsibility.
Infrastructure & Deployment: You ship to production on AWS. If something breaks, you find out why and fix it at the root.
Full-Stack When Needed: You're comfortable working in our Next.js, React and Tailwind frontend to ship a feature end to end, even if the backend is where you spend most of your time.
Business-driven Engineering: You understand what you're building and why. You connect technical decisions to outcomes like conversion, speed and automation, and act without being asked.
AI-native Development: You use AI tools like Cursor and Claude Code as a core part of your workflow, as a real lever for speed and quality.

What you bring

Experience: 5+ years building production systems, with a clear focus on backend.
Backend Stack: You have strong skills in TypeScript, Nest.js, PostgreSQL and Docker, plus hands-on experience with job queues and messaging (BullMQ/Redis, SQS or similar). You design solid schemas, write efficient queries, build reliable, idempotent consumers and ship APIs.
Infra: Some experience with AWS and GitLab CI/CD.
Frontend: Working knowledge of Next.js, React and Tailwind. You don't need to be a UI specialist, but you ship frontend changes when a feature needs them.
Ownership: You solve problems end to end, from architecture to implementation, deployment and iteration. You start things without being told and see them through.
Communication: Clear communicator in English. German is a plus.

Why Aampere?

Start-up environment: Make a difference every day and electrify the world together with us.
Real ownership: You're engineer #5. What you build ships to real users fast.
Urban Sports Club &  job-ticket: Healthy team, happy team.
Tech: Apple or Windows, we provide your laptop. You choose what you work best with.
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.

Aampere isn't for you if...

...you want to work mostly remote. We believe the best ideas happen when people are in the same room. That is why you are in our office at least four days a week.

...you want to walk into ready-made processes and structures. A lot of that does not exist here yet. We are looking for people who build structures and processes, not people who administer them.

...you need a finished plan before you start. Seed stage means a lot is unclear and changes week to week. You have to be comfortable making decisions in the dark and correcting course as you go.

...you want to stay in your lane. "That is not my job" is not a thing here. You jump in where it matters, even when it sits outside your job description.
...you want a classic 9-to-5. We are building something big, and that does not happen on the side. The people here want to go all in, not just put in the time.

How we work

Three values, not slogans on a wall but how we work, hire, and grow every day:

Aaudacity. We are brave enough to take risks, fast enough to not half-ass it.
Aambition to grow. We are committed to grow, as individuals and as a company.
Aampact over Hierarchy. The best idea wins, no matter who brings it. Titles don't decide arguments here.

A few words at the end

Apply now! We look forward to receiving your informal application - we will discuss everything else together.

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.
