Overview

We are launching an EV leasing business in Germany and need a Senior Full‑Stack Software Engineer to build it from the ground up. You will be one of two engineers, working directly with the country General Manager to rapidly build and validate our product for the German market. This role is perfect for a full‑stack developer who is excited by the challenge of quickly shipping minimum viable solutions and directly enabling business growth.

What you’ll do

• Build Fast, Deliver Impact.
• You will pioneer the engineering effort for a new market within a small, resource‑constrained, cross‑functional team.
• Your primary measure of success will be market validation and speed‑to‑launch, not technical perfection.
• You must be comfortable developing long‑term temporary tools designed to validate the market and replaced on a 1–2 year horizon if successful.
• You will work proactively and independently, translating high‑level business goals into prioritized, shippable technical tasks.
• You will make critical trade‑offs between security/maintainability and speed/investment, particularly when dealing with PII and payments.

What you’ll need

• Native C2 German and Professional English fluency.
• Extensive experience as a Senior Full‑Stack Developer focused on speed and business enablement.
• Deep expertise in TypeScript, React, Node.js, and SQL/noSQL databases.
• Proven experience delivering prototypes or MVPs that were later deprecated or rebuilt, demonstrating comfort with building transient solutions.
• Strong understanding of modern development workflows, including Git and CI/CD pipelines.
• Exceptional problem‑solving skills and the ability to work autonomously and proactively.
• Motivated by business success and rapid validation over building a permanent, polished codebase.
• Comfortable with the ambiguity inherent in a new market entry.
• Biased toward shipping minimum viable solutions rapidly.

What you’ll be doing

• Develop modern, responsive, and reusable frontends with React and TypeScript.
• Build fast, secure, and scalable backend services and APIs using Node.js, integrating with SQL and NoSQL databases and third‑party APIs.
• Deploy and maintain your own systems on cloud hosting providers.
• Engage in rapid prototyping, unit testing, and agile development cycles, using GenAI tooling where appropriate to accelerate delivery.
• Work in a paired environment as the senior engineer while adhering to technical guidelines provided remotely by our UK team.

Why you’ll love it here

• We value rapid validation and are open to talk with anyone who is a good fit, even if you don’t meet every requirement.
