About the Role
At LeasingMarkt.de, we connect customers and dealers to make car leasing more accessible, transparent, and efficient. As Germany’s #1 leasing platform, with over 1,000 partner dealerships and nearly 2 million users across the DACH region and the Netherlands, we are driving innovation in the mobility space. We are looking for a Senior Software Engineer / AI Enabler to join our high-performance team, ideally at our Düsseldorf office.
In this role, you will be crucial in designing and developing robust, scalable applications that power one of Europe's largest automotive leasing marketplaces. You will collaborate with a cross-functional team to build and evolve architecturally sound, maintainable solutions with long-term impact. You will help shape technical direction while elevating software quality and stability across the platform.
What you’ll do:
- Join one of our builders’ teams to build great products loved by our customers.
- Apply an AI-first mindset to every phase of you-build-it-you-run-it: from design and coding to testing, deployment, and operations.
- Work hands-on in real product codebases (for example TypeScript/Node/Next.js or Java/Spring), using GenAI tools to accelerate development, improve quality, and simplify existing systems.
- Build and evolve AI-powered internal tools and workflows (assistants for coding, reviews, documentation, testing) that engineers across AutoScout24 can rely on every day.
- Act as a multiplier and culture driver: coach teams on effective GenAI usage, share patterns and anti-patterns, and help establish AI-first ways of working across our engineering organization.
- Experiment, measure, and improve: run small, data-informed experiments with teams, learn what works in our context, and turn successful approaches into repeatable standards and playbooks.
What you’ll bring:
- Experience leveraging AI and Generative AI (GenAI) to enhance engineering productivity — including code generation, debugging, reviews, documentation, and decision support — with a proactive mindset toward adopting tools that streamline development and drive innovation.
- Deep, hands-on experience building production systems (at least 5 years), ideally with PHP and Laravel as well as TypeScript/Node.js/Next.js on AWS, Azure, or GCP.
- Demonstrated personal excellence in using GenAI coding tools (for example GitHub Copilot, ChatGPT, Claude Code, Cursor, OpenAI Codex) to significantly improve your own development speed and quality: code generation, refactoring, debugging, tests, and documentation.
- Experience integrating LLM APIs (such as OpenAI, Anthropic, Azure OpenAI, Vertex AI or similar) into applications or internal tools.
- Strong communication and influencing skills: you can introduce new tools and practices, align stakeholders, handle skepticism, and iterate based on feedback.
- A curious, growth-oriented mindset: you actively seek out new practices and tools, you are comfortable learning in public, and you help others do the same.
- A pragmatic view of GenAI: you understand its limitations and risks and know how to put guardrails in place (reviews, tests, policies) to keep usage safe, compliant, and sustainable at scale.
- Experience with performance optimization, caching strategies, and system observability is a plus.
