Developing software is one thing. Building software that remains scalable, secure, and maintainable for years requires craftsmanship.

At adesso, we develop software for organizations where technology is mission-critical. We build cloud-native applications, backend platforms, and integration solutions used daily by thousands of users. Increasingly, these systems also form the foundation for AI applications, intelligent automation, and the integration of Large Language Models (LLMs).

That is why we are looking for Software Engineers who look beyond just code. Engineers who enjoy contributing ideas regarding architecture, software quality, and the future of modern software development.

As a Senior Software Engineer, you design and develop modern backend solutions within complex enterprise environments. You work on cloud-native applications, microservices, and integration platforms where reliability, performance, and scalability are central.

You are not only responsible for writing high-quality code, but you also actively contribute ideas regarding architecture, software quality, and technical choices. Together with colleagues, you help clients realize sustainable solutions that last for years.

Additionally, you will increasingly work on backend services that unlock data for analytics, AI, and intelligent automation. In this way, you help build software that is ready for the future.
