Software & Applied AI Engineer
Braşov
Braşov, Romania

You are a software engineer with solid experience in building reliable services and you want to take the next step into the world of AI? Then this role at GuideStream might be a perfect fit. As a Software & Applied AI Engineer (Remote, Romania) you will work in a small, experienced team on real customer solutions – from integrating modern AI services into existing system landscapes to developing new, cloud-based backend components. Occasionally, you will also contribute to frontend development, e. g. for Human in the loop interfaces.

GuideStream is an AI consulting and services company based in Grünwald (Munich area), working with customers primarily in Germany and Switzerland. We combine strong business understanding with deep technical expertise to help our clients navigate their digital transformation.

Our focus is on AI strategy & transformation and software development services, especially for industries such as manufacturing, finance and wholesaler. We work in small teams instead of a high-volume staffing model: our clients trust us as long-term partners, not just as a delivery factory.

What sets us apart is a pragmatic, solution-oriented mindset: we focus on real business value, lean processes and high-quality engineering. If you enjoy responsibility, clean engineering and working closely with clients, GuideStream offers you a place to grow and have real impact.
