Software Engineer – AI/ML

With over 20,000 customers, Crewmeister is one of the fastest-growing workforce management software providers in Germany. Our success is driven by great products, strong teamwork, and people who are passionate about building exceptional software.

As part of the ATOSS Group, we combine the agility and ownership of a scale-up with the stability and resources of a leading software company.

AI is transforming how software is built, and we're investing in engineers who can help shape that future. We believe the next generation of software development will combine strong engineering fundamentals with AI-powered workflows, tools, and product capabilities.

If you're excited about building scalable backend systems while pushing the boundaries of AI-enabled product development, we'd love to hear from you.

This role is designed for experienced software engineers whose foundation is in backend development, distributed systems, and cloud-native applications. We are looking for engineers who have already gained hands-on experience with AI-powered applications, LLMs, AI agents, or retrieval-based systems in a professional setting. However, this is not a machine learning research or AI specialist role. Your primary focus will be designing, building, and operating reliable, scalable, and observable services that enable AI-powered functionality at enterprise scale.

Location: Bangalore (Whitefield, ITPL)

We operate in a hybrid work model with a minimum of 50% office attendance. To support onboarding, collaboration, and team integration, new team members are expected to work from our Bangalore office in Whitefield (ITPL) on a daily basis during their first six months. Following the onboarding period, the role transitions to our standard hybrid working model.
