At osapiens, more than 550 talented minds unite around one mission: enabling sustainable growth for businesses worldwide. Founded in 2018 and headquartered in Mannheim, Germany, we have built the AI-driven osapiens HUB - a multi-tenant platform hosting 26 enterprise-grade solutions designed for cross-company collaboration, automation, and compliance. With offices across Europe and the US, we are shaping the future of scalable and secure business technology. Why this role matters As we scale our platform and product landscape, the need for shared foundations, consistent architecture, and efficient developer workflows becomes critical. This role ensures that teams are not solving the same problems repeatedly, but instead build on well-designed, reusable solutions. You will play a key role in connecting teams, identifying common patterns, and turning them into scalable platform capabilities. Your work directly impacts engineering velocity, system quality, and long-term maintainability across the organization and beyond. This position follows a hybrid work model with a requirement to be in the office three times per week.
