Senior Java Software Engineer (Java, Spring, AWS) – Robotics & AI

A fast-growing robotics and AI startup is transforming how industrial robots operate within dynamic warehouse environments. The company specialises in high-throughput palletising and advanced logistics automation, building distributed, cloud-native systems where reliability, scalability and performance are mission-critical.
