AI Backend Engineer (m/w/d)

Role summary This position is ideal for a mid-level software engineer specializing in cloud-native backend development to join the exocad Machine Learning team as a Backend Engineer, owning the production services that put ML models in front of users. Working closely with ML researchers, frontend engineers, and product teams across sites, you'll extend and operate the model serving layer behind exocad's dental CAD workflows: inference APIs, deployment and rollout automation, versioning, monitoring, and the performance and cost tuning that keeps them healthy under real workloads. You'll also contribute to the upstream training and labeling infrastructure that feeds them. This role focuses on the engineering that turns research prototypes into reliable, observable, traceable production systems, and on the operational discipline that keeps model behavior predictable release over release. Key Responsibilities Maintain, extend, and operate the production services that serve exocad’s ML models as part of the exocad AI Design product. Own model deployment end to end: containerized builds, versioning, staged rollout, rollback, and reproducible release artifacts. Automate provisioning and deployment with Terraform and AWS-native tooling so environments stay consistent and releases repeatable. Build monitoring into serving systems for latency, throughput, resource utilization, and error rates, and act on what the telemetry shows. Collaborate with engineering, and product teams to deliver compliant and business-aligned cloud and data solutions. Own deployments in both our AWS global and AWS China environments, partnering with our regional experts on data residency requirements. Skills, Knowledge & Expertise Education: Bachelor’s degree in Computer Science, Software Engineering, or a related field, or similar education. Experience: 4+ years in backend engineering, including 2+ years of hands-on experience designing and operating systems on AWS.
