In this role, you will design, develop, deploy, and scale control systems software on the CODESYS platform that runs the mechanical infrastructure of AWS data centers - the systems that keep our facilities cool, efficient, and reliable. You will work at the intersection of software development and physical infrastructure, developing the control logic for the newest generation of in-house mechanical controllers. As the controller components you develop go into their first-of-kind builds, you will occasionally travel on-site (approximately 15%) to provide real-time break/fix support and validate your work in the field. Key job responsibilities • Design, develop, and maintain mechanical control systems software on the CODESYS (IEC 61131-3) PLC platform for AWS data center infrastructure. • Develop and refine control logic, function blocks, and Sequences of Operations (SOO) to meet performance and reliability requirements across varied site types and equipment vendors. • Perform triage, root-cause analysis, and remediation of control system issues. • Support first-of-kind builds - the first field deployment of a newly developed controller component - including occasional on-site travel to provide real-time break/fix support. • Partner with our electrical controls counterparts, Controls Design Engineering, Field Engineering, and other Data Center Engineering teams to develop the next generation of controllers. • Document control system designs, configurations, and sequences of operation. • Participate in design reviews and contribute to continuous improvement of controls development standards and tooling. • Participate in an on-call rotation to provide escalation support for critical control system issues.
