- Familiarity with industrial fieldbus and communication protocols (EtherCAT, Modbus TCP, CAN, OPC UA)
- Ability to debug complex system interactions in real-time environments
- Experience working in cross-functional engineering teams
Nice to Have:
- Experience in high-throughput environments (e.g., warehouse automation, robotics fleets, manufacturing lines)
- Exposure to HMI/SCADA systems and visualization tools
- Understanding of safety PLCs and industrial safety standards
- Familiarity with version control and modern development workflows
- Background in embedded systems or Linux-based environments
Day-to-Day:
- Develop and refine PLC logic to support new and existing automation features
- Partner with engineers to integrate and validate system functionality
- Diagnose and resolve issues during testing and live operations
- Participate in system bring-up, testing cycles, and continuous improvement efforts
- Maintain clear technical documentation and contribute to team knowledge sharing
Additional Notes:
- High-impact role supporting critical automation initiatives
- Opportunity to work on cutting-edge robotics and control systems at scale
- Fast-paced environment with strong engineering ownership
