Design, implement, and tune closed-loop control systems for real-time thermal management during metal additive manufacturing.
Develop PLC logic and CNC synchronized actions for coordinating printing.
Implement PID and advanced control strategies (feedforward, adaptive gain scheduling).
Architect and configure CNC/PLC analog and digital I/O for integrating sensors (pyrometers, thermocouples) and actuators (laser power supplies, shutters, micro-motor pyrometer steering)
Develop and validate control algorithms that adapt to varying print speeds, toolpath geometries, and thermal conditions
Develop advanced waveform generation for electromagnetic coil drivers — including sub-thresholding pulse patterns, variable pulse widths, and complex frequency profiles using the Prio card or equivalent hardware
Collaborate with the print optimization and path planning team to ensure control strategies align with toolpath direction, speed profiles, and feature-type transitions
Serve as the internal bridge to automation integrators and Siemens support for CNC/PLC platform issues
Instrument and characterize system dynamics — measure plant transfer functions, identify thermal time constants, and size controller bandwidth accordingly
Support machine commissioning, integration testing, and design-of-experiments for process development
Maintain rigorous documentation of control architectures, tuning parameters, commissioning procedures, and test results
Bachelor's or Master's degree in Controls Engineering, Electrical Engineering, Mechatronics, or Mechanical Engineering with controls focus (or equivalent demonstrated experience)
2+ years of experience designing and implementing closed-loop control systems in industrial or R&D environments
Strong foundation in classical control theory: PID tuning, stability analysis, frequency response, and system identification
Hands-on PLC programming experience (Siemens, Beckhoff, Allen-Bradley, or similar industrial automation platforms)
Experience with real-time sensor integration (pyrometers, thermocouples, photodiodes, or similar high-speed analog instrumentation)

Experience with non-contact temperature measurement (pyrometry) including spectral filtering and emissivity considerations
Background in thermal process control (welding, heat treatment, laser processing, or additive manufacturing)
Knowledge of advanced control methods: feedforward compensation, Smith predictors for transport delay, gain scheduling, or model-predictive control
Electronics design experience — particularly H-bridge circuits, high-current motor drivers, or power electronics
FPGA or microcontroller programming for custom waveform generation or high-speed signal processing
Familiarity with G-code/CNC part program structure and post-processor development
Experience with machine safety systems (STO, SS1, SLS) and relevant standards (IEC 62443, ISO 13849)
Curious and self-motivated— the kind of engineer who hangs around, asks questions, and tries to figure things out without being told. This is the #1 trait we're looking for
Strong analytical and problem-solving mindset — able to diagnose issues across mechanical, electrical, thermal, and software domains simultaneously
Self-directed and resourceful in an R&D environment where requirements evolve and solutions aren't predefined
Comfortable iterating rapidly: prototype control logic, test on hardware, analyze data, refine
Clear communicator who can explain control system behavior to mechanical engineers, process engineers, and leadership
Collaborative and low-ego — willing to support builds, run experiments, and do hands-on work alongside design work
Comfortable working with external vendors and automation integrators as technical counterpart
Detail-oriented with a systems-level perspective — understands how a control loop interacts with toolpath planning, thermal physics, and part quality
Competitive salary and comprehensive benefits package
Opportunity to work on cutting-edge metal additive manufacturing technology at the frontier of closed-loop process control
Direct impact on product development — your control systems directly determine print quality and material properties
A collaborative, low-ego team environment focused on innovation and execution
Exposure to multidisciplinary challenges spanning controls, laser physics, materials science, and CNC systems
A culture that values curiosity, initiative, and continuous improvement
