We are seeking a hands-on Senior Real-Time Motion Control Software Engineer to take ownership of our motion control and real-time slave system. This is a deeply technical roll ideal for an engineer who enjoys solving real-world control problems at both the software and machine level.

Role focus:

~60% real-time motion/slave system

~40% Windows-side C/C++ and Win32 integration and PLC logic

You will work directly at CNC machines to diagnose, tune, and validate motion performance.

Key Responsibilities

Real-Time Motion Control

• Own and maintain real-time motion control software written in C
• Support and ultimately own the RTX64 real-time implementation
• Manage deterministic scheduling, thread priorities, and core affinity
• Diagnose and resolve latency-sensitive and -condition issues
• Tune PID loops and feed-forward control
• Analyze step response and diagnose servo instability on physical machines
• Validate motion behavior hands-on at CNC machines

PLC & Machine Logic

• Maintain and extend our proprietary PLC system (written in C/C++)
• Develop new PLC logic to support expanded I/O and new machine features
• Debug field I/O and machine sequencing issues

Platform Modernization

• Support migration from Windows CE to Windows 11 IoT + RTX64
• Refactor and improve motion-related code where appropriate
• Ensure long-term stability and maintainability of the motion platform

Required Qualifications

• BS or MS in Electrical Engineering, Computer Science, Mechanical Engineering, or related field
• 10+ years of professional software development experience
• Strong C programming experience in real-time systems
• Strong C++ experience in Windows/ environments
• Experience working in deterministic or near real-time systems
• Solid understanding of:
• Thread prioritization and concurrency
• Core affinity and real-time scheduling
• Interrupt-level timing constraints
• Strong control theory background, including:
• PID control
• Closed-loop feedback systems
• Step response analysis
• Feed-forward techniques
• Ability to diagnose servo instability on real hardware
• Comfortable working hands-on with CNC machines

Experience

• Experience with RTX64, IntervalZero, or similar RTOS platforms
• Background in CNC, robotics, aerospace, disk drives, semiconductor equipment, or industrial automation
• Familiarity with EtherCAT/TCP/UDP networking and/or industrial communications systems
• Experience migrating legacy real-time platforms
• Comfortable working with Visual Studio
