Responsibilities
- Lead the design and implementation of real-time control systems for automated medical device manufacturing equipment.
- Define software architectures that integrate microcontrollers, PLCs, motion controllers, sensors, and human-machine interfaces.
- Design and optimize motion control solutions for high-precision automation, including servo and stepper motor control.
- Provide technical guidance on hardware selection, control strategies, safety interlocks, and network communication protocols.
- Serve as the primary software technical authority during design reviews, risk assessments, and design verification activities.
- Develop and maintain embedded firmware in assembly/C/C++ for microcontrollers (examples include 68000, ARM Cortex, Microchip, Maxim Integrated).
- Develop and maintain Windows Visual Studio HMI applications in C/C++/C#/WPF (BW-TEC HMI).
- Create structured PLC software (Ladder Logic, Function Block Diagram, Structured Text) across Allen-Bradley, Beckhoff, and Omron platforms.
- Implement deterministic communication between embedded controllers, PLCs, and supervisory systems (EtherNet/IP, Modbus, CAN, RS-485, SPI, I2C, etc.).
- Build user interfaces and operator controls through HMI systems for production environments.
- Ensure software modules are robust, maintainable, and traceable to design inputs and risk mitigations.
- Collaborate with mechanical, electrical, and process engineers to deliver integrated control solutions for precision motion, fluidics, robotics, and safety systems.
- Participate in design verification and validation testing, including protocol creation, execution, and documentation per QMS requirements.
- Support factory acceptance testing, site acceptance testing, and field support of deployed systems.
- Conduct root cause analysis and implementation of corrective actions for software-related field or production issues.
- Contribute to company-wide software standards for automation platforms and embedded systems.
Requirements
- Solid working knowledge of microcontrollers (ARM Cortex, Microchip, STM32, etc.), PLCs (Beckhoff, Omron, Allen-Bradley, etc.), FPGAs, sensors, and communication interfaces (I2C, SPI, UART, CAN, Ethernet, Modbus, Profinet).
- Strong experience with Microsoft Visual Studio development using C, C++, C#, and C# WPF.
- Expertise in IEC 61131-3 programming languages and embedded assembly/C/C++.
- Strong analytical and debugging skills using oscilloscopes, logic analyzers, and network tools.
- Excellent documentation, communication, and leadership capabilities.
- Ability to balance innovation with compliance and risk management.
- Proven leadership and mentoring abilities with collaborative, cross-functional work style.
- Master’s or bachelor’s degree in computer science, computer engineering, or related field.
- 8+ years developing software for microcontroller and PLC-based platforms with a Master’s degree or 10+ years with a degree, including at least 3 years in a technical leadership or principal engineer capacity.
- Proven track record of bringing products from concept through production.
