• Adhere to established coding standards, revision control practices, and software development processes to ensure code quality and traceability.
• Solicit, analyze, and incorporate feedback from customers and end users to continuously improve software functionality, performance, and usability.
• Conduct and actively participate in code reviews and design reviews, providing constructive feedback and ensuring alignment with system requirements.
• Champion new ideas and features, regardless of size, and present them clearly and respectfully to team members and stakeholders.
• Document designs thoroughly with clear code comments, technical reports, and design descriptions to support maintainability and knowledge sharing.
• Track, analyze, and resolve reported software bugs, and perform thorough testing to verify the effectiveness and robustness of implemented fixes.
• Design and develop reusable software and system components and integrate them into both existing and new product designs to improve efficiency and consistency.
• Collaborate closely with electrical hardware engineers in the planning, design, and development of products to ensure software and hardware performance, integration, and compatibility.
• Serve as a technical lead on assigned projects, coordinating with cross-functional teams and customers to meet deliverables and resolve technology or product issues.
• Utilize tools such as MATLAB and Simulink to model, simulate, and validate control algorithms before implementation on embedded platforms.
• Apply real-time operating system concepts to ensure deterministic behavior and reliable execution of embedded control software.
• Use version control tools such as Git to manage source code, branches, and releases across multiple projects.

Essential Skills:

• Master's degree in Electrical Engineering or Mechanical Engineering with an emphasis on control of electric motors and/or DC/DC converters.
• Strong experience in control theory and its application to engineering problems, especially in electric motor and power electronics control.
• Solid understanding of basic physics as it applies to electromechanical and power electronic systems.
• Expert-level proficiency with MATLAB and Simulink for modeling, simulation, and design of control systems.
• Experience with real-time operating systems and their use in embedded control applications.
• Experience developing with Verilog HDL for programmable logic or FPGA-based control implementations.
• Experience with C and C++ for embedded software development on microcontrollers or embedded processors.
• Experience using Git for source code management, version control, and collaborative development.
• At least 3 years of related professional experience in embedded systems, control engineering, or a closely related field.

Additional Skills & Qualifications:

• Experience with Vivado and Vitis design tools for FPGA and embedded system development.
• Experience with MATLAB/System Generator for FPGA-based control design.
• Experience with Mathematica or similar mathematical design and analysis suites.
• Experience working with electric motors, power electronics, and PC board-level hardware.
• Familiarity with firmware development for power electronics and variable frequency drives.
• Ability to work as a technical lead, coordinating efforts across multiple functional groups and with customers.
• Strong documentation skills, including writing clear design reports, specifications, and code comments.
• Ability to effectively communicate complex technical concepts to both technical and non-technical stakeholders.
