About the position
The Embedded Software Engineer II is responsible for developing moderately complex software system designs for new products as well as design improvements for legacy products. Responsibilities also include exercising sound engineering judgement and presenting analysis summaries which support design decisions. This intermediate level position in the R D department is generally intended for Embedded Software engineers with a Bachelor of Science in Software Engineering or related field and some relevant work experience. The Embedded Software Engineer II will work both independently and in a team environment with Embedded Software Engineers, Design Engineers, Project Managers, and Test Technicians. Collaboration with other departments including manufacturing, QC, and assembly is expected.
Responsibilities
- Develop, implement, and optimize real-time embedded software for motor control applications, including BLDC, stepper, and servo motors.
- Work with low-level firmware development (C/C++ in embedded environments) to interface with microcontrollers, DSPs, and FPGAs.
- Integrate sensor feedback systems (IMUs, encoders, gyros, optical sensors) for closed-loop control and real-time decision-making.
- Collaborate with hardware teams to define motor driver requirements and optimize system performance.
- Develop and maintain communication protocols (UART, SPI, I2C, CAN, Ethernet) for real-time data exchange.
- Conduct debugging, testing, and validation of control algorithms on hardware prototypes.
- Develop verification test plans, check the accuracy of test results, and draw logical conclusions.
- Optimize power management and efficiency in embedded control applications.
- Document designs, test plans, and system performance metrics to ensure maintainability and scalability.
- Drive Continuous Improvement in technical information (i.e., process records, schematics drawings, SOP's, prototype, and fixture drawings) as needed to evaluate and support product design operations.
- Engages in and actively volunteers for Continuous Improvement projects/tasks.
- Participates in and sustains 5S.
- Must follow all required ISO procedures, comply with all work exposure EH&S training requirements, and adhere to SIG SAUER, Inc. security mandates.
- Must be able to travel.
Requirements
- Bachelor's Software Engineering, Computer Science, Electrical Engineering, Computer Engineering or a related field is required.
- 3+ years of experience in embedded software development with a focus on motor control systems.
- Proficiency in C/C++ for real-time embedded programming and Python or similar scripting languages for automation.
- Experience with motor drivers, PWM control, and feedback loops for high-precision applications.
- Familiarity with RTOS (Real-Time Operating Systems) for deterministic performance.
- Hands-on experience with debugging tools and lab tools such as oscilloscopes.
- Ability to develop efficient, low-latency software for embedded platforms.
- Ability to define and resolve problems by collecting and analyzing data, establishing facts, drawing valid conclusions, and executing solutions.
- Demonstrates proficiency in Microsoft Office software including Word, Excel, PowerPoint, and Outlook and Visio or equivalent tools.
Nice-to-haves
- Experience with field-oriented control (FOC) is a plus.
- Strong understanding of control theory, PID tuning, and signal processing techniques.
- Experience in robotics, autonomous systems, or precision tracking applications.
- Knowledge of sensor fusion algorithms for tracking and motion stabilization.
- Background in wireless communication protocols for distributed control systems.
- Design and tune PID controllers for precise motion control and stability.
- Implement digital filtering techniques (e.g., Kalman filters, complementary filters) to improve sensor fusion and tracking accuracy.
