Senior Mechanical (Mechatronics) Engineer

Hardware-Software Integration

Mechanical & Electrical Systems

Testing, Validation & Reliability

Qualifications

• B.S. or M.S. in Mechatronics, Mechanical Engineering, Electrical Engineering, Robotics, or related field
• 3+ years of hands-on experience in robotic system development, hardware-software integration, or mechatronics
• Strong programming skills in Python and/or C++, with experience in robotic frameworks (ROS / ROS2)
• Deep understanding of robotic system architecture including sensors, actuators, controllers, and embedded interface.
• Experience with motor controllers, firmware interfaces, and real-time communication protocols (CAN Bus, I2C, UART, SPI)
• Proficiency in CAD tools (SolidWorks preferred) and ability to create GD&T-informed engineering drawings
• Strong problem-solving mindset with demonstrated ability to debug across hardware-software boundaries
• Experience with test automation, data analysis, and structured system validation
• Comfortable working hands-on: building, assembling, and iterating on physical prototypes
• Preferred
• Experience with embedded systems, RTOS, or low-level hardware control on edge compute platforms (NVIDIA Jetson or similar)
• Familiarity with FEA or structural analysis tools for mechanism design validation
• Background in industrial, construction, mobile, or field-deployed robotics
• Experience with sensor fusion pipelines (EKF, UKF, or factor graph-based methods)
• Familiarity with functional safety principles, fault tolerance, and degraded operation modes
• Prior experience in an early-stage startup or prototype-to-production environment
• Why Join Us At Spacer Robotics, you won't just be writing code, you'll see your work run on a real robot, on a real construction site, doing a job that matters. You'll join a small, technical team where your contributions have direct impact and your growth into robotics is intentional and supported.
• This is an early opportunity to help build the engineering foundation of a company with a large, defined technical mission. If you're excited about autonomous systems, curious about physical AI, and want to ship something real, we want to hear from you.

Compensation

• The US base salary range for this full-time position is competitive and benchmarked to Bay Area market rates, plus meaningful early-stage equity. The total compensation package may also include additional components depending on the role. This information will be shared if an employment offer is extended.
