Robotics Engineer - Software - Mid-level

About the CompanySpacer Robotics is building autonomous, non-humanoid robotic systems to constructinfrastructure in extreme environments—from lunar bases to next-gen terrestrial job sites. Ourvision is to disrupt the $16 trillion global construction industry by pioneering a new Deep Techphilosophy that blends robotics, AI, and systems engineering at the frontier.About the RoleThe role on-site in San Francisco, no remote candidates will be considered for this role. We build next generation of robots and interaction with hardware is a must. We're seeking a Mid-level Robotics Software Engineer to join the core team building Spacer'sproduction-level robot. This is a highly hands-on, multidisciplinary role spanning the fullautonomy stack—from raw sensor data through perception, localization, planning, and control.You'll be a technical self-starter who thrives with broad ownership, can make sound architecturaldecisions independently, and is energized by building real systems on physical hardware inunstructured environments. As an early hire, you'll shape our engineering culture and leave alasting mark on how our robots think, see, and move.ResponsibilitiesAs a Robotics Engineer, you will be expected to be versatile, making key contributions toa range of components in the Spacer software stack, including:Robotics Software Stack: Develop and maintain our ROS-based control systems for real-time robotic motion and coordination for our rebar-tying robot GRIDEmbedded Systems: Strong skills in C++ for embedded platforms, optimizing for reliability and low-latencySensor Integration: Interface with cameras, lidar, IMUs, and encoders to build robust perception and feedback loopsHardware-Software Integration: Work closely with hardware engineers to debug, calibrate, and optimize the full system, including the construction tasks specific mechanismsMotion Planning & Control: Implement kinematics, trajectory planning, and control algorithms for smooth, natural movementProduction-Ready Systems: Build the monitoring, diagnostics, and update infrastructure needed for manufacturing a high-volume product that is aimed at navigating the construction environment & outdoors temperatures and weather conditions.Required:3+ years of professional software engineering experienceStrong C++ skills—you're comfortable with performance optimization, memorymanagement, and debugging complex systemsPython proficiency for scripting, testing, and rapid prototypingExperience with sensors, cameras, motors, or embedded systems in a professional contextExcellent debugging skills—you know how to track down issues across hardware, firmware, and softwareHigh energy and enthusiasm for building physical productsBased in or willing to relocate to the San Francisco Bay Area. Our team works in-person which is essential for hardware developmentGenuine excitement about early stage startup culturePreferred:ROS/ROS2 experienceShipped a robotics product or worked on production robotic systems or similar (cars, automation of equipment, other robotics applications, etc)Embedded development experienceComputer vision, sensor fusion, or perception experienceBackground in controls, kinematics, or motion planningExperience working in high pace, early stage startupsCompensationThe US base salary range for this full-time position is $120,000–$180,000 annually, dependingon job-related knowledge, skills, and experience. As one of our early engineering hires, yourequity stake will be meaningful and reflect the impact you'll have building our technology from the ground up.
