Robotics Systems Engineer

Department: Robotics

Location: Redwood City, CA

Employment Type: FullTime

Join Us in Building the Future of Home Robotics

At Sunday, we're developing personal robots to reclaim the hours lost to repetitive tasks. We're focused on an ambitious goal to make generalized robots broadly accessible, enabling households to take back quality time.

We have spent the last 18 months building a talented team, securing capital, and validating our technology. We are now seeking passionate individuals to join us in the next phase of our growth. If you are ready to apply your skills to the forefront of robotics innovation, we’d love to hear from you.

What to Expect

In building robots for the home, we are tackling a true grand challenge in robotics: dexterous and safe mobile manipulation in unstructured environments. To make this possible, we are building across the entire robotics stack. We’re training state-of-the-art AI models that leverage our large-scale, high-quality, real-world data collection system. At the same time, we’re building a new kind of consumer hardware product, which will be deployed into homes and delivering real value for real customers. As an early member of a small, cross-functional team, you’ll play a key role in pushing both our technology and product forward: advancing the frontier of embodied AI, and soon giving countless hours back to our customers so they can spend more time on the things they value most.

As a Robotics System Integration Engineer, you’ll play a central role in delivering reliable, safe, and capable home robots to consumers at scale. You’ll work closely with mechanical, electrical, and software engineers to diagnose and resolve issues with our existing robots. You’ll use these findings to refine our manufacturing and QA processes, and inform the system architecture and requirements for future design cycles. This role offers significant scope and ownership, and the chance to help shape cutting-edge technology into a cohesive, trustworthy product.

What You’ll Do

• Integrate and test robotic systems, including both actuation and perception hardware

• Triage and debug cross-disciplinary issues spanning mechanical, electrical, firmware, and software systems

• Bring up, test, and evaluate key components, such as sensors and actuators

• Maintain motor and sensor drivers, and related software tools, in Python / C++

• Develop clear processes for robot assembly, bringup, QA testing, and troubleshooting

• Help define component and subsystem performance requirements, and develop test plans to ensure reliable robot operation across a diverse range of tasks and environments

• Support design of robot HW and SW systems, collaborating across teams to optimize the architecture of next-gen robot products for safety, performance, reliability, cost, and manufacturability

What You’ll Bring

• 3+ years of experience working with complex robotic or electromechanical systems

• Proficiency in Python or C++

• Strong system-level understanding of robotics hardware, firmware, and software layers

• Deep familiarity with standard diagnostic tools (oscilloscope, multimeter, logic analyzers)

• Experience developing test plans and procedures for electromechanical systems

Nice to haves

• Deep experience in protocols including CAN, Ethernet, USB, MIPI, GMSL

• Experience with quasi-direct-drive actuators

• Experience calibrating computer vision systems

At Sunday Robotics, we’re building technology shaped by real people — curious, creative, and diverse. We’re proud to be an equal opportunity employer and consider all qualified applicants regardless of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.

Even if you don’t meet every single requirement, we encourage you to apply. Studies show that women and underrepresented groups often hold back unless they meet 100% of the criteria — we don’t want that to be the reason we miss out on great talent.
