Systems Software Engineer

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.

The ML & Robotics Infra team builds the foundational systems that every part of our robot perception, ML, controls and behavior runs on, and the developer infrastructure that lets us build, ship, and update that software quickly and safely on every robot in the fleet.

As a System Software Engineer, you’ll focus on the runtime itself which encompasses the IPC layer, performance, scheduling, observability, logging and replay infrastructure that the rest of the robot software depends on. You’ll work alongside teammates who own the GPU and accelerated compute layer and our build and delivery infrastructure, and you’ll partner cross-functionally with Software, ML, Controls, and Hardware teams to ensure the runtime meets the latency, throughput, and reliability bar required for a real-time robotic system operating in the home.

You’ll own and contribute to core areas of the runtime, including:

• →

• 2+ years of experience developing systems software for high-performance, low-latency, or pseudo-realtime environments (robotics, autonomous vehicles, HFT, or similar)

• Strong proficiency in a systems language such as C++, C, or Rust

• Deep Linux expertise: scheduling, IPC, kernel tuning, memory management, and performance tuning

• Hands-on experience with CPU performance optimization

• Strong systems debugging skills with tools like perf, ftrace, eBPF, and similar tracing infrastructure

• Experience writing systems software for AV, Robotics or other physical systems

• Experience building observability or tracing infrastructure for distributed or multi-process systems

• Experience designing or building high-throughput logging systems and exposure deterministic replay systems

• Experience with build systems and OTA updates

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.
