Job description

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

As an Embedded Software Engineer, you’ll own platform software for the embedded Linux compute units running our robotics stack. You will collaborate closely with electrical, mechanical, software, and machine-learning teams to integrate our full robotics stack on a new compute.

What You'll Do

• Own the embedded software stack (bootloader, kernel, devicetree, BSP, and drivers) for compute platforms based on SoCs like NVIDIA Jetson, Qualcomm etc
• Develop and maintain Linux kernel drivers and userspace integration for sensors, GMSL cameras, displays, storage, and high-speed interconnects (PCIe, USB, MIPI CSI/DSI, Ethernet, CAN)
• Own build system and BSP layers using Yocto/Buildroot or vendor SDKs like JetPack
• Work with the electrical engineering team to debug and bring up custom carrier boards
• Work closely with the software and machine-learning teams to optimize performance across the entire software stack
• Design and implement OTA end-to-end using RAUC, Mender, SWUpdate, or equivalent

What You'll Bring

• BS or MS in CS, Computer Engineering, EE, related technical field, or equivalent practical experience
• 3+ years of embedded Linux / systems software development, including hands‑on bringup on modern application-class SoCs (NVIDIA Jetson, Qualcomm Snapdragon, or similar)
• Strong proficiency in C and ideally C++ and/or Rust
• Strong experience with Yocto, Buildroot, or an equivalent embedded Linux build system, including custom layers/recipes and production image customization
• Deep understanding of the Linux boot flow, from bootloader to userspace, and low-level peripherals
• Comfortable working alongside electrical engineers: reading schematics, driving scopes, logic analyzers, and JTAG, and debugging at the hardware/software boundary
• Knowledge of power management, secure boot, watchdogs, and other production‑readiness concerns
• Experience developing CI pipelines for embedded Linux images

Nice to Have

• Delivered at least one project from prototype phase into production
• Experience with PREEMPT_RT
• Familiarity with RTOS-based firmware development
• Experience with Python for scripting, data analysis, or test automation

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.
