Full Stack Software Engineer; Generalist

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.

To architect the next generation of robotic intelligence, we need versatile engineers to craft the systems that make it possible. As a Full Stack Generalist, you will move across our entire ecosystem, from our global data collection pipeline to our ML training and robot management platforms. We are looking for  0 to 1  builders who thrive on solving complex, high-impact challenges rather than sticking to a narrow roadmap.

• Data Operation Tooling: Scaling our  Data Engine  to manage thousands of global collectors and building high-fidelity tools to audit and distill massive amounts of human motion data.

• Machine Learning Systems: Building the  Laboratory  where our ML team evaluates models, including  human-in-the-loop  observability interfaces and large-scale data processing.

• Robot Fleet Management: Architecting our  Mission Control  to securely identify, monitor, and manage our fleet of robots as they deploy into real-world environments.

• Core Infrastructure: Proactively identifying friction across our stack and building the shared services, APIs, and internal tools that allow the entire team to move 10x faster.

• Full-Stack Proficiency: 5+ years of building and scaling cloud-native applications with mastery of modern frontend (e.g., React, Type Script) and robust backend (e.g., Node.js, Python) stacks.

• Product Intuition: You don't just  take tickets.  You talk to stakeholders, understand the underlying problem, and architect a solution that balances speed with long-term stability.

• Systems Fluency: You have a high  rate of learning  and thrive in high-growth environments where shipping is about balancing fast iteration with high-quality engineering across various languages, frameworks, and infrastructure layers.

• Experience as a founding or early hire; able to define roadmaps where no blueprint exists.

• A curiosity for robotics, ML, or IoT, excited to learn how your software interacts with the physical world.

• Experience building platforms that handle terabytes of data or thousands of concurrent devices/users.

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.
