Mechanical Engineer

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

We are looking for a Mechanical Engineer to help design, build, and scale the mechanical systems that power our robots and data collection devices. You will play a key role in turning prototypes into reliable, manufacturable products, working hands-on with early designs and suppliers to ensure quality and scalability.

This role is ideal for an engineer excited about working across the full product lifecycle - from whiteboard sketches and 3D CAD to testing, validation, and manufacturing handoff.

What You'll Do

• Support the design and development of mechanical components and assemblies for wearable and robotic devices
• Rapidly prototype, test, and iterate on designs to improve performance and reliability
• Contribute to DFM/DFA efforts to ensure designs can scale from low-volume prototypes to high-volume production
• Work with vendors and suppliers on prototyping, tooling, and production readiness
• Perform basic analyses (tolerance, structural, thermal) to validate design decisions
• Assist in documentation for design reviews, testing, and production release
• Collaborate with cross-functional teams (electrical, software, industrial design) to integrate mechanical systems

What You'll Bring

• 2+ years of mechanical engineering experience (this post includes all levels)
• Strong skills in CAD (OnShape or SolidWorks preferred) and a familiarity with rapid prototyping techniques (3D printing, machining, etc.)
• Understanding of DFM/DFA principles and interest in scaling prototypes to production
• Experience working on consumer hardware, robotics, or compact devices is a plus
• Hands-on problem-solving approach with ability to iterate quickly
• Strong collaboration skills and comfort working in fast-paced startup environments
• Bachelor's degree in Mechanical Engineering or related field (Master's a plus, but not required)

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.
