Mechanical 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.

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.

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
