Requirements
  • Prior mechanical or manufacturing engineering experience, including internships or project work.
  • Strong skills in computer-aided design and familiarity with rapid prototyping techniques such as 3D printing and machining.
  • Understanding of design for manufacturability and design for assembly principles.
  • A hands-on problem-solving approach with the ability to iterate quickly.
  • Strong collaboration skills and comfort working in fast-paced startup environments.
  • Currently enrolled in a bachelor's or master's degree program studying Mechanical Engineering, Manufacturing Engineering, or an equivalent field.
Responsibilities
  • Support the design and development of mechanical jigs and fixtures for wearable and robotic devices.
  • Contribute to design for manufacturability and design for assembly efforts to scale designs from low-volume prototypes to high-volume production through build analysis reviews.
  • Work with vendors and suppliers on prototyping, tooling, and production readiness.
  • Assist with documentation for manufacturing design reviews.
  • Analyze and optimize manufacturing processes to improve efficiency, reduce waste, and maintain quality standards.
  • Create and maintain detailed documentation, including process maps, workflows, and standard operating procedures.
  • Conduct time and motion studies to identify bottlenecks and implement solutions to enhance productivity.
  • Evaluate and recommend tools, technologies, and equipment to support efficient manufacturing processes.
  • Support the build team in meeting production milestones through a 50/50 split between engineering and production support.
Desired Qualifications
  • Strong skills in computer-aided design, with Onshape or SolidWorks preferred.
  • Experience working on consumer hardware, robotics, or compact devices is a plus.

Sunday Robotics builds Memo, an autonomous home robot that performs chores like washing dishes, laundry, and tidying up. Memo uses a wheeled base, a soft silicone shell, and a telescoping arm to reach from floor to high shelves, and it learns from humans via ACT-1, a foundation model trained on a large real-world dataset collected with the Skill Capture Glove. This in-the-wild data approach lets Memo imitate human actions in real homes and handle unpredictable environments. The company aims to make home robots affordable for many households and plans to deploy through a Founding Family Beta program rather than rely on demos, seeking broad adoption.

Simplify's Take

What believers are saying

  • Target retail price under $10K positions Memo as a consumer appliance, not a luxury item.
  • Founding Family Beta will deploy 50 units in late 2026 to generate closed-loop operational data.
  • 10M+ real-world routine dataset enables ACT-1 to generalize across unpredictable home environments.

What critics are saying

  • $20K/unit build cost vs <$10K price creates fatal unit economics gap risking valuation collapse in 6–12 months.
  • Tesla Optimus and Figure AI target same niche with superior scale, threatening beta adoption in 12–18 months.
  • Wheeled base design is less versatile than bipedal humanoids for multi-level homes, risking obsolescence by 2027.

What makes Sunday Robotics unique

  • Sunday uses a proprietary Skill Capture Glove to collect 10M real household routines from 500+ homes.
  • Memo features a wheeled base and soft silicone shell for passive stability and safety around children.
  • ACT-1 foundation model is trained entirely on zero robot data, bootstrapping intelligence from human demonstrations.
