About the role
You will take charge of mechanical design for cleaning tools and actuator systems on autonomous cleaning robots, working from concept through to design freeze and volume manufacturing. The role sits between the arm motion and cleaning logic team, the perception team, the contract manufacturer, and systems integration partners, so it suits an experienced mechanical engineer who enjoys cross-team hardware work in commercial environments.
What you'll do
Lead and support mechanical and electrical design of components and assemblies for integrated cleaning payloads, covering both the robot arm side and the tool side
Specify and integrate the tool changer mechanism, RFID or contact-based tool identification, and electrical and fluid pass-through across the tool change interface
Design brush retention, replacement, and disinfection mechanisms
Design the on-board fluid system including clean water, detergent, and dirty water tanks, plus pumps, valves, hoses, fittings, level sensing, and quick-fill and quick-drain interfaces
Design maintenance-friendly components for field serviceability
Work with the arm motion and cleaning logic team so end effector kinematics, reach, and tool change choreography are built in
Coordinate with the perception team on camera mounting, lighting, and field-of-view at the end effector
Engineer sealing to meet IP65 and IP67 requirements at the end effector, tool changer interface, fluid line connections, tank interfaces, and manipulation mechanism actuators
Define brush selection criteria and run head-to-head efficacy testing against the project's cleaning quality benchmark, covering geometry-critical zones
Engineer the brush-to-toolchanger interface for fast, repeatable docking and undocking through the disinfection cycle and during field service
Run brush life-cycle and chemical-compatibility testing, and define replacement intervals, consumables BOM, and a supply strategy that scales
Lead FMEA across end effector, brushes, fluidics, and manipulation mechanisms, and define service intervals and design for field-replaceable wear items
Design the mechanism by which the robot manipulates cleaning fixtures such as doors during the cleaning cycle with safe behaviours
Design for graceful failure in human-shared environments so manipulation motions do not pinch, trap, or surprise people, and the mechanism fails to a safe state on power loss or detected obstruction
Drive Design-for-Manufacturing with the contract manufacturing partner
Conduct field testing to validate cleaning performance
Good to know
Selected candidates will be invited to complete a design exercise and attend an on-site interview at the office
Applicants should upload a CV and include a brief note in the Cover Letter field describing a mechanical design problem they owned end-to-end, including challenges, key decisions, and the final outcome
A portfolio of relevant mechanism, end-effector, or tooling projects is welcome if a
Requirements
Bachelor's or Master's degree in Mechanical Engineering, Mechatronics, Robotics, or a related field
5+ years of professional mechanical design experience, with at least 2 years on robotic, automation, or precision motion systems that shipped to a customer or production environment
Demonstrated experience designing end effectors, robotic tooling, grippers, or quick-change tooling, with a specific shipped or piloted design to discuss
Strong CAD proficiency in SolidWorks, Fusion 360, or Siemens NX, including assembly management and PDM workflows
Hands-on fluidics experience with pumps, valves, flow control, sealing, leak testing, and IP ratings
DfM experience working directly with contract manufacturers, including tolerance analysis, BOM ownership, and supplier-side problem solving
