  • Oversee daily refill operations across multiple station sites islandwide.
  • Ensure timely and accurate delivery and replenishment of detergent products.
  • Supervise part-time refill crew or contractors as the business scales.

  • Support forecasting and restocking to reduce downtime.
Process Improvement & Reporting
  • Identify bottlenecks and propose improvements in the refill/maintenance workflow.
  • Provide weekly reports on station performance and inventory status.
Ideal Candidate
  • Diploma or Degree in Mechanical Engineering, Electrical Engineering, Mechatronics, Industrial Design, or similar.
  • Familiar with basic plumbing, mechanical fittings, electrical wiring, or sensor calibration.
  • Experience in CAD (e.g., Fusion 360, SolidWorks) and 3D printing is a strong plus.
  • Enjoys hands-on work and solving real-world problems.
  • Physically fit and willing to travel across Singapore frequently.
  • Holds a valid Class 3/3A driving license.
  • Bonus: Prior experience with vending machines, dispensing systems, or sustainability tech.
