Key Responsibilities

#

Prototyping & Fabrication (Build and Hack)

Design small mechanical improvements using

CAD software

(e.g., Fusion 360), and fabricate them using

3D printers

or hand tools. Tweak station components or mounts for improved usability, durability, or performance. Help test new station modules or enclosures before islandwide rollout.

#

Embedded Systems & Rapid Testing (For the Tinkerers)

Assist in sensor integration (e.g., load cells, flow sensors) or microcontroller tinkering (e.g., ESP32, Arduino). Support early-stage development of hardware logic, triggers, or sensor feedback loops. Help log field data and test firmware/hardware behavior in real-world conditions.

#

Field Operations & Refill Logistics

Drive our refill van and execute detergent refills across a network of smart stations islandwide. Monitor and maintain optimal stock levels across sites to prevent downtime. Maintain basic cleanliness, calibration, and functional checks of each station. Supervise part-time crew or field contractors as needed.
