About the Role

Sesame AI is building a complex and compact wearable hardware AI product requiring custom mechanical parts enclosures fixtures and test rigs. We are looking for a highly organized hands-on Fabrication Technician to support the hardware team with fabrication precision assembly equipment operations and build logistics.

In this role you will commission operate and maintain benchtop fabrication equipment; produce prototype parts to tight tolerances; and keep the lab organized and ready for daily engineering use. You will work under the direction of the Prototyping Lead and alongside mechanical electrical and manufacturing engineers to turn CAD models and drawings into physical hardware - quickly accurately and repeatably.

Responsibilities:

Equipment Commissioning & Maintenance

• Commission set up and bring online new fabrication equipment including 3D printers (FDM SLA/DLP SLS) desktop CNC mills laser cutters and other bench top tools.
