Scope
Mechanical Engineering Intern supporting multi-disciplinary hardware development within an early-stage startup environment. Contributed across product design, manufacturing process development, and testing to advance multiple hardware products through prototype and validation phases.
Product Design/Development
Contributed to refinement of the core lock mechanism design, supporting prototype iteration and manufacturability improvements.
Designed and 3D printed custom programming fixtures for the Electrical Engineering team to improve PCB flashing efficiency and repeatability.
Performed tolerance stack-up analyses to ensure part compatibility and interchangeability during prototype builds.
Manufacturing
Developed Fusion 360 CAM programs for CNC machining of testing fixture components. Designed and implemented custom fixturing to modify prototype components and machine new hardware for validation purposes.
Oven Temperature Control Unit Project
Designed and built an Arduino-based temperature control unit to regulate an epoxy curing oven. Selected electrical components, completed wiring, programmed control logic, and designed a 3D printed enclosure.
The system improved curing consistency by enabling precise time and temperature control, increasing repeatability and reliability of bonded assemblies.
Summary
This experience provided hands-on exposure to the product development workflow within a hardware startup, strengthening my capabilities in mechanical design, manufacturing execution, cross-functional collaboration, and embedded system integration.
As a Mechanical Engineering Intern at Last Lock I was able to gain experience in the workflow of a hardware start-up and get an in-depth look into the product development and validation process for hardware devices.
