As the first full-time SWE, I build critical hardware test stations and analysis tools that aid the materials scientists and hardware engineers in the R&D process:
• Designed, built, maintained and upgraded 6 separate automated test stations in the electronics lab, each with accompanying data processing/analysis tools. The materials team operates these user-friendly stations, which constitute the characterization pipeline for all new magnetic sensing samples.
• Built a library of reusable, performance-optimized components for hardware control, signal processing, and data visualization in Python using the Numpy/Scipy stack.
• Drafted and enforced company standard software conventions.
• Set up and maintained company CI/CD.
• I am well-versed in the power and RF electronics hardware that make up these test stations. I enjoy the hands-on work of wiring, soldering, maintaining and troubleshooting this hardware.
• Built the first in-house data acquisition program for the integrated sensor prototype, recording magnetic signals via USB.
• Built real-time signal visualizers (combination of oscilloscope and spectrum analyzer) for two generations of the sensor prototype. These work in tandem with acquisition software and are used both by test engineers in the lab and leadership, in demos shown to investors.
• Programmed embedded C to improve upon the sensor microcontroller's firmware, and established SOP for embedded development using TI Code Composer Studio.
