Systems Engineer
March 2026 - Present / San Jose, CA
- Built Python signal-processing and LabVIEW pipelines to process raw SEM data and characterize settling dynamics for SEM stage control hardware, integrating TCP/UDP data acquisition to tune inertia compensation and reduce time to tolerance from 300 ns to 20 ns.
- Developed automated board test and calibration framework across six board families, covering clock phase, frequency, gain, and AC/DC measurements through a Python test engine, PyQt6 GUI, and SCPI/GPIB/NI-DAQmx drivers.
- Designed a Flask/SQLite system of record for firmware and hardware revisions across 90+ boards, with admin CRUD and SQL/CSV export tools that exposed configuration conflicts and informed fleet deployment decisions.
- Recovered and validated 5 to 6 unresponsive boards per week through cleanroom handling, AMD Vivado FPGA debugging, register probing, and targeted firmware updates before reinstallation.
