Experience

Senior Test Development Engineer

WHOOP - Boston, MA

July 2022 - Present
  • Architected and maintained a Python-based factory test platform supporting 20 automated stations across four production lines, enabling daily throughput in the thousands and lifetime production in the millions.
  • Led Gen 4 to Gen 5 factory test evolution, improving first-pass yield from ~95% to ~99% through tighter sensor validation, calibration routines, and failure classification.
  • Designed and validated ECG test fixtures and contributed to all major fixture designs spanning board-level test, system functional test, firmware update, and burn-in stations.
  • Implemented production-grade software controls including mandatory unit and simulation testing, test report generation, and software hash validation to prevent unverified code from reaching manufacturing.
  • Owned the factory software release pipeline, integrating GitHub Actions for automated testing, build, and deployment while coordinating internal sign-off and Arena-controlled external releases.

Product Industrialization Test Engineer

Philips - Cambridge, MA

June 2021 - July 2022
  • Re-architected legacy LabVIEW-based test report parsing by rewriting in C#, reducing runtime by over 80%
  • Managed critical test network software by writing and scheduling SQL database sorting using PowerShell scripts to speed up global share-drive data collection
  • Supported emergency CAPA effort using Python and Minitab to analyze over 2,000 production units

Electrical Engineering Intern

Geophysical Survey Systems, Inc. - Nashua, NH

January 2020 - June 2020
  • Developed software to control a 3-axis CNC machine using Python, Lua, and Mach4 to enable ground-penetrating radar (GPR) antennas to synchronize position and measurement data
  • Simulated GPR antennas using XFdtd to varying degrees of real-world accuracy to compare the measured electromagnetic properties of the insulating foam to the nominal values
  • Replicated real-world test cases of GPR applications in XFdtd and used MATLAB to generate data from existing samples to enable faster testing and research during quarantine

Test Engineer Co-Op

Philips - Andover, MA

January 2019 - August 2019
  • Self-taught Mentor Graphics to create the source files and communicated with Sunstone and Screaming Circuits to produce the new PCB interface
  • Wrote and filled out verification/qualification/instruction forms to ensure industrial and legal compliance
  • Learned C# and SCPI to update legacy software to integrate a new arbitrary waveform generator into an existing calibration setup for outgoing ultrasound equipment
