Principal Test EngineerDeveloped fully automated tests for Design and System Verification (DVT/SVT) using NI TestStand, LabView, and Ranorex on complex Distributed Antenna systems (DAS), conducting 3GPP physical layer tests such as EVM, ACLR, and Spectral Emissions Mask.• Designed and built automated tests -consistently helped bring 4G and 5G DAS systems to the market on time. • Directed extensive troubleshooting efforts, partnering with remote design engineers and product-line managers to resolve technical issues - quickly creating tests to verify new customer configurations. • Innovative development of 5G automation - one TestStand sequence, using LabView, to test over 40 variations of DAS remotes. • Applied ongoing test revisions to increase productivity and reduce errors. • Compiled information, analyzed test data, and produced detailed reports, including defect reporting on Polarion tools. • Assisted System Verification team members with training on 4G / 5G concepts, Freq domain measurements, Ranorex, TestStand, and LabView. .

Shakopee, Minnesota, United States

Executed design verification (DVT) of wireless products, operating alongside design engineers through all stages of development in a very fast-paced environment.• Created test plans, schedules, hardware, and software for new generations of distributed antenna systems (DAS). LabView/TestStand deployed to check IMD/IP3, S parameters, Spurious Noise, Gain, and Optical parameters. • Developed a Fiber-optic switch instrument, PCB, chassis, and software, complete with computer control. This allowed automation to test a new digital interface card with direction control of optical ports to test equipment. • Collaborated with FPGA designers daily to implement Common Public Radio Interface (CPRI) for the first time at the company. This new capability allowed base-station CPRI commands to configure cellular channels in automated tests. • Developed automated tests using C programming for the entire portfolio of ADC's HDSL product. Teamed with contract manufacturers in Mexico and Taiwan to help with some struggling projects after the cancellation of a large product family and during a rapid reduction of the workforce at ADC.• Team leader for all HDSL product line functional tests. Fixed manufacturing test problems where previously existing tests had memory leaks, etc.• Developed standardized Virginia Panel interface for all HDSL testers. Created hardware for precise measurements of line power current for remote units. • Led troubleshooting for contract manufacturers and developed relationships. Oversaw technicians and set tasks/directions.

Minnetonka, Minnesota, United States

Promoted to manager, with as many as twelve direct reports.• Mentored group during a difficult, fast-paced, and aggressively scheduled project. Brought SONET-based "Cellworx" products online in manufacturing and on schedule. • Trained the team on new technologies, including SONET, switching fabric mechanisms, and DS1/DS3. Managed budgets, hired new people, wrote performance reviews, and promoted within the group.• Acted as test coordinator/liaison to the design department and project managers in Richardson, Texas, traveling to their lab to assist developers in troubleshooting issues with new hardware.• Oversaw production of the Cellworx product, ensuring the purchase of ICT and automated functional tests online on schedule. Leveraged PC-based rack systems using LabWindows CVI, NI Test Executive, VxWorks, and Tornado Tools from Wind River, and Sun workstations.

Minnetonka, Minnesota, United States

Specified and built automated test systems for telecommunications products.• Advanced factory efficiency by creating a test executive in a real-time UNIX environment using C programming. Moved factory away from manual bench tests toward Linux and PC-based automated test systems. • Specified and constructed the first fiber-optic test stations, including developing an automated laser tuning circuit with CPU/Digital control software.• Tested Hybrid-fiber coax systems; developed tests interactively with software engineers, sometimes seven days a week as daily releases of firmware-mandated test updates - enabled us to meet a scheduled delivery contract for several thousand initial units.

Mossville, Illinois, United States

Development Engineer, Software and HardwareDesigned and developed specialized analog and digital instrumentation for the research and test/evaluation divisions of a large construction equipment company. Used UNIX, VxWorks, VRTX, and C programming. Developed software for instruments to measure and record engine speed and acceleration, providing engineers with a means to qualify engines for EPA.• Designed hardware and software for various small instruments and components such as digital peak detectors, engine detonation detectors, and error-of-action for gear sets. One patent was awarded.• Coordinated construction of measurement systems in a multi-million dollar automated engine test facility.• Resolved small conflicts between management and the UAW bargaining unit.
