2/2005 – 1/2006

Performed HW design validation on MMIC module.  Wrote a data collection program in VB for GPIB data collection replacing an all-manual data collection process reducing data collection time by over 90%.  Built prototype HW for analog RF signal path with MMIC as the front end and ADC output for module level design verification.

 

4/2004 – 2/2005

Performed HW board bring-up/debug testing on all system boards for Gimbal motor drive system.  Gimbal Drive system consisted of a MIL-1553 interface to spacecraft, Servo H-bridge driver, stepper motor driver boards with a redundant set of boards for backup.  Added IEEE-754 floating-point read/write functions to Win DLL used in validation testing of FPGA co-processor. Recommended improvements to parts procurement process saving 2 days with each BOM updated.  Interfaced with outside vendor supplying module assembly and PCB services.

Manufacturing Test Engineer

 

6/2003 – 3/2004

10/2001 – 6/2002,

Developed production test software for BT/WLAN AP.  Test software handled initial firmware loading/configuration/verification, module and full system testing. Led effort in root cause analysis of low yields PCBA’s resulting in changes at both PCBA assembly house and PCB vendor that improved 1^st pass yields over 50%.

Sr. Software/Test Engineer

 

11/1999 – 2/2001

Created an firmware algorithm in C for management of micro-turbine arrays to meet customers preset output power level demand. Algorithm monitored micro-turbine array output power comparing it against a preset threshold and available capacity of micro-turbines running and in standby. When high demands occurred additional micro-turbines were brought on-line or powered up as needed. Hysteresis was built in to prevent toggling micro-turbines on and off-line when actual power demand equaled preset threshold. Wrote tests for micro-turbine control system modules in C.  Control system modules included main motor controller, fuel valve assembly, front panel, and battery controller.  Due to low PCBA yields proposed and started project to perform ICT testing on all PCBA’s.  This project produced increases in 1^st pass testing of over 80%. Project results led Engineering VP to mandate that all new PCB designs included 100% coverage for ICT testing. Managed incoming inspection of HW assemblies increasing 1^st time acceptance to over 70% on all electrical assemblies.

Firmware/Systems Test Engineer

 

8/1994 – 11/1999

Developed firmware tests in C/x86 asm for main product line capable of handling multiple configurations replacing manual tests decreasing test time over 70% per system.  Led test effort for Calif. facility in BABT certification to manufacture products for sale in UK market, approval was granted on 1^st examination. Developed engineering test setup for validation of modem firmware using Dialogic interface cards and Telco CO simulator.  SFW verification testing of AD2182 DSP firmware in assembler for V.32/V.34 and V.90 modems complying with TSB 37A/38. Led pre-homologation testing for modem products prior to external lab certification for foreign countries including adjusting firmware data as needed to complie. Developed POST firmware (C and x86 asm) using Phar Lap extended memory manager for Tier 1 customer.

StorageTek/Amperif Corporation, Bloomfield, CO/Chatsworth, CA 

Sr. Engineer

 

8/1985 – 8/1994

Developed HW diagnostics fin C or IBM-Block Multiplexer (BMX) channel interface connecting a Sequent multi-processor system and IBM mainframes.  Developed new features and sustaining of BMX channel interface card for company’s main Disk-cache system product.  IO card firmware was implemented all in 68K assembler consisting of over 15K lines of code. BMX IO card firmware emulated existing IBM 3380 disk and UNISYS disk cache systems. Additionally developed board level tests in C and 29K asm for a follow-on product to replace original Disk-cache system. Both White and Black box testing were performed on BMX FW using ICE and Host Chanel emulators prior to live testing with mainframe computer. Reduced product transition time from Engineering to Production from 3 months to 3 days for SQL database engine product that included written procedures for system HW testing and SFW loading via magnetic tape.  Led effort starting up Configuration Management system (PVCS) for all engineering FW.
