SiGenix was founded by engineers who had honed their collective trades in multi-national medical, transportation and defense corporations. After having grown weary of attending countless meetings that had little to nothing to do with designing and engineering, the original founders decided to form SiGenix where Engineering state of the art systems for would be Job One.


Even though some names have changed throughout our 14 year existence, the drive to engineer hardware and software solutions is not only our job, but our passion.

Greg Yurko
Principal Engineer and Managing Partner

Greg graduated from the University of Pittsburgh in 1983 with a BS in Electrical Engineering. He worked for Westinghouse on radar systems and nuclear power instrumentation hardware and software design for 3 years. Following that, Greg worked for Union Switch and Signal for 9 years developing software for transportation safety systems, specifically cab signalling. He then worked for Respironics for 10 years where he developed embedded software for respiratory therapy systems and eventually became the Director of Engineering for Software Applications and Sleep Diagnostic systems. Greg became a partner in SiGenix in 2005.  

Greg holds 10 US Patents in medical device areas.

Tom Schneider
Principal Engineer and Partner

Tom graduated from the University of Pittsburgh in 1996 with a B.S. in Electrical Engineering. Following graduation, Tom began his career at Adtranz (now Bombardier Transportation) in West Mifflin, where he focused on analog and digital hardware design for propulsion control. In 2004, he accepted a position as hardware design engineer at Tollgrade Communications in Cheswick, PA, where he strengthened his skills in digital hardware design and FPGA/CPLD design using VHDL. Tom joined SiGenix in 2007 as a principal hardware design engineer, becoming a partner in 2009.

Nik Shaffer
Associate Engineer

Nik graduated from Point Park University in 2005 with a BS in Electrical Engineering. While still in school, he worked for Sima Products Corporation on consumer electronics development and weather radios, writing and testing software until the end of the year. Nik then worked at Daedalus Excel for two years as the electrical interface between the end customer and the in-house industrial designers and mechanical engineers. He began working at SiGenix in 2007.

Dave Smail
Principal Engineer and Partner

Dave graduated from the University of Pittsburgh in 1986 with B.S in Electrical Engineering. He moved to Baltimore after graduation and took a job with Westinghouse Defense Systems where he designed digital processing hardware for advanced radar systems. Dave's next career stop was in 1995 with what is now Bombardier Transportation in West Mifflin, PA. He primarily wrote train control and propulsion software for 11 years for Bombardier until he became a partner with SiGenix in the spring of 2006.

Jerry Joseph
Senior Engineer

Jerry graduated from Penn State with a BS in Electrical Engineering in 1981 and from Lehigh University with a MS in Electrical Engineering in 1988. Jerry began his career at Bell Telephone Laboratories focusing on telecommunication system circuit design. With the breakup of the Bell System, Jerry continued working for spin-offs Lucent Technologies and Agere Systems now involved with semiconductor device design as a device designer, device architect, and applications engineer. Jerry’s experience includes analog and digital circuit design with emphasis on data packet switching, data flow control, linear and switching power supplies.

Jim Ashbaugh
Office Manger

Jim graduated from Duquesne University in 1986 with B.A in Political Science and a minor in Social Communication. He received a Certificate in Human Resource Management at the Master's Level in 2005 from La Roche College.
