Some projects I was involved in are: - Panel alignment module - Motion consent (collision avoidance). - Print head inspection and maintenance module. - Configurable components. - Control software for fan filter unit. - Temperature control. - Image analysis tool to find nozzles (good, mis-directed and missing nozzles). - Handoff modules and factory host interface for several customers. - Mentored software engineers on software architecture, designing modules and tool processes. - Recipe data. ### Senior Software Engineer @ Auxogyn, Inc. Jan 2012 – Jan 2014 | Menlo Park,CA ### Senior Software Engineer @ Ventana Medical Systems, a member of the Roche group Jan 2008 – Jan 2012 Plugin Project • Designed and developed a plugin framework using C#, MEF and Prism. This project allows customized applications and workflows to be implemented quickly as loosely coupled modules communicating with each other with events. Image Processing Algorithms • Implemented techniques for dynamic threshold, color segmentation, blob detection, blob segmentation and reporting. ### Software engineer level III @ Timbre Technologies Inc. Jan 2005 – Jan 2008 Stage Control • Designed and implemented a C# wrapper for the stage control libraries provided by the vendor. Stage Calibration • Designed and implemented center of rotation calibration and camera angle calibration. • Designed and implemented navigation sequence. Stage Characterization • Developed the stage characterization tests both pattern recognition based and encoder based. Recipe running sequence • Developed a simple recipe sequence to study the navigation accuracy. Recipe sequence included wafer alignment sequence. Software reliability project • Reliably achieved 40000 wafer runs for a stress test sequence. Recipe Management System • Developed Recipe Management System to support remote recipe management functionality between various metrology modules within Clean Track process tools. Trouble shooting and support • Worked closely with field support and manufacturing group on several occasions to trouble-shoot critical issues. ### Software Engineer @ Thermawave Inc Jan 2001 – Jan 2005 Partial Fields Project Site measurements for fields that are partially printed • Enabled prospective customers to perform full wafer to wafer measurements for increased statistical sampling in productions as well as test environment by designing and implementing, the ability to measure fields that are partially outside the wafer or outside the exclusion zone. Flexible Measurement technique Measurement on different sites for different fields on a wafer • Designed and implemented the flexible measurement technique which allows the user to do a wide range of measurements on a wafer with a single recipe. Stand Alone Metrology Project Analyzed, designed, developed and tested all phases of stand alone metrology tool • Developed and implemented multi-threaded control software, which is easily customizable to work with two different types of measurement modules and load ports. Led the project from inception to completion. ### Software engg @ Sensys instruments Jan 2001 – Jan 2002 ## Education ### Master of Science (MS) in Computer Science University of Oklahoma ### B.S in Mechanical Engineering Manipal Institute of Technology ## Contact & Social - LinkedIn: https://linkedin.com/in/harshal-varangaonkar-7637065 --- Source: https://flows.cv/harshalvarangaonkar JSON Resume: https://flows.cv/harshalvarangaonkar/resume.json Last updated: 2026-04-01
