# Joshua Wei > Principle Software Development Engineer at Roche Sequencing Location: Los Gatos, California, United States Profile: https://flows.cv/joshuawei ## Work Experience ### Software Development Engineer @ Roche Sequencing USA Jan 2022 – Present | Santa Clara, California, United States Provide software and protocol development for Roche-owned Sequencing Solution and further research efforts Support transition to product facing code Maintain sequencing fleet by debugging hardware and software ### System Engineer @ Roche Sequencing Jan 2017 – Jan 2022 | Santa Clara, California Support development of Python frontend code for the DNA sequencing platform Optimization and maintenance of the Tecan robotic movements and fluidic path of the sequencer Analysis of large scale sequencing data using JMP and Python ### Scientist I @ Genia Technologies Jan 2016 – Jan 2017 | Santa Clara, CA Ran daily sequencing experiments targeted at protocol optimization and baseline maintenance Analyzed data using JMP and Python ### Graduate Researcher @ Institute of Engineering in Medicine - Jacobs School of Engineering Jan 2014 – Jan 2016 | University of California: San Diego Explored the miRNA response to biophysical changes to cell morphology in the induction of myogenic differentiation in mesenchymal stem cells. Fabricated nanoscale features for cell seeding using soft lithography techniques. Validated the production of smooth muscle markers by qPCR and western blotting. ### Research Assistant @ Institute of Engineering in Medicine - Jacobs School of Engineering Jan 2012 – Jan 2014 | University of California: San Diego Isolated the SSH-2 protein in order to test specificity to high binding affinity compounds found through in silico screening using the DOCK6 modeling program. Continued screening work and analysis of data generated through PRIME internship. ### Summer Intern @ NXP Semiconductors Jan 2013 – Jan 2013 | San Jose, CA Tested Proximity Integrated Circuit Cards with EMV radio frequency identification readers to check and increase standardization across NXP lab sites. Designed and built reader platform using AutoCAD to construct a robotic platform for large scale testing of RFID reading volumes. ### Research Intern @ UCSD PRIME Program, Pacific RIM Experiences for Undergraduates Jan 2012 – Jan 2012 | Cybermedia Center, University of Osaka Researched abroad at the Cybermedia Center, University of Osaka, Japan to find high scoring compounds of potential inhibitors of SSH-2. Ranked banks of ligands for binding specificity to members of the dual specificity phosphatase protein family using the virtual docking simulator, DOCK6. Interacted in a foreign environment to practice building relationships across cultures and learning to adapt in new situations. ### Research Assistant @ Department of Bioengineering - Jacobs School of Engineering Jan 2011 – Jan 2012 | University of California: San Diego Researched the phase shift between the circadian clocks of E. coli cells depending on a varying distance based on a linear function. Fabricated the microfluidic chips by soft lithography to recreate easily controllable and observable conditions for the cellular microenvironments. Drafted the microfluidic chip features in AutoCAD. ### Internship @ ViVOtech Jan 2011 – Jan 2011 | Santa Clara, CA Researched barcode generation and created a Java wrapper for an API that generated various barcode types. Reformatted the UI of the VIVOtech website using HTML and JBoss. Created charts of the company’s database using Oracle SQL Developmental Data Modeler. ## Education ### Masters of Science in Bioengineering and Biomedical Engineering UC San Diego ### Bachelor of Applied Science (BASc) in Bioengineering and Biomedical Engineering UC San Diego ### Bioengineering UC San Diego ## Contact & Social - LinkedIn: https://linkedin.com/in/joshua-wei-07882721 --- Source: https://flows.cv/joshuawei JSON Resume: https://flows.cv/joshuawei/resume.json Last updated: 2026-04-10
