Top SchoolErin Pennington is a research-focused software engineer with 11 years of experience bridging production-grade web systems and computational biology research. After earning dual BS degrees in Computer Science (Turing Scholars) and Computational Biology from UT Austin, she rose to Senior Software Engineer at Broadleaf Commerce, building high-throughput billing and subscription services that handled millions of users and tens of thousands of requests per minute. She now applies that scalable-engineering mindset to the Marcotte lab, automating high-throughput protein structure prediction workflows on TACC and validating models with ChimeraX. Proficient across Python, R, Java/C#, C/C++, SQL and JavaScript, Erin emphasizes code quality, clear communication, and fast learning—traits that earned her Broadleaf’s 2018 Employee of the Year and leadership responsibilities. Her open-source contributions include backend improvements to the Broadleaf Commerce framework, demonstrating an ability to modernize legacy systems (e.g., moving Hibernate criteria to JPA) while maintaining enterprise compatibility. Based in Austin, she combines production systems experience with hands-on bioinformatics tooling, making her adept at turning complex computational research needs into reliable, scalable pipelines.
