Summary
👤
Senior🎓
Top SchoolConnor Skennerton is a Principal Software Engineer with 15 years of experience applying computational rigor to biology-driven problems and production-grade engineering at scale. He holds a PhD in Microbial Ecology and moved from academic bioinformatics—where he built a multi-omics SQL database at Caltech and contributed to Biopython/BioSQL—to industry roles designing ETL/ELT pipelines, data warehouses, and full-stack internal tools on AWS. At companies including Second Genome and Pendulum Therapeutics he combined lab-facing product design with robust devops, automation, and test-driven practices, and now leads platform and systems work at Roblox. Fluent in Python and experienced across many languages and stacks, he is especially focused on reproducible analysis, efficient data processing, and translating wet-lab requirements into production systems. An interesting through-line: he has repeatedly bridged domains, shipping both research-grade bioinformatics infrastructure and user-facing web applications (including an open-source tax-filing app), demonstrating rare versatility between science and software.
