Summary
👤
Senior🎓
Top SchoolJustin Ely is a Staff Software Engineer and infrastructure-focused tech leader with 12 years of experience building resilient, large-scale systems for both scientific missions and consumer platforms. He began his career calibrating Hubble instruments and researching active galactic nuclei, then augmented that scientific rigor with an MS in Computer Science from Johns Hopkins to pivot into cloud-native platform engineering. Justin has led platform and emerging-technology teams, shipping MLaaS, enterprise mesh, and CDN/DDoS defenses at companies including greymatter, neurothink, and Reddit where he now works on site defense and traffic infrastructure. He combines hands-on expertise in Go, Python, Kubernetes, and distributed networking with a knack for mentoring engineers and translating research-grade processes into production reliability. Based in Minneapolis, he brings a rare blend of astrophysics-trained data intuition and pragmatic platform leadership that helps teams anticipate and mitigate real-world outages. Outside work he’s an avid reader and diver who once wanted to be an astronaut—an early curiosity that still informs his methodical, exploratory approach to engineering.
