Summary
👤
Senior🎓
Top SchoolJosh Dewald is a Principal Architect with 17 years crafting resilient, high-performance backend and networked systems, currently leading internet scanning architecture at Recorded Future from Las Vegas. He blends hands-on systems programming (including Rust eBPF tools and Kubernetes operators) with pragmatic API and operational design to stop scans within seconds and scale multi-region deployments. Previously at StackPath he built global load-balancing and traffic-engineering prototypes, reduced egress CPU via eBPF, and created control planes based on XDS—work that spans research-informed experimentation to production rollouts. Known for digging into cluster-wide network root causes and translating observability gaps into durable tooling, he balances deep technical problem solving with mentoring and cross-team influence. An unexpected thread through his career is repeatedly turning research ideas into deployable systems that measurably improve network and CDN behavior.
