Senior🎓
Top SchoolCharlie Mihran is a software engineer with 12 years of experience designing and operating large-scale distributed systems, currently delivering Risk and PnL data at Citadel. He built core infrastructure at AWS Athena—overhauling a legacy Java microservice to handle 150M+ daily requests across 30+ regions, cutting transient failures by 70% and latency by 45%. Comfortable across Java and Python, he designs API layers, async pipelines, container orchestration, and IaC while embedding CI/CD, metrics, and alarm-driven operations into every system. As a founding engineer on Athena’s Admission Control team, he scaled the team, mentored 10+ hires, and automated pipelines that save hundreds of developer-days annually. Based in New York, he pairs deep backend systems craft with pragmatic product collaboration and a knack for finding optimizations that materially improve reliability and operational overhead.
