Hands‑on experience supporting cloud applications (AWS/Azure preferred)
Fluent in writing well‑documented, production‑grade Python code
Excellent grasp of key components of the software development lifecycle, including testing, code quality and security scans, artifact versioning, environment promotion, and deployment models
Strong background in Unix/Linux concepts, configuration, and shell scripting
Experience with container‑based technologies (Docker, Kubernetes, and managed services like Azure AKS and AWS EKS)
Experience deploying changes to large, distributed systems in both cloud and on‑premises
Excellent practical and theoretical knowledge of CI/CD pipelines, sufficient to design, author, and maintain CI/CD codebases
Experience designing and implementing observability components such as alerts, dashboards, monitors, log‑parsing pipelines, and automated remediation flows (experience with DataDog is a plus)
Detail‑oriented approach to writing crystal‑clear technical documentation
What You'll Get In Return
Experience coordinating business‑critical technical initiatives at a massive scale
Hands‑on expertise supporting low‑latency market data applications
Work on cutting‑edge platforms and initiatives that keep your skills at the forefront of the industry
