Principal Software Engineer

Cisco's Splunk Enterprise Security team builds software and cloud product capabilities that help customers gain actionable security insights. The team connects security engineering, security operations, and cloud product architecture to support enterprise-scale deployments. It works closely with product managers, security architects, security operations practitioners, engineering teams, and customer support. The team is a place to lead complex initiatives, mentor engineers, and shape secure, resilient products that improve customer outcomes.

As a Principal Software Engineer, you will lead the architecture, development, and delivery of secure cloud product capabilities and services that support enterprise-scale security operations. You will translate security and operational requirements into scalable architectures, technical designs, APIs, data flows, integrations, and implementation plans. You will design, implement, test, deploy, operate, and continuously improve production software while applying secure coding, threat modeling, privacy by design, automated testing, CI/CD, and production-readiness practices. You will partner across security, product, engineering, and customer-facing teams to resolve complex challenges involving security controls, data ingestion, distributed systems, reliability, and performance. You will mentor engineers and drive measurable improvements in operational outcomes, product adoption, and customer value.
