Staff Software Engineer- Network Systems

Summary

Join ServiceNow as a Software Engineer and build and maintain robust software systems using Python, Go, or Java. Apply your expertise in software design patterns, data structures, algorithms, and testing methodologies to deliver high-quality solutions. Manage load balancing and optimize CI/CD pipelines using various tools and technologies. Automate deployments and manage releases, including rollback strategies. Design and secure containerized applications, and solve complex networking challenges. Troubleshoot and optimize network performance, and integrate programmable infrastructure and network automation into DevOps workflows. This role requires a strong foundation in software development, CI/CD, containerization, networking, and cloud platforms.

Requirements

• 5+ years of software development experience with proficiency in at least two programming languages (Python, Go, Java) including understanding of software design patterns, data structures, algorithms, and testing methodologies
• Expert-level CI/CD and Infrastructure as Code experience using GitLab CI, GitHub Actions, Jenkins, Terraform, Ansible, with hands-on deployment automation, release management, and rollback strategies
• Deep containerization expertise with Docker/Podman including multi-stage builds, security scanning, optimization, and service mesh technologies (Envoy) for microservices communication
• Solid TCP/IP networking foundation including IPv4/IPv6, DNS, HTTP/HTTPS protocols, routing protocols (BGP, OSPF), and network security concepts (firewalls, VPNs, TLS/SSL)
• Practical load balancing and network troubleshooting experience with NGINX, Envoy, F5, cloud load balancers, plus proficiency using Wireshark, curl, dig, and network debugging utilities
• Network automation and programmable infrastructure familiarity with experience integrating network components into modern DevOps workflows
• Cloud platform expertise with hands-on experience in at least one major platform (AWS, Azure, GCP) including compute, storage, networking services, cost management, and multi-environment strategies
• Comprehensive monitoring and observability skills using Prometheus, Grafana, Splunk, ELK stack for metrics collection, alerting, log aggregation, and distributed systems correlation
• Chaos engineering and reliability practices with knowledge of testing principles, change management processes, and feature flag/toggle implementations
• Experience with modern deployment patterns including progressive delivery techniques (canary deployments, blue-green, A/B testing) and cloud-native observability

Responsibilities

• Build and maintain robust software systems using Python, Go or Java
