Job Description:

PagerDuty is seeking a Senior Systems Engineer who will design, implement, and maintain critical network infrastructure. The role requires the candidate to ensure availability, performance, and security of internal systems, cloud environments, and global office networks. This includes responsibilities such as architecture design, automation development, security controls, and incident response. The candidate will also contribute to the evolution of PagerDuty’s network infrastructure using a security‑first mindset and automation tools.

Job Responsibility:

Design and implement scalable solutions across our global infrastructure—including office networks, endpoints, and cloud environments (AWS, GCP, Azure)—with a focus on reliability, security, and user experience
Own day-to-day operations of core infrastructure services (network, endpoints, identity, and access), ensuring availability, performance, and scalability across sites and cloud platforms
Provide Tier 2/3 incident response and problem-solving for complex infrastructure issues (network, systems, and connectivity), driving swift resolution and thorough root cause analysis to minimize impact
Implement and maintain security controls and policies across the network and systems, including firewall rules, segmentation, zero-trust principles, and IAM (Entra, Azure AD, Okta) to ensure secure, consistent access
Use monitoring, logging, and packet analysis tools to detect, diagnose, and remediate performance and reliability issues
proactively recommend and implement improvements across infrastructure components
Develop and maintain automation (e.g., Python, PowerShell, Bash, Ansible, Terraform, Workato, Zapier) to standardize configurations and streamline workflows for endpoints, network, identity, and access management
Partner with infrastructure and security teams to ensure network, endpoint, identity, and SaaS integrations follow best practices in Azure, AWS, and/or GCP, supporting secure and scalable hybrid environments
Provide advanced support to employees globally using ITSM tools such as Jira, and contribute to internal knowledge sharing and, where needed, user-facing training materials
Maintain clear, comprehensive documentation for infrastructure configurations, standards, runbooks, and procedures to support repeatable and reliable operations
Create, manage, and respond to alerts (PagerDuty) for infrastructure services and participate in the on-call rotation to ensure 24/7 coverage

Requirements:

8+ years of experience in enterprise network engineering and operations
5+ years in a systems administration/engineering or IT support environment
Professional network certification (e.g., CCNP, JNCIP, or equivalent) or equivalent hands-on experience
Extensive experience with TCP/IP networking and routing protocols (e.g., BGP, OSPF), as well as experience with VPNs, wireless, and modern networking concepts in large-scale distributed environments
Demonstrated proficiency with network automation using Python, Ansible, Terraform, or similar tools
Experience working with IAM tools (Entra, Azure AD, Okta) and processes (account lifecycle, permissions, privileged account management)
Experience supporting a mixed endpoint environment including macOS and Windows

Nice to have:

Strong background in network security, including DDoS mitigation, IDS/IPS, and zero-trust architecture
Experience designing and optimizing global WAN and hybrid cloud connectivity
Familiarity with the full VDI lifecycle, from design and implementation to optimization and ongoing maintenance
Track record of mentoring engineers, leading cross-functional technical initiatives, and influencing architecture and strategy in a global team environment
Ability to independently lead troubleshooting efforts for complex, cross-domain (network + systems) issues
Strong communication and interpersonal skills, with the ability to clearly explain complex technical concepts to both technical and non-technical stakeholders
Ability to work independently and collaboratively as part of a distributed, global team, and to influence leadership in setting group objectives and technical direction
