Role Description

Lumen's Network as a Service (NaaS) platform delivers on-demand networking at scale. As Lead SRE, you'll own the reliability of that platform — partnering with operations teams and development counterparts to drive technical direction and resolve systemic issues across a broad range of network topologies and applications.

• Accountable for platform observability, incident management, and automation.
• Coordinate across architecture, engineering, and systems development organizations to measurably improve reliability.
• Use AI and agentic tooling to build utilities that accelerate deployment automation, platform administration, and incident investigation.
• Draw on networking fundamentals, cloud platforms, software development and troubleshooting methodology.
• Drive meaningful impact for the customers who rely on the platform.

Qualifications

• Bachelor’s degree or equivalent in engineering, computer science, or related field.
• 8+ years in software development, systems engineering, and/or networking.
• 5+ years of related experience required.
• Hands-on experience with at least one major cloud platform (AWS, Azure, or GCP), including compute, networking, and identity services.
• Strong automation and infrastructure-as-code skills: Terraform, Ansible, and Python.
• Experience running containerized workloads on Kubernetes.
• Working knowledge of modern observability and monitoring tooling (e.g., Datadog, CloudWatch, Grafana, Prometheus).
• Demonstrated experience with incident management and blameless postmortems.
• Comfort using AI-assisted development and agentic tools as part of daily engineering practice.
• Understanding of network technologies including Internet, Ethernet, IPVPN, Edge Compute, and Optical transport.
• Strong listening and communication skills; able to operate with autonomy while knowing when to escalate.

Requirements

• Participate in an on-call rotation and lead incident response for service outages and unplanned downtime.
• Drive blameless postmortems and root cause analysis; own follow-up actions through to completion.
• Prevent recurrence through process improvements, tooling, and knowledge sharing across teams.
• Automate deployment pipelines (CI/CD) and cloud infrastructure provisioning, scaling, and configuration using infrastructure as code.
• Develop tools and utilities that reduce toil and empower operations and development teams to manage services independently.
• Apply AI-assisted and agentic workflows to development, support, and investigation work.
• Collaborate with cross-functional development teams to support, enhance, and scale NaaS applications.
• Provide guidance and mentorship to junior engineers.
• Maintain clear documentation for processes and architecture.
