Job description

Job Description

Do you want to own the reliability of cloud load balancing infrastructure that serves thousands of customers at global scale? Are you a senior technical leader who can drive solutions across distributed teams while mentoring the engineers around you? Join our Cloud Networking SRE Team.

The Cloud Networking SRE team (CNETSRE) is part of Akamai's Infrastructure Engineering & Operations (IE&O) organization. We design, deploy, and manage the reliability of Akamai's core cloud networking products — including NodeBalancer, our production L4/L7 load balancer, and NLB, our next-generation high‑throughput L4 load balancing platform. These products are foundational to the Akamai Cloud Compute platform, serving customer workloads across dozens of global regions.

Responsibilities

• Own the SRE lifecycle for NodeBalancer and Network Load Balancer—from design reviews and pre‑rollout readiness assessments through production sign‑off and ongoing reliability management.
• Design and implement SLO/SLI frameworks that reflect true customer experience for L4 and L7 load balancing services, and drive action when error budgets are at risk.
• Build and maintain observability pipelines for NB/NLB infrastructure, including Prometheus metrics and Grafana dashboards that enable rapid incident triage.
• Lead technical incident response for complex NB/NLB failures—BGP/VIP issues, failover failures, data plane degradations, and configuration problems—acting as the technical commander and driving root cause analysis and preventive follow‑through.
• Develop and automate safe deployment workflows for phased NB/NLB releases, including bake period monitoring, feature‑flag management, and GO/NO‑GO validation across global datacenter rollouts.
• Review design documents and product requirement documents and provide actionable SRE input on operational risks, capacity implications, Day‑2 concerns, and product strategy gaps.
• Build automation and tooling using Python or Go that reduces operational toil and improves team‑wide operational capability.
• Mentor SRE II engineers on the NB team, providing hands‑on technical guidance, code/config reviews, and raising the bar for the team's SRE practice.
• Participate in an on‑call rotation for NB/NLB production systems, responding to incidents and driving resolution for customer‑facing load balancing infrastructure.

Qualifications

• Extensive experience in SRE, platform engineering, or infrastructure engineering, working with large‑scale distributed systems.
• Deep expertise with Linux networking fundamentals—routing, BGP, nftables/iptables, ARP, VXLAN—and comfort diagnosing at the packet level using tcpdump, netstat, and similar tools.
• Hands‑on experience with L4/L7 load balancing technologies—proxy‑based or kernel‑level load balancers—covering configuration, health checking, high availability, and failure modes at scale.
• Track record of defining SLO/SLI frameworks, building observability platforms from scratch, and running incident management processes at scale.
• Expertise in Kubernetes and containerization at scale—including workload scheduling, networking (CNI, Services, ingress), resource management, and operating stateful or network‑intensive workloads in a cluster environment.
• Build automation and tooling using Python or Go, with infrastructure‑as‑code experience (SaltStack, Ansible, or Terraform) and strong deployment safety instincts.
• 4+ years in SRE or infrastructure engineering, with at least 2 years at cloud scale.

Benefits

• Your health
• Your finances
• Your family
• Your time at work
• Your time pursuing other endeavors
