Senior Site Reliability Engineer - Core Cloud Platform

Lambda; United States; Hybrid; USD 160,000 - 220,000; Full time

Job summary

Lambda, The Superintelligence Cloud, seeks a Senior Site Reliability Engineer to boost reliability, scalability, and operational maturity of compute provisioning and infrastructure orchestration across our data centers. You will operate and scale core platform services, define SLIs/SLOs, automate drift detection, and lead incident response.

Proficiency with Kubernetes, Terraform, GitOps tools (Argo CD/Flux), and observability stacks is required.

Qualifications

• 7+ years in site reliability, infra, distributed systems, or production software engineering.
• Deep experience operating Kubernetes in production.
• Knowledge of Kubernetes architecture: scheduling, networking, and upgrades.
• Experience with physical data centers, private/hybrid clouds.
• Proficient with Terraform or similar IaC tools.
• CI/CD or GitOps workflows using Argo CD, Flux, Helm, or Kustomize.
• Observability with OpenTelemetry, Prometheus, Grafana, or Datadog.
• Production-quality tooling in Go or Python.
• Understand distributed systems concepts: consistency, retries, idempotency.
• Experience defining and operating SLIs/SLOs.

Responsibilities

• Operate and scale critical platform services across Lambda’s data centers.
• Improve reliability of compute provisioning, instance lifecycle, and regional orchestration.
• Build monitoring, alerting, and tracing for service health, provisioning latency, and customer-impacting failures.
• Define SLIs, SLOs, error budgets, and operational readiness standards.
• Automate detection and remediation of configuration drift, failed workflows, and orphaned resources.
• Build safe deployment, rollback, and disaster recovery workflows using infrastructure as code and GitOps.
• Design fault-isolation mechanisms that reduce blast radius and prevent cascading failures.
• Lead production incident response, postmortems, and durable corrective actions.
• Partner with Compute, Networking, Storage, Security, and Support teams.
• Participate in on-call and improve its sustainability through automation and better tooling.
• Mentor engineers and raise the reliability bar across the organization.

• Mentor engineers and raise the reliability bar across the organization.

You Have

• YouHave 7+ years of experience in site reliability, infrastructure, distributed systems, or production software engineering.
• Have deep experience operating Kubernetes in production.
• Understand Kubernetes architecture, scheduling, networking, resource management, upgrades, and common failure modes.
• Have experience with physical data centers, private cloud, hybrid cloud, or environments without full reliance on managed services.
• Are proficient with Terraform or similar infrastructure-as-code tools.
• Have built CI/CD or GitOps workflows using tools such as Argo CD, Flux, Helm, or Kustomize.
• Have experience with observability platforms such as OpenTelemetry, Prometheus, Grafana, or Datadog.
• Can build production-quality tooling in Go, Python, or a similar language.
• Understand distributed systems concepts including consistency, retries, idempotency, backpressure, and partial failure.
• Have experience defining and operating against SLIs and SLOs.
