About the Job

Requirements

Have 4–6+ years of experience in backend or infrastructure-focused engineering roles, such as site reliability engineering, platform, DevOps, or full-stack, with at least 2 years owning production systems at scale.
Be able to write or review production-grade code and infrastructure as code, including Terraform, Helm, and GitHub Actions.
Have hands-on production Kubernetes experience, ideally GKE, including autoscaling, ingress or gateway strategies, and network policies.
Have GCP fundamentals, including IAM, VPC design, Workload Identity, Secret Manager, and CloudSQL performance characteristics, and working experience with at least one major cloud: AWS, Azure, or GCP.
Understand cascading failure, timeout boundaries, dependency health, and blast radius.
Regularly contribute to incident mitigation or long-term fixes, beyond closing alerts.
Be able to influence through well-written pull requests, documentation, and thoughtful design reviews.
Have hands-on experience with Cloudflare or a comparable edge, CDN, or WAF platform.
Use Datadog to monitor infrastructure health, capture service-level metrics, and reduce alert fatigue through high-signal thresholds.
Use PagerDuty to own the incident management pipeline, route alerts by severity, and align with business SLAs.
Use GKE and Kubernetes to improve cluster stability and workload isolation, define autoscaling configurations, and tune for efficiency.
Use ArgoCD to keep releases consistent across clusters, monitor sync health, and define safe promotion gates between environments.
Use Helm and GitOps to validate release consistency across clusters, monitor sync status, and ensure rollout safety.
Use Terraform Cloud to support disaster-recovery planning and detect infrastructure changes through state comparisons.
Use CloudSQL to diagnose database and networking issues, monitor latency, enforce access patterns, and validate WAF usage.
Use Cloudflare to manage DNS, WAF, rate limiting, and caching; diagnose edge latency; and validate security rules.
Audit access to secrets, apply short-lived credentials, and define alerts for abnormal usage.
Use Python and Bash to automate toil, build internal tooling, and script diagnostics.

Responsibilities

Design and maintain safe deployment patterns, including blue-green, canary, and progressive delivery, using ArgoCD for GitOps synchronization and Kargo for environment promotion across development, staging, and production.
Instrument logs, metrics, traces, and alerts to improve signal and reduce noise; define service-level indicators and service-level objectives with service owners and drive alerting from them.
Tune GKE workloads, including horizontal and vertical pod autoscaling, cluster autoscaling, node pool strategy, network policies, resource requests and limits, and workload isolation.
Build and maintain reusable Terraform modules for core infrastructure, including VPCs, GKE, CloudSQL, Pub/Sub, IAM, secrets, and Cloudflare, with consistent naming, tagging, and policy enforcement across environments and cloud providers.
Lead or support incident response, diagnose production issues from telemetry, conduct blameless postmortems, and drive long-term fixes to completion.
Detect and eliminate configuration drift; standardize secrets handling, short-lived credentials, and environment parity.
Automate operational toil with Python and shell scripting and harden CI/CD pipelines with clear rollout-readiness standards.

Desired Qualifications

Experience with Kargo or similar progressive promotion tooling, such as Argo Rollouts or Flagger.
Experience developing or integrating Kubernetes operators.
Familiarity with service-level indicators, service-level objectives, and structured alerting.
Experience building or integrating Kubernetes operators and custom resource definitions.
