We encourage applications from a diverse range of backgrounds and experiences.

• *Key Responsibilities:**

• Design and maintain safe deployment patterns (blue\-green, canary, progressive delivery) using ArgoCD for GitOps sync and Kargo for environment promotion across dev, staging and production.
• Instrument logs, metrics, traces and alerts to improve signal and reduce noise; define SLIs and SLOs with service owners and drive alerting from them.
• Tune and troubleshoot GKE workloads: autoscaling (HPA/VPA, cluster autoscaler), node pool strategy, network policies, resource requests/limits and workload isolation.
• Build and maintain reusable Terraform modules for core infrastructure (VPCs, GKE, CloudSQL, Pub/Sub, IAM, secrets, Cloudflare), with consistent naming, tagging and policy enforcement across environments and cloud providers.
• Lead or support incident response, diagnose production issues from telemetry, run 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.

• *Skill Requirements:**

We understand that candidates may not have every single skill listed below. We encourage you to apply if you possess a strong foundation in product ownership and a willingness to learn and grow.

• Have 4–6\+ years of experience in backend or infra\-focused engineering roles (e.g., SRE, platform, DevOps, or fullstack), with at least 2 years owning production systems at scale.
• Can confidently write or review production\-grade code and infra\-as\-code (Terraform, Helm, GitHub Actions, etc.).
• Deep hands\-on Kubernetes experience in production, ideally GKE, including autoscaling, ingress/gateway strategies and network policies.
• Solid GCP fundamentals (IAM, VPC design, Workload Identity, Secret Manager, CloudSQL performance characteristics) and working experience with at least one major cloud (AWS or Azure or GCP).
• Think in systems: you understand cascading failure, timeout boundaries, dependency health, and blast radius.
• Regularly contribute to incident mitigation or long\-term fixes (not just closing alerts).
• Can influence through well\-written PRs, documentation, and thoughtful design reviews.
• Hands\-on experience with Cloudflare or a comparable edge/CDN/WAF platform.

• *Nice to have:**

• Experience with Kargo or similar progressive promotion tooling (Argo Rollouts, Flagger).Experience developing or integrating Kubernetes operators.
• Familiarity with service\-level indicators (SLIs), service\-level objectives (SLOs), and structured alerting.
• Building or integrating Kubernetes operators and CRDs.

• *Tools \& Expectations:**

• **Datadog \-** Monitor infrastructure health, capture service\-level metrics, reduce alert fatigue through high signal thresholds.
• **PagerDuty \-** Own incident management pipeline. Route alerts by severity and align with business SLAs.
• **GKE / Kubernetes \-** Improve cluster stability and workload isolation. Define auto\-scaling configurations and tune for efficiency.
• **ArgoCD \-** Keep releases consistent across clusters, monitor sync health, and define safe promotion gates between environments.
• **Helm / GitOps \-** Validate release consistency across clusters. Monitor sync status and rollout safety.
• **Terraform Cloud \-** Support DR planning and detect infrastructure changes through state comparisons.
• **CloudSQL \-** Diagnose DB and networking issues. Monitor latency, enforce access patterns, and validate WAF usage.
• **Cloudflare \-** Manage DNS, WAF, rate limiting and caching; diagnose edge latency and validate security rules.
• **Secret Management \-** Audit access to secrets, apply short\-lived credentials, and define alerts for abnormal usage.
• **Python / Bash** \- Automate toil, build internal tooling, and script diagnostics.

• *We believe the best work happens when we're together, fostering creativity, collaboration, and connection.
