DevOps Engineer

Medium Level

Location: United States or Turkey only. We do not hire outside these countries.

What you will deliver (first 90 days)

  • Infrastructure as Code baseline for at least two client environments with Terraform modules and drift detection.
  • CI/CD pipelines (GitHub Actions or GitLab CI) with build-to-prod lead time <30 minutes and one-click rollback.
  • Observability stack live: logs, metrics, traces, and alerts for the four golden signals; on-call runbook published.
  • SLOs set for critical services (target ≥99.9%); incident MTTR <30 minutes for P1 after playbooks go live.
  • Secrets and IAM hardened: no secrets in repos, least-privilege roles, automated rotation.
  • Cost controls: 90%+ tag coverage, budgets and alerts, and a documented 10–20% monthly cost reduction plan.
  • Backup and DR: RPO/RTO defined, backups verified with at least one restore test per environment.

Responsibilities

  • Build and maintain cloud infrastructure (AWS or GCP preferred) using Terraform and GitOps workflows.
  • Own CI/CD: artifact management, environment promotion, canary/blue-green, and automated rollback.
  • Run Kubernetes or container platforms (EKS/GKE) including Helm/ArgoCD, autoscaling, and networking.
  • Implement observability: OpenTelemetry/Prometheus/Grafana/ELK, alert routing, SLOs, and incident response.
  • Secure the stack: network policy, IAM, secrets management (SSM/Secrets Manager/Vault), image and dependency scanning, SBOMs.
  • Optimize cost: rightsizing, lifecycle policies, savings plans/RIs, storage tiers, usage reports to stakeholders.
  • Standardize environments: dev/stage/prod parity, ephemeral preview environments, reproducible builds.
  • Document everything: runbooks, architecture diagrams, readiness/DoD/DoR checklists.
  • Collaborate with product, QA, and engineering; support sales with accurate assumptions and effort ranges.

Requirements

  • 4+ years as DevOps, SRE, or Platform Engineer at a startup or agency.
  • Expert with Terraform and Git; comfortable reviewing plans and enforcing policy-as-code.
  • Strong with containers and orchestration (Docker, Kubernetes) and service networking (ingress, DNS, TLS).
  • CI/CD proficiency: GitHub Actions or GitLab CI, artifact registries, caching, and pipeline optimization.
  • Observability skills: metrics, logs, traces, alerting, and on-call hygiene.
  • Security fundamentals: IAM, secrets, image scanning, supply-chain controls.
  • Scripting ability in Bash and one higher-level language (Python, Go, or Node.js).
  • Solid networking and Linux fundamentals.
  • Time-zone overlap: minimum 4 hours with Pacific Time or Türkiye time, depending on team.
  • Based in the United States or Turkey.

Nice to have

  • ArgoCD/Flux, Helm, Kustomize; service mesh (Istio/Linkerd).
  • FinOps experience and unit economics reporting.
  • SOC 2/ISO 27001 readiness work.
  • Data platform operations (Airflow/DBT/warehouse) or mobile CI (Flutter/React Native).
  • Edge/IoT deployment pipelines and OTA update systems.

How we work

  • Two-week sprints, trunk-based development, small PRs, frequent releases.
  • Everything as code. Changes flow through PRs with automated checks.
  • Blameless postmortems and action items with owners and dates.

What to include in your application

  • Resume or LinkedIn.
  • A small Terraform module or pipeline snippet you wrote (redact secrets).
  • A short note on an incident you resolved or a cost reduction you achieved, with metrics and the playbook you used.
