  • Build and maintain hybrid networking solutions with secure, low-latency connectivity.
  • Implement reliability-focused practices including autoscaling, load balancing, disaster recovery, and fault-tolerant system designs.
  • Define and enforce DevSecOps policies, including secrets management, RBAC, Pod Security Standards, and secure container runtimes.
  • Build, monitor, and maintain CI/CD pipelines with automated testing gates for security, performance, and reliability.
  • Deploy and manage observability stacks (Prometheus, Grafana, Loki, OpenTelemetry) to define SLOs/SLIs, alerts, and dashboards.
  • Lead incident response, root cause analysis, postmortems, and continuous reliability improvements.
  • Participate in on-call rotations to ensure 24/7 system availability and quick resolution of production issues.
  • Optimize cost, performance, and security across AWS services and on-prem resources.
  • Harden Linux servers and infrastructure with security best practices (firewalls, SELinux/AppArmor, TLS/mTLS).
  • Integrate vulnerability scanning for containers, IaC, and dependencies into operational workflows.
  • Collaborate with developers to improve system reliability, operational efficiency, and secure application design.

Your Skills and Experience

Must-Have

  • Expertise in AWS services (VPC, EC2, IAM, CloudWatch, EKS, ElastiCache, MSK).
  • Proficiency in Terraform, Ansible, and infrastructure as code principles.
  • Solid knowledge of CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins) with a focus on operational reliability and security.
  • Deep understanding of Linux internals, networking (iptables, nftables, routing), and security hardening.
  • Strong observability skills: Prometheus, Grafana, Loki, OpenTelemetry.
  • Experience supporting high-availability, high-concurrency production systems.
  • Experience in incident management, postmortems, and continuous improvement of reliability metrics.
  • Willingness to participate in on-call rotations to ensure 24/7 system uptime.

Nice-to-Have

  • Experience with Redis and Kafka in production at scale.
  • Familiarity with secure networking automation and compliance frameworks.
  • Knowledge of DevSecOps practices, Vault, IAM policy enforcement, and vulnerability management.
