Overview

We are seeking a Senior Infrastructure Engineer with deep experience in cloud infrastructure, Linux internals, large-scale distributed systems, workload isolation, and a strong security mindset to join our team and help design, build, and operate a global, resilient platform.

  • Manage and provision AWS infrastructure using Terraform and Kubernetes
  • Write and maintain Kubernetes manifests and deployment configurations for critical workloads, including pod security contexts, anti-affinity rules, network policies, autoscaling, and health probes
  • Drive Production Readiness Reviews (PRR) for all new services, covering security, HA, performance, and observability gates
  • Design and operate multi-layer workload isolation using Linux kernel primitives: namespaces (pid, net, mnt, user, uts, ipc), cgroups, seccomp profiles, and capabilities, as the baseline security boundary
  • Evaluate and operate gVisor and Firecracker for workloads requiring hard tenant boundaries and near-native performance
  • Design and maintain Grafana dashboards
  • Manage Prometheus and VictoriaMetrics pipelines; define and tune P1/P2/P3 alert thresholds with runbooks

Required Qualifications:
  • 5+ years of experience in infrastructure, SRE, or platform engineering roles
  • Expertise in distributed systems and cloud-native architectures
  • Understanding of Linux internals: namespaces, cgroups, seccomp, capabilities, and system-level performance tuning
  • Experience operating infrastructure on AWS at scale
  • Proficiency in Terraform and Kubernetes, including security hardening of manifests
  • Experience designing and running load tests (k6, Gatling, Locust, or similar)
  • Understanding of network security and cloud security best practices
  • Excellent analytical, troubleshooting, and communication skills
