شرح موقعیت شغلی

We are looking for a Senior Cloud Data Center Network Infrastructure Engineer to design, operate, and scale the network and infrastructure backbone that powers our video streaming platform. You will own the connectivity, reliability, and performance of an estate spanning 3 datacenters, 500+ Ubuntu virtual machines, and a cloud-native application platform that delivers high-quality video to viewers at scale

Streaming is a demanding workload: high sustained throughput, low latency, sensitivity to jitter and packet loss, and traffic that can spike sharply around live events and popular releases. This role is central to keeping that experience smooth — from the inter-datacenter backbone to the edge, and from storage I/O for content to the routing that gets every stream to the viewer.

This is a hands-on, senior-level position for someone who is equally comfortable troubleshooting a BGP route flap, writing an Ansible playbook to roll out a change across hundreds of hosts, and sitting in an architecture review to plan the next year of capacity. You'll be a technical anchor for the team and a go-to person for complex network and infrastructure challenges.

What You'll Do

  • Design, deploy, and maintain network infrastructure across 3 datacenters, including inter-DC connectivity, redundancy, and failover.
  • Configure and manage BGP peering and routing between datacenters and external providers, ensuring resilient, optimized path selection.
  • Build and operate multiple tunneling connections (e.g. IPsec, GRE, VXLAN) across broadband, LAN, and WAN links.
  • Administer and optimize Cisco Nexus switching fabrics, including VPC, spine-leaf topologies, and VLAN/segmentation strategy.
  • Manage and harden FortiGate firewalls — policy design, VPN termination, segmentation, and security posture.
  • Operate and scale a fleet of 500+ Ubuntu virtual machines, including provisioning, patching, monitoring, and lifecycle management.
  • Implement and maintain Infrastructure as Code using Ansible — automating configuration, deployments, and repeatable change across the estate.
  • Support and integrate software-defined storage (SDS) solutions for capacity, performance, and the high-throughput I/O demands of video content.
  • Engineer the network for high-bandwidth, low-latency video delivery — capacity planning, QoS, traffic shaping, and prioritization of streaming traffic.
  • Optimize content delivery and edge connectivity, including CDN integration and peering/interconnects with ISPs and IXPs for efficient last-mile delivery.
  • Plan and absorb traffic spikes from live events and high-demand releases, ensuring elastic scaling and graceful degradation under load.
  • Support cloud-native application platforms, including Kubernetes networking (CNI, ingress, service mesh, network policy) for streaming and transcoding workloads.
  • Monitor stream quality and network health (latency, jitter, packet loss, throughput), lead root-cause analysis for incidents, and drive continuous improvement.
What You'll Bring (Required)

  • 5+ years of experience in network and/or cloud infrastructure engineering, with senior-level ownership of production environments.
  • Deep, hands-on expertise with BGP and complex routing in multi-site environments.
  • Strong experience with Cisco Nexus switching and data center network design (spine-leaf, VPC, VLANs, segmentation).
  • Proven experience administering FortiGate firewalls — policies, VPNs, and tunneling (IPsec/GRE/VXLAN).
  • Solid command of Linux (Ubuntu) server administration at scale (500+ hosts).
  • Practical experience with Ansible and an Infrastructure-as-Code approach to configuration and change management.
  • Working knowledge of Kubernetes and cloud-native networking concepts.
  • Familiarity with software-defined storage technologies.
  • Strong understanding of LAN/WAN networking, broadband connectivity, and high-availability design.
  • Experience engineering networks for high-throughput, latency-sensitive workloads (video streaming, media delivery, or similarly demanding real-time traffic).
  • Excellent troubleshooting skills and a calm, methodical approach to incidents.
Nice to Have

  • Industry certifications such as CCNP / CCIE, Fortinet NSE, CKA / CKAD, or relevant Linux certifications.
  • Experience with monitoring and observability stacks (e.g. Prometheus, Grafana, ELK).
  • Hands-on experience with CDNs (e.g. Cloudflare, Akamai, Fastly, or a self-hosted CDN) and edge caching strategies.
  • Familiarity with streaming protocols and media delivery (HLS, DASH, RTMP, SRT, WebRTC) and how they shape network requirements.
  • Experience with multicast routing and/or large-scale live-event delivery.
  • Exposure to additional automation/IaC tooling (Terraform, GitOps workflows).
  • Experience with service mesh (Istio, Linkerd) and advanced Kubernetes network policy.
  • Familiarity with storage platforms such as Ceph or equivalent SDS solutions.
  • On-call / 24x7 production support experience.

معرفی شرکت

در فیلم‌نت، هر روز تلاش می‌کنیم تا به اهداف بزرگ‌تری دست پیدا کنیم. سال 93، زمانی که مفهوم VOD چیزی بیش از یک رویا نبود، ما سفرمان را آغاز کردیم. مدیران مجموعه رویای ساخت و ارائۀ سرویسی را داشتند که با استفاده از آن تمام مردم ایران از هر منطقۀ جغرافیایی و در هر زمان قادر به تماشای محتوای موردنظر خود باشند.
با تجربه‌هایی که در این راه کسب کردیم، چابک تر شده‌ایم و در حال بازسازی سازمان، انتخاب دقیق شرکای خود و ساخت مجموعه‌ای مستحکم از استعدادها، توانایی‌ها، هنرمندان و ارزش‌ها هستیم. ما اینجاییم تا آینده‌ای جدید برای این صنعت رقم بزنیم و ارائه‌دهندۀ کیفیت حقیقی، شور و اشتیاق و چشم‌اندازی جذاب برای کاربران، همکاران و شرکای‌مان باشیم.
فیلم‌نت همیشه از همکاران خلاق و متعهد، ایده‌های جدید، شروع دوباره، مشتریان و شرکای جدید استقبال می‌کند. در کنار شما خواهیم بود تا تجربه ای از VOD بسازیم که ارزش اعتماد شما را دارد؛ تا بتوانیم از آنچه که با هم خلق کرده‌ایم، برداشت کنیم و آن را به بازار جهانی عرضه کنیم.
