We are a product company building AI-powered mobile applications used by over 10 million people in 150 countries. We own the entire product lifecycle — from the initial idea to large-scale global implementation. We thrive in a fast-paced environment, making data-driven decisions without unnecessary bureaucracy. If you value autonomy, rapid releases, and seeing the direct impact of your work, you will fit right in.
 

The Role

We are looking for a DevOps Engineer to join the team building the infrastructure for our ambitious new project in the Cloud Gaming & Streaming space. You will work alongside our Senior DevOps Engineer to build and scale a high-performance, fault-tolerant system that provisions and streams to a fleet growing from hundreds toward thousands of servers. This is a hands-on role focused on automation, reliability, and fleet operations at scale.
 

Work Format & Relocation

Location: Dubai, UAE (Office).

Trial Period: First 2–3 months are fully remote for a smooth onboarding.

Relocation Support: Full corporate visa sponsorship and relocation support provided after the trial period.
 

Key Responsibilities

• Automate provisioning of bare-metal and virtualized hosts end to end — storage, GPU passthrough, VM lifecycle — across a large, heterogeneous server fleet.
• Build and maintain fleet-scale orchestration: parallel deployment, health checks, and self-healing routines that keep hundreds-to-thousands of machines consistent.
• Develop and harden automation scripts (Bash, Python, PowerShell) that must behave deterministically across servers with differing hardware.
• Manage Linux/KVM virtualization (libvirt/QEMU) and Windows guests, including GPU passthrough and networking.
• Build and maintain configuration management with Ansible to keep fleet hosts and VM images consistent and reproducible.
• Own CI/CD pipelines for infrastructure code and deployment automation, so provisioning scripts, images, and configuration ship in a tested, repeatable way rather than by hand.
• Work with object storage and large-scale content distribution (S3-compatible, e.g. Cloudflare R2).
• Build the observability stack together with the Senior DevOps Engineer — metrics, logging, and alerting across the entire fleet (Prometheus/Grafana or equivalent). You will help design monitoring system from the ground up.
• Own network configuration at fleet scale — NAT, port forwarding, routing, and traffic paths to thousands of concurrent streaming clients.
• Establish secure secrets management (Vault or similar) and sane access practices across the fleet.
• Participate in incident response and on-call rotation to keep a live streaming platform stable.
• Help evolve infrastructure-as-code with Terraform as the fleet grows.
   

Requirements

• Experience: 2+ years in a DevOps / infrastructure role, with exposure to systems running at meaningful scale.
• OS Expertise: Solid Linux administration; working knowledge of Windows administration (or strong willingness to go deep — this project needs both).
• Scripting: Confident with at least one of Bash / Python / PowerShell, and comfortable reading and debugging the others.
• Configuration Management: Hands-on with Ansible for keeping hosts and images consistent.
• CI/CD: Experience building pipelines (GitLab CI, GitHub Actions, or similar) for infrastructure and deployment automation.
• Monitoring: Hands-on experience standing up and running monitoring/alerting (Prometheus, Grafana, Loki/ELK, or similar) — comfortable building it, not just reading dashboards.
• Virtualization: Practical experience with VMs and hypervisors (KVM/libvirt, QEMU, or similar).
• Networking: Solid grasp of Linux networking — NAT, iptables, port forwarding, routing.
• Language: English (Upper-Intermediate or higher, sufficient for technical collaboration).
   

Nice-to-have

• Experience operating server fleets (dozens+) and writing idempotent, restart-safe automation.
• GPU passthrough / vfio, or experience with GPU-heavy workloads.
• Object storage at scale (S3/R2) and large-file distribution.
• Experience building an observability stack from scratch on a large fleet.
  Secrets management at scale (Vault, SOPS, or similar).
• Familiarity with Terraform.
• Exposure to the streaming or gaming field, or an understanding of data streaming principles.

• Basic knowledge of C++ or C# to collaborate effectively with the core infrastructure team.

  
  What We Offer

• Greenfield Ownership: The monitoring and observability stack does not exist yet — you will help design and build it from zero, shaping how we see our entire fleet.
• Growth: Work directly with a Senior DevOps Engineer on a greenfield platform — a strong path to grow your fleet-scale and virtualization expertise.
• Relocation Package: Full financial and organizational support for your move to Dubai (visa, tickets, initial housing) after the trial period.
• Modern Office: Work from a vibrant, tech-driven workspace in Dubai.
• Real Impact: Direct influence on the tech stack of a Cloud Gaming platform with a potential million-user audience.
• Fast-Paced Culture: A product-driven environment where decisions are made quickly, without micromanagement.
• Compensation: Competitive salary pegged to USD (to be discussed individually based on technical interview results).

• Develop and operate workloads on our lakehouse platform (Databricks / Spark / Delta) and our data warehouse (Redshift), including migrating existing pipelines from the warehouse to the lakehouse
• Orchestrate pipelines with Airflow: scheduling, dependencies, retries, backfills and alerting
• Prove correctness, not just completion: design parity checks and reconciliation queries when replacing an existing pipeline, run large historical backfills, and investigate data discrepancies down to the row level
• Build and maintain Python services and REST APIs that serve data to internal products
• Optimize for performance and cost: query tuning, table design, workload management and right-sizing compute
• Own what you ship: monitor production pipelines, participate in incident triage and root-cause analysis, and harden systems so the same failure does not happen twice
• Collaborate cross-functionally with product managers, data scientists and stakeholders across the company to deliver on product roadmap
• Work within an Agile team that releases cutting-edge new features regularly
• Take a high degree of ownership and freedom to experiment with new technologies to improve our software
