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

Qualifications:

• Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
• 7+ years of work experience as a data engineer
• Proficiency in Python and using it as the primary development language in recent years
• Expert-level SQL: comfortable writing, reading and tuning complex analytical queries against very large tables, and debugging why two result sets disagree
• Hands-on experience with a distributed data processing platform (Spark/Databricks strongly preferred; EMR, Snowflake or BigQuery also relevant) and with a columnar data warehouse (Redshift, Snowflake, BigQuery, ClickHouse, etc)
• Ability to design complex data models: normalized, dimensional and temporal (slowly changing dimensions, effective-dated records, point-in-time correctness)
• Experience with workflow orchestration tools (Airflow or similar): building DAGs, managing dependencies and running backfills
• Experience integrating third-party data feeds: handling schema drift, late or missing deliveries, vendor data-quality defects and versioned reference data
• Experience building REST services in Python (FastAPI, Flask, etc)
• Experience developing, maintaining, and debugging problems in large server-side code bases
• Working knowledge of AWS (S3, IAM, ECS or similar compute) and Docker
• Good knowledge of engineering best practices and testing (unit test, integration test, code review, CI/CD)
• The desire to take a high level of ownership of the things you work on
• Ability to learn new things quickly, maintain a high bar for quality, and be pragmatic
• Must be able to communicate with U.S based teams
• Experience with Delta Lake / medallion lakehouse architectures is a plus
• Experience migrating legacy pipelines between platforms with strict parity requirements is a plus
• Experience with advertising, media or measurement industry data is a plus
• Ability to communicate effectively with the U.S.-based teams and work 11:00 AM — 8:00 PM EEST (11:00 - 20:00).

Our Tech Stack:

• Almost everything we run is on AWS (S3, ECS, EMR, RDS and more)

Simulmedia is seeking an experienced Senior Backend Engineer to join our engineering team, working on the backend and data infrastructure powering our TV advertising platform - spanning National Linear and CTV. This role sits within a distributed system of up to ~30 microservices, and you'll be primarily responsible for building, scaling, and operating backend services - with secondary exposure to backend-for-frontend work in TypeScript/Node.

In this role you will work closely with product managers, designers, and data engineers to ensure seamless integration of analytics features into the platform. The ability to frequently iterate and deliver high-quality features that are owned end-to-end is crucial in this role.

We're looking for someone who takes ownership, communicates directly and honestly, and cares about the reliability and craft of the systems they build - not just shipping features but understanding how they behave in production.

Location: Ukraine is mandatory. Our offices are located in Kyiv and Lviv. Teams are located in Kyiv and Lviv and primarily work remotely with occasional offline meetings.

Key Responsibilities:

• Design, build, and maintain backend services in Ruby (Roda) operating within a large-scale distributed microservice architecture.
• Contribute to backend-focused TypeScript/Node.js work, including API design and tRPC procedures, in support of Next.js applications.
• Own service reliability: instrumentation, monitoring, and observability across services (tracing, metrics, structured logging).
• Collaborate closely with data engineers on data pipelines, ETL processes, and ensuring clean, well-modeled data flows between services.
• Investigate and resolve production incidents; contribute to and follow oncall/runbook practices.
• Design and evolve APIs with strong attention to authentication, authorization, and security best practices.
• Participate in code reviews, pair programming, and knowledge-sharing sessions to ensure high-quality, maintainable code.
• Write thorough unit and integration tests for backend services
• Work independently while communicating clearly across a distributed, cross-functional team

Qualifications:

• Bachelor’s degree in Computer Science, Computer Engineering, or a related technical field.
• 5+ years of professional Ruby backend development experience; prior experience may be with Rails, Roda, Sinatra, or similar - deep Roda-specific knowledge is not required, as long as the underlying Ruby fundamentals are strong.
• Experience operating within a distributed systems / microservice architecture.
• Solid working knowledge of observability tooling - OpenTelemetry, Datadog, Grafana, Prometheus, or equivalent - including setting up tracing, metrics, and alerting, not just consuming dashboards.
• Experience with error tracking/monitoring tools such as Sentry, Honeybadger or equivalent.
• Hands-on experience in TypeScript and Node.js, with practical experience in Next.js for backend/API-layer work.
• Experience with tRPC or comparable typed API frameworks.
• Solid experience with AWS and its core services (e.g. EC2, S3, RDS, SQS/SNS, ECS/EKS), including infrastructure-as-code with AWS CDK, plus containerized applications (Docker).
• Experience designing and evolving APIs, including auth, security, and versioning concerns.
• Experience working in a large distributed system with dozens of independent services, potentially written in different languages; ability to quickly get up to speed in unfamiliar code and trace a request's path across multiple services end-to-end.
• Experience with CI/CD pipelines - we currently use Jenkins and are actively migrating to GitHub Actions, so comfort with either (and ideally migration experience) is valuable.
• Ability to use AI coding tools (e.g. Claude Code, Codex, Cursor, or similar) effectively to speed up development, debugging, and code comprehension.
• Strong communication skills; ability to work independently and take ownership of services end-to-end.
• Ability to communicate effectively with the U.S.-based teams and work 11:00 AM - 8:00 PM EEST (11:00 - 20:00).

Bonus Points for:

• Python experience (data tooling, scripting, or services)
• Experience in AdTech or digital advertising/media analytics
• Prior experience in a service migration, decomposition, or platform-modernization effort
