Description

About ITRex

THE PLACE

ITRex - AI pioneers who build systems that actually work in the real world, not just in demos. We're 200+ people spread across the US and Europe, creating solutions for companies like P&G and Shutterstock. We keep it simple, build it right, and focus on what works.

THE PEOPLE

We're the kind of people who don't ignore messages in Slack, who jump in to help when you're stuck on a problem, and who offer solutions instead of blame when things go sideways. We believe in openness, accountability, and having each other's backs. No office politics, no hidden agendas - just people who care about doing good work together and supporting each other to get there.

About the job

We are seeking a skilled Senior Build & Release Engineer, who will implement and maintain end-to-end CI/CD pipelines using GitHub, with a strong focus on test-driven deployment, automated release management, and Infrastructure as Code (IaC) practices.

The ideal candidate will containerize services using Docker, manage build, compilation, and publishing workflows for JavaScript, TypeScript, and C++ packages, and design robust multi-language build pipelines leveraging CMake or similar build tools.

The role also includes automating build, tagging, and publication processes across web, desktop, and mobile platforms to ensure consistent and traceable releases. Deep expertise in networking, and IaC tools is essential to deliver scalable, secure, and highly available deployments.

Your Responsibilities

• Lead the design, architecture, and management of CI/CD pipelines using GitHub Actions (and similar tools), ensuring fast, reliable, and reproducible software delivery
• Implement and enforce test-driven deployment systems, integrating automated testing, validation, and monitoring to maintain code quality and accelerate feedback cycles
• Containerize applications and microservices with Docker, optimize image builds, and manage deployment pipelines for distributed environments
• Oversee the build, packaging, and publishing lifecycle for JavaScript, TypeScript, and C++ packages, including versioning, semantic tagging, and NPM or internal registry publication
• Develop and maintain cross-platform build pipelines using CMake, NPM or equivalent tools, ensuring consistent compilation and release workflows across web, desktop, and mobile
• Automate end-to-end release processes, including tagging, building, signing, and distributing mobile, web, and desktop applications
• Define and manage Infrastructure as Code (IaC) to provision and maintain reliable, scalable, and secure infrastructure environments
• Collaborate closely with development, QA, and operations teams to troubleshoot deployment issues, optimize performance, and improve release reliability
• Continuously improve observability and feedback loops, leveraging monitoring and alerting systems to maintain operational excellence

Requirements

• 5+ years of hands-on experience in a DevOps, CI/CD, or Release Engineering role
• Strong knowledge of AWS/Azure/GCP cloud, Infrastructure as Code (Terraform/Terragrunt), shell scripting
• Knowledge of Docker, including image creation, registry management, and basic orchestration patterns
• Hands-on experience with compilation and publishing workflows for JavaScript, TypeScript and C++ packages
• Proven experience in designing, architecting, and maintaining CI/CD pipelines, preferably using GitHub Actions (or similar tools)
• Experience with cross-platform build and release automation (web, desktop, and mobile)
• Experience in automating tagging, versioning, signing and artifact distribution processes
• Experience managing Release workflows across web, desktop, and mobile, for cloud and on-premise systems
• Ability to design robust multi-language build pipelines leveraging CMake or similar build tools
• Experience in integration of automated testing, validation, and monitoring
• English level: B2 or higher
  

Nice to have

• Coding experience, especially in C++, JavaScript, and TypeScript
• Deep understanding of C++ build systems, especially CMake
• Experience building and supporting AI/ML pipelines (training and deploying models) using PyTorch or TensorFlow
• Strong Linux system administration and networking skills
• Experience setting up monitoring and alerting systems
• Familiarity with tools like Prometheus, Grafana, or ELK for CI/CD processes tracking
• Background in secure environments like fintech, blockchain, or distributed systems
