Responsibilities

ABOUT THE POSITION

We are looking for a Backend Machine Learning Programmer to build the scalable services and data infrastructure that power our AI products. You will design cloud-native systems on AWS, build large-scale data pipelines, and deploy and serve machine-learning models in production. You will join the team advancing AI-assisted coding and agentic approaches across Virtuos - creating AI agents and solutions that make our developers more productive - alongside our work, to a smaller degree, on real-time AI, game AI, and quality-engineering agents. This is a global Virtuos role. Being based in our Kuala Lumpur office is a plus but not required. On-site presence is expected at the start, and a hybrid arrangement (three days in the office, two days from home) can be agreed after an initial on-site period. A fully remote arrangement is not offered for this role. We're happy to discuss individual circumstances and reasonable accommodations within this arrangement.

• Design and build scalable backend services and APIs for machine-learning and AI features.
• Build and operate large-scale data pipelines for ingesting, processing and storing big datasets.
• Deploy, serve and scale machine-learning models in production, including inference, embeddings and vector search.
• Design and operate cloud infrastructure on AWS, ensuring reliability, security and cost-efficiency.
• Own data storage and retrieval across relational and vector/search stores.
• Build CI/CD, observability and automated testing for backend systems.
• Collaborate with machine-learning and frontend engineers to deliver features end to end.
  
  
  

• Strong backend engineering skills in Python (and/or another server-side language).
• Hands-on experience with AWS cloud services (compute, storage, containers and serverless).
• Experience with big-data and distributed-data processing at scale.
• Experience serving machine-learning models and working with databases, including vector/search stores.
• A solid grounding in APIs, microservices, containerization and monitoring.
• Experience with CI/CD pipelines - GitLab and Horde are a strong plus; Jenkins and TeamCity a lesser plus.
• Game development experience is valued.
• Bachelor's degree in Computer Science, Engineering or equivalent experience.
• Excellent written and spoken English.
• Around 4+ years of backend engineering experience.
• Hands-on experience with AI coding assistants such as Claude Code, Codex CLI, GitHub Copilot or equivalent (required).
