Generative AI Engineer

About Virtasant

Virtasant is a global technology services company with a network of over 4,000 technology professionals across 130+ countries. We specialize in cloud architecture, infrastructure, migration, and optimization, helping enterprises scale efficiently while maintaining cost control.

Our clients range from Fortune 500 companies to fast-growing startups, relying on us to build high-performance infrastructure, optimize cloud environments, and enable continuous delivery at scale.

About the role

Our client develops a powerful AI-powered training and communication SaaS platform that gives frontline workers the knowledge they’re missing to drive measurable business performance.

You will be a fully remote , hands-on contributor on our client's Development Team, building features and products primarily across Agentic AI and backend services , with occasional contributions to frontend user interfaces when needed. This role takes clear ownership of well-defined problems and delivers high-quality solutions with confidence and independence. Working closely with peers across the Development Team, you will contribute to technical discussions, keep pace with a fast-moving codebase, and bring genuine care for the craft to everything you build.

What You’ll Do

• Design, develop, test, deploy, and support high-quality code:
• Building, running, and consuming MCP servers (tool design, auth/OAuth, multi-tenant security, deployment)
• Building LLM agents with tool/function calling and multi-agent orchestration (e.g., A2A or similar)
• Testing and evaluating agent behaviour, plus observability in production
• Contribute to architecture and design discussions, and help evaluate trade-offs around scaling, reliability, and maintainability.
• Develop backend services in Python (for AI and Agent work) and Java (for integrating with our client's core platform), with attention to performance and data quality.
• Use AI coding tools (e.g., Cursor, Claude Code, GitHub Copilot) as part of your daily workflow to improve productivity and code quality.
• Participate in code reviews, giving and receiving feedback that improves the quality and consistency of the codebase.
• Identify and flag technical debt, and contribute ideas for how to address it.
• Break down development tasks into clear, manageable pieces and execute them reliably.
• Collaborate with Product Management and Quality Assurance to refine requirements and ensure your work meets a high bar for quality.
• Share what you're learning — whether that's a new pattern, a tool, or a better way of doing something — with the people around you.
• Other relevant duties as required.

What We’re Looking For

Must-Have Experience

• Be based in Brazil, Colombia, the Dominican Republic, or Mexico.
• Strong level of English, written and spoken.

• Hands-on experience with AI coding assistants (such as Cursor, Claude Code, or GitHub Copilot) as part of a daily development workflow.
• Familiarity with cloud platforms (especially GCP) and application infrastructure concepts — containers, caching, and distributed systems — is an asset.
• Experience working with Microservices
• Comfortable working independently on well-defined problems and seeing them through to completion.
• Strong attention to detail and a commitment to unit and functional testing.
• Experience building AI-driven applications, agentic products and features, working with LLMs, or using frameworks like LangChain or Google ADK:
• Hands-on production experience building, running, and consuming MCP servers, including tool design, auth/OAuth, multi-tenant security, and deployment.
• Building LLM agents with tool/function calling and multi-agent orchestration (e.g., A2A or similar)
• Testing and evaluating agent behaviour, plus observability in production
• Computer Science, Engineering, or similar technical aptitude gained through post-secondary education, hands-on experience, or both.
