Job description

About Virtasant Virtasant is a global technology services company with a network of over 4,000 technology professionals across 130+ countries. We specialise in cloud architecture, infrastructure, migration, and optimisation, 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, optimise 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 spanning backend services and frontend user interfaces. 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 across both backend services and frontend user interfaces.
• Contribute to architecture and design discussions, and help evaluate trade‑offs around scaling, reliability, and maintainability.
• Build robust user interfaces using HTML5 technologies (HTML, CSS, JavaScript ES2017, TypeScript, React) across browsers and platforms.
• Develop backend services (Java, GoLang) that make up our client's core solution, 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 a Latin American country.
  • Strong level of English, written and spoken.
  • 4+ years of full-stack software development experience with modern frontend frameworks and backend services.
  • Solid experience with React and TypeScript; familiarity with JavaScript design patterns and single-page apps.
  • Solid experience in Java and/or GoLang, including working with data structures, relational databases (MySQL is preferred), and SQL.
  • 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.
  • Familiarity with cloud platforms and application infrastructure concepts - containers, caching, and distributed systems - is an asset.
  • Experience building AI-driven applications, agentic products and features, working with LLMs, or using frameworks like LangChain or Google ADK is considered a strong asset.
  • Computer Science, Engineering, or similar technical aptitude gained through post-secondary education, hands‑on experience, or both.
