Java Backend Engineer – AI

About the role

Capco is hiring a Java Backend Engineer in Toronto who builds scalable backend applications and integrates AI-powered workflows into complex financial services environments. The role combines strong Java backend engineering with hands-on AI development: building services, integrating Large Language Models (LLMs) and AI capabilities into enterprise applications, and developing intelligent workflows that improve operational efficiency. It works closely with business stakeholders, architects and technology teams.

Key responsibilities

• Design, develop, test and maintain scalable backend applications and microservices using Java and Spring Boot.
• Build AI-powered applications, workflows and automation solutions using LLMs, AI APIs and capabilities such as structured outputs and tool calling.
• Develop REST APIs and integrate AI capabilities with enterprise applications, data sources and business processes.
• Use AI-assisted development tools such as GitHub Copilot, Cursor, Devin or equivalent to speed up coding, testing, debugging and delivery while keeping engineering standards.
• Own technical deliverables from design through implementation, testing, deployment and production support, working with stakeholders to resolve complex problems.

Required profile

• 4-6 years of hands-on software development experience with strong Java and backend application development.
• Practical experience building AI-enabled applications or workflows using LLM APIs, prompt engineering, structured outputs or tool/function calling, beyond using AI coding assistants alone.
• Experience with automated testing, CI/CD, version control, troubleshooting and end-to-end delivery, including AI evaluation, output validation, guardrails, privacy and security.

Required skills

• Java and Spring Boot
• REST APIs and microservices
• AI-assisted development tools such as GitHub Copilot, Cursor or Devin
