Job Title: Lead Java Engineer / Staff Software Engineer
Location: Downtown Toronto, ON (Hybrid)
Hire Type: Full time


We are seeking a strong Lead/Staff Java Engineer with deep backend engineering, architecture, and system design expertise. The candidate will be hands-on with implementation while contributing significantly to technical architecture and platform development.

  • Hands-on experience with greenfield/0-to-1 development.
  • Ability to select appropriate frameworks, technologies, and architectural patterns for new platforms.
  • Strong hands-on coding and implementation skills.
  • Experience with AWS cloud services.
  • Experience with event-driven and distributed architectures.
  • Familiarity with edge computing/CDN technologies is highly desirable.
  • Experience leveraging AI-assisted development tools such as GitHub Copilot and LLM-based coding workflows.
  • Strong understanding of CI/CD, observability, security, and scalable platform engineering.
  • Excellent communication skills and the ability to influence technical decisions.
  • Must be comfortable asking questions, challenging assumptions, and clarifying requirements rather than simply accepting them.
