What are Senior Full Stack Java Developers?

Senior Full Stack Java Developers are experienced software professionals who design, develop, and maintain both the front-end and back-end components of web applications using Java and related technologies. They typically work with frameworks such as Spring Boot for the backend and may use JavaScript frameworks like Angular or React for the frontend.

Job description

Senior Full Stack Developer - ERP & AI Systems

ITPS Canada Ltd. - London, Ontario


Build the system that runs a flight school.


ITPS is developing a Flight School Management System (FSMS) - a full-scale ERP platform that powers our training operations, flight and simulator scheduling, maintenance tracking, and procurement workflows.

This is not a typical web app. It's a mission-critical operational system used in a real-world aviation environment.

We're looking for a senior full stack developer who wants to take ownership of a complex system, shape its architecture, and help us integrate AI-driven capabilities into day-to-day operations.


What You'll Work On

You'll be building and evolving a multi-module ERP platform that includes:

  • Flight & simulator scheduling (high-constraint, real-world logistics)
  • Training and student progression tracking
  • Maintenance planning and compliance workflows
  • Procurement and operational support systems
  • Cross-system integrations (financial, scheduling, communications)


You'll also help introduceAI-enabled features, such as:

  • Intelligent scheduling assistance and conflict detection
  • Automated report generation and data summarization
  • Natural language interaction with operational data
  • Workflow automation and decision support tools


Your Role

  • Design and implement end-to-end features across the stack
  • Architect scalable backend services and data models
  • Build responsive, data-rich frontend interfaces
  • Work directly with stakeholders (operations, maintenance, training) to translate real-world needs into software
  • Own system quality: performance, reliability, and maintainability
  • Contribute to technical direction, architecture, and tooling decisions
  • Integrate AI capabilities into production workflows


Tech Stack

  • Backend: PHP (Laravel)
  • Frontend: React, JavaScript (ES6+), HTML, CSS
  • Database: MySQL
  • Tools: Git (Gitea / Perforce), FullCalendar
  • Integrations: REST APIs, Microsoft Graph


What We're Looking For


Core Experience

  • Strong experience building and shipping full stack applications in production
  • Deep proficiency with:
    • PHP (Laravel)
    • React / modern JavaScript
    • Relational databases (MySQL or similar)
  • Experience designing APIs and integrating external systems
  • Ability to think in terms of systems, not just features


AI & Modern Development

  • Experience integrating AI tools or APIs into applications (OpenAI, Claude, etc.)
  • Comfort using AI-assisted development workflows
  • Interest in applying AI to real operational problems (automation, decision support)


Mindset

  • Product-minded: you care how the system is used, not just how it's built
  • Strong ownership: you can take a problem from concept to production
  • Comfortable working across domains and with non-technical stakeholders
  • Pragmatic and adaptable in a growing system


Nice to Have

  • Experience with ERP, scheduling, or operations platforms
  • Experience with financial or procurement systems
  • Familiarity with Linux / Bash
  • Experience in aviation, aerospace, or safety-critical environments
  • Exposure to Node.js or mobile development


Why This Role

  • Real-world impact - your work directly supports flight operations and safety
  • High ownership - influence architecture, product direction, and system design
  • Complex problems - scheduling, logistics, and multi-domain workflows
  • AI opportunity - help define how AI is applied in an operational environment
  • Stable + meaningful domain - aviation training and operations


How to Apply

If you're interested, send us:

  • Your resume
  • A brief note on systems you've built or owned
  • (Optional) Examples of AI integration or automation you've implemented


Final Note

We're not looking for someone to just execute tickets.

We're looking for someone who wants to build and own a system that matters.

AI Disclosure:We may use artificial intelligence tools to assist with scheduling interviews and managing screening times. We do not use AI to evaluate applicants or make decisions during the interview process. All candidate assessments and hiring decisions are made by our recruitment and leadership teams.
