Senior Java Developer jobs in Stouffville, ON

Senior Software Engineer (Laravel/PHP, Node.js, React)

About the Role

We are looking for a Senior Software Engineer to own the technical direction of our web platform and lead a small development team of 2–4 engineers. This is a hands-on leadership role where you will combine deep technical expertise with strategic thinking — writing production code daily while shaping architecture, mentoring developers, and driving delivery.

The ideal candidate is someone who has fully embraced AI-assisted development (Claude Code, Cursor, Copilot, or equivalent) and can confidently deliver production-quality code at high velocity using these tools. You don’t just use AI as autocomplete — you architect solutions through AI, review AI-generated output critically, and multiply your team’s throughput.

Technical Leadership

• Own the technical architecture and make key technology decisions across the full stack
• Conduct impact analysis before implementing changes — assess risk, dependencies, regressions, and
• downstream effects
• Establish and enforce coding standards, code review processes, and engineering best practices
• Drive technical debt reduction and system reliability improvements
• Provide wide-lens visibility across the entire codebase — understand how components interact and where changes ripple

Team Leadership

• Lead a small team of 2–4 developers, providing mentorship and day-to-day guidance
• Conduct code reviews with a focus on teaching, not gatekeeping
• Break down large features into well-scoped tickets with clear acceptance criteria
• Shield the team from ambiguity — translate business requirements into actionable technical tasks
• Foster a culture of ownership, quality, and continuous improvement

AI-Powered Development

• Write production code confidently and efficiently using AI coding tools (Claude Code, Cursor, GitHub
• Copilot, or equivalent)
• Demonstrate the ability to deliver 100% of code output through AI-assisted workflows while maintaining
• quality, security, and correctness
• Establish AI-assisted development workflows and best practices for the team
• Critically evaluate AI-generated code for security vulnerabilities, edge cases, and architectural fit
• Stay current with AI tooling advancements and integrate them into the team’s workflow

Requirements

Must Have

• 7+ years of professional software development experience
• 2+ years in a tech lead or senior engineering role with direct team leadership
• Strong full-stack proficiency: backend (PHP/Laravel, Node.js), frontend (Vue.js, React, or equivalent), databases (MySQL/PostgreSQL, Redis)
• Proven experience with AI-assisted development tools — must be able to demonstrate fluent, confident AI-driven coding workflow
• Deep understanding of impact analysis: ability to assess how changes affect the broader system before writing a single line of code
• Experience with Docker, Kubernetes, CI/CD pipelines, and cloud infrastructure (AWS, GCP, or equivalent)
• Strong understanding of REST API design, authentication/authorization, and security best practices
• Excellent communication skills — can explain technical decisions to both engineers and non-technical stakeholders

Nice to Have

• Experience in e-commerce platforms (catalog management, checkout flows, payment processing,
• order management)
• Experience in regulated industries (healthcare, fintech) with compliance requirements (HIPAA,
• PCI-DSS)
• Experience with multi-tenant or multi-channel architectures
• Familiarity with ERP/CRM integrations (HubSpot, Salesforce, NetSuite)
• Experience with queue systems, background job processing, and event-driven architecture
