Senior Software Engineer in Markham

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
• 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, Git Hub 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 (My SQL/Postgre SQL, 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 (Hub Spot, Salesforce, Net Suite)
• Experience with queue systems, background job processing, and event‑driven architecture
• Why join us? (Brace yourself…)
• We offer competitive compensation
• Extended Health and Dental Benefits Plan (100% Employer‑paid Premiums on eligible benefits)
• Continuous Learning Assistance Program reimbursing up to $1,500 per calendar year
• Group RRSP (Non‑match)
• 15 Vacation Days to start and scale to 20 Vacation Days.
• Paid Religious Holidays and Volunteer Days
• Flexibility to help you balance work and life
• Corporate Good Life Fitness Membership Discount
• Supportive leadership team and Culture Committee that works to maintain a positive culture
• Fully stocked snacks, team BBQs and other company paid meals (we love to eat!)
