Senior Software Engineer, Ecommerce Web Applications (US/Canada)

CSC Generation, through its Backcountry brand, is seeking a senior engineer to own the architecture, development, and reliability of ecommerce web applications. The role focuses on PHP-based storefront and back-office platforms, front-end experiences, data-layer optimization, system reliability, technical leadership, and AI-assisted development workflows.

Responsibilities:

• Drive architecture, hands-on development, testing, deployment, documentation, and production support across PHP web applications (a Symfony-based customer storefront and a Laravel back-office platform)
• Lead front-end direction with JavaScript (including jQuery) and CSS to deliver responsive, accessible, high-performing customer experiences
• Champion and evolve the team's AI-assisted development workflows: use AI tools daily, share techniques, and raise the bar for how effectively and responsibly the team uses them
• Own the data layer: design and optimize queries and schema interactions against relational databases (SQL Server and PostgreSQL) and supporting services
• Set and uphold engineering standards through code review, mentorship, testing practices, and clear technical documentation (design docs, runbooks, onboarding material)
• Improve reliability, observability, alerting, and incident response for mission-critical, customer-facing systems
• Identify opportunities to simplify legacy components, reduce technical debt, and deliver long-term efficiency gains
• Break large initiatives into deliverable chunks and clearly communicate status, roadblocks, and dependencies to engineering and product leadership
• Partner with Product, QA, and Engineering leadership to ship scalable, user-focused features that elevate business value

Requirements:

• Bachelor's or Master's degree in Computer Science or a related field, or equivalent professional experience
• 5+ years of professional software development experience with a strong ecommerce or high-traffic web application background
• Deep, hands-on expertise with PHP, including production experience with Symfony and/or Laravel
• Strong front-end skills with JavaScript and CSS, and a solid grasp of web fundamentals (HTTP, browser behavior, performance, accessibility)
• Strong understanding of relational databases and SQL, including query optimization and schema design
• Proven experience designing, building, and maintaining production systems with real end-to-end ownership
• Hands-on experience leveraging AI coding tools for development, and the ability to mentor others on using them effectively. This is an AI-development-driven team
• Experience with testing practices (unit/integration), Git workflows, and CI/CD
• Excellent communication and collaboration skills, and a track record of mentoring engineers and influencing technical direction
• Experience defining or scaling AI-assisted development workflows across a team (agents, prompts, tooling, guardrails)
• Python experience (Flask or data tooling) for supporting services
• Experience with Docker, Kubernetes, and cloud platforms (GCP or AWS)
• Familiarity with front-end build tools (Webpack / Laravel Mix), package managers (Composer, npm), and templating engines (Blade, Twig)
• Experience with event-driven or message-based architectures (e.g., RabbitMQ / AMQP)
• Experience improving observability and monitoring (structured logging, dashboards, tracing)
• Experience modernizing or incrementally refactoring legacy codebases
