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

Backcountry is looking for a senior engineer to own the architecture, development, and reliability of the web applications powering our ecommerce business - the customer-facing storefront, the back-office operations platform, and the supporting services that connect them. As Senior Software Engineer, Ecommerce Web Applications, you will work primarily in PHP applications (a Symfony-based storefront and a Laravel back-office platform), shape the front-end experience with JavaScript and CSS, and drive technical direction that the rest of the team builds on.

Within your first 6-12 months you will have delivered measurable improvements to system reliability and performance, reduced technical debt in legacy components, established patterns that lift the whole team’s delivery velocity, and become a trusted technical leader others turn to. AI coding tools are core to how this team works - you will use AI-assisted development daily, raise the bar for how the team leverages it, and help define the workflows, patterns, and guardrails that make AI-augmented engineering effective and safe.

This is a lean team. You will own a lot, move fast, and make decisions with full end-to-end responsibility., * 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).

• 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., The people who do best here are builders. They take ownership, move fast, and want to see the direct impact of their work.
• Cross-Functional Impact: Your work on the storefront and operations platform directly affects how customers shop and how internal teams operate - touching product, QA, and engineering leadership daily.
• AI-First Skill Building: This is an AI-development-driven team. You will use modern AI coding tools every day and help define the workflows, patterns, and guardrails that make the whole team more effective.
• End-to-End Ownership: Own architecture decisions, technical direction, and delivery for customer-facing systems.
