Whether you are at HQ, in a retail store, or remote, you will be part of a team that thrives on energy, exploration, and connection. Reports to: Director of Engineering Location: Costa Rica (Remote) About the Role 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. What You'll Do • 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. Required Qualifications • 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. Preferred Qualifications • 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.
