About the Job:

The eCommerce Systems Sr. Architect is a hands-on leader responsible for overseeing Pacsun’s Salesforce Commerce Cloud platform, mobile app, and the broader eCommerce technology ecosystem, including system integrations. This role works closely with business and IT teams to maximize the value of these technologies, ensuring optimal performance, scalability, and an exceptional customer experience.

Accountable from planning through launch and ongoing optimization, the Sr. Architect drives initiatives that enhance customer engagement, fuel sales growth, and streamline operations. This includes delivering innovative, efficient solutions that elevate the online customer journey and support Pacsun’s strategic business goals.

Success in this role requires strong technical expertise, strategic thinking, and close collaboration with cross-functional partners—including business leaders, IT, and external vendors—to ensure projects are delivered on time, within budget, and to the highest standards. The ideal candidate is forward-looking, results-oriented, and passionate about leveraging technology to accelerate Pacsun’s digital transformation.

A day in the life, what you’ll be doing:

• Enhance and support Pacsun’s e-commerce platform and mobile app – Design, implement and customize Salesforce Commerce Cloud (SFCC) solutions—including item catalogs, promotions, price books and product data—while ensuring that new features reflect Pacsun’s brand experience.
• End-to-end project execution – Manage e-commerce projects from concept through launch: gather requirements, translate them into technical use cases, oversee development and configuration, conduct rigorous QA, manage deployments and provide post-live support.
• Integrate with enterprise systems – Build and maintain integrations between SFCC and ERP, order-management, CRM, payment gateways and other third-party platforms. Manage API connections, map data fields and monitor data flows to ensure reliable commerce operations.
• Operational oversight and system management – Monitor system performance metrics and logs; manage instance states via Control Center (start/stop/restart, usage and audit logs); run regular health checks; and manage certificates and multi-factor authentication to uphold security.
• Troubleshooting and continuous improvement – Investigate and resolve system issues, analyze root causes, debug code and implement fixes. Identify performance gaps or process bottlenecks and develop technical solutions to enhance scalability and reliability.
• Customer-experience optimization – Use analytics, A/B testing and customer-behaviour insights to monitor the end-to-end customer journey (navigation, search, product pages, checkout and mobile app flows) and implement improvements that drive conversion and revenue.
• Release management and sprint execution – Plan and manage sprint releases and platform updates. Execute configuration changes, code deployments and data replication, perform unit and user-acceptance testing, and ensure stability and rapid response to business needs.
• Cross-functional collaboration – Work closely with merchandising, marketing, operations, IT, finance and customer-experience teams to translate business requirements into technical solutions. Manage competing priorities and communicate technical concepts to non-technical stakeholders.
• Mentorship and leadership – Provide hands-on technical leadership and mentorship to developers and analysts. Share expertise in SFCC architecture and best practices, review code and configurations, and encourage continuous skill development.
