A highly skilled and motivated Senior Full-Stack Engineer to own the technical operation and evolution of client’s website, Shopify e-commerce platform and the back-end services that connect it to web and mobile experiences, ticketing partners, customer accounts and MarTech. This is the hands-on Shopify platform owner under the Web Application Architect’s technical direction, with direct responsibility for purchase-path reliability and abuse protection.

• Build and maintain Shopify integrations, webhooks and APIs for embedded commerce, ticketing handoffs, customer identity and downstream events; design retries, reconciliation and failure recovery.
• Own technical bot and abuse prevention across the purchase path. Monitor suspicious traffic and checkout behaviour; coordinate Shopify-native controls where eligible and client-controlled CDN, WAF, API rate-limit and challenge controls with Security and platform teams.
• Test controls against legitimate customer conversion, especially high-demand releases and mobile WebViews; maintain incident playbooks and work with Shopify and ticketing vendors during attacks.
• Build and support the current Python/Django application layer and AWS-hosted services, with secure deployment, observability and production incident response.
• Document platform configuration, integration contracts, access, change procedures and operational runbooks.
• Implement and maintain privacy controls across customer accounts, APIs, and commerce data flows; resolve defects and coordinate changes with the MarTech engineer, Privacy, and Legal.

Required Qualifications

• 5+ years engineering and operating production e-commerce platforms, including substantial hands-on Shopify experience with checkout, apps or extensions, APIs, webhooks and admin configuration.
• Experience protecting high-demand commerce journeys from bots, credential abuse or automated checkout, using platform controls, edge security, telemetry and incident response.
• Strong back-end development experience with Python/Django or comparable API services, plus relational databases and secure customer-data handling.
• Hands-on AWS, CI/CD, infrastructure as code, monitoring and troubleshooting of live commerce incidents.
• Ability to work with Commerce Operations, Security, vendors and product teams to balance abuse prevention with successful legitimate purchases.
