• Develop the Backend: Design, build, and maintain the entire backend on the Supabase platform, writing all core business logic in Supabase Edge Functions (Deno/TypeScript).
• Manage Event Systems: Maintain and enhance the real-time PMP event capture system utilizing AWS EventBridge, Lambda, and DynamoDB.

• Expert-level knowledge of AWS, specifically with programmatic interaction using the AWS SDK. You must have deep experience with IAM, STS (cross-account role assumption), and CloudFormation.
• Serverless expertise, with proven experience building applications using Supabase Edge Functions (Deno/TypeScript) or similar platforms like AWS Lambda.
• Integration experience, demonstrating the ability to integrate multiple third-party REST APIs, handle complex authentication (OAuth 2.0, API keys), and process webhooks reliably.
• Security-first mindset, with a profound understanding of cloud security principles, especially within a multi-tenant SaaS context.

Bonus Points

• Advanced AWS Experience: Direct, hands-on experience with the AWS Marketplace Catalog API, AWS License Manager, or AWS Organizations.
• AI Tooling Advocate: Demonstrable enthusiasm for learning and integrating AI tools into your daily engineering workflow to improve productivity and backend performance.
• B2B Commerce: Familiarity with cXML or other B2B e-commerce protocols.
