## Description

* Own sending domain management for thousands of dealerships: store-specific and shared sending domains, DNS records (SPF, DKIM, DMARC), link and SSL branding, and a normalized source of truth for domain configuration.
 * Protect deliverability and sender reputation. Diagnose DMARC failures, hard and soft bounces, and mailbox-provider blocks (Xfinity, iCloud, and others), and report on blocked and bounced mail by store.
 * Architect and scale the Email Blast platform: batching and send queues for high-volume and shared domains, scheduling within store hours, audience accuracy, partitioned tables, and blast metrics for reporting.
 * Build and maintain the services behind transactional, inbound, and price change emails.
 * Integrate with and manage email service providers (SendGrid, Mandrill, Mailchimp): API keys and subusers, event webhooks, routing traffic between providers, and staying inside provider limits and compliance policies.
 * Own APIs and event-driven pipelines (Kafka) that carry that data back to the CRM.
 * Navigate email compliance and abuse prevention: CAN-SPAM, Canada's CASL, FTC requirements, List-Unsubscribe headers, opt-out handling, and blocking malicious links in inbound and outbound mail.
 * Design and develop customer and admin facing Angular UI for customer interactions and store management.
 * Build testability into communication systems: simulated providers, webhook forwarding for dynamic environments, automated tests for unsubscribe and send flows, and load and allocator simulators.
 * Assist in identifying and resolving issues. Research escalations from support teams, dealership email problems, and bug reports. Perform root cause analysis and address identified issues.
 * Keep services healthy and current: framework and library upgrades, dependency and security remediation, query tuning, retry and dead-letter handling, APM monitoring, and alert tuning.
 * Participate in story refinement, release planning, and code review. Deploy your own validated code to production.
