  • Implement and maintain CI/CD pipelines, automated testing, and DevOps practices
  • Collaborate with cross-functional teams including Salesforce developers, architects, and product owners
  • Provide production support and lead root cause analysis for complex issues across distributed systems

Salesforce (Preferred)
  • Experience integrating .NET applications with Salesforce via REST/SOAP APIs, Platform Events, or middleware (e.g., Mulesoft)
  • Familiarity with Salesforce data model, security model, and governor limits as they relate to external integrations
  • Exposure to Apex, Flows, and Lightning components to effectively collaborate with Salesforce engineering teams
  • Experience designing hybrid architectures (.NET services + Salesforce platform) for enterprise workflows
  • Understanding of data synchronization patterns, error handling, and retry strategies across platforms
