  • Demonstrated experience with enterprise integration patterns (SOA, microservices, event-driven architecture).

  • Proficient in MuleSoft development including API-led architecture, DataWeave transformations, and AnyPoint MQ.

  • 3+ years of experience in relational and non-relational databases development and deployment on public cloud platforms.

  • Advanced API security, versioning, observability, and documentation practices.

  • Experience working with CI/CD automation, preferably GitLab and Terraform.

Preferred Qualifications

  • Experience with message queues (AnyPoint MQ), Apache Kafka, or Confluent Kafka.

  • Hands-on with AWS or Azure cloud services (AWS preferred).

  • Experience integrating with SAP, Salesforce, and other major ERP/cloud platforms.

  • Familiarity with OpenTelemetry and observability tools such as Splunk.

  • Excellent problem-solving skills and an ability to mentor peers with minimal supervision.

  • Strong communication and technical leadership skills.

Benefits

  • Comprehensive health benefits package (medical, dental, vision)
