  • Drive prioritization decisions and trade-offs through working with product partners
  • Automate and simplify all aspects of software delivery and development
  • Introduce new technologies and architectures aligning to enterprise guidelines by conducting POCs
  • Provide coding and design guidance to junior team members
  • Own complex problems having dependency across services and facilitate cross-functional team interactions to drive resolution
  • Define, design, and develop procedures and solutions at a service level to meet the business requirements/enhancements
  • Participate and contribute to team's agile process and decisions. Understand and contribute to Prioritization. Drive prioritization decisions and trade-offs in working with product partners

  • Excellent programming skills (OOP, SOLID, 12-factor) - Java preferred
  • Experience with distributed systems architecture and implementation
  • Familiarity with secure coding standards (e.g., OWASP, CWE, SEI CERT) and vulnerability management
  • Experience with broker technologies Kafka/NATS is a plus
  • Experience in Continuous Integration (CI) and Delivery (CD) concepts, and capabilities to support automation, pipelines, virtualization, and containerization
  • Infrastructure as code and cloud-first software development knowledge experience preferred
  • Skills in test-driven and behavior-driven development (TDD and BDD) to build just enough code and collaborate on the desired functionality
  • Understanding of use cases for advanced design patterns (e.g., service-to-worker, MVC, API gateway, intercepting filter, dependency injection, lazy loading, all from the Gang of Four) to implement efficient code
  • Skills to elaborate and estimate non-functional requirements, including security (e.g., data protection, authentication, authorization), regulatory, and performance (SLAs, throughput, transactions per second)
  • Able to perform debugging and troubleshooting to analyze core, heap, thread dumps, and remove coding errors
