This is not a traditional software engineering role; however, prior software engineering experience is essential. The ideal candidate understands how enterprise applications are built and integrated, allowing them to implement reliable, scalable, and maintainable solutions while contributing informed recommendations during technical solution discussions.

This is a highly collaborative, customer-facing position that works daily with Engineering, Operations, Sales, Customer Success, and customers throughout the integration lifecycle.

  • Data integrity
  
  
  • Idempotency
  
  
  • Error handling and recovery
  
  
  • Telemetry and observability
  
  
  • Retry and resiliency patterns
  
  
  
  


• Configure integrations between custom applications and commercial off-the-shelf (COTS) software platforms.


• Participate in customer technical discovery sessions to understand business processes and integration requirements.


• Recommend implementation approaches and identify technical risks while partnering with Evans technology leadership on solution direction.


• Troubleshoot production issues, participate in incident reviews, and continuously improve integration reliability.


• Create and maintain technical documentation for implemented integrations.

Requirements

Required

• Prior experience as a Software Engineer, Integration Engineer, or Solutions Engineer with hands‑on implementation responsibilities.


• Experience building enterprise API integrations.


• Strong understanding of REST APIs and API lifecycle concepts.

• Strong knowledge of JSON, XML, data mapping, and ETL processes.


• Experience integrating custom applications with commercial software platforms.


• Understanding of authentication and authorization protocols, including OAuth and OpenID Connect.


• Working knowledge of Amazon cloud services.


• Ability to communicate effectively with both technical and non-technical stakeholders.


• Comfortable leading technical discovery conversations and asking thoughtful questions before proposing solutions.

Preferred

• Experience with Boomi, MuleSoft, or other enterprise integration/iPaaS platforms.


• Familiarity with Enterprise Integration Patterns and API-first design principles.


• Experience with EDI integrations.
