  • Implement military and industry-standard protocols (Cursor-on-Target, Link 16, TAK/ATAK, VMF) and ensure interoperability compliance
  • Gather integration requirements from customers and partners; define interface control documents and translate operational needs into specifications
  • Build and execute integration test plans including simulation and hardware-in-the-loop testing before field deployment
  • Support customer demonstrations, pilots, and field deployments with troubleshooting across the full technical stack

What they're looking for

  • Systems integration and enterprise integration patterns
  • REST, SOAP, and pub/sub messaging APIs
  • Data serialization (JSON, XML, Protobuf)
  • Python, Kotlin, C++, or C# programming
  • Military/industry standards (Cursor-on-Target, Link 16, TAK/ATAK)
