About the project
TROP is an advanced situational awareness and operational coordination platform developed by Defencebay. By combining real-time mapping, secure communications, drone integration, AI-ready workflows and resilient Mesh LoRa networking, TROP helps teams maintain a shared operational picture when standard infrastructure is limited or unavailable. We are building next-generation technology for public safety, emergency response, critical infrastructure protection and defense operations.
Defencebay is a sub-brand of Devopsbay, focused on building advanced technologies for public safety, defense, and crisis communication systems. The recruitment process for this role is conducted under the Defencebay brand, as part of our dedicated product team working on the TROP platform. While being part of the broader Devopsbay organization, Defencebay operates as an independent product unit responsible for developing mission-critical solutions in the area of situational awareness and resilient communications

With that wide knowledge, we can make your company better, from cost-saving infrastructure things to real new solutions that can make your car drive automatically.
(yes, we did that kind of project).
