About CONXAI CONXAI has built a   no-code, agentic AI platform  for the Architecture, Engineering and Construction (AEC) and physical industries, focused on  knowledge-automation . We automate high-stakes, knowledge-intensive workflows traditionally trapped in siloed data, fragmented tools and tacit (undocumented) human expertise. Our  multi-agent systems  perform complex reasoning in the physical world; and transform bespoke, service-heavy processes into scalable  Service-as-a-Software  automation. CONXAI is trusted by some of the leading AEC companies  in Europe, US, LATAM and Japan. Your Role As a Senior Backend Engineer , you will play a key role in designing and evolving the backend architecture that powers a complex B2B AI platform.
