We’re hiring a Founding Senior BackEnd Engineer — someone who wants to design, build and own the entire backend and systems architecture.



This is not a maintenance role. It’s a founding role, with high phantom -share compensation, where you will shape the core platform that powers real -time AI assistants used by millions of visitors across malls, airports, stadiums and resorts.



You'll own the backend, APIs, microservices, data flows, real -time orchestration, and ML integrations end -to -end—ensuring performance, security, and scalability as we expand across international portfolios.



This role sits at the intersection of AI, product engineering, infrastructure, data architecture, and ML operations.





- Backend & microservices end -to -end.

- Build scalable APIs, workers, queues, and real -time systems on GCP + Cloud Run + Cloud SQL.

- Implement integrations with CRMs, CMSs, booking systems, loyalty platforms, and external APIs.

- Develop backend support for AI agents: retrieval APIs, embeddings, vector DB, inference services.

- Build and maintain event pipelines for analytics, ML, and product insights.

- Ensure system security, observability, monitoring, logging, and CI/CD best practices.





- Collaborate with Product & AI teams to define technical architecture and implement new features quickly.

- Own migrations, deployments, environments, CI/CD, and platform reliability.
