Senior Backend Engineer Klugsys PropTech

Key Responsibilities:

· Design, build, and maintain microservices using Python (FastAPI) and Docker.

· Develop and expose secure APIs (REST, WebSocket) for mobile, agent, and web apps.

· Implement features for user onboarding, search, recommendations, notifications, AI-based workflows, and analytics.

· Integrate external APIs (e.g. OpenAI, OpenSearch, External APIs, LiveKit and many more as a part of the project).

· Design and manage scalable infrastructure on AWS ECS (Fargate/EC2), Lambda.

· Handle secure multi-tenant environments with IAM roles, tagging, and isolation.

· Implement secure secrets management, monitoring (CloudWatch, X-Ray), and logging pipelines.

· Enforce secure API access using Cognito, JWT, and API Gateway Authorizers.

· Manage event-driven architecture, optimize cost, performance, and observability across services.

· Audit and monitor cloud usage, IAM policies, encryption standards, and compliance setups.

· Enable real-time integration with Generative AI APIs and LLM orchestration layers.

· Orchestrate AI-powered features including chat, recommendations, smart forms, and summarizations.

· Collaborate on RAG pipelines: Integrate document stores (e.g., Pinecone), embeddings, and search layers.

· Design LLM-based microservices for tasks like semantic search, summarization, Q&A, and intent recognition.

· Work with the AI/ML team to abstract prompt templates, vector search APIs, and long-context data retrieval.

· Build fault-tolerant systems with autoscaling, secrets management, and role-based access control (RBAC).

· Monitor system health using CloudWatch, Open Telemetry, X-Ray, Prometheus, and alarms.

· Streamline CI/CD for backend and infrastructure updates.

· Maintain modularity to support future portability to GCP or Azure if needed.

· Follow best practices in stateless services, decoupled APIs, and open standards (e.g., CloudEvents).

· Explore options like Kubernetes, Crossplane, or Pulumi for future polycloud strategy.

Job Summary: We’re hiring a Senior Backend Engineer who brings deep expertise in backend engineering, cloud-native architecture, and a product-first mindset to deliver a next-generation AI-powered real estate platform. You’ll lead core system design and implementation — from microservices and CI/CD pipelines to event-based data processing and AI/LLM integrations.

This role also demands a strong grasp of LLM-based systems, especially Retrieval-Augmented Generation (RAG), multi-modal input handling, and cloud-agnostic strategies that ensure our platform remains scalable and portable across cloud environments.

You will collaborate with AI engineers, data scientists, DevOps, and frontend teams to translate vision into a production-grade system. This is a key role in our engineering team powering a next-gen AI-powered real estate app and web platform in the UAE market.
