About the Role

We are looking for a highly skilled Senior Backend Engineer to design, develop, and scale AI-powered applications and backend platforms. The ideal candidate will have strong expertise in backend engineering, cloud-native architectures, Retrieval-Augmented Generation (RAG) systems, Agentic AI frameworks, and production-grade LLM deployment. This role requires hands-on experience in building scalable AI solutions, optimizing cloud infrastructure, and ensuring reliability, observability, and security in production environments. 1.

Backend

Engineering & Platform Development

● Design, develop,



and maintain scalable backend services using Python, FastAPI, and asynchronous microservices architectures.

● Build and optimize data-intensive applications using PostgreSQL, Redis, MongoDB or equivalent technologies at production scale.

● Develop high-performance APIs and distributed systems to support AI-driven applications. 2.

Cloud

Infrastructure & DevOps

● Architect and manage cloud-native applications on AWS or GCP.

● Deploy and operate services using ECS, Lambda, Cloud Run, and other cloud-native technologies.

● Implement and manage Infrastructure as Code (IaC) using Terraform or equivalent frameworks like Pulumi, Cloudformation.

● Build and optimize CI/CD pipelines for reliable and automated deployments.

- Retrieval-Augmented Generation (RAG) & Agentic AI Systems

● Design and implement production-grade RAG pipelines.

● Build hybrid retrieval systems using BM25, pgvector, vector databases, and semantic search techniques.

● Optimize retrieval accuracy, latency, and scalability for enterprise use cases.

● Build agentic workflows (LangGraph or similar) with tool calling, multi-step orchestration, and production guardrails like fallback routing and human-in-the-loop controls.

- Monitoring and Observability

● Instrument backend services end-to-end with metrics,



distributed tracing, and structured logging using OpenTelemetry

● Hands-on with some observability stacks — Prometheus + Grafana, Datadog/Current Relic, and centralized logging (ELK/Loki)

● Build actionable dashboards and alerting to detect latency, errors, and resource bottlenecks before customer impact

● Experience with LLM/AI system observability — token usage, latency, and quality tracing (Langfuse, LangSmith, Arize) Requirements

● 4+ years of experience in backend development.

● B.E.B.TechB.S. Candidates' entries with significant prior experience in the fields above will be considered.

● Strong experience in Python development and FastAPI.

● Hands-on experience with asynchronous microservices architectures.

● Expertise in PostgreSQL, Mongodb, Redis, and distributed backend systems.

● Experience with AWS or GCP cloud platforms and Infrastructure as Code (Terraform, Cloudformation or equivalent).

● Strong understanding of CI/CD pipelines and DevOps best practices.

● Proven experience building and deploying RAG systems in production environments.

● Experience with LangGraph, tool calling, and agent-based AI architectures.

● Experience with development using AI coding agents like claude code, cursor, codex or equivalent.

● Guardrails in production: model fallback routing, prompt-injection defense, token cost budgets.

● Demonstrated ownership mindset with the ability to drive projects and deliver high-quality solutions.

● Experience in mentoring team members, conducting code reviews, and sharing best practices.
