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.
Responsibilities
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.
-
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.
-
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.
- Instrument backend services end-to-end with metrics, distributed tracing, and structured logging using OpenTelemetry
-
Hands-on with some observability stacks — Prometheus + Grafana, Datadog/New 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.Tech\B.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.
