Senior Backend Engineer (Python + AWS)

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.

2. Cloud Infrastructure & DevOps

• Architect and manage cloud-native applications on AWS or GCP.
• Deploy and operate services using ECS, EKS, Lambda, Cloud Run, GCP - GKE, and other cloud-native technologies.
  
• Implement and manage Infrastructure as Code (IaC) using Terraform or equivalent frameworks like Pulumi or CloudFormation.
• Build and optimize CI/CD pipelines for reliable and automated deployments.
• Experience with Apache Kafka for building event-driven, scalable, and distributed systems.
• Manage and troubleshoot containerized applications using Docker and Kubernetes, ensuring scalability, availability, and performance.

3. 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/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).
• Hands-on experience with Docker and Kubernetes for deploying and managing containerized applications.
• Experience with Apache Kafka for messaging, event-driven and distributed systems.
• Strong understanding of CI/CD pipelines and DevOps best practices.
• 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.
