AI Lead (Backend Systems & Architecture)

This is not a feature-delivery role. This is an architecture, ownership, and AI systems leadership role. At Techjays, we build production-grade AI platforms for global clients. We are looking for an AI Lead with strong backend engineering expertise - someone who can design, scale, and take complete ownership of intelligent systems end-to-end.

What You'll Do :

- Architect and scale backend systems powering AI-driven applications.

- Design and implement AI workflows such as RAG pipelines, agents, and LLM integrations.

- Own systems end-to-end : architecture, development, deployment, and scaling.

- Build reliable, high-performance distributed systems.

- Integrate and optimize LLMs (Claude, GPT, etc.) for real-world use cases.

- Lead backend and AI initiatives with strong technical ownership.

- Ensure performance, scalability, observability, and cost efficiency.

- Mentor engineers and raise the technical bar across teams.

- Collaborate with product and AI teams to build AI-native solutions.

What We're Looking For :

- Proven experience in architecting and scaling backend systems end-to-end.

- Strong expertise in Python (Django / Flask / FastAPI).

- Deep understanding of distributed systems and system design.

- Hands-on experience with AWS or GCP in production environments.

- Solid experience working with LLMs (Claude, GPT, etc.).

- Strong knowledge of Retrieval-Augmented Generation (RAG) and Vector databases (Pinecone, FAISS, Weaviate, etc.).

- Experience in building and managing microservices architectures.

- Ability to lead teams, mentor engineers, and drive technical excellence.

- Strong problem-solving skills with an ownership mindset.

Nice to Have :

- Experience building AI agents or autonomous systems.

- Familiarity with real-time data systems or streaming (Kafka, etc.).

- Understanding of MLOps and AI system lifecycle.

- Experience optimizing AI systems for latency, cost, and scalability.

Who You Are :

- You think in systems, not just features.

- You take full ownership of what you build.

- You are comfortable in fast-moving, ambiguous environments.

- You stay updated with the latest advancements in AI and backend technologies.

This role is ideal for someone who wants to lead, build, and scale AI-powered backend systems in production while driving real-world impact.

Skills :

Artificial Intelligence (AI), Claude AI, AI Agents, Large Language Models (LLM), Python, Django, Flask, Prompt engineering, CI/CD, RESTful APIs and FastAPI.
