Looking for Python Lead with MongoDB

About Techjays

At Techjays, we build production-grade AI platforms for global clients. We operate at the intersection of backend engineering, distributed systems, and applied AI — delivering secure, scalable, and enterprise-ready intelligent systems. Our team has built and scaled products at Google, Akamai, NetApp, ADP, Cognizant, and Capgemini.

About the Role

This is not a feature-delivery role. We are looking for an AI Lead who can architect, own, and scale intelligent backend systems end-to-end. You will drive both technical direction and execution — working across LLM integrations, RAG pipelines, agentic AI workflows, and cloud-native backend systems for global clients.

What You'll Do

• Architect and scale backend systems powering AI-driven applications
• Design and implement RAG pipelines, AI agents, and LLM integrations
• Own systems end-to-end — from architecture to deployment and scaling
• Integrate and optimize LLMs (Claude, GPT, Gemini) for real-world production use cases
• Build high-performance distributed systems with observability and cost efficiency
• Lead backend and AI initiatives with strong technical ownership
• Mentor engineers and raise the technical bar across teams
• Collaborate with product and AI teams to deliver AI-native solutions

What We're Looking For

• 6–10 years of strong backend engineering experience
• Hands-on expertise in Python (FastAPI / Django / Flask)
• Deep understanding of Generative AI and LLM-based systems
• Strong experience with RAG pipelines and Vector Databases (Pinecone, FAISS, ChromaDB, Weaviate)
• Solid knowledge of Agentic AI — building autonomous agents and multi-agent workflows
• Proficiency in AWS or GCP in production environments
• Experience with distributed systems, microservices, and system design
• Strong grasp of Data Structures, Algorithms, and Design Patterns
• Familiarity with WebSockets, Git, Linux/Unix, and CI/CD

Nice to Have

• Experience with Anthropic Claude API and Claude Code
• Familiarity with real-time data systems or streaming (Kafka, etc.)
• 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 navigating fast-moving, ambiguous environments
• You stay updated with the latest in Generative AI and backend technologies
• Strong communicator who can collaborate across teams and global clients

What We Offer

• Competitive compensation (Best in Industry)
• Work on production-grade AI systems used by global clients
• Exposure to cutting-edge AI tools and frameworks
• A culture that values clarity, integrity, and continuous growth

Roles and Responsibilities:

• Own development, design, scaling, and maintenance of application and messaging engines that power the central platform of Capillary's Cloud CRM product.

• Work on the development of AI and data science products for various use cases. Implement PoCs in Python, and Spark-Scala and productize the implementations.

• Contribute to overall design and roadmap.

• Mentor Junior team members.

Required Skills:

• Innovative and self-motivated with a passion to develop complex and scalable applications.

• 3+years of experience in software development with a strong focus on algorithms and data structures.

• Strong coding and design skills with prior experience in developing scalable & high-availability applications. Expertise in using Core Java/J2EE or Node.js

• Work experience with Relational databases and Non-Relational is required (Primarily MySQL, MongoDB, and Redis)

• Familiarity with big data platforms (like Spark-Scala) is an added plus.

• Strong Analytical and Problem Solving Skills.

• BTech from IIT or BE in computer science from a top REC/NIT.

Job Perks

• Competitive Salary as per market standards

• Flexible working hours

• Chance to work with a world class engineering team.
