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

Senior AI Engineer — Ruby on Rails

Techjays · Coimbatore / Chennai · Hybrid · Immediate – 30 Days Notice

About Techjays

We're the AI Reimagination Company — and that's not a tagline we put on a deck. It's what we actually do.

Techjays helps global enterprises rebuild the way they operate using AI at the core: not as a pilot, not as a feature, but as a foundational layer across products, workflows, and infrastructure. We're an Anthropic partner, which means our engineers get early access to frontier models and tools before they hit the market.

Our team includes engineers and leaders from Google, Akamai, NetApp, ADP, Cognizant Consulting, and Capgemini. We run like a high-agency startup, but we build production systems that real enterprise clients depend on.

Every project is greenfield. Every line of code you write ships.

What This Role Actually Is

This isn't a "keep the monolith alive" job.

You'll be designing and building new AI-powered features, integrating LLM APIs into production Rails applications, and using Claude Code as a core part of your daily workflow — not as an experiment. You'll work directly with US-based enterprise clients alongside Product Managers, AI Business Consultants, and Delivery Excellence Managers.

Your architecture decisions will have visible business impact.

What You'll Own

• Design, build, and maintain production-grade Ruby on Rails applications for US enterprise clients — from architecture to deployment
• Integrate LLM APIs (Claude, GPT-4, Gemini) into the Rails stack, building AI-powered features that drive real business outcomes
• Use Claude Code daily as your AI development partner — for generation, debugging, documentation, and velocity
• Build responsive, performant React front-ends from wireframes and design specs
• Own RESTful and GraphQL API design for client applications and third-party integrations
• Drive database design and optimisation — schema, queries, indexing, and migrations on PostgreSQL/MySQL
• Lead code reviews and raise the technical bar through constructive feedback
• Document architecture decisions, API contracts, and implementation patterns

Must-Haves

• 6+ years of deep, production-grade Ruby on Rails experience — advanced framework patterns, background jobs (Sidekiq/Redis), design patterns, best practices
• Hands-on experience with Claude Code (Anthropic) for AI-assisted development — this is central to how we build
• Strong React skills — hooks, component architecture, state management, wireframe to production
• Expert-level PostgreSQL/MySQL — schema design, query optimisation, indexing, performance tuning
• Proven experience designing RESTful and GraphQL APIs at scale
• Experience integrating third-party LLM APIs (OpenAI, Anthropic, Google Gemini) into production Rails apps
• Strong software architecture fundamentals — MVC, service objects, design patterns, testability
• Deep comfort with Git, Gitflow, and PR-based collaboration workflows

Good to Have

• Python for scripting, automation, or backend service integration alongside Rails
• AWS familiarity — EC2, S3, RDS, Lambda — for deployment and infrastructure
• MongoDB or NoSQL in polyglot persistence architectures
• Vector databases (Pinecone, pgvector, Weaviate) for LLM application development
• LangChain, LangGraph, or similar orchestration frameworks for AI agents
• SaaS multi-tenancy patterns and high-traffic web application experience
• Open source contributions or a strong public GitHub profile

Why Join Techjays

• Claude Code is standard practice here, not a side experiment — you'll use it every day to ship faster and smarter
• Anthropic partner access — early visibility into frontier AI tools and capabilities before the market sees them
• Greenfield only — you'll design architecture, not inherit technical debt
• Global client exposure — your engineering decisions translate directly to measurable business outcomes for US enterprise clients
• Team pedigree — you'll learn alongside engineers who've shipped at real scale at Google, Akamai, and NetApp
• AI is the product here, not a feature. You'll spend your career at the intersection of software engineering and AI systems

What We're Looking For Beyond the Resume

• Builder mindset — you think in systems, not tickets
• Ownership — you take features from idea to production
• Structured thinking in ambiguous, fast-moving environments
• Clear communicator, collaborative team player

What We Offer

• Competitive compensation
• Hybrid work — Coimbatore office or remote flexibility
• Paid holidays and flexible time off
• Medical insurance for self and family (up to ₹4 Lakhs per person)
• Opportunity to work on production-grade AI systems for global clients
• A culture built on clarity, integrity, and continuous growth
