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
Location: Coimbatore / Chennai — Hybrid Notice Period: Immediate to 30 days preferred
