About Techjays :

We're the AI Reimagination Company. Techjays helps global enterprises rebuild the way they operate using AI at the core. We're an Anthropic partner, which means our engineers get early access to frontier models and tools. 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.

- Use Claude Code daily as your AI development partner.

- Build responsive, performant React front-ends.

- Own RESTful and GraphQL API design.

- Drive database design and optimisation on PostgreSQL/MySQL.

- Lead code reviews and document architecture decisions.

Must-Haves :

- 6+ years of deep, production-grade Ruby on Rails experience.

- Hands-on experience with Claude Code (Anthropic).

- Strong React skills.

- Expert-level PostgreSQL/MySQL.

What We Offer :
