About Zstate
As AI models become increasingly capable, the industry needs better ways to measure reasoning, reliability, and real-world performance.
Zstate AI is building the evaluation and post-training infrastructure powering the next generation of AI systems. We create expert-driven benchmarks, reward signals, RL environments, and high-quality datasets that help frontier AI models become more capable, reliable, and trustworthy across diverse real-world domains.
Zstate AI is led by a founding team from IITs, IIMs, and DCE, bringing together deep technical and strategic expertise to build category-defining AI infrastructure. We are backed by Giraffe Studios, a venture studio focused on deep-tech startups founded by Himanshu Aggarwal (Co-founder & CEO, Aspiring Minds) and Mohit Tandon (Co-founder, Delhivery).
As one of our earliest hires,
you'll work directly with the founders to solve challenging engineering problems and help shape both the product and the company from day one.
What this role looks like
You are one of the first engineers at Zstate AI. Our enterprise clients hand us real workflows that take too much expert time, and your job is to turn those workflows into agents that work. You will design and build multi-step agents that use tools, retrieve context, hold state, and complete the work end to end, from an early prototype to a production deployment the client actually relies on.
A day in the life
Spend your mornings sketching agent architectures on a whiteboard or in a notebook: subagents, routing, handoffs, planning, and state management for long tasks.
Build those agents with LLMs, tool use, retrieval, and memory in LangChain, LangGraph, or whatever framework fits the problem best.
Write evaluation frameworks that let you iterate on prompts and architecture using LLM-as-judge and deterministic evaluators, so you can
