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 research engineers at Zstate AI. AI labs come to us because they need to know where their models break in the real world. You will work with domain experts to design a benchmark, shape the tasks, write the scoring rubrics, and run models against it. Then you will find the failure modes, refine the benchmark, and turn the whole thing into a signal AI labs can trust and compare over time.
A day in the life
Design benchmark suites across diverse real-world domains, then build the evaluation framework and scoring methodology that makes the results defensible.
Build pipelines that run models at scale, score outputs, and generate performance breakdowns a lab can act on.
Read model outputs carefully to find where and how they fail, and use those failures to improve both the benchmark and the reward design.
