← All rolesFounding Research EngineerFounding Team Full-time Gurugram, India Apply for this role → Or write to careers@zstate.aiAbout ZstateAs 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.

Responsibilities

• 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.
• Develop expert grading rubrics, LLM-as-a-Judge workflows, and evaluation methodologies for post-training.
• Build internal tools and workflows that make benchmark creation, expert authoring, and evaluation faster and cleaner.
• Build the evaluation infrastructure that shapes how frontier AI models are tested and improved.
• Work directly with the founders and help shape both the product and the company from day one.Solve challenging engineering problems that influence how state-of-the-art AI models are evaluated.
• Take ownership of meaningful technical work with rapid learning, visible impact, and growth opportunities as we scale.If structured thinking, messy problems, and building the evals that hold AI systems to a higher bar sounds interesting, send your resume and a short note on why this role interests you to vijay@zstate.ai or careers@zstate.ai.
