Company Description
Moleculyst Ventures Private Limited is a deep-tech artificial intelligence research startup focused on building more reliable, autonomous, and scientifically capable AI systems.
Our current research focuses on hallucination detection in large language models, mechanistic understanding of model behavior, uncertainty and reliability estimation, and the development of automated AI research pipelines.
We are building systems that can assist with the full research cycle: reading technical literature, identifying open questions, generating hypotheses, designing experiments, executing computational studies, analyzing results, and retaining helpful knowledge across iterations.
A central goal of our work is to understand when AI systems possess relevant internal knowledge but still produce incorrect or fabricated outputs, and to develop methods for detecting and reducing such failures.
Moleculyst is also developing infrastructure for self-improving research agents, including scientific memory systems, experiment orchestration, model evaluation,



and tools for reproducible AI research.
Our broader objective is to create AI systems that can function as reliable scientific collaborators rather than simple language interfaces—systems capable of reasoning, experimentation, self-evaluation, and increasingly autonomous discovery.
Role Description — Natural Language Processing / AI Research Engineer
As a Natural Language Processing / AI Research Engineer at Moleculyst, you will work on research involving large language models, hallucination detection, model reliability, scientific reasoning, and automated AI research systems.
This role goes beyond conventional NLP tasks such as text classification or basic information extraction. You will study how language models represent and retrieve knowledge, why they hallucinate, and how internal model signals can be used to predict whether an output is reliable.
You will also contribute to the development of AI research agen
