  • Hands-on experience building large language model or agent evaluation systems, including autoraters, human-evaluation pipelines, benchmark design, or evaluation infrastructure.
  • Experience with multi-agent orchestration, retrieval-augmented generation, and tool-use or function-calling reliability.
  • Active research or publications in large language models, reasoning systems, model behavior, AI safety, or the societal impact of advanced AI systems.
  • Affiliation with a South Florida university and work under the supervision of a faculty member or professor, or recent graduate.

About the company

BrightStar.AI has pivoted to a new identity under RaiLTech.ai and is currently in stealth mode with no public site or product information available. The BrightStar.ai domain is for sale. Public details about the company’s product lines or technology have not been disclosed, so how its offerings work cannot be described. There is not enough information to compare with competitors, given the lack of public data. The apparent goal is to develop AI-related technology under the RaiLTech.ai banner while keeping development private until a public launch.
