About the job

Inworld is a research lab building top-ranked real-time voice models used in large consumer-facing AI applications. Our work spans research and development of state-of-the-art models, optimizing real-time inference, and creating best-in-class APIs and products. We are looking for strong individuals from varied backgrounds who learn fast, thrive in ambiguity, and can demonstrate their built, broken, and understood work. We believe in the power of in-person collaboration to solve the hardest problems and foster a strong team culture.

Responsibilities

  • Frame research questions, run experiments, write papers, and ship results.
  • Develop and train foundation models, including new architectures, RL, reward modeling, and scaling.
  • Implement and refine evaluation methodologies, including benchmarks, eval loops, quality measurement, LLM-as-judge, and failure analysis.
  • Explore and implement frontier AI topics such as multimodal models, agents, tool use, test-time compute, and world models.
  • Contribute to published research at top-tier conferences like ICML, ICLR, NeurIPS, EMNLP, ACL, or AAAI.
  • Engage in full-stack research ownership from problem definition to solution delivery.

Requirements
