About the job

Inworld is a research lab building top-ranked real-time voice models used in large consumer-facing AI applications. We focus on 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 who learn fast, thrive in ambiguity, and can demonstrate their built projects, broken systems, and understanding. We value impact and shipping results, with a bias for action and first-principles thinking.

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.
  • Collaborate daily with US-based leadership and engineering teams.

Requirements

  • Experience with foundation models: training, new architectures, RL, reward modeling, scaling.
  • Experience with evaluation: benchmarks, eval loops, quality measurement, LLM-as-judge, failure analysis.
  • Familiarity with frontier AI topics: multimodal models, agents, tool use, test-time compute, world models.
  • Published research at top-tier conferences (ICML, ICLR, NeurIPS, EMNLP, ACL, or AAAI).
  • PhD in ML/NLP or equivalent practical experience.
  • Demonstrated public work: non-trivial AI side projects, interdisciplinary experiments, open-source contributions.
  • Ability to take full-stack research ownership from question framing to shipping results.
  • Professional fluency in English (written and spoken).

Benefits

  • Full U.S. visa and relocation support may be available for candidates interested in relocating to the San Francisco Bay Area.
