The vacancy is well-structured with clear compensation and company information, but lacks specific KPIs and may misrepresent seniority.
Job description
Inworld is a product-oriented research lab of top AI researchers and engineers, developing best-in-class realtime multimodal models and the only realtime orchestration platform optimized for thousands of queries per second.

Responsibilities
### What Working Here Is Like
- We hand you unclear problems and expect you to make them clear.
- We value researchers who say "I don't know yet" and then design the experiment that finds out.
- We treat evaluation as a first-class research product, not a box to check before launch.
- Impact comes before publications though we support sharing work that moves the field forward.
- Your work should be visible.
- Flat structure, fast iterations, minimal process theater.
- We believe in the power of in-person collaboration to solve the hardest problems and foster a strong team culture.
Requirements
### Experience We Find Useful
- Foundation models: training, new architectures, RL, reward modeling, scaling.
- Evaluation: benchmarks, eval loops, quality measurement, LLM-as-judge, failure analysis.
- Frontier topics: multimodal models, agents, tool use, test-time compute, world models.
- Published research at ICML, ICLR, NeurIPS, EMNLP, ACL, or AAAI.
- PhD in ML/NLP — or equivalent practical experience you can point to.
- Public work: non-trivial AI side projects, interdisciplinary experiments, open-source contributions.
- Full-stack research ownership: you frame the question, run the experiments, write the paper, ship the result.
Conditions
### What We Offer
- Relocation assistance.
- Base salary range for this full-time position is $270,000 - $500,000+ bonus + equity + benefits.
