We believe that the next generation of AI progress won't come from just bigger models, but from more rigorous, long-horizon simulation and programmatic verification.\nSimLab allows researchers to spin up realistic environments, run agents through complex tasks, and surface failure modes under real-world conditions. We then close the loop by generating targeted synthetic data to retrain models, delivering measurable quality lift on the metrics that actually matter.\nAbout the Role\nWe are looking for a talented Member of Technical Staff (MTS - Engineering) with expertise in React and NextJs (JavaScript frameworks) for frontend development and backend development in Python and Fast API.
