Role As Atla’s Chief Scientist, you’ll lead frontier research into training large language models, and advance the state of the art in AI safety research. As part of your role, you will: Steer LLMs to become strong evaluators aligned with human preferences using advanced post-training techniques. Lead and empower a world-class team of researchers and engineers, setting a high bar of excellence that propels Atla forward. Define and execute an ambitious research agenda that advances Atla's position as a leader in language model evaluation. Develop comprehensive evaluation frameworks, including tooling, datasets and metrics for rigorous assessment of alignment and safety risks. Contribute significant findings to leading AI safety conferences and journals.
Please note that this role is in-person (we can sponsor visas and offer international relocation support as a UK AI Futures partner!)
Qualifications Proven AI research leadership: Track record of 5+ years in pioneering AI research, with significant contributions to the field of LLMs, evidenced by publications in top-tier conferences and journals. Proven experience in defining and executing research agendas, demonstrating the ability to guide and align a team toward achieving ambitious research goals. Demonstrated success leading teams of researchers. Deep expertise in training and evaluating language models across GPUs, preferably in PyTorch. Experience at elite AI research lab (OpenAI, DeepMind, Meta, Anthropic, Cohere, etc.).
Nice to have Experience at a fast growing startup. Strong software, ML engineering expertise with a focus on building robust, scalable system.
About you You'll work by and thrive through our core principles: Own the Outcome Create real value: Every action should deliver tangible, meaningful value for the people who use what we build. Drive to completion: Do the second 90%. Do fewer things, better: Prioritize focus over breadth. Back the Team Collaborate for excellence: The whole is greater than the sum of its parts. Seek truth: Let the best ideas win, no matter where they come from, and let go of ego. Argue passionately, then commit fully: Debate fiercely, but once a decision is made, own it like it’s yours. Drive the Mission Advance AI safety: Every action should contribute towards the safe development of AI. Go big or go home: “The people who are crazy enough to think they can change the world are the ones who do.”
