Senior Applied Scientist

Relativity is a leading legal data intelligence company building technology that helps users organize data, discover the truth, and act on it with confidence. Our AI‑powered cloud platform, Relativity One, transforms massive volumes of complex information into actionable insights for litigation, investigations, regulatory inquiries, data breach responses, and other high‑stakes legal work where accuracy, trust, and accountability are critical.

Every year, the global justice system benefits from insights generated by Relativity AI across billions of documents. We are just getting started on our journey to use AI to improve the outcome of every discovery, investigation, and analysis performed on our platform.

At Relativity, we develop AI guided by our AI Principles. These principles ensure we build AI with clear purpose, empower customers with transparency and control, treat fairness and privacy as first principles, protect customer data by design, and act with a high standard of responsibility and accountability.

Relativity’s AI organization is focused on exploration, experimentation, and turning cutting‑edge research into real‑world impact. We believe innovation requires experimentation, learning, and iteration. Our teams experiment, evaluate, ship, and learn continuously while maintaining a strong commitment to responsible AI.

The Applied Science team operates at the core of Relativity’s AI development. Our team includes specialists with advanced postgraduate training and deep experience building and operating machine‑learning models  work closely with engineering, product, design, data engineering, machine‑learning operations, and LLM engineering teams to translate complex AI research into production‑ready features used by legal professionals around the world.

As a Senior Applied Scientist, Generative AI, you will design, build, and deploy generative and machine‑learning models that power Relativity’s next‐generation AI‑driven product capabilities. You will collaborate closely with applied scientists, engineers, product managers, and designers to build models that help legal professionals organize data, discover the truth, and act on it with confidence. This role balances research, development, and operational responsibility.

You will contribute to Relativity’s portfolio of transformational generative AI technologies while adhering to our responsible AI principles and ensuring models perform reliably in real‑world, high‑stakes environments.
