At EvenUp, we leverage the power of technology to bring fairness and accessibility to the legal system. Large language models (LLMs) and generative AI are the foundation of our technology strategy, especially in Document AI : the ability to deeply understand, reason across, and generate legal and medical documents at scale. This is one of the largest opportunities in applied AI, and one of the most impactful.

We are seeking a Principal Machine Learning Engineer, the highest individual contributor level at EvenUp, who will help define not just our technology roadmap, but the future of Document AI itself. This role is for someone who thrives on both vision and execution : pioneering new approaches in a fast-evolving field, while also shipping systems that redefine what is possible in legal technology.

Retrieval-Augmented Generation (RAG) : multi-hop retrieval, reasoning chains, and verifiable generation at scale.

Evaluation & Trust : systematic benchmarking, reliability, factuality, and risk assessment of LLMs in high-stakes legal and medical domains.

Efficient Training & Adaptation : parameter-efficient fine-tuning, distillation, multi-modal integration, and domain-specific pretraining strategies.

Shape EvenUps ML strategy and technical roadmap, working hand-in-hand with product, engineering, and leadership to ensure our Document AI capabilities directly drive company growth and customer impact.

Act as a company-wide thought leader in generative AI, providing strategic advice to executives and influencing not just what we build, but how we prioritize and compete.

Mentor and elevate the entire ML organization, fostering a culture of deep technical rigor, creativity, and excellence.

What we look for :

12+ years of experience in machine learning, with a proven record of shipping multiple systems at scale and advancing the state of the art.

Recognized expertise in large-scale ML and LLMs, with strong publication, patent, or open-source contributions a plus.

Strong track record of innovation in deep learning, generative models, reinforcement learning, or probabilistic methods, with direct impact on real-world systems.

Hands-on mastery of modern ML toolchains and programming (Python, PyTorch, TensorFlow, distributed training, large-scale data systems).

Exceptional ability to translate cutting-edge research into robust, practical solutions that move the needle for customers.

Demonstrated thought leadership and influence across organizations, with the ability to set standards and inspire others.
