Principal Machine Learning Engineer

About the Role

We are seeking a Principal Machine Learning Engineer to design, build, and operate scalable AI/ML systems and agentic architectures that support next‑generation legal research and analytics products. This role combines deep ML expertise with distributed systems engineering and AI platform development.

You will play a key role in developing enterprise‑grade AI systems, including large language model (LLM) infrastructure, retrieval‑augmented generation (RAG) pipelines, and autonomous agent frameworks designed for complex large unstructured data.

• Provide architectural direction and code‑level guidance.
• Establish engineering best practices for ML system design, testing, and deployment.
• Conduct design reviews, performance reviews, and technical roadmap planning.
• Architect distributed ML systems serving multiple global products.
• Standardize infrastructure patterns for LLM serving and retrieval systems.
• Define and implement enterprise‑ready agentic frameworks.
• Architect multi‑step reasoning systems.
• Lead decisions on deterministic workflows vs. autonomous agents.
• Implement guardrails, safety layers, and traceability mechanisms.
• Develop evaluation frameworks to measure reasoning quality, hallucination rates, and reliability.
• Establish CI/CD standards for ML lifecycle management.
• Ensure compliance with enterprise data governance and responsible AI standards.

• 10+ years of Machine Learning/Software Engineer experience.
• Master’s degree or bachelor’s degree in computer science is highly desirable.
• Strong software engineering background with experience in building system design, architecting AI feature/products that cater large number of users and deal with large volume of unstructured data.
• Experience with ML deployment to production.
