Sr. Manager Data Science - Gen AI & Content Sys.

Salary: $118,300 - 219,800 per year Requirements:

• We prefer an advanced degree such as a Masters or PhD in Data Science, Computer Science, Statistics, or a related discipline, or equivalent hands-on experience.
• A bachelors degree in a relevant field plus substantial practical experience in data science, machine learning, or AI is acceptable.
• We typically look for 8+ years of relevant experience in data science, machine learning, or applied AI.
• We typically look for 4+ years of leadership experience, either direct or indirect team management.
• We value demonstrated impact, technical depth, and leadership, including for candidates with non-traditional career paths.
• We need strong technical fluency with Python and LLM/ML tooling such as Google ADK, LangChain, TensorFlow, PyTorch, and prompt tuning methods.
• We look for familiarity with vector databases, knowledge graphs, and hybrid retrieval architectures.
• We require strong experience working with structured and unstructured data at scale.
• We need the ability to design and implement data pipelines and data preparation workflows.
• Experience integrating machine learning into complex, multi-stage processing systems is important.
• Working knowledge of containerization, CI/CD, RESTful API design, and model serving tools is expected.
• Cloud infrastructure experience with AWS is preferred, though Azure or Google Cloud Platform is also relevant.
• Familiarity with AI coding tools such as GitHub Copilot, Claude Code, or OpenAI Codex is helpful.
• A graduate degree in Computer Science, AI, Machine Learning, or equivalent experience is preferred.
• Experience in legal tech, legal AI, or document-heavy domains is highly desirable.
• Familiarity with ethical and legal considerations for deploying generative AI in professional environments is valued.

• We set the strategic vision and priorities for Data Science across our content ecosystem.
• We lead, mentor, and develop a team of data scientists and ML engineers while shaping the team culture.
• We drive applied research with a clear path to production, balancing innovation with latency, cost, and reliability constraints.
• We build and scale evaluation science, including offline evaluation frameworks, automated benchmarking, and human-in-the-loop feedback systems.
• We champion rapid prototyping, hands-on experimentation, and frequent iteration.
• We collaborate with other Data Science teams to reuse components and patterns and reduce duplication.
• We coordinate across multiple cross-functional teams, systems, and domains.
• We help define and execute the AI roadmap across the content lifecycle.
• We work on content collection and transformation, metadata extraction, enrichment, classification, and agentic workflows that convert real-world events and legal content into intelligence.
• We design and deploy scalable production-grade AI systems, including LLM-based document understanding and generation, RAG pipelines, hybrid ML and rules-based systems, and agentic workflows.
• We write code, build and demo prototypes, and contribute directly to experiments and production models.
• We establish best practices for model development, evaluation, monitoring, prompt engineering, experimentation, data preparation, feature engineering, and reusable platform components.
• We partner with engineering, architecture, and product leaders to integrate AI into large distributed systems and align technical solutions with business outcomes.
• We translate ambiguous challenges into clear plans and executable solutions, and guide teams through delivery.
• We present tradeoffs and alternative approaches when delivery constraints require practical decisions.
• We mentor and grow a multidisciplinary team focused on LLMs and ML engineering.
• We collaborate closely with legal subject matter experts, data engineers, product managers, and design partners.
• We establish evaluation, observability, and responsible AI practices.
• We oversee infrastructure that supports continuous delivery and production monitoring of LLM systems.
