Job summary

Schwab Technology Services seeks a Senior AI & Data Scientist to design, build, and scale enterprise AI solutions. You will own end‑to‑end model lifecycles, collaborating with sponsors and engineering teams to deliver measurable value in a regulated financial environment.

You’ll lead ML systems, NLP, and LLM‑enabled workflows with strong MLOps practices, CI/CD, and production‑grade quality. On‑site in Southlake, TX, with hybrid flexibility.

Qualifications

• Experience in data science and machine learning.
• Advanced degree (Master’s or PhD) in a quantitative field such as computer engineering, statistics, mathematics, physics, chemistry, or related discipline.
• Hands‑on experience using Python and SQL to develop production‑grade, modular, and optimized code.
• Proven ability to convert business requirements into technical end‑to‑end machine learning solutions delivered against roadmap milestones for two or more lines of business.
• Proven experience developing supervised and unsupervised machine learning solutions, with delivery of three or more distinct models supported by documented evaluation metrics, performance tracking, and value measurement.
• Experience in applying natural language processing techniques to unstructured data with at least one solution delivered to production.
• Practical experience designing LLM solutions (such as retrieval‑augmented generation, agent workflows, or fine‑tuning), including at least one LLM system deployed for internal use.
• Strong software engineering fundamentals, including version control, CI/CD, and MLOps practices, demonstrated through three or more production deployments.

Responsibilities

• Get hands-on with big data as you analyze, interpret, extract insights, and produce innovative AI solutions that enable advanced decisioning leveraging the latest algorithms, state‑of‑the‑art techniques, and tools.
• Design and build end‑to‑end machine learning systems by defining scalable, reliable, and maintainable architectures that support data ingestion, feature generation, model training, evaluation, deployment, monitoring, and value measurement in production environments.
• Translate business strategy into technical execution by partnering with business stakeholders to convert high‑level business objectives into clear, actionable data science and AI solutions that address critical business and technology challenges.
• Set and elevate engineering standards for data science by establishing best practices that treat data science as a rigorous engineering discipline, including modular code design, testing, version control, and production readiness.
• Advance technical capabilities in emerging areas by leading complex initiatives involving advanced machine learning, recommender systems, real‑time and low‑latency inference, or other evolving technologies that require deep technical expertise and comfort with ambiguity.
