Title and Summary Senior AI Engineer Role Overview The Senior AI Engineer is responsible for designing, developing, deploying, monitoring, and continuously improving AI-enabled solutions that transform how Technology Regulatory Execution (TREx) delivers regulatory, customer, compliance, and risk management activities. This role combines strong software engineering, machine learning, generative AI, and automation capabilities to build scalable solutions that improve operational efficiency, enhance stakeholder experiences, and support regulatory excellence.
As part of Technology Regulatory Market Compliance (TRMC), the Senior AI Engineer will partner with business, risk, compliance, and technology teams to identify transformation opportunities and develop AI-powered products that modernize regulatory examinations, customer assurance activities, technology control oversight, regulatory readiness, and risk management processes. This is a hands-on engineering role responsible for the full AI solution lifecycle, including model development, prompt engineering, model evaluation, deployment automation, observability, performance monitoring, continuous improvement, and production support.
The successful candidate will leverage machine learning, generative AI, workflow automation, and cloud-based AI services to create innovative solutions that deliver measurable business outcomes while meeting enterprise governance, security, and compliance requirements. Key Responsibilities AI Solution Design & Development • Design, build, test, deploy, and support AI and machine learning solutions that improve the efficiency, quality, scalability, and consistency of TREx operations.
• Develop prototypes, proofs of concept, and production-ready AI applications addressing regulatory examinations, customer requests, risk assessments, governance processes, and compliance activities. • Design and implement generative AI solutions leveraging large language models (LLMs), retrieval-augmented generation (RAG), vector databases, knowledge repositories, and enterprise AI platforms. • Translate complex business requirements into scalable AI architectures and technical solutions.
• Develop reusable AI services, automation frameworks, prompt libraries, workflow templates, and accelerators that can be leveraged across multiple regulatory and risk domains. Model Building, Evaluation & Optimization • Build, train, evaluate, fine-tune, and optimize machine learning and generative AI models using established engineering and data science practices. • Apply iterative model development techniques, including experimentation, testing, refinement, retraining, and continuous performance improvements.
• Execute model evaluation processes using appropriate quality, accuracy, relevance, reliability, and business outcome metrics. • Implement prompt engineering, model tuning, and hyperparameter optimization techniques to improve solution effectiveness and efficiency. • Establish guardrails and validation mechanisms that promote responsible, secure, explainable, and compliant AI outcomes. AI Operations & MLOps • Design and manage MLOps practices that support the complete AI lifecycle, including automated testing, deployment pipelines, model versioning, monitoring, and governance.
• Develop CI/CD processes for AI solutions and integrate AI capabilities into enterprise technology platforms and workflows. • Implement telemetry, logging, observability, and monitoring capabilities th
