Senior Software Engineer (GenAI) - Parametric

The Senior Software Engineer (Generative AI) will serve as a core technical enabler across business units, applying deep knowledge of ML, NLP, transformers, and LLMs to design, evaluate, and operationalize generative AI solutions.

This role bridges business stakeholders and engineering teams, translating business problems into technical solutions grounded in data availability and feasibility while enabling engineering teams to fully utilize the advanced AI capabilities available at Morgan Stanley. Through expertise in the AI development lifecycle, from problem framing through evaluation and regression testing, combined with a platform mindset, this role ensures Parametric's GenAI solutions are robust, measurable, and continuously improving.

Parametric values strong software engineering and takes pride in their culture of technical rigor, modern practices, and continuous growth. This role will help translate that culture into practical platform solutions which promote engineering effectiveness and consistent delivery.

PRIMARY RESPONSIBILITES

• Translate business problems into technical solutions by assessing data availability, feasibility, and alignment with GenAI capabilities.
• Own and drive the AI development lifecycle end\-to\-end: problem scoping, data assessment, solution design, implementation, evaluation, deployment, and iteration.
• Design and execute AI system evaluation frameworks, including quantitative metrics definition, discriminative testing (e.g., A/B, sensitivity analysis), regression testing, and continuous quality monitoring of GenAI outputs.
• Apply deep knowledge of ML, NLP, Transformer architectures, and LLM internals (tokenization, attention, decoding strategies, fine\-tuning paradigms) to select, adapt, and optimize foundation models (OpenAI, Llama, open source, etc.) for diverse use cases.
• Design, develop, and maintain platform\-level GenAI applications leveraging prompt engineering, RAG pipelines, fine\-tuning, and agentic workflows to drive business outcomes.
• Interact directly with business users and engineering teams to understand requirements, scope solutions, and communicate technical trade\-offs in accessible terms.
• Conduct code and design reviews for developers working on generative AI solutions, ensuring adherence to engineering best practices and evaluation standards.
• Implement and manage cloud deployments using AWS service, ensuring high availability, scalability, and observability.
• Maintain and enhance existing AI applications to improve model performance, reliability, and user experience through data\-driven iteration.
