Parametric believes each member of our organization makes a significant contribution to our success. That contribution should not be limited by the assigned responsibilities. Therefore, this job description is designed to outline primary duties and qualifications. It is our expectation that every member of our team will offer his/her/their services wherever and whenever necessary to ensure the success of our client services. ## Description This role is part of Parametric's hybrid working model, which includes working in the office 3 days a week and choosing to work remotely or in the office the remaining days of the week. ABOUT THE TEAM The Core Platform and AI Engineering team at Parametric is responsible for enhancing the quality and velocity of engineering outcomes across the technology organization through platform-level capabilities, accelerating engineering teams and enabling them to focus on delivering business value. This team delivers Parametric's platform-level service and development capabilities. These efforts seek to optimize the organization's technology posture by providing common solutions to shared problems, driving standardization, accelerated delivery, reduced risk and cost, and scalable, high-performing results. The team serves engineering teams across the organization and is responsible for supporting their success. ABOUT THE ROLE The Principal Software Engineer, AI Platform, will serve as the AI engineering team lead, acting as a core technical enabler across business units. This individual will apply deep knowledge of ML, NLP, transformer architectures, and LLMs to build Parametric's GenAI platform and design, evaluate, and operationalize generative AI solutions running on this platform. 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. This role will lead the engineering effort for Parametric's GenAI platform, supporting a wide range of production workloads in collaboration with internal engineering teams. The platform serves as the foundation for AI capabilities, operations, and governance within Parametric, enabling engineering teams to rapidly create safe, compliant, and highly effective GenAI-based solutions which directly solve business needs. Parametric values strong software engineering and takes pride in its 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 RESPONSIBILITIES * Provide technical leadership by directly managing a team of engineers, guiding and mentoring them to achieve their highest potential while collectively advancing the goals and projects of the engineering team. * Drive vision and strategy for the team while exemplifying strong leadership skills, including communication, consensus building, elevated standards, ownership, accountability, and project management. * Lead GenAI development projects, including all components of the development lifecycle, from requirements gathering to deployment, bug fixes, enhancements, and escalated support. * Work directly with business users and engineering teams to build strong relationships, understand requirements, scope solutions, and communicate technical trade-offs in accessible terms. * Design, develop, and maintain high-quality and flexible platform-level technical solutions to GenAI engineering problems, including reusable components, governance processes, model evaluation, services, and APIs. * Design, develop, and maintain platform-level GenAI applications leveraging prompt engineering, RAG pipelines, fine-tuning, and agentic workflows to drive business outcomes. * Translate business problems into technical solutions by assessing data availability, feasibility, and alignment with GenAI capabilities. * Support 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. * Conduct code and design reviews for developers working on generative AI solutions, ensuring adherence to our engineering best practices and evaluation standards. * Implement and manage cloud deployments using AWS services, ensuring high availability, scalability, and observability. * Maintain and enhance existing AI applications to improve model performance, reliability, and user experience through data-driven iteration. * Follow GenAI and related technology trends and recommend improvements to our systems when appropriate., Job Description: IPG's Material Processing Systems Group is focused on integrating state-of-the-art IPG lasers into turn-key systems to be used in the semiconductor, medical and … + 2 months ago ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Agentic employees in world's most downloaded FinTech app](https://www.wearedevelopers.com/videos/100123-agentic-employees-in-world-s-most-downloaded-fintech-app) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) - [Engineering Mindset in the Age of AI - Gunnar Grosch, AWS](https://www.wearedevelopers.com/videos/1735-engineering-mindset-in-the-age-of-ai-gunnar-grosch-aws) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [What Are Large Language Models?](https://www.wearedevelopers.com/magazine/304-what-are-large-language-models) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [What is Agentic Programming and Why Should Developers Care?](https://www.wearedevelopers.com/magazine/625-what-is-agentic-programming-and-why-should-developers-care)
