Job description

Staff AI/ML Engineer, Applied AI Work Schedule Standard (Mon-Fri) Environmental Conditions Office Job Description About the Role At Thermo Fisher Scientific, you’ll do meaningful work that makes a positive global impact. Join our colleagues in bringing our Mission to life every single day to enable our customers to make the world healthier, cleaner, and safer. With industry-leading R&D investment, we empower our teams to solve complex scientific challenges—from environmental protection to advancing healthcare and cancer research. As a Staff AI/ML Engineer, Applied AI, you will provide hands-on technical leadership across the design, development, evaluation, and production deployment of advanced AI/ML solutions. You will architect and build machine learning and deep learning models, Large Language Model (LLM) applications, Retrieval-Augmented Generation (RAG) solutions, and agentic workflows that drive business insights, enhance scientific workflows, and improve customer experiences. You will work across the AI/ML lifecycle – from ideation, research, and experimentation through data engineering, model development and optimization, evaluation, performance tuning and deployment. Partnering closely with data scientists, software engineers, product teams and scientific stakeholders, you will translate complex business and scientific needs into scalable, reliable, and impactful AI/ML capabilities. This is a deeply hands-on individual contributor role with significant technical leadership responsibilities. You’ll also mentor engineers, influence platform strategy, and ensure AI-driven systems are accurate through consistent evaluation frameworks, engineering standards and technical best practices. A successful candidate in this role is expected to collaborate effectively with the broader teams, and consistently deliver well-architected, scalable, secure, production-grade AI and Generative AI features supporting a variety of use cases and scientific products, with measurable impact on scientific workflows, customer outcomes and innovation velocity.

Job Description:

Key Responsibilities

• Lead activities across the AI/ML lifecycle – from ideation, research, data engineering, model development and optimization, evaluation, performance tuning and deployment, while continuously engaging customers to gather feedback and incorporate it into solution development.
• Iteratively develop, deploy and scale AI/ML models and solutions across life sciences, genomics, material sciences, and healthcare.
• Provide technical leadership for AI/ML models, platforms, and solutions, including defining reference model and system architectures, software design standards, reusable patterns, and best practices for AI and Generative AI solutions.
• Champion an evaluation-driven approach to AI/ML solution development, establishing rigorous evaluation practices and promoting their consistent adoption across the organization.
• Build and deploy LLM-powered services using Azure OpenAI, Anthropic Claude, and OpenAI-compatible APIs.
• Architect and implement agentic AI and RAG workflows, including data ingestion, chunking, embeddings, vector search, retrieval, tool calling, memory, and prompt engineering.
• Design, develop, and integrate Generative AI systems using LangChain and LangGraph for agentic workflows and orchestration.
• Integrate AI/Generative AI capabilities into enterprise platforms, scientific applications and end-to-end workflows.
• Mentor and guide engineers across the AI/ML lifecycle, including model development, evaluation, and implementation of AI solutions.
• Actively participate in Communities of Practice, influencing engineering standards and AI/Generative AI adoption strategies across the organization.
• Communicate effectively with technical and non-technical stakeholders through clear documentation, architecture diagrams and design reviews.
• Stay current with advancements in AI/ML, Generative AI, agentic frameworks, and LLM ecosystems, and apply relevant innovations to enhance internal tools, scientific solutions and customer-facing products.

Candidate Requirement

Education and Experience: Master’s degree in AI/ML, computer science, statistics, engineering, or a related technical field. Ph.D. degree preferred. 10+ years of industry experience in software engineering and developing AI/ML solutions, with a strong track record of shipping AI/ML solutions into real production systems in a robust experimentation framework, not just offline analyses or research prototypes. 5+ years of experience working in agile/scrum environments.
