• Agentic AI Frameworks:
• Build, manage, and orchestrate agentic workflows involving tool calling, reasoning loops, memory management, skills orchestration, and multi-step task execution.
• AI Safety & Reliability: Implement guardrails, monitoring, and validation mechanisms to ensure AI systems remain safe, reliable, and ethically grounded.
• This position will focus on developing new approaches to scientific software as part of a larger, dynamic development team dedicated to delivering high-quality, on-time software releases using best-of-breed Agile practices.
• The qualified candidate will have an excellent background in Python AI/ML programming, including AI-assisted coding.
• Familiarity with software architecture, design, optimization, and maintenance.
• In addition to being a hands-on engineer, the successful applicant will develop collaborative working relationships with application development, quality assurance, product marketing, technical communications, and technical services teams across the company.

Qualifications

• Master's degree or above, with 3+ years of software development experience and relevant experience specifically within the AI/ML development landscape.
• AI/ML Literacy: A strong grasp of LLM fundamentals, including tokens, temperature, top-p, and context windows.
• Experience implementing Retrieval-Augmented Generation (RAG) systems, semantic search, and vector databases.
• Prompt Engineering & Evaluation: Design, optimize, and evaluate prompts to improve AI behavior, reasoning, and response quality.
• Agentic AI Frameworks: Hands-on experience working with agentic AI frameworks such as LangChain, LangGraph, and DeepAgents, involving tool calling, reasoning loops, memory management, skills orchestration, guardrails, and multi-step task execution.
• Experience with Model Context Protocol (MCP).
• Familiarity with the use cases, processes, and methods used within the pharmaceutical and biotech industries, as well as by cheminformaticists and computational chemists, is a major plus.
• Broad technical knowledge of object-oriented design and implementation, design patterns, and software development methodologies.
