ABOUT PIONEERING INTELLIGENCE

Pioneering Intelligence builds on Flagship Pioneerings legacy of founding cutting-edge science and computational ventures harnessing recent advances in AI machine learning and data to accelerate fundamental research and create a portfolio of AI-first companies. As part of Flagships integrated model of science entrepreneurship and capital it transforms breakthrough ideas into world-changing companies elevating the AI advances happening across the ecosystem in human health sustainability and beyond.

THE ROLE

We are seeking a Principal Scientist (Embedded ML/Computational) to lead multiple AI/ML or computational projects across early stage ventures as a part of Flagships company origination process. You will define and deliver pragmatic AI strategies oversee method and platform development (e.g. systems design drug design molecular modeling systems biology protein design LLM/agentic workflows) and ensure rigor in model development benchmarking scaling and reporting. You will manage cross functional contributors as applicable influence company direction and represent PI to venture teams and external partners. The ideal candidate is a self-directed serial deep diver - someone who can move from protein design one week to mass spec or docking pipelines the next and then spin up LLM based agents that automate scientific workflows.

KEY RESPONSIBILITIES

• Program Leadership: Lead development implementation control and reporting of several AI/ML or computational projects within assigned ventures in line with broader strategic plans of PI and Flagship budgets and timelines.
• Technical Ownership: Take a specialized technical role on project teams to oversee method development pipeline development and LLM based agent/workflow design; drive benchmarking scaling and implementation into production grade systems.
• Best Practices: promote operational excellence in AI projects by educating cross-functional collaborators.
• Team Leadership: Manage and/or coordinate internal and external scientists/engineers and crossfunctional project teams as applicable; mentor early hires; support recruiting and interview.
• Planning & Resourcing: Contribute to project planning including budgets resources and timelines; surface risks and tradeoffs early with clear options.
• Landscape & Strategy: Independently scout emerging literature and the AI/ML landscape; synthesize concepts to propose new development strategies and identify opportunities for PI and venture portfolios.
• Representation & Community: Represent PI to portfolio companies and external partners; act as a recognized subject matter expert; actively participate in scientific conferences and meetings.
• Communication & Influence: Influence the course of projects and technical approaches; adapt and present complex findings to diverse audiences to support meaningful interpretation and action.

PROFESSIONAL EXPERIENCE & QUALIFICATIONS

• Masters or PhD in a relevant field (e.g. machine learning mathematics statistics computational sciences) with 5 years experience scientific/engineering/computational in academic pharmaceutical or biotechnology settings; industry AI/ML experience preferred.
• Experience driving results directly or indirectly through teams of engineers/scientists in dynamic fastpaced entrepreneurial and technical environments.
• Clear evidence of sustained independent thought and creativity driving high impact cross disciplinary AI/ML projects.
• Successful track record of leadership and contribution to decision making on progression of AI/ML models within projects or programs.
• Depth across multiple core tools and concepts including Python; modern ML frameworks (PyTorch or JAX/TensorFlow); version control; databases; deep learning architectures; and relevant informatics software.
• Consistent record of outstanding performance reflected in publications patents or high impact internal reports where applicable

Preferred Qualifications

• Breadth across domains such as protein modeling/design proteomics/mass spec cheminformatics/docking/ADMET biophysics/MD and LLM/agentic automation.
• MLOps expertise: data contracts and lineage (e.g. DVC/LakeFS) experiment tracking (MLflow/W&B) secure AWS infrastructure (S3 Batch/ECS/EKS SageMaker) Docker IaC (Terraform/CDK) and CI/CD (GitHub Actions).
• Generative modeling (diffusion/flow/VAEs) for sequences graphs or 3D structures; docking rescoring (e.g. gnina DiffDock) and pose quality metrics.
• Workflow orchestration (Airflow/Prefect/Argo) data warehouses (Redshift/Snowflake) vector search (FAISS/pgvector) and lightweight internal tools (FastAPI Streamlit/Gradio).
• Experience mentoring early hires acting as interim Head of ML and contributing to hiring plans and interview processes at startups.

WHY PIONEERING INTELLIGENCE

• Operate at the frontier: Build and deploy AI/ML that directly powers discovery and decision making across multiple new ventures.
• Own the full stack: From scoping and data contracts to models MLOps and internal UIsship endtoend systems that scientists rely on daily.
• Compound impact: Convert one off wins into shared libraries and templates adopted across the PI portfolio.
• Work with founders: Partner closely with venture leadership and PI platform engineers; influence strategy through hands on delivery.
• Grow fast: Stretch across domains take on situational leadership present at conferences and help shape first ML teams.
