FL| Cambridge, MA Senior Director​/Vice President, Machine Learning; Generative Chemistry

Cambridge, MA USA

FL117 , a venture-back stealth AI x bio startup, is seeking a highly skilled Sr. Director/VP ML, Generative Chemistry . Here you will lead AI/ML and cheminformatics projects building the next-gen multi-modal generative models for biomolecular design. You will define and deliver pragmatic AI strategies, oversee method and platform development (ex: systems design, drug design, molecular modeling, LLM/agentic workflows), and ensure rigor in model development, benchmarking, and scaling.

You will manage the computational team split across AI/ML, molecular simulations, and cheminformatics, directly influencing company building decisions. We are looking for independent leaders, excited to work on ambitious projects in a fast-paced environment to push the frontier of AI-powered drug discovery.

• 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 scientists and engineers and cross functional 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.

• MSc or PhD in Computer Science, AI/ML, Physics, Biophysics, or a related field
• 7+ years of experience scientific/engineering/computational in Pharma or Biotech settings; industry AI/ML experience preferred
• Experience driving results directly or indirectly through teams of engineers/scientists in dynamic, fast paced, entrepreneurial, and technical environments.
• Clear evidence of sustained independent thought and creativity driving high impact, across drug development and chemistry 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/Tensor Flow); 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
• Proven ability to lead technical initiatives, communicate progress, and drive innovation in generative biomolecular design

• Breadth across domains such as protein modeling/design, cheminformatics/docking/ADMET, biophysics/MD, and LLM/agentic automation. Please send us your Git Hub, if applicable.
• Strong presence in the ML community through publications and conference proceedings. Please send a list of publications, if applicable.
• MLOps expertise: data contracts and lineage (e.g., DVC/LakeFS), experiment tracking (MLflow/W&B), secure AWS infrastructure (S3, Batch/ECS/EKS, Sage Maker), Docker, IaC (Terraform/CDK), and CI/CD (Git Hub Actions).
• Generative modeling (diffusion/flow/VAEs) for sequences, graphs, or 3D structures; docking rescoring (e.g., gnina, Diff Dock) and pose quality metrics.
• Workflow orchestration (Airflow/Prefect/Argo), data warehouses (Redshift/Snowflake), vector search (FAISS/pgvector), and lightweight internal tools (FastAPI, Streamlit/Gradio).
• Familiarity with ML software development and cloud services (Docker, AWS Batch, Step Functions, EKS, AWS Parallel Cluster, etc.)
• Experience with librariers like: rdkit, rosetta, prody, biopython, pymol, openmm, dagster, prefect, etc.
• Experience mentoring early hires, acting as interim Head of ML, and contributing to hiring plans and interview processes at startups.
