Company Description 

FL121 is a privately held biotechnology company engineering nature to build next generation peptide therapeutics. By harnessing naturally occurring chemistry and pairing it with sophisticated high-throughput screening technology, we will unlock the future of de novo drug design via curated data creation and model training.  

Role 

FL121 is seeking a talented and highly motivated Director (Data Science/ Machine Learning). We’re looking for a resourceful computational problem solver and agile leader, someone who is not only scientifically rigorous and accountable for their and their team’s work, but also has a high EQ and is a motivating force within cross-functional teams. The ideal candidate brings a track record of building computationally strong data environments, developing predictive models based upon internal and external databases, driving results in a fast paced and demanding environment, and enabling others to do their best work, all while communicating with clarity and empathy. 

Key Responsibilities 

• Pioneer and lead computational efforts for FL121’s platform science
• Develop a data-framework and database for tracking DNA translation to chemistry, and chemistry to drug-characteristics in partnership with platform team
• Strategically map out chemical representation optionality and develop framework for platform chemistry that can scale with data
• Lead base-case chemical prediction models that can scale with data and forecast and scope data needs to enable models to have strong predictive power
• Build and support computational capabilities to unlock de-novo mass spec deconvolution models
• Integrate computational efforts across all platform workstreams to create a cohesive data-collection and integration workplace
• Serve as a cross-functional program lead, guiding interdisciplinary teams of computational scientists, mass-spec scientists, medicinal chemists, and synthetic biologists toward shared goals.
• Communicate computational goals, progress, and key decisions clearly across audiences, from scientists to executives, tailoring messaging with clarity and intention.

Professional Experience and Qualifications 

• Masters or PhD in a relevant field (e.g., computational chemistry, machine learning, data science, etc) with 10+ years’ experience in scientific/engineering/computational settings in biotechnology settings; industry AI/ML experience preferred  

• Experience driving results directly or indirectly through teams of scientists and engineers in varied technical environments
  
  
• Depth across multiple core tools and concepts, including, Python, modern ML frameworks (RDKit, scikit-learn, Chemprop, etc), version control, databases, deep learning architectures, and relevant informatics software (AWS, Seqera, Benchling, etc)

• Demonstrated success as a team-oriented leader who motivates others and builds strong, trust-based relationships across functions 

• Proven ability to lead complex, cross-functional programs balancing scientific vision with disciplined execution and strategic resource management 

• Track record of intellectual agility and curiosity, with an ability to adapt quickly, think critically, and lead through ambiguity. 

• Strong emotional intelligence, with demonstrated maturity in navigating interpersonal dynamics, providing feedback, and supporting the growth of PhD and non-PhD scientists. 
• Exceptional communication skills, both written and verbal, with a consistent ability to convey complex ideas clearly and succinctly to diverse stakeholders.
  
  
• A people-first, enterprise-minded approach that uplifts others, builds cohesion, and drives a culture of collaboration and accountability.
