Machine Learning Scientist

What if you could join a rapidly growing company and play a critical role in bringing new medicines to patients through looking at and treating disease in a revolutionary way.

What this position is all about:

We seek a Machine Learning Scientist to build intelligent AI agent systems and develop machine learning solutions for drug discovery. You'll create AI systems that integrate biological data, mine scientific literature, and enable sophisticated reasoning to accelerate therapeutic development. The initial focus will be on building AI agent systems, with the role expanding into hands-on model development for high-dimensional biological data over time.

The work is hands-on and requires skills across a broad range of machine learning techniques. The successful candidate will work closely with researchers in biology, chemistry, and omics technology in a collaborative environment.

What you would be responsible for:

• AI Agent Development
  • Design and build intelligent agent systems for data integration, literature mining, and scientific reasoning
  • Create automated workflows that connect diverse biological resources and support discovery decisions
  • Develop scalable AI solutions that enhance research productivity and scientific insights
• Machine Learning & Data Science
  • Apply statistical methods to evaluate and prepare complex biological datasets (single-cell or bulk RNA-seq, phenotypic data, etc.) for ML applications
  • Build, train, and optimize models for high-dimensional biological data
• Scientific Collaboration
  • Partner with biology, chemistry, and technology teams to translate research questions into ML solutions
  • Communicate technical concepts clearly to diverse scientific audiences
  • Contribute to roadmap planning and strategic technical decisions

What experiences will you need:

• PhD in Computer Science, Computational Biology, or related field, OR Master's degree with 3+ years of relevant industry experience
• Strong programming skills in Python with experience in ML frameworks
• Experience with high-dimensional biological data analysis (bulk/single-cell RNA-seq, etc.)
• Proven track record in deep learning model development and deployment
• Strong mathematical foundation in statistics and machine learning
• Excellent communication skills and ability to work in interdisciplinary teams

What sets you apart:

• Experience with large language models (LLMs)
• Experience with MLOps tools and practices
• Experience designing and implementing multi-agent systems and reasoning frameworks

What it’s like to work at Cellarity

At Cellarity, we

• Push Boundaries: We create a legacy with breakthrough science in service of patients.
• Inject Energy: We build strengths from different perspectives and tell it like it is
• Own it: We transcend our job descriptions and relentlessly follow through on our commitments.
• Go all out: We work quickly and with conviction.

Company Summary: Cellarity’s mission is to fundamentally redesign the way drugs are created for the sake of bringing new hope to patients.  By shifting the focus from a single target to the underlying cellular dysfunction, we unravel the complexity of disease biology and create medicines that were never before possible. The company has developed unique capabilities that link biology and chemistry with high dimensional -omic data from which we design medicines against the cellular signature of disease. The Cellarity platform allows us to uncover new biology in diseases even in the absence of known causal targets. Cellarity is a privately held, clinical-phase drug discovery startup using AI and single-cell omics to develop life-changing medicines that are unreachable by traditional methods of drug discovery. Cellarity is a product of Flagship Pioneering's venture creation engine, which has conceived and created companies such as Moderna (NASDAQ: MRNA), Generate: Biomedicines, and Lila Sciences.

Cellarity is committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.

Recruitment & Staffing Agencies: Cellarity does not accept unsolicited resumes from any source other than candidates.
