About QuantHealth

QuantHealth is a fast-growing AI company transforming drug development through clinical simulations, predictions of disease progression and treatment effects, and large-scale biomedical AI. 
Our platform combines real-world patient data from over 350 million patients, biomedical knowledge graphs, and advanced machine learning models to simulate clinical trials and predict
patient outcomes. Pharmaceutical companies use QuantHealth platform to optimize trial design, reduce development risk, and accelerate the development of new therapies.
At the core of our platform is a family of proprietary AI models that learn from large-scale longitudinal healthcare data and biomedical knowledge to model disease progression, treatment effects, and clinical trial outcomes.

About the Role

We are looking for a Senior AI Research Engineer to help develop the next generation of QuantHealth’s core AI technology.
This is a highly technical, hands-on role focused on advancing our foundation models and predictive modeling capabilities. You will work closely with the Director of AI & Algorithms
and a team of researchers and engineers to develop novel machine learning approaches that improve how clinical outcomes, treatment effects, and patient trajectories are modeled.
The ideal candidate combines strong research instincts with exceptional implementation skills. You are comfortable reading and evaluating cutting-edge research, designing new modeling
approaches, and turning ideas into robust, production-ready systems. This role is primarily an individual contributor position, with a strong emphasis on research,
experimentation, algorithm development, and technical execution.

  and learning strategies.
• Develop rigorous validation methodologies and contribute to benchmarking and
  evaluation frameworks.
• Implement research ideas efficiently and at high-quality using modern machine learning
  frameworks.
• Collaborate closely with Clinical Teams, DataOps, MLOps, Product, and Engineering
  teams.
• Stay current with advances in machine learning and identify opportunities to incorporate
  relevant innovations into QuantHealth’s platform.
• Communicate technical findings clearly and proactively raise risks, limitations, and
  opportunities when identified.
• Contribute to scientific publications, patents, and external thought leadership initiatives
  when appropriate.
