AI/ML Scientist / Engineer — LLM Post-Training

Sahai | eGovernments Foundation

About Sahai
Sahai is an initiative backed by the eGovernments Foundation, building an AI triage system and clinician co-pilot to expand primary healthcare access across rural India.
Through voice-based conversations, Sahai gathers patient histories and prepares differential diagnoses and draft care recommendations for qualified doctors to review. We are developing open-weight models suited to Indian primary care, supported by clinical data, safety controls, and rigorous evaluation.

The AI recommends. The doctor decides.

The Role
We are looking for a hands-on AI/ML Scientist / Engineer to develop and validate a proof-of-concept model for clinical interviewing and diagnostic decision support.
The challenge goes beyond teaching models medical facts. It involves improving their ability to conduct useful multi-turn patient interviews, work with clinical tools, and reason with incomplete information.
You will collaborate with clinicians, data specialists, and engineers to design experiments,



post-train candidate models, and establish what works. This role focuses on model research and development, not production deployment or operational infrastructure.

What You Will Do
• Post-training and alignment: Design and run experiments using supervised fine-tuning, reinforcement learning, preference optimization, and reward design.
• Agentic model development: Improve language models for sequential patient interactions and tool-augmented clinical workflows.
• Knowledge distillation: Explore transferring capabilities from larger teacher models into smaller, computationally effective models.
• Training data and simulation: Partner with clinical and data teams to develop curated datasets, synthetic conversations, and patient-simulation environments.
• Rigorous evaluation: Compare models and approaches through reproducible experiments, automated assessments, and clinical review.
• India-specific adapta
