Data Scientist

We’re looking for a **mid-to-senior AI Engineer** with strong backend skills and experience in either **LLM-based systems** or **physiological signal processing** to join our team full-time in Dehradun. You’ll help us build production-ready AI solutions that serve both our mobile app and our health monitoring tools.

You’ll work alongside a focused and collaborative team to build tools that power AI features for real-time insights, personalized recommendations, and health predictions. This is a research-heavy, hands-on engineering role requiring the ability to read papers, design prototypes, build robust APIs, and ship features into production.

**What You’ll Work On**

LLM-Focused Workstreams

- Analyze user health data (metrics, goals, activity)
- Recommend content from our health library (videos, articles)
- Generate structured meal plans
- Design APIs and integrate AWS serverless infrastructure for our mobile app
- Develop RAG pipelines or vector DB-based solutions if applicable

Computer Vision & Signal Processing Workstreams
- Improve and expand our physiological signal extraction models (e.g., rPPG for heart rate)
- Build ML models to predict health vitals and risk markers from video data
- Validate models using appropriate metrics (AUC, ROC, sensitivity, etc.)
- Maintain reproducibility through experiment tracking and rigorous documentation

**Tech Stack**
- **Languages/Tools**: Python, Jupyter, GitHub, JSON, REST APIs
- **Frameworks**: scikit-learn, NumPy, pandas, OpenCV, (Optional: PyTorch/Keras)
- **Cloud & Infra**: AWS Lambda, S3, (Optional: Bedrock, LangChain, Vector DBs)

**What We Are Looking For**:
**Must-Haves**:

- 3-4+ years of backend or applied ML development using Python
- Experience with LLMs (e.g., LangChain, Bedrock, OpenAI APIs) or computer vision/signal processing
- Familiarity with structured data handling (REST, JSON) and serverless architectures (AWS Lambda)
- Strong grasp of ML model evaluation and ability to translate messy real-world data into clean pipelines
- Collaborative mindset with strong communication skills
- Comfortable working night shifts and from our Dehradun office

**Nice to Have**:

- Experience with physiological signal extraction or biomedical ML
- Knowledge of RAG pipelines, vector databases
- Contributions to peer-reviewed research or healthcare AI projects
- Interest in healthcare, nutrition, or wellness industries

We are looking for individuals who are not just technically skilled, but also aligned with our work culture and values:

- **Work from Office**: Willing to work full-time from our Dehradun office (No remote option).
