About BayRock Labs

At BayRock Labs, we pioneer innovative tech solutions that drive business transformation. As a leading product engineering firm based in Silicon Valley, we provide full-cycle product development, leveraging cutting‑edge technologies in AI, ML, and data analytics. Our collaborative, inclusive culture fosters professional growth and work‑life balance. Join us to work on ground‑breaking projects and be part of a team that values excellence, integrity, and innovation. Together, let’s redefine what’s possible in technology.

We are seeking a highly experienced and expert Senior Data Scientist with a minimum of 6 years of hands‑on experience to lead the development and deployment of advanced machine learning solutions. The ideal candidate is an expert in predictive modeling, time‑series forecasting, and recommendation systems, with a strong focus on native and efficient ML development within the Snowflake Data Cloud (Snowpark). This is a critical MLOps role requiring deep expertise in managing the entire model lifecycle using tools like MLflow, and a proven ability to apply advanced modeling techniques, including reinforcement learning (RL), to solve high‑impact business challenges.

Key Responsibilities

Advanced Model Development & Leadership

Design, develop, and implement production‑ready machine learning models for core business challenges, including :

Prediction (e.g., customer churn, risk, conversion).

Forecasting (e.g., demand, resource planning) using advanced time‑series methods.

Recommendation systems (e.g., content, product matching).

Lead advanced modeling initiatives : research, prototype, and implement cutting‑edge techniques such as reinforcement learning (RL) for sequential decision‑making problems (e.g., dynamic pricing, inventory optimization).

Apply expert‑level knowledge of deep learning and other complex algorithms to drive innovation and competitive advantage.

Lead the entire model development lifecycle, from ideation and feature engineering to deployment and monitoring.

Native Snowflake ML & MLOps Excellence

Snowflake native ML development : drive efficient and native ML development by utilizing Snowpark (Python, Scala, or Java) and Snowflake ML functions (e.g., FORECAST, Model Registry) for data processing, model training, and inference directly within the Snowflake Data Cloud.

MLOps and production engineering : own and automate end‑to‑end ML pipelines, ensuring scalability, low latency, and high reliability.

Implement rigorous model optimization and performance tuning to ensure maximum efficiency and minimal cost within the Snowflake compute environment.

Utilize MLflow (or similar tools like the Snowflake Model Registry) for comprehensive experiment tracking, model versioning, and governance.

Expertly leverage Snowflake for large‑scale data wrangling, feature engineering, and collaboration with data engineers to establish and integrate a robust, production‑ready feature store into the ML workflow.

Conduct A / B testing and rigorous experimental design to scientifically validate the business impact of deployed models and features.

Core Technical Expertise (Must Haves)

Expert proficiency in Python and its data science ecosystem (Pandas, NumPy, scikit‑learn, TensorFlow, etc.).

Expert proficiency in SQL and experience optimizing queries for cloud data warehouses.

Deep hands‑on experience with Snowflake for data preparation and ML, including Snowpark.

Proven experience with MLOps tools and practices, especially MLflow for model.

Advanced expertise in implementing and tuning predictive models, time‑series, and recommendation systems.

Practical experience in advanced modeling beyond classical ML (e.g., deep).

Demonstrated experience with reinforcement learning (RL) algorithms (e.g., Q‑learning, policy gradients) and frameworks (e.g., Stable‑Baselines, Ray) for real‑world application.

Experience with cloud computing platforms (AWS, Azure, or GCP) for
