Sr. Data Scientist

Brief Description :

NexTier's Completions Data Science team brings together talented, driven professionals who turn complex operational data into clear insights and empower our organization to make smarter, data-backed decisions every day. You will work specifically with Operations and Maintenance departments to develop physics-driven models and reliability frameworks that predict equipment behavior and optimize maintenance strategies for our frac fleet.

Detailed Description :

In this role you will collaborate with Program Managers to lead the strategy and execution of hybrid physics and machine-learning models for equipment reliability. You will design and run first-principles simulations, integrate high-frequency telemetry into digital twins, deploy scalable model pipelines in the cloud and validate predictions against field data.

Key Responsibilities :

• Define and guide the development of physics-ML reliability models (Weibull analysis, survival modeling, FMEA)
• Perform fluid-mechanics and mechanical simulations in Python or MATLAB and integrate outputs with telemetry streams
• Architect, deploy and monitor model training and serving pipelines on GCP AI Platform or Dataiku
• Establish validation protocols by coordinating with subject-matter experts to calibrate model assumptions
• Partner with maintenance, operations and field teams to align modeling efforts with business needs and data availability
• Identify new digital-twin use cases and build proof-of-concepts for early-warning systems and maintenance optimization
• Present technical findings to operations leadership, maintenance planners and engineering management
