Bayesian optimizationPythonpandas
About the Role
Ambyint seeks a Senior Data Scientist to develop Bayesian optimization and probabilistic models for industrial optimization in oil and gas production. The role focuses on estimating impact of operating changes from sparse field data and building trustworthy recommendations.
Key Skills for This Role
Bayesian optimizationPythonpandasNumPyscikit learnSQL
Responsibilities
- Develop Bayesian optimization workflows for artificial lift optimization across gas lift, plunger lift, rod lift, and hybrid lift systems
- Build probabilistic surrogate models that estimate production response, uncertainty, and risk from sparse and noisy field data
- Design constrained optimization policies that account for operational limits, safety constraints, trust regions, and field approved action ranges
- Model intervention response data using before/after windows, event quality flags, counterfactual baselines, and uncertainty aware targets
- Develop contextual models that condition recommendations on current well state, lift regime, production trends, pressure behavior, and plunger cycle performance
- Evaluate model calibration, predictive uncertainty, out of sample generalization, and decision quality across wells and operating regimes
- Help design field experiments and sequential learning workflows that balance exploration, exploitation, and operational risk
- Build diagnostics for model performance, uncertainty calibration, coverage, residuals by well, response heterogeneity, and support distance
- Collaborate with SMEs and operators to translate model outputs into practical recommendations, risk flags, and decision explanations
Requirements
- Strong academic or applied background in Statistics, Mathematics, Engineering, Physics, Operations Research, Econometrics, or another highly quantitative field
- Solid understanding of machine learning fundamentals and strong Python programming skills (pandas, NumPy, scikit learn)
- Experience working with messy real world datasets, especially time series, sensor, operational, or event based data
- Comfort working with SQL or structured data sources
- Proven experience evaluating models beyond simple accuracy metrics
- Ability to reason from first principles about assumptions, noise, uncertainty, bias, and model failure modes
- Strong communication skills to translate complex statistical outputs for technical and non technical stakeholders
- Willingness to learn new advanced modeling approaches (e.g., BoTorch/GPyTorch stack and Bayesian workflows)
Full Job Posting
Company Overview
- Ambyint is a SaaS company providing an Industrial IoT platform with physics influenced AI models and closed loop control for autonomous operations in the energy industry.
- The company is a market leader in production optimization, combining advanced physics, subject matter expertise, and data informed insights with AI.
What You’ll Do
- Develop Bayesian optimization workflows for artificial lift optimization across gas lift, plunger lift, rod lift, and hybrid lift systems.
- Build probabilistic surrogate models that estimate production response, uncertainty, and risk from sparse and noisy field data.
- Design constrained optimization policies that account for operational limits, safety constraints, trust regions, and field approved action ranges.
- Model intervention response data using before/after windows, event quality flags, counterfactual baselines, and uncertainty aware targets.
- Develop contextual models that condition recommendations on current well state, lift regime, production trends, pressure behavior, and plunger cycle performance.
- Evaluate model calibration, predictive uncertainty, out of sample generalization, and decision quality across wells and operating regimes.
- Help design field experiments and sequential learning workflows that balance exploration, exploitation, and operational risk.
- Build diagnostics for model performance, uncertainty calibration, coverage, residuals by well, response heterogeneity, and support distance.
- Collaborate with SMEs and operators to translate model outputs into practical recommendations, risk flags, and decision explanations.
Qualifications
- Strong academic or applied background in Statistics, Mathematics, Engineering, Physics, Operations Research, Econometrics, or another highly quantitative field.
- Solid understanding of machine learning fundamentals and strong Python programming skills (pandas, NumPy, scikit learn).
- Experience working with messy real world datasets, especially time series, sensor, operational, or event based data.
- Comfort working with SQL or structured data sources to extract and manipulate complex data.
- Proven experience evaluating models beyond simple accuracy metrics, including residual analysis, cross validation, subgroup performance, calibration, and error analysis.
- Ability to reason from first principles about assumptions, noise, uncertainty, bias, and model failure modes.
- Strong communication skills with the ability to translate complex statistical outputs into practical concepts for both technical and non technical stakeholders.
- Willingness and ability to learn new advanced modeling approaches (such as BoTorch/GPyTorch stack and Bayesian workflows).
What Sets You Apart
- The gratification of a job well done comes from the satisfaction of your ‘customers’—field operators and engineers trusting your models.
- You don't just import model APIs; you have a deep curiosity for why a model works, when it fails, and how to prove it's operationally safe.
- You possess a strong sense of uncertainty awareness and pragmatic judgment around whether a model output is genuinely useful in a physical environment.
- Continuous learning and improvement are part of your mantra; you are excited to bridge the gap between advanced statistics and real world industrial machinery.
- You are curious, creative, biased for action, and love solving problems where data is messy and answers aren't obvious.
- You have a background or familiarity with time series forecasting, anomaly detection, causal inference, or estimating the impact of operational interventions.
What’s In It For You
- Opportunity to make a difference in a cutting edge technology company focused on the energy transition.
- Hybrid working environment with a diverse and talented team.
- Competitive compensation and benefits package.
- Support for development and career goals.
