Description

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’—in this case, 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 SETS US APART Ambyint is a scale-up company, possessing all the exciting edginess of a start-up with solutions that are proven and advancing daily. We pride ourselves on the strength of our team and company, and the positive environmental impact we are driving. We live by a simple and effective set of values.
