About the Role

Join the cross-functional Data Analysis team to develop optimisation and forecasting models that improve the movement of wafer lots through fabrication partners. Reduce cycle times, anticipate delivery milestones, and adapt lot priorities as fab conditions change. Your work will help answer key operational questions and shape how data science is applied across Xanadu.

Responsibilities

  • Own wafer-lot optimisation and forecasting models, defining objectives, constraints, trade-offs, and success criteria with engineering stakeholders.
  • Forecast lot milestones and completion dates, quantifying uncertainty as fab conditions change.
  • Optimise lot releases, priorities, and resource allocation under queue, hold, route, and capacity constraints.
  • Analyse operational and metrology data; use historical data and simulation to identify bottlenecks, validate models, and compare strategies against current practice.
  • Develop Python-based prototypes, documenting models and validation results for engineering handover.
  • Communicate actionable recommendations and limitations, measure operational impact, and refine models with stakeholder feedback.
  • Scope unfamiliar problems and adapt methods as evidence and priorities evolve.

Requirements

  • MSc/PhD, or BSc with equivalent industry experience, in a quantitative discipline.
  • 3+ years applying data science to scientific, engineering, or operational problems, with substantial experience in optimisation and forecasting.
  • Experience independently leading ambiguous modelling problems from formulation through validation to decisions informed by the results.
  • Strong statistical inference and predictive modelling skills, including uncertainty quantification, diagnostics, and validation.
  • Experience working with unstructured and incomplete data.
  • Ability to formulate constrained optimisation problems, select methods, and assess feasibility, sensitivity, and practical value.
  • Experience validating forecasts under changing conditions and incomplete observations while avoiding data leakage.
  • Proficiency in Python and reproducible model development, including version control, documentation, and testing; experience preparing datasets from multiple sources, including event histories.
  • Ability to collaborate across disciplines, communicate recommendations and limitations, and prioritise work by impact.
  • Experience transferring modelling methods across domains and learning unfamiliar subject matter.
  • Experience with mathematical or constraint programming, scheduling heuristics, stochastic or robust optimisation, or multi-objective optimisation.
  • Experience with manufacturing scheduling, capacity planning, supply-chain optimisation, discrete-event simulation, or queueing models.
  • Experience with time-to-event forecasting, including survival analysis.
  • Familiarity with semiconductor fabrication, photonics, process integration, or metrology, including using process data to guide wafer disposition.
  • Experience evaluating models with engineers and defining requirements for implementation.
