Curated JD: Is this a pure play technical/techno functional role?: Technical role. Specific contribution expected from the role: Seeking a Stan Developer / Bayesian Statistical Modeler with robust expertise in Stan, Bayesian modeling, hierarchical/time-series/spatial models, and probabilistic programming to design and implement production-grade statistical models. Hands-on experience with MCMC, HMC/NUTS, convergence diagnostics, variational inference, optimization, custom log-probability functions, and model performance tuning is required. Proficiency in R or Python, Cmd Stan/Cmd Stan Py/Cmd StanR, C++, Git, CI/CD, Docker, and parallel processing/GPU acceleration, with the ability to translate Bayesian insights into actionable business outcomes. Location: Remote. Shift Timing: Normal (Day Shift). End of Curated JD. Job Description: Key Responsibilities Statistical Model Design: Formulate, implement, and validate complex Bayesian models (e.g., hierarchical models, time-series, spatial models, mixture models) in Stan.
Algorithm & Performance Tuning:



Optimize model execution time and convergence using advanced Stan features, parameterization techniques (e.g., non-centered vs. centered parameterizations), and custom C++ functions where appropriate. Sampling & Diagnostics: Execute and monitor MCMC sampling (NUTS/HMC) and optimization routines; perform rigorous convergence diagnostics (e.g., R-hat, ESS, divergence checks, posterior predictive checks).
Environment Integration: Interface Stan models with production data pipelines using RStan, PyStan, Cmd Stan, or Cmd Stan Py. Collaboration & Communication: Translate complex probabilistic outputs and uncertainty estimates into actionable, clear insights for stakeholders and cross-functional engineering teams. Required Qualifications Probabilistic Programming: Hands-on experience developing, debugging, and optimizing Bayesian statistical models directly in Stan.
