Causal Inference Jobs in Florida (NOW HIRING)

One of Infonet's premier clients has an opening for a Sr. Data Scientist. (0513-1)

TERMS: Contract (Eligible for Conversion to Hire)
RATE: $90/hr 1099/Corp-to-Corp or $83/hr-W2

JOB LENGTH: 6-12 Months

SCOPE OF WORK

• Seeking a Sr. Data Scientist to serve as a senior owner for production data science outcomes, combining advanced modeling, experimentation, optimization, and stakeholder leadership to deliver measurable value across business processes across the company.
• Accountable for senior independent model ownership, cross-functional influence and expected to operate at the level of 4–8 production models, decision engines, experiments, or GenAI workflows across one or more domains, with influences experimentation cost, model operating cost, and build-versus-buy recommendations for owned work.
• The role differentiates Data Science ownership of problem framing, model behavior, experimentation, value measurement, adoption, and production model health from AI Engineering ownership of scalable platform foundations.
• Sr. Data Scientist will partner closely with domain leaders, product owners, AI engineers, data engineers, and senior business stakeholders to convert analytical rigor into decisions, workflow change, and measurable performance improvement

RESPONSIBILITIES

• Own problem framing for 4–8 production models, decision engines, experiments, or GenAI workflows across one or more domains by quantifying baselines, decision points, adoption paths, and expected value before modeling begins, with outcomes tied to multi-process improvements in revenue, cost, service, capacity, personalization, or operational decision quality
• Develop and validate high-performing predictive models using Python, scikit-learn, XGBoost, LightGBM, CatBoost, Databricks, feature stores, and robust backtesting appropriate to production decisioning
• Design optimization, recommendation, simulation, or scenario-planning engines that translate predictions into actions, constraints, tradeoffs, and measurable operational or commercial lift
• Build GenAI use cases with GPT-class models, Azure AI Foundry, RAG, embeddings, prompt libraries, evaluation harnesses, and safety tests, focusing on business process improvement rather than novelty
• Lead experimentation strategy using A/B tests, causal inference, quasi-experimental designs, bootstrap methods, and sensitivity analysis to prove whether interventions drive incremental value
• Create trust mechanisms using SHAP, counterfactual analysis, model cards, residual/error analysis, human review loops, and stakeholder-ready narratives that expose limitations and decision implications
• Partner with AI Engineering to productionize models through Databricks, Azure ML, MLflow, APIs, batch scoring, or containerized services while maintaining ownership of model quality, value, and adoption
• Own post-launch model health by monitoring accuracy, drift, calibration, bias, adoption, financial KPIs, latency, and cost, then driving retraining, rollback, or operating-process changes
• Lead cross-functional adoption with business, product, operations, AI Engineering, and data engineering teams so model outputs become decisions, workflow changes, and measurable performance improvements

REQUIRED SKILLS / EXPERIENCE

• Proven experience at senior scope delivering 4–8 production models, decision engines, experiments, or GenAI workflows across one or more domains, including production use, stakeholder adoption, value tracking, model operations, and measurable improvement in business outcomes
• Advanced experience with Python, scikit-learn, XGBoost, LightGBM, CatBoost, PyTorch/TensorFlow where relevant, model evaluation, hyperparameter tuning, backtesting, and feature engineering
• Strong experience applying MILP, simulation, dynamic programming, heuristics, stochastic methods, or prescriptive analytics to constrained, high-value business decisions
• Advanced experience with Azure AI Foundry, GPT-class models, RAG quality measurement, embeddings, prompt/version control, evaluation, safety testing, and workflow automation
• Deep hands-on experience with Databricks, Spark, SQL, feature stores, data quality checks, reproducibility patterns, and large-scale analytical pipelines
• Advanced experience with MLflow, Azure ML, model registries, CI/CD gates, monitoring, retraining triggers, rollback plans, and production ownership routines
• Strong production-oriented Python discipline, including modular code, testing, Git workflows, packaging, APIs, documentation, and collaboration with AI Engineering on scalable deployment patterns
• Executive-ready communication skills tailored to domain leaders, product owners, AI engineers, data engineers, and senior business stakeholders, with the ability to translate

PREFERRED EDUCATION

• Bachelor’s or Master’s degree in Data Science, Statistics, Computer Science, Operations Research, Engineering, Economics, or related quantitative field, or equivalent experience delivering production models at comparable scale
