Submit your application for the opportunity below: Data Scientist II
As part of the Accelerated Technologies team, the Data Scientist II is responsible for designing, developing, validating, and supporting analytical and machine learning solutions using clinical, operational, and business data.
This position works closely with cross-functional teams to translate business and clinical needs into well-defined analytical problems, scalable data products, statistical models, and actionable insights. The Data Scientist II will apply statistical analysis, machine learning, data engineering, and data visualization techniques to identify opportunities to improve patient outcomes, operational performance, data quality, and healthcare delivery.
The successful candidate will spend considerable time exploring complex healthcare datasets, evaluating data quality, developing predictive and descriptive models, designing experiments, and communicating analytical findings to both technical and non-technical stakeholders. A willingness to develop broad subject-matter expertise across clinical and operational domains is essential.
Success in this position requires a balance of technical expertise, analytical judgment, healthcare knowledge, communication skills, and the ability to build strong working relationships with business partners, clinical stakeholders, project teams, and other ITG teams.
GENERAL RESPONSIBILITIES
Perform exploratory, descriptive, predictive, and inferential analysis on complex clinical, operational, and business datasets.
Develop, validate, deploy, and support statistical and machine learning models that address clearly defined healthcare and business needs.
Translate clinical and operational questions into analytical hypotheses, modeling approaches, evaluation plans, and measurable outcomes.
Write efficient SQL queries and develop reusable datasets, features, and analytical pipelines using SQL, Python, R, or similar technologies.
Apply appropriate statistical methods to compare populations, treatments, interventions, and operational processes; identify trends; quantify uncertainty; and determine statistical significance.
Design and evaluate experiments, quasi-experiments, pilots, and observational studies when appropriate.
Select appropriate model evaluation metrics based on the intended clinical or business use case.
Perform model validation, error analysis, sensitivity analysis, bias assessment, and performance monitoring.
Develop interpretable analytical solutions and clearly explain model assumptions, limitations, risks, and intended use.
Partner with data engineering, product, clinical, business, and technology teams to operationalize analytical solutions.
Contribute to the development and support of production-grade data science products, services, and decision-support capabilities.
Develop high-level and detailed technical design specifications that support model development, deployment, monitoring, and troubleshooting.
Create clear documentation covering data definitions, analytical methods, model logic, assumptions, testing, limitations, and support procedures.
Identify and document data-quality issues and develop implementation strategies to improve data accuracy, completeness, consistency, and standardization.
Evaluate the usefulness, reliability, lineage, and cleanliness of data from multiple source systems.
Ensure clinical and analytical data is interpreted and presented within the appropriate clinical, operational, and business context.
Participate in requirements validation, feasibility analysis, solution design, and prioritization for data science products.
Estimate the level of effort required to deliver analytical models, experiments, data products, and supporting documentation.
Build dashboards, reports, visualizations, and analytical tools that help stakeholders understand model outputs and business performance.
Communicate analytical findings through written summaries, presentations, visualizations, and recommendations tailored to the intended audience.
Accurately communicate project status, analytical risks, model limitations, production issues, and dependencies to leadership.
Follow and promote software-development and model-development best practices, including version control, code review, reproducibility, documentation, and automated testing.
Develop and execute unit, integration, regression, performance, data-validation, and model-validation testing.
Support solutions throughout the development lifecycle, from discovery and design through deployment, monitoring, maintenance, and enhancement.
Research and become a subject-matter expert on assigned data domains, products, applications, models, source systems, and business workflows.
Monitor deployed models and analytical products for performance degradation, data drift, concept drift, unexpected outcomes, and operational issues.
Lead or participate in troubleshooting and root-cause analysis for data, model, pipeline, and production-support issues.
Resolve moderately complex to complex production issues associated with analytical applications and data products.
Identify opportunities to improve the scalability, maintainability, accuracy, reproducibility, and business value of analytical solutions.
Mentor junior data scientists, analysts, and other team members in analytical methods, coding practices, model evaluation, and healthcare-data concepts.
Provide technical guidance and peer review for analytical designs, code, statistical approaches, and model-development work.
Contribute to the development of team standards, reusable analytical frameworks, shared libraries, and data science best practices.
Work effectively both independently and as part of a multidisciplinary team.
Manage multiple priorities, establish realistic delivery dates, and consistently meet project commitments.
Build strong relationships within the department and with clinical, business, product, engineering, and project-team partners.
Take ownership of assigned responsibilities and work collaboratively to achieve team and organizational goals.
