[Hiring] Senior Data Scientist @KYROS

Role Description

We’re looking for a highly motivated data scientist to help us deliver a growing portfolio of client projects. This role is best suited for someone who thrives in a fast-paced, hands-on environment and wants to have a real impact on both client outcomes and how our work is done. The ideal candidate has strong hands-on PySpark, Python, and SQL skills, experience working with large, complex datasets, and a proven ability to clean and structure data as the foundation for analytical and modeling work.

• You’ll go beyond data engineering to design and build machine learning models and take ownership of the end-to-end data science workflow from data through insights.
• Ability to connect that technical work to the bigger picture — understanding not just how to build something, but why, and what it means for the client.
• Note: This is not an AI research or NLP/LLM engineering role. This role works primarily with structured, tabular data (e.g. member-level transactional loyalty program data), not unstructured text data.

A Day in the Life

• You start with a client's business problem — for example, what are the key drivers that impact a loyalty program’s liability or the customer behaviors that drive long-term customer lifetime value — and figure out how to turn that into a full end-to-end data science workflow.
• You work directly with the client to define data requirements and build the data pipelines to ingest and transform raw loyalty program data into clean structured datasets that are ready for analysis and modeling.
• You design, build and evaluate predictive models, making sound decisions around feature engineering, methodology, and trade-offs along the way.
• You synthesize insights from the results and translate them into a clear story that helps a non-technical client make a real business decision.
• In between, there's always ad hoc work — new client questions, one-off analyses, and the occasional problem nobody has solved before.
• There's also real opportunity to innovate: to build new solutions, design new approaches, and contribute to how our analytics platform evolves.

Qualifications

• Years of Experience: At least 5 years of professional experience in a data science, data engineering, or analytically focused role.
• Education: Bachelor’s or master’s degree in math, economics, bioinformatics, statistics, engineering, computer science, actuarial science or other quantitative field.
• Data Engineering: Demonstrated hands-on experience using Python and/or PySpark to clean, transform, and manipulate large, complex, and messy datasets.
• Skills: Strong Python and/or PySpark expertise; strong SQL expertise; ability to build and maintain production-quality analytical workflows; advanced Excel skills.
• Business Sense: Ability to connect technical work to business goals — to understand not just how to build something, but why, and what the result means for the client.
• Modeling: Familiarity with predictive modeling techniques used in an actuarial, data science, or predictive analytics focused role.
• Communication: Ability to clearly explain modeling approaches, assumptions, and results to non-technical audiences.
• Other: Strong communicator, growth mindset; ability to clearly explain modeling techniques, methodologies, assumptions, and results to both technical and non-technical audiences.

Requirements

• Actuarial background, direct experience building and analyzing P&C actuarial models end-to-end, or ACAS/FCAS qualifications are a plus.
• Demonstrated experience working with big data frameworks (e.g., Hadoop, Spark).
• Experience with dashboarding/data visualization (e.g., Plotly Dash, Power BI).

Benefits

• Retirement Plan (401k with employer match).
• Qualified Small Employer Health Reimbursement Arrangement (QSEHRA).
• Discretionary PTO.
• Fully remote.
