[Remote] Applied Scientist II

Note: The job is a remote job and is open to candidates in USA. Coalition, Inc. is the world's first Active Insurance provider focused on preventing digital risks. They are seeking an Applied Scientist II to build and enhance machine learning and GenAI models that support underwriting decisions, influencing how cyber risk is assessed and priced.

Responsibilities

• Build and advance our most sensitive and business-critical ML and GenAI models that power underwriting decisions and risk selection
• Drive and execute ML projects end-to-end: problem framing, data exploration, feature engineering, model design, prototyping, offline/online evaluation, deployment, and monitoring
• Design and implement ML pipelines for data preprocessing, feature engineering, model training, hyperparameter tuning, and model evaluation, enabling rapid and reproducible experimentation
• Apply state-of-the-art ML and GenAI workflows (e.g., gradient-boosted trees, deep learning, LLMs, prompt engineering, transfer learning) to improve underwriting accuracy, automation, and decision support
• Own model quality and robustness by defining success metrics, running ablations and diagnostics, and iterating to outperform prior baselines
• Survey and incorporate recent advances in ML/GenAI research into our core underwriting capabilities, balancing scientific rigor with practical constraints
• Collaborate closely with underwriters, product, data, and engineering partners to clarify requirements, align on tradeoffs, and ensure models integrate cleanly into production workflows
• Communicate methods and results clearly through documentation, presentations, and design reviews; share learnings and patterns that level up the broader team
• Contribute to a culture of scientific and data excellence by bringing mature empathy, best practices, and lightweight processes to experimentation, code review, and model governance

Skills

• Ph.D. or MS in a quantitative or computational field (e.g., Computer Science, Statistics, Applied Math, Electrical Engineering) or equivalent practical experience
• 5+ years of full-time experience developing and deploying ML- and data-based solutions in production
• Practical, hands-on experience with supervised and unsupervised learning methods, including model selection, regularization, and calibration
• Expertise in statistical analysis methods, especially regression analysis, statistical inference, and forecasting / time-series methods
• Strong proficiency in Python and core ML libraries (e.g., scikit-learn, XGBoost/LightGBM, PyTorch/TensorFlow) and SQL for working with large, messy datasets
• Experience with experiment design and evaluation (e.g., A/B tests, offline metrics vs. online KPIs, guardrails) and with ensuring reproducible results
• Comfortable and effective in ambiguous problem spaces; demonstrated ability to own and drive projects with minimal oversight and process
• Exceptional written and oral communication skills, with the ability to explain complex modeling choices and tradeoffs to technical and non-technical stakeholders
• Minimum 1+ year of experience in insurance underwriting modeling (pricing, risk scoring, eligibility, or related applications)
• Experience with modern GenAI techniques relevant to underwriting (e.g., using LLMs for document understanding, unstructured-to-structured extraction, or underwriter copilot workflows)
• Familiarity with model governance in regulated environments, including documentation, validation, monitoring, and change management
• Experience with ML orchestration and MLOps tools (e.g., Airflow, Prefect, MLflow, SageMaker) for managing training, deployment, and monitoring at scale
• Exposure to causal inference or uplift modeling for understanding the impact of underwriting or guideline changes
• Experience working with cyber or P&C insurance data (exposures, limits, deductibles, claims, external risk signals)

Benefits

• 100% medical, dental and vision coverage
• Flexible PTO policy
• Annual home office stipend and WeWork access
• Mental & physical health wellness programs (One Medical, Headspace, Wellhub, and more)!
• Competitive compensation and opportunity for advancement
