About the Opportunity

First Help Financial, recently voted as a “Great Place to Work” for the fifth year in a row is seeking a Machine Learning Engineer to join our highly skilled and innovative team. First Help Financial is embarking on a new growth phase involving multiple game‑changing projects.

What you will do

• Design, develop, validate, and continuously enhance end‑to‑end risk models and scorecards across the credit lifecycle, including Originations, Pricing, Loss Forecasting, Servicing, and Collections.
• Partner closely with Risk, Finance, Product, and Operations teams to translate business problems into analytical solutions that drive measurable outcomes.
• Evaluate and integrate new data sources, features, and modeling approaches, assessing their incremental value, robustness, and impact on risk and profitability.
• Lead what‑if, stress testing, and scenario analyses to support strategic initiatives, new programs, and policy changes.
• Ensure models are interpretable, stable, and production‑ready, balancing predictive power with regulatory and operational constraints.
• Own the ongoing monitoring and performance tracking of models, identifying degradation, bias, or drift and proactively proposing improvements.
• Stay current on regulatory expectations and industry best practices in credit risk modeling, particularly within the auto finance space, and incorporate them into modeling standards and documentation.

What you bring

• Bachelor’s degree in Statistics, Mathematics, Engineering, Computer Science, Physics, or a related quantitative field (Master’s or PhD is a plus).
• 5+ years of hands‑on experience building and deploying predictive models in a production environment, preferably within credit risk, lending, or financial services.
• Proven experience developing scorecards and statistical models using techniques such as logistic and linear regression, tree‑based methods, ensemble models, time series, survival analysis, clustering, and/or machine learning methods.
• Strong proficiency in Python and SQL, with the ability to manipulate, analyze, and extract insights from large, complex, and imperfect datasets.
• Solid understanding of the full model lifecycle — from data exploration and feature engineering to validation, monitoring, and retraining.
• Ability to communicate complex analytical findings clearly and confidently to both technical and non‑technical stakeholders.
• A pragmatic mindset: you know when to optimize for accuracy, explainability, speed, or compliance — and how to make trade‑offs responsibly.
• Great Perks – We offer generous salaries, social activities, monthly lunches, and a robust employee recognition and talent development program to enhance your career with us.
• Culture – We are believers in maintaining a healthy work‑life balance. While we work hard and care deeply about our customers and partners, we want you to have room for your family, friends, and yourself.
