As a Data Scientist at SentiLink, you will be responsible for developing and maintaining our core product: models that identify fraudsters and synthetic identities. You will also interface with teams across the company to develop new products, provide analysis to support different business needs (product management, business development, risk operations), and help to productionalize insights and ensure their scalability.

This is a full-stack data science role, involving model development, analysis, and writing tested, production-quality code. Candidates should have previous data science work experience and be interested in a fast-moving company where deep domain understanding drives development.

    • Work with product and engineering teams to develop new identity verification products
    • Write production-ready code that can be relied on for real-time decision making by our partners
    • Perform analyses that will inform data acquisition, product development, risk operations priorities, and sales efforts
    • Work with engineering to access necessary data, maintain data quality, and support data access for other teams
    • Dig deep to identify new trends in fraud and update our models to capture them

Work Experience

    • A graduate degree in a technical field and 1+ years relevant work experience OR 3+ years relevant work experience (e.g. data scientist, machine learning engineer)

    • Awesome co-workers and cool team activities (go-karting, scuba diving, blacksmithing, etc.)
    • Insurance (medical/dental/vision) for you and your dependents
