Data Scientist

Description:

Nayax is a global fintech company (NASDAQ; TASE: NYAX) and a leading provider of cashless payment, consumer engagement, and business management solutions for the unattended retail sectors.

We are currently seeking a a hands-on Data Scientist to esearch and analyze multiple financial datasets (payments, loans/credit, and adjacent instruments) and turn findings into revenue-generating insights. You’ll have wide autonomy to explore data yet stay tightly aligned to business outcomes helping us shape pricing, new products, underwriting/credit strategies, and operational efficiency.

Beyond analysis, you’ll lay the foundation for our data practice: lightweight processes, governance, and working methods that scale globally across the USA, EMEA and APAC. The ideal candidate brings a startup mentality, is fluent in fintech models (neobanks, cloud-native stacks, digital banking), and is comfortable coding, querying across heterogeneous databases (including federation), and leveraging modern AI tooling, preferably on AWS.

Key Responsibilities:

• Own the research agenda across internal and external financial databases; discover signals that drive new revenue and margin expansion.
• Translate ambiguous business questions into crisp analytical plans, metrics, and experiments.
• Query and join data across multiple systems (SQL/NoSQL, data warehouses, APIs); use federated query engines (e.g., Athena/Presto/Trino) where appropriate.
• Build repeatable analysis assets (SQL models, notebooks, lightweight pipelines) and executive-ready artifacts (dashboards, briefs).
• Partner with Product, Finance, Risk/Credit, Operations and Sales to, set success metrics, and track impact.
• Prototype and apply AI/ML where it matters (e.g., segmentation, propensity, anomaly/fraud signals, pricing experiments) using AWS services (e.g., SageMaker/Bedrock) or equivalent.
• Establish pragmatic data governance: source cataloging, documentation, versioning, code review standards, and data quality checks.
• Champion best practices in privacy/security and compliance in a payments/credit context.

• 4+ years in analytics/data science/data engineering or quant research roles, with fintech/payments/credit exposure (how payment flows, chargebacks, interchange, and basic credit/underwriting work) Preferably in a fintech company or other startup organization focused on B2B financial solutions
• Strong SQL (window functions, performance tuning) and Python for analysis/ETL (NumPy, pandas/pyarrow; basic PySpark a plus).
• Comfort with AWS data stack (S3, Glue/Athena, Redshift or Snowflake-on-AWS; SageMaker/Bedrock familiarity preferred).
• Experience querying across heterogeneous databases and/or federated queries; able to design sane data models and joins across messy sources.
• Proven track record turning analysis into business outcomes (pricing, product, revenue ops, credit/risk insights).
• Data visualization competency (qliksense, Power BI) and clear writing/presentation for executives.
• Startup mindset: self-directed, bias to action, comfortable with ambiguity; willing to build processes while shipping work.
• Solid engineering hygiene: Git, reproducible notebooks/pipelines, documentation, and basic testing.
• Working knowledge of data governance, privacy, and controls expected in financial services.

What Makes This Role Exciting

• Work with diverse financial datasets and uncover insights that directly impact revenue, pricing, and credit strategies.
• Shape the company’s global data culture, governance, and best practices across USA, EMEA, and APAC.
• Leverage cutting-edge cloud-native architectures, AI/ML tools, and federated data systems to solve real-world fintech problems.
• Collaborate closely with Product, Risk, Sales, and Finance teams, ensuring your analyses drive tangible business outcomes.
• Enjoy autonomy and a startup-like environment, where your creativity, initiative, and solutions have a visible impact.
• Build foundational processes, pipelines, and analytical assets that scale across the organization and set new standards.
