Effect (Effect-TS) is an open-source, production-grade TypeScript ecosystem and library designed to build robust, highly scalable, and predictable software. Originally inspired by effect systems from other functional programming languages (such as ZIO in Scala), Effect provides a unified meta-language for TypeScript that addresses core native limitations in error management, asynchronous concurrency, and dependency injection.

About us

Satispay began by rethinking the simple act of a payment to remove the friction from our daily routines. But we didn't stop there. Today, we are building a complete financial platform designed to empower people and concretely improve their lives.

By giving our 6 million users a clear, open path to pay, save, and invest, we are evolving into the definitive destination for every financial need.

What you'll be doing

As our Fraud Data Analyst, you'll be the person who secures the future of digital payments by architecting sophisticated real-time defense strategies.

Here's what your day-to-day will look like:

  • Architect Real-Time Strategies - You will be responsible for our real-time decisioning engine, designing and deploying logic that combines ML scores with velocity features to make millisecond decisions.

  • Precision Rule Development - Translate complex fraud patterns into high-performing rules, optimizing the balance between False Positive Rates (FPR) and Gross Fraud Loss.

  • Deconstruct Payment Fraud - Proactively hunt for emerging schemes (ATO, social engineering) and turn these insights into end-to-end mitigation strategies.

  • Optimize the Decisioning Stack - Partner with Product and Engineering to define analytical requirements for new features and third-party data signals.

  • Calibrate ML & Heuristics - Work with Data Science to operationalize machine learning models, determining how to best "wrap" model scores with heuristic rules.

  • Champion Frictionless UX - Analyze security measures to identify unnecessary hurdles, designing dynamic friction strategies for a seamless user experience.

  • Strategic Performance Reporting - Monitor rule efficacy and portfolio health, presenting data-driven recommendations to senior leadership to evolve our risk appetite.

Expect challenges, collaboration, and the freedom to bring your ideas to life in a fast-moving and supportive environment. Things change quickly here, so be ready to adapt, take initiative, and shape your role as we grow.

Who we're looking for

We need a problem-solver who loves teamwork and gets things done. If you're curious and ready for real ownership, you'll fit in! Does this sound like you?

  • Experience - You have between 3 and 7 years of professional experience, specifically within the risk, payments, or credit sectors.

  • Technical Proficiency - You are highly skilled in SQL and Python for data analysis and strategy development.

  • Domain Expertise - You have a solid understanding of payment fraud dynamics and experience working with real-time decisioning environments.

  • Communication - You possess excellent communication skills and are fluent in English.

  • Nice to Have - Experience with Machine Learning, Data Science, PySpark, or GraphQL knowledge is a significant plus.
