About ArborKnot:

ArborKnot is a dynamic global financial group specializing in pricing & managing distressed consumer receivables in an amicable way. With $765 million AUM (as at end May 25’), our mission is to alleviate the burden of debt on individuals, enabling them to lead better lives through innovative & data driven recovery practices.

We’re challenging traditional market practices. Our innovative approach fosters a dynamic marketplace for our clients and consumers.

With offices in Sydney, Berlin, New York, and an innovation lab in Tel Aviv, Israel, ArborKnot offers a unique opportunity to be part of a fast-growing, multicultural team dedicated to driving positive industry and social change.

As a Machine Learning engineer at ArborKnot, you will be at the forefront of transforming the debt recovery landscape through data. You’ll turn complex behavioral signals into scalable, reliable systems that drive real-world financial decisions, working with highly imbalanced datasets to predict repayment likelihood, detect anomalies, and optimize recovery strategies. 

Your day-to-day will involve more than just model deployment - you’ll help shape our model lifecycle end-to-end, from experimentation and explainability through pipelines and monitoring. You'll get the chance to dig deep into our pricing and recovery strategy , surface the most meaningful drivers of payments behavior, and contribute to research and feature engineering. You’ll take ownership of building systems that allow us to scale with confidence, making our pricing, recovery, and risk strategies both cutting-edge and production-ready.
