You will have the opportunity to deliver massive impact at a hypergrowth company backed by some of the top investors in fintech, crypto, and SaaS. In January 2026, we closed a $250M Series C led by ICONIQ, valuing Rain at $1.95B, with Sapphire Ventures, Dragonfly, Bessemer Venture Partners, Galaxy Ventures, FirstMark, Lightspeed, Norwest, and Endeavor Catalyst also participating. If you're curious, bold, and excited to help shape a borderless financial future, we'd love to talk.
Our Ethos
We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company.
About The Team
The fraud risk management team at Rain creates sophisticated, scalable risk mitigation solutions to protect our customers and deliver a low-friction experience. We achieve this by maintaining transaction and lifecycle event monitoring, building alerts to speed fraud detection and response, and creating risk rules and strategies powered by ML models. We are a pillar of the business, supporting new products and ensuring their success. Rain’s next-generation payment technology introduces new fraud vectors that require holistic, end-to-end thinking, strong data fundamentals, and fraud management savvy to combat.
What you’ll do
Architect and build scalable ML systems for fraud detection, anomaly detection, and behavioral analysis
Develop and maintain end-to-end ML pipelines: data ingestion, feature engineering, model training, deployment, and continuous monitoring
Design and implement low-latency, real-time decision systems partnering with fraud risk data scientists, integrating with transaction or behavioral data streams
Own ML infrastructure, including model versioning, automated retraining, and safe deployment strategies (e.g., shadow, rollback)
Build robust monitoring and alerting for model performance, latency, data quality, and drift
Lead experimentation on model explainability, drift detection, and adversarial robustness for fraud prevention use cases
Develop tooling and processes to improve the effectiveness and speed of the ML development lifecycle
Partner with platform teams to meet strict SLAs for availability, latency, and accuracy
Collaborate closely with talented engineers, data scientist and compliance teams across Rain
Work in a fast-paced environment on a rapidly growing product suite
Solve complex problems at the intersection of ML systems, data, and reliability
What we're looking for
5+ years of experience building ML systems in production; at least 2+ in fraud, risk, or anomaly detection domains
A degree in Computer Science, Engineering, Statistics, Applied Math, or a related technical field
Proven track record designing and maintaining ML models at scale
Advanced proficiency in Python and ML frameworks (e.g., PyTorch, TensorFlow, scikit-learn)
Strong understanding of supervised/unsupervised learning, anomaly detection, and statistical modeling
Ability to work autonomously, manage ambiguity, and collaborate closely with data scientists to translate analytical models into robust fraud prevention systems
Experience developing, validating, and productionalizing predictive real-time and offline fraud detection models using supervised and unsupervised ML techniques
Experience collaborating with cross-functional teams to prioritize, scope, and deploy MLI solutions at scale
Nice to have, but not mandatory
Domain expertise in banking, payments, or transaction monitoring
Experience with graph-based or network-level fraud detection techniques
A graduate degree in Computer Science, Engineering, Statistics, Applied Math, or a related technical field
Experience fine-tuning or adapting generative AI / large language models for pattern generation or synthetic data augmentation (in partnership with data science)
Knowledge of model governance, bias mitigation, and regulatory compliance in fraud contexts
