About the role
Sardine sits on one of the richest behavioral datasets in fraud and risk: device intelligence, behavior biometrics, session telemetry, payment events, and consortium signals that we leverage to fight fraud across hundreds of fintechs and banks. We are looking for an applied research scientist that brings their expertise in deep learning and foundation models to take this to the next level.
We are looking for an experienced ML applied scientist that can combine foundation model expertise with rich non-text sequential data to come up with practical, state-of-the-art fraud detection solutions. You will have an opportunity to scope and drive the next generation of fraud foundation models at Sardine, and drive industry-wide adoption.
What you'll be doing
Identify and scope opportunities, design rigorous experiments, and execute on the roadmap for foundation model research and development.
Own the evaluation bar for foundation model performance: offline benchmarks, time- and entity-aware holdouts, calibration, drift and degradation monitoring, and honest head-to-head comparisons against strong classical baselines.
Take models the full distance from data prep and tokenization through pretraining, fine-tuning, distillation, quantization, and deployment behind a real-time inference path with tight latency budgets.
Partner with Engineering on training infrastructure, GPU efficiency, feature and embedding stores, and serving at production scale
Work directly with client-facing teams and customers to turn model capabilities and limits into decisions their risk teams can act on.
Partner with Legal, Compliance, and customer model risk teams to build the explainability, documentation, and governance our bank and fintech customers need to satisfy their own regulators.
What you'll need
4+ years in applied machine learning, quantitative modeling, or ML engineering including at least one foundation model you pre trained or substantially adapted and put in front of real traffic
Hands-on self-supervised pre training experience, plus practical fine-tuning and adaptation
Production experience with model serving, versioning, monitoring, and rollback
Ability to self-manage and drive ambiguous applied research projects with clear communication with partner teams across data science, engineering, product, marketing and external partners
Strong Python, strong SQL, and comfort preparing very large datasets
Nice to haves
Background in fraud, AML, payments, credit, or adversarial machine learning
Experience building and evaluating LLM-based agents in production
Publications, released models, or open source contributions in representation learning or sequence modeling
Experience with model risk management and documentation in a regulated financial environment
