About the role
- The work now spans two detection stacks on different grains: the account-grain L1-L3 stack on the US exchange and the wallet/cluster-grain D1-D3 stack of the DeFi Integrity Engine.
- The two seats split by venue focus while operating as one modeling practice: shared methodology (robust statistics on heavy-tailed data, calibration discipline, the labeling loop), different substrates.
- This is a hands-on modeling role with a lot of room to shape the detection architecture over the life of the program.
Responsibilities
- Design and refine features on large-scale financial time-series and on-chain data, with an emphasis on signals that hold up under noisy, heavy-tailed conditions Develop and improve anomaly-detection models across both supervised and unsupervised approaches Evolve the model architectures as labels accumulate - from simpler classifiers toward multi-class, per-scenario, and ensemble designs; on the DeFi side, activate the supervised layer from a standing start as the first disposition labels arrive Improve detector calibration so scores are trustworthy and comparable across market types and venues Partner with the validation and analyst teams on the labeling pipelines that supply the models' training signal
Nice to have
- on-chain data familiarity a plus
