Senior ML / AWS Engineer - Pipeline Hardening, Governance & Integrations

You’ll own the parts of the systems that make them trustworthy and connected: hardened batch pipelines, model governance and lineage, and the external data integrations the systems depend on. In a regulated setting this is not back-office work - the ability to show exactly how a model was trained, on what data, and why it flagged an account is a core requirement, and this seat owns it. The second seat arrives as the DeFi integration surface materializes: attribution vendors, chain-data providers, and the international exchange’s market-metadata feeds.

What you’ll do:

• Hardening and maintaining the batch pipelines and feature infrastructure the models run on. This is proven, high-value work: turning multi-hour hangs into completing jobs took real data-skew engineering (pre-aggregation, windowing, connection-pool and capacity tuning), and that discipline needs a permanent owner.
• Model governance: versioning, lineage, reproducibility, and audit-ready records of how every model and flag was produced. We already stamp model-package version, scoring-run ID, and feature-snapshot time on every score, gate registration behind quality checks, and run a feature-contract check that stops a run rather than silently scoring on drifted features. This seat extends and defends that - across both estates.
• The external integrations that feed the systems - surveillance-vendor feeds (Eventus, in first-wave AWS ingestion), screening providers (PEP/sanctions), KYC/identity sources (a live feed plus historical), market/event data, and, as the DeFi build ramps, blockchain-attribution vendors and chain-data providers.
• The MLOps tooling that keeps deployments consistent and reversible.
• Keeping the systems audit-ready as they grow, in partnership with data science and compliance.

• 5+ years of experience in data / ML pipeline engineering
• Hands-on MLOps: model registries, versioning, lineage, and reproducible deployment
• Experience building and maintaining third-party API and data integrations
• Production AWS experience
• Comfort working to governance and audit requirements; regulated-domain experience a plus
