About the Role

Lead a major Financial Crime Protection intelligence solution, guiding complete products across data, backend services, APIs, AI, and review experiences. Set solution-level directions while staying close to design, code, testing, and production support. The systems will support authorized decisions without making fraud, AML, employee, customer, or operational decisions.

Responsibilities

Lead a major Financial Crime Protection intelligence solution from intent through design, build, verification, release, and operation.
Bring Financial Crime Protection domain-SME thinking into engineering decisions, translating complex fraud, AML, and protection needs into safe, practical production outcomes.
Set clear boundaries between signals, investigation, human decisions, and actions in other systems.
Create traceable contracts across source data, events, entities, facts, signals, models, agents, reviews, and downstream systems.
Ensure missing, stale, denied, incomplete, and unavailable information is reported honestly.
Enforce agent controls outside the model, with approved bounded tools, access controls, and safe action boundaries.
Protect sensitive and Highly Protected data through least privilege, minimization, pseudonymization, and controlled disclosure.
Lead versioned and reversible releases for data contracts, models, embeddings, APIs, and workflows, with tested rollback and recovery.
Mentor engineers and turn specialist delivery lessons into reusable patterns.

Requirements

Deep Financial Crime Protection domain-SME experience, with strong practical knowledge of fraud, AML, investigations, intelligence workflows, controls, and human decision-making in a complex regulated environment.
Expert full-stack engineering across backend services, APIs, data stores, and modern web applications.
Strong API, event, dataflow, and service-boundary design, including identity, entitlements, state, audit, and recovery.
Strong data, graph, and investigation engineering covering lineage, time, quality, entity resolution, bounded traversal, and purpose-based access.
Strong AI service engineering across ML signals, LLMs, RAG, agents, prompt and model evaluation, tool controls, versioning, monitoring, and fallback.
Strong engineering for accessible human review, including evidence, provenance, uncertainty, approval, disposition, and recovery.
Sound judgement about when rules, SQL, conventional ML, graphs, or generative AI provide the simplest safe solution.
