About The Opportunity Good compliance analytics depends entirely on good data infrastructure. At a global crypto exchange, that infrastructure has to handle on-chain transaction data, fiat flows, KYC and KYB records, and behavioural signals across multiple jurisdictions, all in a form that data scientists and analysts can actually use. This role exists to build and own that foundation, and the quality of what gets built here directly shapes what the compliance function is capable of detecting. You will work closely with data scientists, ML engineers, analytics engineers, and compliance specialists as a core part of the team that delivers compliance intelligence at scale. The infrastructure you build is not internal plumbing; it is what enables detection models to run, self-serve analytics to function, and regulatory responses to be grounded in reliable, traceable data. AI-assisted engineering is how this team works. We use LLM tooling to accelerate pipeline development, automate documentation, improve code quality, and move faster on complex data problems. We are looking for a data engineer who already works this way and can bring that practice into a compliance data environment where reliability and auditability are non-negotiable alongside speed. What You’ll Be Doing - Design, build, and maintain scalable data pipelines that ingest, transform, and deliver data for compliance analytics use cases including AML transaction monitoring, KYC/KYB, sanctions screening, and SAR reporting. - Assess and improve existing data infrastructure: identify pipeline gaps, lineage issues, and data quality problems that silently degrade model and analytics output, and work through them systematically. - Build and maintain compliance-specific data marts and semantic layers that allow data scientists and analysts to work independently, reducing the volume of ad-hoc data requests and increasing the team's overall throughput. - Partner with data scientists and ML engineers to productionise feature pipelines, maintain data freshness, and build the infrastructure that keeps compliance ML models running reliably in production. - Apply AI-assisted development as standard practice: using LLM tooling to write and review pipeline code, automate data quality checks, generate documentation, and accelerate debugging. The expectation is that you bring this fluency with you and use it to raise the quality and pace of your work. - Implement data quality monitoring, pipeline health checks, and alerting that surfaces data integrity issues before they affect compliance decisions or model outputs. - Work with compliance and legal teams to understand regulatory requirements around data retention, access control, and auditability, and build the controls that meet those requirements in practice. - Support regulatory lookbacks and audit responses by ensuring historical data is retrievable, lineage is documented, and the evidence base the compliance team needs can be assembled accurately and quickly. What We Look For In You - 8+ years in data engineering or a closely related role, with meaningful experience in financial services, fintech, or a compliance-adjacent environment. We welcome candidates across seniority levels; scope and responsibilities will be calibrated to your experience. - Strong Python and SQL, with hands-on experience in distributed computing frameworks such as Spark, Hadoop, or Databricks. - Solid experience with cloud and big data platforms including Alibaba MaxCompute, Google BigQuery, AWS Redshift, or equivalent, and a track record of building production-grade pipelines where reliability and data quality are treated as requirements rather than afterthoughts. - Hands-on fluency with AI-assisted engineering. You use LLM coding tools regularly, have applied them to real data engineering work, and have a practical view on where they improve output quality and where they nee
