What this job asks for AI summary
A backend engineering role focused on building and maintaining compliance and financial-crimes infrastructure for a prediction market platform. Day-to-day work involves designing detection and monitoring systems for AML/BSA, KYC, and sanctions obligations, integrating trade-surveillance platforms, structuring audit-grade data pipelines, and developing real-time transaction-monitoring tools — all in close collaboration with Compliance, Risk, and Legal teams. Best suited to engineers with a fintech or crypto compliance-technology background.

Why we read it this way (7)
No work location is specified in the posting; the CBSA field is left blank. The role may be remote or NYC-based (Polymarket's home), but the JD does not state either explicitly.
The title is simply 'backend engineer' with no seniority modifier, but the required scope — owning compliance/AML/KYC systems end-to-end, partnering directly with Legal/Risk/Compliance, and a cited benchmark of Coinbase Risk Engineering / Robinhood Financial Crimes — clearly targets a Senior-level candidate.
Eventus and Palantir are listed as illustrative examples of trade-surveillance/case-management platforms; they are captured as alternatives on that skill rather than as separate hard gates.
Real-time risk decisioning / transaction monitoring is explicitly marked as a 'Plus' (nice-to-have) in the posting.
The alt SOC 15-1299 is noted because this role sits at the intersection of backend software development and compliance/financial-crimes technology — a specialized niche that BLS does not have a dedicated code for; 15-1252 is the best primary fit given the emphasis on building and engineering systems.
Compensation is described only as 'competitive salary & equity' with no figures given.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): AML/BSA compliance systems, audit-grade data pipelines, real-time transaction monitoring.
