Full-time

5+ years building production systems, with 3+ years focused on fraud, risk, or trust and safety.

Base salary range: $185,000 - $220,000

Note:

This range reflects base salary only. Final level, team assignment, and compensation are determined during the interview process based on experience and fit.

• Stock options are part of every full-time offer, granted on top of the base salary range above. We want everyone here to be a genuine stakeholder in what we're building.

• We conduct two performance reviews annually. The first addresses performance ratings, bonuses, and promotions. The second encompasses these elements along with salary adjustments reflecting inflation and market conditions.

We are hiring our first dedicated Anti-Fraud Engineer.

Crossmint moves billions across remittances, payroll, on/offramps, card rails, and agent-initiated payments. Every one of those flows carries a fraud surface, and today the controls live inside each product. This role builds the decisioning layer that all of them use, and owns the numbers it produces.

The role has a loss line attached to it. You will know what fraud costs us, which controls moved that number, and which good customers we blocked on the way. If you want a job where the impact is arguable, this is not it.

You will report to the Engineering Manager for Identity, Compliance & Risk and work day to day with our Risk Operations analysts, Compliance, Legal, Security, and the product teams whose flows you protect. Crossmint operates under MiCA, DORA, SOC 2, and PSD2, so your controls carry both a commercial and a licensing consequence.

This is a hands-on role. You will write the code, read the data, and take the pager.

Own fraud decisioning

• Build and own the services that score and decide onboarding attempts, stablecoin transfers, on/offramp orders, and card transactions.

• Turn analyst judgment into production rules and models, with clear thresholds, versioning, backtesting, and a fast path to roll back.

• Build the signals those decisions depend on: device, behavior, velocity, counter party, and graph relationships across clients and wallets.

• Measure every decision. Own catch rate, false-positive rate, and fraud loss per product line, and publish them without being asked.

Detect and respond

• Build detection for account takeover, mule networks, first-party fraud, synthetic identities, refund and promo abuse, and agent-initiated payment abuse.

• Cut the time…
