Staff Engineer

RemoteFull TimeIndividual Contributor+8 Years of Experience Staff Engineer, Money, Risk & Payment AncillariesAbout The RoleYuno is looking for a Staff Engineer to be the senior technical leader for Money, Risk & Payment Ancillaries — the business unit that protects money and manages risk across every transaction on the platform. Spanning risk, fraud, scams, money operations, reconciliations, and chargebacks, this is the domain where financial correctness, real-time decisioning, and trust are non-negotiable. You'll architect the foundational systems behind these capabilities and raise the technical bar for the teams that build them. This is a hands?on leadership role in a zero?tolerance?for?failure environment — every cent must be accounted for, and every risk decision must be fast, accurate, and auditable. You'll design and build bank?grade, resilient systems, champion a "You Build It, You Run It" culture, and turn the hardest problems in money movement and risk into elegant, maintainable architecture.
What This Unit OwnsRisk & Risk Operationsreal?time risk decisioning and the operational tooling that powers itFrauddetecting and preventing fraudulent transactions across the networkScamsprotecting users from authorized push payment (APP) scams and social?engineering attacksMoney Operationsthe movement and settlement of funds across the platformReconciliationsmatching transactions, settlements, and ledgers to guarantee financial accuracyChargebacksmanaging disputes, representment, and the full chargeback lifecycleHow AI Shows Up in This RoleThe systems you build power Yuno's AI?driven risk, fraud, and scam engines — the models and pipelines that evaluate every transaction, plus the agents that automate reconciliation and dispute workflows at scale AI is our default execution layer: you're expected to use AI?assisted tooling fluently across design, implementation, testing, and review, and to shape how the unit adopts itYour Contribution Will BeCross?domain architecture and technical leadership — own the architecture across risk, fraud, scams, money operations, reconciliations, and chargebacks; set the technical direction with versioned APIs and event?driven design, and raise the bar for the teams Real?time risk and fraud systems — architect the low?latency systems that score transactions for risk and fraud and act on them before or at authorization Money movement and financial correctness — build money operations and reconciliation systems with idempotency, exactly?once semantics, and auditable ledgers, so every cent is accounted for Scams and disputes — design the platforms behind scam prevention and the chargeback and dispute lifecycle, aligned with card?network rules and regulatory requirements Bank?grade, resilient systems — design highly available, compliant capabilities engineered for a zero?tolerance?for?failure environment, where feature velocity never compromises reliability You Build It, You Run It — champion a YBIYRI culture: your teams design for multi?tenancy, elastic scaling, and automated observability, and own their microservices in production Mentorship and cross?functional collaboration — mentor engineers and partner with Product, Data/ML, Compliance, and Staff Engineers across domains to deliver complex, cross?team workWhat Success Looks LikeWithin your first 6–12 months, you've led the architecture of at least one core capability across the unit (risk decisioning, fraud or scam prevention, money operations, reconciliation, or chargebacks), your teams own their services in production under a YBIYRI model, and you're the technical voice Yuno trusts on financial correctness and real?time risk.
