Senior Integration Engineer

As a Senior Integration Engineer, you will design, build, secure, and operate enterprise‑grade APIs that integrate cloud platforms with on‑premise banking application suites. The role focuses on developing reliable and scalable integration services, enabling secure data exchange across core banking, payments, fraud, risk, CRM, and digital platforms, while meeting stringent regulatory, availability, and security requirements. You will work closely with solution architects, platform engineers, security teams, and business stakeholders to deliver API products aligned to bank integration patterns, including synchronous REST services and event‑driven integrations.

Direct line reporting: Head of Architecture and Core Banking – Europe.

• API Design & Delivery: Design and implement RESTful APIs and integration services connecting cloud services to on‑prem banking systems; create reusable API patterns for common banking capabilities (customer, accounts, payments, transactions, entitlements); define and maintain API contracts (OpenAPI/Swagger), versioning strategies, and backward compatibility; deliver APIs that meet performance, latency, availability, and resiliency expectations (timeouts, retries, circuit breakers).
• Security, Compliance & Controls: Implement strong API security controls (OAuth2/OIDC, mTLS, JWT validation, request signing, API gateway policies, rate limiting); apply secure coding practices and align solutions with bank security standards, audit requirements, and regulatory expectations (least privilege, encryption in transit/at rest); collaborate with security to support threat modeling, pen test remediation, and secure configuration management.
• Cloud–On‑Prem Connectivity & Integration: Build and operate integration flows using enterprise tooling (API gateway, service mesh, ESB/iPaaS, message brokers); implement hybrid connectivity patterns such as VPN/ExpressRoute/Direct Connect equivalents, private endpoints, network segmentation, and secure routing; integrate with on‑prem technologies (MQ, legacy services, SOAP where required, databases, batch systems) and modern cloud services.
• Observability & Operations: Implement observability (structured logging, distributed tracing, metrics, dashboards, alerting); support production deployments and incident triage; conduct root cause analysis and introduce reliability improvements; automate CI/CD pipelines and Infrastructure/Configuration as Code where applicable.
• Engineering Excellence: Write clean, testable code (unit/integration/contract tests); participate in code reviews, technical design reviews, and architecture governance; document API products and integration runbooks for support and operational readiness.
• Knowledge & Experience: 5+ years developing APIs/integration services in regulated enterprise environments (banking/financial services preferred); BA/MBA in IT or relevant experience; proven experience building hybrid integrations (cloud to on‑prem) and secure data exchange; strong hands‑on API design, implementation, and lifecycle management.
• Technical Skills: Proficiency in Java (Spring Boot), .NET, Node.js, or Python; experience with API gateways (Apigee, Kong, Azure API Management, AWS API Gateway, Mulesoft, etc.); messaging/eventing platforms (Kafka, MQ, RabbitMQ, Azure Service Bus); containerization/orchestration (Docker, Kubernetes/OpenShift); understanding of integration patterns (sync/async, pub/sub, idempotency, retries, backpressure, saga/compensation, data consistency); data formats (JSON, XML, Avro) and schema evolution.
• Security & Quality: Experience implementing OAuth2/OIDC, mTLS, certificate management, secrets management (e.g., Vault, Key Vault, Secrets Manager); SDLC controls (SAST/DAST, dependency scanning, secure CI pipelines); test automation (unit, integration, contract testing such as Pact).
• Personal Attributes: Highly organized, proactive, detail‑oriented; able to operate at pace; comfortable with ambiguity; resilient, calm under pressure; collaborative and inclusive leadership; banking domain knowledge (payments, card processing, AML/KYC, customer onboarding); familiarity with service mesh (Istio/Linkerd) and zero trust patterns; knowledge of TOGAF, enterprise integration architecture, or API product management; awareness of GDPR data privacy and retention requirements.
• Key Competencies: Communications & Relationships; Agility and Innovation; Collaboration; Drive for Results; Ethics and Trust; Inclusion; Customer Centricity; Commercial Judgement; Managing Programs.

• 3 Conduct Standards & Rules: Act with professionalism and integrity; act with due skill and diligence; cooperate with the Central Bank of Ireland and regulators; disclose information as required.
• Location expectations: Requires working from a U.S. Bank location three (3) or more days per week.
• Accessibility: We are committed to an inclusive and accessible recruitment experience. If you need adjustments, contact your recruiter for guidance.
• Total Rewards: U.S. Bank offers competitive compensation, incentives where eligible, inclusive benefits, development opportunities, and recognition programs. Further details provided upon application.
