It employs a ground-breaking focus with development responsibilities for customer-facing capabilities that deepen and expand digital engagement, as well as core technical capabilities that cut across business lines and customer segments. American Express Travel & Lifestyle Technology builds platforms that power premium travel experiences for millions of Card Members. We partner with industry-leading third parties to deliver booking, inventory, and fulfillment capabilities at scale, with high expectations for reliability, performance, and customer experience. We are seeking a Staff Software Engineer to provide technical ownership and leadership for these critical third-party travel platforms.

Requirements

• 10+ years of experience designing, building, and operating large-scale, distributed systems in production.
• Demonstrated ownership of mission-critical third-party or SaaS integrations, including architecture, reliability, and lifecycle management.
• Deep expertise in API design and integration patterns, including synchronous and asynchronous workflows, versioning, and backward compatibility.
• Strong understanding of distributed systems fundamentals, including fault tolerance, latency tradeoffs, consistency models, and failure isolation.
• Hands-on experience designing for resilience and high availability, including retries, circuit breakers, graceful degradation, and multi-vendor strategies.
• Experience implementing contract testing, schema governance, and pre-production validation for external integrations.
• Strong data engineering fundamentals, including data modeling, reconciliation, data quality controls, and lineage across system boundaries.
• Experience partnering with SRE and platform teams to improve observability and operational maturity.
• Solid understanding of integration security architecture, including authentication, authorization, secure networking, and sensitive data protection.
• Proven ability to translate technical risk into business impact and influence decisions across engineering, product, and external partners.

Nice To Haves

• Experience in travel, payments, commerce, or other real-time transactional domains.
• Prior responsibility for vendor technical relationships, including roadmap influence and participation in renewal or replacement decisions.
• Experience defining and enforcing integration standards across multiple teams or platforms.
• Strong cloud-native architecture experience (AWS or equivalent), including networking and observability tooling.
• Experience evaluating vendors, leading build vs buy decisions, or executing platform migrations.
• Familiarity with modern API gateways, event-driven architectures, and service-to-service communication patterns.
• Experience supporting analytics or AI use cases that depend on third-party data, with an emphasis on traceability and compliance.

Responsibilities

• Act as the single technical owner for all critical third-party travel platforms, including booking, inventory, and fulfillment providers.
• Define and maintain integration architecture, standards, and patterns that support reliability, scalability, observability, and vendor isolation.
• Serve as the primary technical counterpart to vendor engineering leadership, including directors and CTOs.
• Push vendors on API design, performance, reliability, security posture, network architecture, and operational readiness.
• Influence vendor product roadmaps and provide technical input into vendor selection, renewal, and replacement decisions.
• Establish API contract governance, versioning standards, and automated contract testing to prevent breaking changes.
• Partner with SRE to address systemic integration risks and ensure durable remediation of recurring issues without owning day-to-day support.
• Drive resilience practices including graceful degradation, dependency isolation, and multi-vendor fallback strategies.
• Define data quality, consistency, and lineage expectations for third-party data flows in partnership with Data and Product teams.
• Support contract negotiations with clear technical acceptance criteria, SLAs, and non-functional requirements.
• Collaborate with enterprise architecture and internal platform staff engineers to align with portfolio and enterprise strategy.
• Mentor engineers across teams on integration design, distributed systems tradeoffs, and vendor constraints.
• Work closely with product and business architecture to surface technical risks early and shape roadmap decisions.
