Our Purpose Mastercard powers economies and empowers people in 200+ countries and territories worldwide. Together with our customers, we’re helping build a sustainable economy where everyone can prosper. We support a wide range of digital payments choices, making transactions secure, simple, smart and accessible. Our technology and innovation, partnerships and networks combine to deliver a unique set of products and services that help people, businesses and governments realize their greatest potential. Title and Summary Principal Software Engineer - Treasury Services The Opportunity We’re seeking a Principal Software Engineer who combines hands-on technical depth with cross-organizational influence. You’ll be the technical SME for modernizing data flows across the treasury platforms, leading design and delivery of event-driven microservices and enabling expanded use of our Treasury Management System (TMS) to elevate automation, reliability, and real-time decision making. This role is ideal for a principal-level engineer who is equally comfortable writing production code, setting architectural guardrails, partnering with Finance/Treasury stakeholders, and aligning multiple engineering teams around a cohesive platform strategy. What You’ll Do • Architect and implement data integration pipelines with Mastercard’s Treasury Management System (TMS) including: o Bank connectivity (APIs, Swift, host-to-host), statement ingestion, payment/settlement instructions, reconciliation. o Market data ingestion (rates, curves, credit spreads) and valuation workflows. o Trade/hedge lifecycle (creation, amendment, valuation, accounting, P&L/GL posting). o Extensibility: custom adapters, data pipelines, reference data mastering, error handling/observability patterns. • Lead end-to-end technical delivery for critical treasury capabilities (e.g., cash positioning, liquidity forecasting, hedge lifecycle management, deal capture/valuation, settlements, GL posting flows). • Drive platform hardening: throughput, latency, operational resilience, and observability (metrics, logs, traces, SLOs). • Define and evolve the integration architecture within Treasury Services: domain-driven, event-driven, microservices-based, secure-by-default, and API enabled. • Establish eventing patterns and schemas (Kafka topics, contracts, idempotency, exactly-once semantics where applicable) across teams; drive adoption of consumer-first and backward-compatible contracts. • Serve as a trusted technical advisor for senior engineering leaders, Finance/Treasury product owners, InfoSec, Risk, and Compliance. • Lead architecture reviews, RFCs, and design forums; mentor Staff/Senior Engineers; uplift engineering standards (testing, code quality, performance). • Aligning multiple teams on platform roadmaps, migration/modernization plans, and incremental delivery that de-risks change. • Build for HA/DR, regional failover, runbooks, chaos testing, and fault injection. • Ensure compliance with internal controls and relevant financial reporting standards in integration patterns and data flows. Basic Qualifications • 10+ years in professional software engineering with 7+ years building Java services at scale. • Expert in Java, Spring / Spring Boot, Hibernate/JPA, REST/APIs, Kafka (or similar event streaming), and microservices architecture. • Proven track record integrating and extending a vendor TMS, preferably ION Reval (or similar: Kyriba, FIS Quantum, GTreasury, SAP TRM), including building robust adapters and data pipelines. • Demonstrated cross-organizational influence: leading architecture decisions, aligning multiple teams, mentoring senior engineers, and driving platform-wide standards. • Solid grasp of data modeling (relational & event schemas), transactional integrity, idempotency, eventual consistency, and distributed systems patterns. Preferred Qualifications • Direct experience with ION Reval or similar TMS systems to enhance corporate treasury products and services (e.g., trade import/export, valuation, accounting, payment workflows, statement ingestion, market data integration). • Experience with financial data and treasury domain concepts: cash positioning, liquidity optimization, FX/IR hedging, intercompany loans, netting, settlements, GL/subledger integration. • Knowledge of data platforms (e.g., Kafka Streams/Flink/Spark), schema management (Avro/Protobuf/JSON Schema), and streaming ETL patterns. • Familiarity with security & compliance in financial systems (audit trails, SOX/internal controls, data retention, PII handling). Tech Stack • Languages/Frameworks: Java 17+, Spring Boot, Spring Data, Hibernate/JPA • Eventing/Streaming: Kafka (producers/consumers, Streams/KSQL optional) • APIs: REST/JSON, Async/Reactive where appropriate • Datastores: Postgres/Oracle, Redis/Cache; exposure to columnar/NoSQL a plus • Cloud & Ops: Docker, Kubernetes, CI/CD (GitHub Actions/Jenkins), Observability, Feature Flags • Data & Integration: Schema Registry, API/Swift connectivity, SFTP, ETL pipelines Education • BS/MS in Computer Science or related field (or equivalent practical experience).
