Job Title

Senior Principal Engineering Leader, Legacy Transformation

What does a successful Senior Principal Engineering Leader — Legacy Transformation do?

As a Senior Principal Engineering Leader focused on Legacy Transformation, you will define and advance the target engineering platform for a regulated fintech environment operating at bank-grade reliability. You will work across platform engineering, application engineering, architecture, security, and operations teams to modernize legacy services into cloud-native platforms. Your work will reduce operational risk, improve delivery consistency, and support secure, resilient experiences for clients and consumers.

What you’ll do:

• Define and deliver target platform architecture for application programming interface (API) gateways, service mesh, developer platforms, shared runtime services, identity, authorization, observability, and internal engineering standards

• Lead decomposition of monolithic and legacy platforms into bounded microservices with clear ownership models, defined data contracts, and controlled migration approaches

• Design and govern zero-downtime migration patterns for critical payment, account, customer, and transaction services where service disruption creates client, regulatory, or settlement risk

• Establish technical standards for Java and Go services, Kubernetes, Envoy, Istio, Terraform, continuous integration and continuous delivery (CI/CD), secrets management, resilience testing, and production readiness reviews

• Manage and develop senior engineering talent, including Staff and Senior engineers, through technical coaching, design reviews, and performance guidance

• Lead technical direction across transformation programs, align engineering priorities across teams, and drive consistent execution against architecture, reliability, and operational objectives

• Raise the engineering bar through review of consequential designs, operational controls, reliability practices, and measurable platform adoption outcomes

• Responsibilities listed are not intended to be all-inclusive and may be modified as necessary.

What you will need to have:

• 13+ years of experience in software engineering, platform engineering, or architecture roles building and operating large-scale financial technology, payments, banking, wallet, ledger, commerce, or similar regulated platforms

• 5+ years of experience defining architecture and leading modernization programs for platforms serving millions of customers or hundreds of millions of transactions

• 5+ years of experience managing and developing teams

• 10+ years of experience designing and delivering distributed systems using Java, Go, Kubernetes, cloud infrastructure, API gateways, service mesh, observability tooling, and infrastructure as code

• 8+ years of experience designing reliable financial systems with controls for authorization, capture, settlement, ledger consistency, reconciliation, auditability, idempotency, duplicate prevention, and financial-grade error handling

• 5+ years of experience implementing engineering controls aligned to PCI Data Security Standard (PCI-DSS), Service Organization Control (SOC), General Data Protection Regulation (GDPR), data residency, encryption, audit logging, and structured change management practices

• Bachelor's degree in Computer Science, Engineering, Information Technology, or a related field, or equivalent combination of education, related experience and/or military experience

• Experience leading modernization in a tier-one fintech, payments, commerce, banking technology, or cloud platform environment

What would be great to have:

• Experience with bounded context design, saga-based workflow patterns, and migration controls for high-risk transactional services

• Experience building shared internal developer platforms and engineering standards adopted across multiple product or platform teams

• Master's degree in Computer Science, Engineering, or a related field, or equivalent combination of education, related experience and/or military experience
