Job Details:
Principal Software Engineer — Java
Lead architecture, design, and hands-on delivery for a security-critical, multi-tenant fintech platform that issues and manages virtual payment/transit cards across mobile wallets (Apple Wallet, Google Wallet) and EMV/contactless systems — including card tokenization and HSM-backed cryptography. You’ll own technical direction across the full lifecycle and raise the engineering bar for payment-grade systems.
Essential Duties and Responsibilities
•
Own architecture and design for scalability, security, and performance across a schema-per-tenant multi-tenant platform.
•
Provide hands-on technical leadership end to end, in a domain where financial and cryptographic correctness is paramount.
•
Build and evolve core subsystems using Java 17/21, Java EE, Spring / Spring Boot: virtual card lifecycle, payment tokenization (e.g., Mastercard MDES), key management, and wallet provisioning (APNs, Google Wallet).
•
Ensure reliable external integrations — card networks, key-management/HSM services, device notification, and downstream REST/SOAP endpoints — with retries, timeouts, and idempotency.
•
Design messaging/integration with Kafka and Apache Camel; caching with Redis.
•
Own data design and performance across PostgreSQL and Oracle (Liquibase migrations, Hibernate/JPA tuning).
•
Produce design docs, architecture diagrams, and threat models; mentor engineers on coding and secure-coding standards.
•
Drive CI/CD with Jenkins (pipeline-as-code), Gradle, and Docker.
