Transaction Services Interface enables access integration, parallel fulfilment, and service aggregation for switched transactions. Role: Overview Responsible for the analysis, design, development and delivery of software solutions Defines requirements for new applications and customizations, adhering to standards, processes and best practices Responsibilities - Own complex problems having dependency across services and facilitate cross-functional team interactions to drive resolution - Write code to build and enhance applications/services and promote code-reviews, code scanning, and other standard development practices to deliver high-quality artifacts to production. - Define, design, and develop procedures and solutions at a service level to meet the business requirements/enhancements - Drive prioritization decisions and trade-offs in working with product partners - Identify opportunities and build roadmaps to enhance primary service/function - Automate and simplify all aspects of software delivery and development actively evangelizing the need to automate and simplify where needed. - Drive seamless integration across all connected services to meet end-user expectations - Drive blameless postmortems culture to identify root causes of incidents and implement learnings - Introduce new technologies and architecture by following enterprise guidelines - Advocate for engineering principles outside of current organization/platform - Provide development and architecture guidance to team members - Build relationships and effective partnerships across organizations - Write and evaluate recommendations for job promotions based on an unbiased view of one's accomplishments - Conduct technical interviews for hiring engineering staff and raising the performance bar - Lead by example with hands-on approaches to demonstrate engineering excellence - Encourage staff to share and seek knowledge within their Guild/Program to drive reuse of patterns/libraries/practices and enhance productivity. - Design and implement high-performance, event-driven applications leveraging Java, Go, and modern messaging systems like NATS and Kafka. - Build scalable architectures and microservices using gRPC streaming and HTTP/2 for low-latency communication. - Drive system design for high TPS (transactions per second) environments ensuring reliability and fault tolerance. - Apply advanced design principles and patterns to deliver robust, maintainable solutions. - Engineer and optimize in-memory, high-performance distributed caches (e.g., Apache Ignite) to enable low-latency reads/writes and resilient data grids at scale. - Define caching strategies (read-through, write-through, near/cache aside) and tune partitioning, affinity, persistence, and eviction for predictable performance under high TPS. - Design and operate streaming and batch pipelines for real-time and near–real-time processing, ensuring exactly-once semantics, backpressure handling, and robust error recovery. - Orchestrate hybrid data workflows that combine streaming ingestion with batch reconciliation to maintain consistency, auditability, and SLA compliance. - Implement observability (metrics, tracing, logging) for caches and data pipelines, and conduct capacity planning and performance tuning (GC, thread pools, serialization). About You: Must have - - Java spring boot and Go lang with hands-on experience in building distributed systems. - Strong knowledge of gRPC streaming, HTTP/2 protocol, and asynchronous communication patterns - Experience with event-driven architectures, NATS, Kafka brokers, and designing systems for high throughput and scalability. - Hands-on experience with in-memory distributed caches (preferably Apache Ignite) including data grid design, cluster sizing, affinity mapping, and persistence configuration. - Strong understanding of cache consistency models, TTL/eviction strategies, and hot-key mitigation in high-throughput systems. - Practical expertise in streaming and batch processing—designing pipelines with checkpointing, idempotency, windowing, and schema evolution across environments. - Comfortable optimizing end-to-end data paths: serialization formats, network I/O, threading/concurrency, and resource tuning to meet stringent latency and throughput targets. - Proven ability to balance real-time processing with batch backfill/reprocessing, ensuring data correctness, resilience, and operational simplicity. - Has ability to write secure code in three or more languages (e.g., Java, JavaScript, C, C++, SQL) - Familiar with secure coding standards (e.g., OWASP, CWE, SEI CERT) and vulnerability management Has skills in building applications using open frameworks to achieve reuse and reduce development times (e.g., Spring Boot, Steeltoe, Angular, DXP, others) Understands internals of operating systems (Windows, Linux) to write interoperable and performant code Able to perform debugging and troubleshooting to analyze core, heap, thread dumps and remove coding errors Has skills to document and coach team on the development practices and coding guidelines (e.g., branching, peer reviews, library use, logging, scanning rules, test-driven development, error handling) Understands use cases for advanced design patterns (e.g., service-to-worker, MVC, API gateway, intercepting filter, dependency injection, lazy loading, all from the gang of four) to implement efficient code Has skills to undertake a technical review of code across applications and their dependencies to look for anti-patterns and promote continuous refactoring Understands and elaborates technical debt and operational issues to drive prioritization discussions with stakeholders to improve the run experience Understands system architecture to plan for platform and infrastructure capacity (e.g., database, compute, network, storage) and drives the dependency prioritization to reduce the delivery lead time Has skills to understand customer journeys and ensure a good customer experience by continuously reducing mean time to mitigate (MTTM) for incidents and ensuring high availability (99.95% as a starting point) Has skills to simplify deployment and eliminate software and infrastructure snowflakes using standardized platforms, ephemeral instances, and automation - Proven expertise in Java and Go with hands-on experience in building distributed systems. - Strong knowledge of gRPC streaming, HTTP/2 protocol, and asynchronous communication patterns.
