Job description

We have an opportunity to impact your career and provide an adventure where you can push the limits of what's possible.

As a Lead Software Engineer at JPMorganChase within the Commercial & Investment Bank Payments Technology Team, you are an integral part of an agile team that works to enhance, build, and deliver trusted market-leading technology products in a secure, stable, and scalable way. As a core technical contributor, you are responsible for conducting critical technology solutions across multiple technical areas within various business functions in support of the firm's business objectives. You will drive significant business impact through your capabilities and contributions, and apply deep technical expertise and problem-solving methodologies to tackle a diverse array of challenges that span multiple technologies and applications. You will design, develop, and optimize high-performance, low-latency OLTP systems that power mission-critical financial applications. You will build scalable, fault-tolerant platforms engineered for sub-millisecond response times that handle a high volume of transactions, ensuring data consistency, high availability, and regulatory compliance.

Job Responsibilities

• Regularly provides technical guidance and direction to support the business and its technical teams, contractors, and vendors, with a focus onlow-latency Java/Spring Boot OLTP architecturesand enterprise messaging patterns
• Develops secure and high-quality production codeand reviews and debugs code with an emphasis on latency-critical code paths, lock-free data structures, and efficient memory allocation
• Drives decisions that influence the product design, application functionality, and technical operations and processes
• Serves as a function-wide subject matter expert inlow-latency OLTP systems, real-time transactional processing, and event-driven architecturesacross the Java/JVM ecosystem
• Actively contributes to the engineering community as an advocate of firmwide frameworks, tools, and practices of the Software Development Life Cycle
• Influences peers and project decision-makers to consider the use and application of leading-edge technologies
• Adds to the team culture of diversity, opportunity, inclusion, and respect
• Architect and implement distributed OLTP applications to minimize transactional latency
• Collaborate with SRE/DevOps teams to deploy and monitor OLTP services in cloud-native environments (AWS, GCP, Azure)

Required Qualifications, Capabilities, and Skills

• Formal training or certification on software engineering concepts and5+ years of applied experience building low-latency, high-throughput OLTP systems in Java
• Hands-on practical experience delivering system design, application development, testing, and operational stability forlatency-sensitive transactional platforms using Spring Boot
• Advanced proficiency in Java (11/17/21+)with deep understanding of concurrency primitives, JVM internals, GC tuning, and performance-critical coding patterns
• Expert-level knowledge of relational databases including execution plan analysis, index optimization, lock contention reduction, partitioning strategies for OLTP workloads
• Proven experience designing low-latency APIs including Protocol Buffers schema design, connection multiplexing, streaming RPCs, and API rate limiting under high-concurrency conditions
• Deep expertise with Apache Kafkafor real-time event streaming in OLTP pipelines, including producer batching/compression tuning, consumer lag minimization, partition strategies for ordered processing, andJMS-based messaging (IBM MQ, ActiveMQ)for guaranteed delivery in transactional workflows
• Ability to tackle design and functionality problems independently with little to no oversight
• Practical cloud-native experience, including containerized deployment of latency-critical Spring Boot services
• Experience in Computer Science, Computer Engineering, Mathematics, or a related technical field
• Strong communication and collaboration skills for working in cross-functional teams

Preferred Qualifications, Capabilities, and Skills

• Experience designinghigh-availability, multi-region active-active OLTP architectureswith synchronous/asynchronous replication, conflict resolution, and sub-millisecond failover strategies
• Hands-on experience withlow-latency data access patterns
• Prior experience inreal-time payments, fraud detection, or financial transaction processingwhere strict data consistency are non-negotiable
• Strong knowledge ofdatabase security, access controls, and regulatory compliance
• Familiarity withperformance engineering tooling: JVM profilers, load testing frameworks, and systematic latency benchmarking (p50/p99/p999) across the full Spring Boot/Kafka/gRPC/JMS stack
