Role description
Are you a Java Engineer working at a large enterprise and being told you're too hands-on, too technical, or think too much like a startup engineer? Imagine working at Intellibus to engineer platforms that impact billions of lives worldwide. Our Platform Engineering Team is trusted by some of the most reputable Financial Services, Insurance, and Trading organizations. We modernize mission-critical systems, solve large-scale engineering challenges, and deliver enterprise remediation programs. We are looking for a Lead Java Engineer who can lead technical initiatives while remaining deeply hands-on with architecture, development, troubleshooting, and modernization efforts. This role will focus on Java-based distributed systems while supporting modernization efforts involving legacy Progress OpenEdge (4GL/ABL) applications. We are looking for Engineers who can • Write enterprise applications in Java using Object-Oriented Design Principles. • Build Java Spring Boot REST Services and Microservices. • Design and develop event-driven systems using Kafka. • Utilize Java Streams API for high-volume real-time data processing. • Create Java Thread Executor Pools and concurrent processing solutions. • Use Java Lambda Expressions and Functional Programming concepts. • Design distributed cloud-native applications using Spring Cloud. • Implement resiliency patterns, including Circuit Breakers. • Design scalable database integrations using Hibernate and Spring Data. • Optimize application performance, business logic, and SQL queries. • Troubleshoot complex production issues across distributed systems. • Build highly available applications across Multi-AZ and Multi-Region deployments. • Develop scalable integration services and APIs. • Modernize legacy applications and integrate with Progress OpenEdge platforms. • Lead architecture reviews and technical design discussions. • Mentor engineers and establish development best practices. • Support production environments and mission-critical systems. • Navigate, troubleshoot, and debug applications running on Linux and Unix environments. Qualifications • 15+ years of software engineering experience. • 10+ years of hands-on Java development experience. • Strong experience with Java 8+ and Spring Boot. • Strong experience building RESTful APIs and Microservices. • Strong experience working in Linux and Unix environments. • Experience with distributed systems and event-driven architectures. • Experience with Kafka. • Strong SQL and database optimization experience. • Experience leading engineering teams or acting as a Technical Lead. • Strong debugging and production support experience. • Excellent communication and leadership skills. • Experience with Progress OpenEdge / Progress 4GL / ABL. • Experience modernizing legacy enterprise applications. • Financial Services, Insurance, Banking, or Trading industry experience. • Experience with AWS cloud technologies. • Experience with Kubernetes and containerized deployments. • Experience with Terraform and Infrastructure as Code. • Experience supporting high-throughput enterprise applications. What Success Looks Like You will drive the modernization and remediation of mission-critical enterprise applications, improve platform scalability, reliability, and performance, and successfully bridge legacy Progress OpenEdge systems with modern Java-based distributed architectures. You will mentor engineers, establish engineering best practices, lead technical decision-making, and deliver high-quality solutions that reduce operational risk while enabling the business to scale. Ultimately, you will be a key contributor in transforming complex legacy platforms into modern, resilient, cloud-ready systems. We work closely with • Java 8+ • Spring Boot • REST-based Microservices • Hibernate ORM • SQL • Messaging & Distributed Systems • Kafka • Event-Driven Architecture • Multi-Threaded Processing • AWS • Kubernetes (EKS) • Terraform • Docker • Linux • Unix • Progress OpenEdge • Progress 4GL (ABL) Compensation $75 - $80 / Hour Our Process • Schedule a 15-minute video call with someone from our Team • 4 Proctored GQ Tests (< 2 hours) • 30-45 min Final Video Interview • Receive Job Offer If you are interested in reaching out to us, please apply, and our team will contact you within the hour.
