Summary
✨ AI‑Generated
A backend engineering role requiring 5+ years of hands-on microservices development with Java 17+ and Spring Boot. You will design distributed, highly available systems and work extensively with Kubernetes, Docker, REST APIs, PostgreSQL, and Redis, with additional exposure to networking and private connectivity considered beneficial.
Highlights
Build highly available and fault-tolerant backend systems handling high-volume concurrent transactions, with deep exposure to modern Java, cloud-native infrastructure, databases, caching, and distributed architectures.

Required Skills & Experience
5+ years of hands-on microservices development in Java 17+ with Spring/Spring Boot experienceExperience building distributed, highly available, fault-tolerant systems supporting high-volume concurrent transactionsExperience with Kubernetes, Docker for container orchestration and deployment (understanding of nodes and pods and being able to write Docker files)Experience with Rest/Restful API development experience - gRPC is preferredExperience designing and working in PostgreSQL database including schemas, migration, access patterns, integrity, performance, reliability, backups, replication, and recoveryDesign and implement Redis caching and data-synchronization strategies, including TTLs, invalidation, consistency, and cache performance
Nice to Have Skills & Experience
Networking protocols relevant to distributed microservices (TCP, gRPC, gNMI, and/or real-time communication protocols)Private connectivity patterns: site-to-site VPN, private DNS, hub-and-spoke network topologiesBackground in satellite, telecom, or network management systems (NMS, ONAP, OAM/IP, SIP/RTP)
Job Summary
Insight Global is looking to bring on a Senior Backend Developer strong with Java (Java 17+) and Spring Boot experience.
You will be building highly available, large-scale distributed systems in a cloud-native environment.
You would be working on a mission-critical Azure-based platform that serves as a central control unit, where low latency, reliability, and resilience are critical.
The role involves designing and maintaining Java microservices, deploying services on Kubernetes using Helm, and optimizing service-to-service communication using gRPC, REST, and messaging protocols.
A strong understanding of distributed systems, networking performance, scalability, fault tolerance, and microservices architecture is essential, as you will help shape secure, high-performance services that operate across multiple regions and environments.
Key Responsibilities
Design, develop, and maintain Java (Java 17+) services within a distributed, event-driven architecture using Spring Boot.Package, deploy, and operate microservices on Kubernetes using Helm across multiple environments (dev/test/prod).Contribute to service decomposition, domain boundaries, and API design with a focus on latency, throughput, reliability, and backward compatibility.Design and implement reliable service-to-service communication using REST, gRPC, and messaging protocols.Support protocol-agnostic ingress suitable for long-lived or reconnect-sensitive traffic.Help optimize networking concerns (TCP behavior, connection pooling, backoff, circuit breaking) for high-scale traffic.Design, maintain, and optimize PostgreSQL schemas, migrations, access patterns, integrity, performance, reliability, backups, replication, and recovery.Design and implement Redis caching and data-synchronization strategies, including TTLs, invalidation, consistency, and cache performance.
