Senior Java & Golang Developer

Senior Java & Golang Developer

INTRODUCTION

We are hiring a Senior Java & Golang Developer with strong experience of building and supporting enterprise-scale backend applications and cloud-native microservices to join our Information Technology group. The ideal candidate has 7+ years of Java development experience and 5+ years of hands-on Golang experience, with deep expertise in gRPC/Protocol Buffers, microservices architecture, Kubernetes, distributed systems, and production support.

This role is responsible for designing, developing, deploying, and supporting high-performance backend services operating within a large-scale insurance and administrative processing environment. The candidate should be comfortable working across the full SDLC, collaborating with onshore/offshore teams, participating in architecture discussions, and delivering production-quality code through modern CI/CD practices.

REQUIRED SKILLS

• 7+ years Java (Java 17+) | 5+ years Golang
• Spring Boot, Spring Cloud and Microservices Architecture
• gRPC / Protocol Buffers and RESTful APIs
• Docker, Kubernetes (AKS) and Azure Cloud
• SQL Databases: Oracle, SQL Server, MySQL
• Batch Processing and Job Scheduling (Control-M or equivalent)
• CI/CD: GitHub Actions and/or Azure DevOps
• Git: Branching Strategies, Commits, Pull Requests, Code Reviews
• Production Support and Incident Management
• Distributed Systems and Concurrency
• Observability: Prometheus, Grafana

JOB FUNCTIONS

• Design, develop, and maintain enterprise-grade Java applications and high-performance Go-based backend services within a large-scale administrative processing environment.
• Participate actively across the Software Development Lifecycle (SDLC) including requirement analysis, design, development, unit/integration testing, and release support.
• Build, maintain, and optimize RESTful APIs and gRPC/Protocol Buffer services using both Java (Spring Boot) and Golang for high-throughput, highly available systems.
• Design, develop, and support microservices-based architectures using Spring Boot, Spring Cloud, and Go - applying clean separation of concerns, service discovery, centralized configuration, and API gateway patterns.
• Write efficient, reusable, and testable code in both Java and Go, adhering to language-specific best practices and engineering standards.
• Work with distributed systems, handling concurrency, fault tolerance, and scalability - including Go goroutines, channels, and synchronization primitives.
• Implement and support batch processing jobs and nightly batch cycles, including job configuration with predecessor/successor dependencies, FTP-based file transfers, automated notifications, and failure troubleshooting.
• Integrate applications with relational databases (Oracle, SQL Server, MySQL) using Hibernate, Spring Data JPA, and native Go database drivers; apply strong SQL, data modeling, indexing, and query optimization skills.
• Provide production support for business-critical applications, including root cause analysis, defect resolution, incident response, performance tuning, and on-call support within defined SLAs.
• Collaborate with DevOps teams to containerize services using Docker and deploy to Kubernetes (AKS) environments.
• Participate in CI/CD pipeline activities using GitHub Actions and/or Azure DevOps, including automated builds, test execution, and deployment workflows.
• Follow Git-based version control practices including branching strategies, commits, pull requests, and code reviews aligned with team standards.
• Implement logging, monitoring, tracing, and observability standards across services.
• Author and maintain designated sections of Technical System Design Documents (TSD).
• Participate in Agile/Scrum ceremonies, provide accurate effort estimates, and communicate progress and blockers proactively.

QUALIFICATIONS

• 7+ years of hands-on experience developing, debugging, and supporting production-grade Java (17+) enterprise applications, with strong understanding of core Java concepts including object-oriented programming, collections, exception handling, and modern Java features.
• 5+ years of hands-on Golang development experience, with demonstrated ability to design, develop, debug, and reason through complex Go systems - goroutines, concurrency patterns, channels, synchronization primitives, memory management, and performance optimization.
• Good working knowledge of the Spring ecosystem: Spring Boot, Spring MVC, Spring Security, Spring Data JPA, and Spring REST.
• Hands-on experience developing and supporting microservices-based applications using Spring Boot and Go, applying cloud-native design patterns.
• Experience building, consuming, and optimizing RESTful APIs and gRPC/Protocol Buffer services in production environments.
• Experience with batch processing concepts such as job configuration, scheduling, nightly cycle support, predecessor/successor dependencies, file transfers, automated notifications, and failure troubleshooting using enterprise workload automation platforms (e.g., Control-M or equivalent).
• Experience providing production support including incident analysis, root cause identification, performance tuning, defect resolution, and on-call support within SLA-driven environments.
• Hands-on experience with relational databases including Oracle, SQL Server, and MySQL; proficient in SQL, stored procedures, ORM frameworks (Hibernate, Spring Data JPA), and native Go database libraries.
• Strong understanding of data modeling, indexing, and query optimization techniques.
• Experience with Docker and containerization best practices.
• Hands-on experience deploying, troubleshooting, and supporting applications on Azure Kubernetes Service (AKS) or comparable Kubernetes environments; familiarity with deployments, services, scaling, and configuration management.
• Experience with Git including branching strategies, commits, pull requests, rebasing, and collaborative code review workflows.
• Familiarity with CI/CD pipelines using GitHub Actions and/or Azure DevOps - including automated builds, test execution, and deployment to non-production and production environments.
• Experience with unit testing, integration testing, and performance benchmarking in both Java (JUnit, Mockito) and Go.
• Familiarity with code quality tools such as SonarQube.
• Experience with build tools such as Maven or Gradle (Java).
• Understanding of SOLID principles, Object-Oriented Design (OOD), API design standards, versioning strategies, scalability, resilience, and fault-tolerant architecture.
• Experience with observability and monitoring tools (Prometheus, Grafana).
• Command of Linux/Unix environments including command-line tools and shell scripting.
• Familiarity with Azure DevOps (ADO) for tracking user stories, tasks, and sprint work items.

NICE TO HAVE

• Domain exposure to life insurance, health insurance, or financial services administration.
• Experience with NoSQL databases such as MongoDB or Redis.
• Experience with message broker / event-streaming platforms such as Apache Kafka or RabbitMQ.
• Familiarity with OpenAPI/Swagger documentation and API security concepts such as OAuth2 and JWT.
• Experience with API gateway solutions (e.g., Kong, NGINX, AWS API Gateway).
• Experience with file transfer mechanisms between Azure cloud storage and on-premises systems.

SOFT SKILLS

• Strong problem-solving and analytical skills with the ability to debug and work through complex technical issues independently before escalating.
• Strong organizational and time management skills, with experience working in an onshore/offshore delivery model and the ability to manage multiple tasks across development and support responsibilities.
• Collaborative team player who communicates openly, asks questions early, and shares knowledge across onshore and offshore team members across multiple time zones.
• Proactively identifies opportunities to improve delivery speed or quality through automation, tooling, or process improvements - and brings those ideas forward to the team.
