Job Overview

We are looking for an experienced Senior Java / Spring Boot Backend Engineer to provide hands-on technical support for an ongoing software engineering and cloud platform project.

The role involves designing microservices and event-driven architectures, building and scaling high-concurrent systems, optimizing performance, and integrating messaging queues and in-memory caches like Redis.

The engagement requires approximately 2 hours of support per day, with the possibility of extending working hours depending on project requirements.

This is not a full-time employment opportunity. We are specifically seeking professionals with practical, hands-on experience in Java, Spring Boot, microservices, and cloud/DevOps practices who can provide technical guidance and resolve complex architecture-related challenges.

• Caching & Event Storage: Hands-on experience with Redis and event storage mechanisms for high-throughput performance.
• Messaging & Middleware: Working knowledge of messaging queues to enable asynchronous processing and scalable systems.
• DevOps & Cloud: Familiarity with DevOps processes, CI/CD pipelines, Git version control, and Azure cloud environments.
• Algorithms & Optimization: Strong problem-solving skills utilizing Data Structures, Algorithms, and Test-Driven Development (TDD).

Key Responsibilities

• Design, build, and optimize backend microservices and event-driven architectures based on project requirements.
• Develop clean, maintainable, and well-tested Java code adhering to SOLID principles and TDD practices.
• Implement performance optimization, memory management, and multi-threading solutions for high-concurrent systems.
• Configure and manage Redis caches, event storage mechanisms, and messaging queues.
• Support DevOps efforts, including CI/CD pipelines and deployment processes on Azure.
• Troubleshoot configuration, performance bottlenecks, and system reliability issues.
• Maintain comprehensive documentation, architecture patterns, and technical guidelines.
• Collaborate with engineering, DevOps, and project stakeholders within an Agile development framework.

Required Experience

• Bachelor’s or Master’s degree in Computer Science or a related field.
• Hands-on experience developing, scaling, and maintaining Java and Spring Boot applications.
• Practical experience with microservices, event-driven architectures, and messaging queues.
• Demonstrated knowledge of Redis, multi-threading, memory management, and system performance tuning.
• Experience with TDD, Git, CI/CD pipelines, and DevOps workflows (Azure exposure is a plus).
• Strong analytical, problem-solving, and communication skills within Agile teams.
• Ability to work independently and provide remote technical support.
