## Description

Role Overview

We are hiring an experienced Senior Software Engineer to design, build and maintain high-performance,

secure Java back-end systems for a large-scale digital services platform. You will work end-to-end – from

solution design through implementation, testing and production support – collaborating with product managers

and cross-functional teams to deliver reliable, scalable services and well-designed APIs.

Work Location: Sharjah

Experience: 8+ Years

Notice Period: Immediate to 30 Days

UAE based candidates only

Key Responsibilities

• Design and develop high-performance, scalable back-end systems and effective APIs.

• Build and maintain well-functioning databases and applications.

• Implement security and data-protection controls across services.

• Write clean, maintainable, well-tested code; debug and resolve production issues.

• Produce clear technical documentation and participate in code reviews.

• Communicate with stakeholders and service providers to align technical requirements.

• Stay current with tools and practices to continuously improve the back-end platform.

Essential Requirements (Must-Have)

Education & experience

• Bachelor’s or Master’s degree in Computer Science or a related field.

• 5+ years’ hands-on software engineering experience at a senior level.

• Strong CS fundamentals: algorithms, data structures, OOP, design patterns, software architecture, database

design and UML.

Core backend

• Java (11+) and Spring Boot – current, hands-on, build-level experience (not architecture/oversight only).

• Oracle Database – SQL and PL/SQL, indexing, query tuning and reading execution plans.

• REST and SOAP web services – designing and consuming both.

• API security – JWT (access vs refresh tokens), Spring Security, and OAuth2 / OIDC.

• Oracle WebLogic and Apache Tomcat – deployment, tuning and troubleshooting on application servers.

Distributed systems, messaging & resilience (primary assessment area)

• Apache Kafka or RabbitMQ and event-driven architecture.

• Transactional outbox pattern for save-and-publish consistency.

• Idempotent consumers and duplicate-message handling (unique key + de-duplication).

• Resilience patterns – circuit breaker, retry with back-off, fallback, bulkhead and rate limiting (e.g.

Resilience4j).

• Distributed locking for scheduled jobs across multiple instances/pods (e.g. ShedLock, Redis or leader

election).

• SOA and microservices architecture; awareness of CQRS.

Performance & concurrency

• Diagnosing latency when CPU is low (thread- and connection-pool exhaustion, GC, blocking I/O).

• Query optimisation, avoiding full table scans, and resolving the N+1 problem (fetch join, entity graph,

batching).

• Optimistic vs pessimistic locking and handling race conditions.

• Memory-leak diagnosis using heap dumps and profilers
