Job Overview
Diyar United Company is seeking a highly skilled and experienced Senior Software Developer (Java & SQL) to join our dynamic IT team in Kuwait. This is a full-time position designed for a seasoned professional who excels in backend architecture, database optimization, and high-concurrency system design. As a Senior Developer, you will play a pivotal role in ensuring the stability, scalability, and efficiency of our enterprise-grade applications, particularly those handling heavy concurrent usage, such as student registration platforms. In this role, you will not only write clean, efficient, and maintainable Java code but also dive deep into database performance tuning. You will analyze system behavior under peak loads, identify bottlenecks, and implement advanced SQL tuning strategies, including execution plan analysis, indexing, and query refactoring. Your expertise will be critical in resolving complex production issues such as slow response times, timeouts, and database locks.
Key Areas of Impact:
- Application Architecture & Development: Designing and developing robust, scalable backend systems using modern Java frameworks. You will ensure that the codebase is optimized for maximum throughput and low latency.
- Database Performance Tuning: Working closely with relational databases to optimize queries, transactions, and overall database structure. Your hands-on experience with SQL performance tuning will prevent system degradation during high-traffic events.
- High-Concurrency Management: Architecting systems that can seamlessly handle thousands of concurrent users. This includes implementing efficient caching mechanisms, load balancing, and connection pooling.
- Production Troubleshooting: Serving as a key technical resource for diagnosing and resolving critical production issues. You will perform root cause analysis to prevent recurring system failures.
- Infrastructure Collaboration: Partnering with infrastructure and DevOps teams to tune Java Virtual Machines (JVM), application servers (such as WildFly and Tomcat), and database connection pools.
Why Join Diyar United Company in Kuwait?
Kuwait’s technology sector is expanding rapidly, and Diyar United Company is at the forefront of this digital revolution. By joining our team, you will have the opportunity to work on challenging projects that directly impact large-scale public and private systems. We offer a collaborative work environment where innovation is encouraged, and professional growth is supported. If you are a problem solver who thrives under pressure and possesses a deep passion for backend engineering and database optimization, we would love to hear from you.The Ideal Candidate Profile
To excel in this position, you should have a solid foundation in computer science principles and at least 5 years of professional experience in Java backend development. You must be comfortable working in Linux server environments and have a strong familiarity with monitoring and logging tools to proactively identify system anomalies. Experience with student information systems or registration platforms is highly desirable, as it aligns closely with our core projects. Furthermore, we value developers who are continuous learners. The tech landscape is constantly evolving, and we expect our senior engineers to stay updated with the latest industry trends, tools, and best practices. You should be able to mentor junior developers, conduct constructive code reviews, and maintain comprehensive technical documentation for all systems, fixes, and optimizations. This role requires excellent communication skills, as you will be translating complex technical concepts to non-technical stakeholders and collaborating with cross-functional teams.Key Job Details
