About Us: 

Delasport is where technology meets the excitement of sports and gaming! As a proven innovator in iGaming software, we provide everything from platform development to player account management. Our platform is designed to make every player feel like the star of the show, with personalized experiences and cutting-edge technology at its heart. 

Since our founding in 2010, we have won multiple international awards and have established a proven track record of excellence, stability, and overall success. This achievement only drives us to reach even greater heights. Currently, we are proud to have over 500 experts across various business fields and several offices in Bulgaria (Sofia and Plovdiv), Ukraine, and Malta. 

• Technical Quality Ownership - Set and enforce technical standards for code quality, testing practices, deployment procedures, and observability across all teams. Ensure deliverables consistently meet company and industry standards.
• Security & Compliance - Champion security best practices in application design and delivery. Drive secure coding standards, dependency management, and vulnerability remediation across the development lifecycle.
• Technology Decisions - Drive and consult on technology choices in collaboration with the Architect and engineering teams. Evaluate new tools, frameworks, and patterns with a clear focus on efficiency, maintainability, and long-term sustainability.
• Architecture & Design Guidance - Review and guide system designs, API contracts, data models, and integration patterns. Ensure business requirements are implemented following sound architectural fundamentals and established standards.
• Hands-On Engineering - Stay deeply hands-on with production code. Lead by example in modern Java (21/25), Spring Boot 3/4, PHP, Laravel, NodeJS, Kafka Streams, and cloud-native microservices. Conduct in-depth code reviews and contribute to critical path development.
• Observability & Operational Excellence - Define and drive observability standards (metrics, logging, tracing, alerting) to ensure production systems are transparent, diagnosable, and reliable.
• Technology Adoption - Drive the adoption of new technologies and practices across teams. Build proof-of-concepts, define migration paths, and ensure smooth rollouts with minimal disruption.
• Cross-Team Collaboration - Act as the technical mediator between Java teams, Team Leads, the Architect, and business stakeholders. Translate business requirements into sound technical guidance and ensure alignment across all parties.
• Knowledge Sharing - Foster a culture of technical excellence through design reviews, tech talks, documentation, and hands-on mentoring of senior engineers.

• Deep knowledge of Java (21+), PHP or NodeJS concurrency, JVM internals, and performance characteristics
• Strong experience with building production-grade microservices
• Strong expertise with Kafka and Kafka Streams — event-driven architectures, stream processing, schema evolution, and exactly-once semantics
• Solid understanding of REST API design fundamentals and synchronous integration patterns
• Hands-on experience with Kubernetes, GitOps (ArgoCD, Kustomize), and container orchestration
• Experience defining and implementing observability strategies (metrics, distributed tracing, structured logging, alerting)
• Strong understanding of application security practices, secure coding, and dependency management
• Solid database knowledge: relational and document databases, data modeling, and performance tuning

• Experience in iGaming, Sportsbook, or real-time transaction-heavy systems
• CDC architectures (Debezium)
• Redis or distributed caching strategies
• Performance tuning and benchmarking (JMH, async-profiler, JFR)
• Architecture patterns such as DDD, CQRS, or Event Sourcing
• Contributions to open-source projects
