About Us: 

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

Since 2010, we've made a significant impact in industry, earning awards and expanding our global presence. With offices in Bulgaria, Ukraine, and Malta, our team of over 500 experts is constantly driving innovation and striving for excellence. 

Your Team:

The Engineering Excellence Team is for engineers who build the systems that power everything else. No product tickets. No UI tweaks. No support loops. You’ll create the tools, standards, and frameworks that make every development team faster and stronger.

This is deep technical work with massive impact - shaping architecture, unifying processes, and defining how engineering is done across the company. A place for senior engineers who want to build the backbone, not the features.

This is not a product team. It’s a technical excellence engine for people who want to build the systems behind the systems - and elevate the whole company through world‑class engineering. 

How You’ll Make an Impact:  

• Design and build foundational backend frameworks, libraries, and services that are reused across all engineering teams.
• Define and drive backend architecture standards - from service design and communication patterns to scalability, resilience, and security.
• Create and evolve shared platform solutions (e.g. service templates, common libraries, reference architectures) that accelerate development and reduce duplication.
• Establish best practices for building, testing, and operating Java services, ensuring consistency and high quality across all codebases.
• Develop and maintain core platform capabilities (e.g. service orchestration patterns, API standards, integration approaches) used company-wide.
• Partner with engineering teams to identify inefficiencies, remove bottlenecks, and enable faster, more reliable backend development.
• Drive initiatives to standardize and modernize the backend stack, improving performance, scalability, and maintainability across systems.
• Act as a technical leader through architecture reviews, hands-on guidance, and mentorship, raising the engineering bar across teams.
• Continuously evaluate and introduce tools, patterns, and technologies that improve scalability, reliability, and developer productivity at scale.

Employees may be required to participate in an on-call rotation, ensuring availability outside regular working hours to respond to urgent issues as needed as per the On call policy.

 Who You Are:  

• 5+ years of backend development experience with strong expertise in Java and object-oriented design. 
• Solid knowledge of design patterns, system architecture, and scalability principles. 
• Hands-on experience with databases (SQL/NoSQL) and message-driven systems (e.g., Kafka, RabbitMQ). 
• Familiar with containerization and orchestration (Kubernetes, Docker). 
• Comfortable with automated testing (unit, integration, performance). 
• Proven track record building and supporting production-grade, high-load systems. 
• Thrive in a dynamic, fast-changing environment with shifting priorities. 
• Strong communicator with a proactive, ownership-driven mindset.
