Senior Java Developer

Why this role exists:

This role exists to architect and ship the high-performance backbone of our platforms. You’ll help us achieve global scalability by owning the end-to-end delivery of resilient Java-based microservices and mentoring the next generation of engineering talent.

What you’ll drive:

Architecture & Technical Decisions

• Design and evolve scalable microservices using Java 17+ and Spring Boot.


• Apply resilience patterns (Circuit Breaker, Bulkhead, Rate Limiting) to ensure systems thrive under pressure.


• Evaluate and select database strategies (PostgreSQL, NoSQL, Redis) based on specific performance trade-offs.


• Design event-driven architectures utilizing Kafka or RabbitMQ to handle real-time data flow.

Delivery & Execution

• Own the full development lifecycle—from initial requirement elicitation to production release.


• Ship clean, maintainable, and highly efficient code that sets the standard for the team.


• Optimize application performance by profiling JVM internals and fine-tuning garbage collection.


• Unblock the release pipeline by automating testing and improving CI/CD workflows in GitLab.

Quality & Reliability

• Enforce "Security by Design" and secure coding practices (OWASP Top 10) across all services.


• Drive continuous improvement in testing protocols, including integration, performance, and BDD.


• Identify and resolve complex production bottlenecks using monitoring tools like ELK or Datadog.


• Maintain comprehensive technical documentation that simplifies complex system designs for others.

Team Growth & Leadership

• Mentor junior and middle engineers through high-quality code reviews and technical guidance.


• Partner with Product Managers and Delivery Managers to align technical roadmaps with business outcomes.


• Foster an Agile culture by actively participating in planning, estimation, and iterative delivery.

What makes you a GR8 fit:

Must-have

• 5+ years of commercial experience in Java development (Senior level).


• Mastery of Spring Ecosystem (Boot, Data, Security) and Hibernate/JPA.


• Deep understanding of distributed systems: Microservices, Event-driven design, and CAP theorem.


• Strong Database expertise: Proficiency in complex SQL, indexing strategies, and transaction isolation.


• Hands-on DevOps mindset: Practical experience with Docker, Kubernetes, and CI/CD automation.


• Solid Cloud knowledge: Experience building and scaling applications in AWS (preferred).


• Architecture fluency: Ability to explain design trade-offs and visualize systems using UML or similar tools.

Nice-to-have

• Experience with GitLab CI and Infrastructure as Code (Terraform/Ansible).


• Familiarity with FinOps principles to optimize cloud resource consumption.


• Background in iGaming or high-frequency Fintech environments.


• Knowledge of reactive frameworks like Vert.x or Micronaut.
