Nowadays, we're on the hunt for a dynamic Backend Engineer!

Team Overview: 

As an online gaming company, our software is the heart of our business. We strive to create a safe, engaging and unparalleled player experience; we research, experiment and iterate. Our mission: to build a product and an organisation that puts the experience first, delivering high-quality products our players love while enabling our people to be productive and creative without unnecessary disturbances.
 

Responsibilities: 

• Design, build, and maintain backend services with a focus on reliability, scalability, and clean delivery.

• Take ownership of well-scoped features and components, from implementation and testing through deployment and production support.
• Work closely with other engineers, Product, and QA to deliver high-quality solutions aligned with team goals.
• Actively participate in code reviews, both giving and receiving feedback to improve code quality.
• Mentor and support junior engineers through technical guidance and day-to-day collaboration.
• Participate in technical interviews, typically focused on specific technologies or problem-solving areas.
• Contribute to improving engineering practices, tooling, and codebases within the team.

Requirements:

• 3+ years of hands-on backend engineering experience.
• Practical experience with Java, Spring Framework / Spring Boot, and building REST-based services.
• Hands-on experience with event-driven architectures, including message brokers such as RabbitMQ, Kafka, or similar (required).
• Experience working with relational databases (MySQL, PostgreSQL, OracleDB, or similar).
• Experience developing and maintaining distributed systems and microservices.
• A solid focus on code quality and automated testing practices (unit and integration tests).
• Comfortable using Git-based workflows and collaborating within cross-functional teams.

Nice to Have:

• Exposure to CQRS, Domain-Driven Design (DDD), event sourcing, or NoSQL databases.
• Familiarity with Test-Driven Development (TDD).
• Experience with Docker, CI/CD pipelines, or cloud platforms (e.g. GCP).
• Knowledge of Kotlin.

How We Work:

We operate in cross-functional Agile teams, collaborating through planning, reviews, and retrospectives.

We value clear communication, teamwork, and continuous improvement.

Mid engineers are expected to work independently on defined problems, support junior teammates, and grow toward broader technical ownership.

Our ABC values:

ASPIRE

At Casumo, "aspire" means pushing beyond the ordinary and transforming obstacles into stepping stones. Challenges are our breakfast of champions, and comfort zones are out of bounds. Mediocrity? Left behind. Our mantra? Dream big, aim high, and always be ready for the next adventure in innovation.

CARE

Care is our secret ingredient, the cherry on top of our game. It's not only about ensuring our players have a blast (responsibly, of course); it's about weaving a fabric of support so tight, even the toughest challenges can't tear us apart. From tailoring player experiences to being there for each other, we're all about creating memorable moments.
