● Write clean, testable, and maintainable Go code following best practices.

● Participate in architectural design discussions and technical decision-making.

● Collaborate closely with product, frontend, and QA teams to deliver end-to-end features.

● Operate in a cloud-native, containerized environment using modern DevOps and CI/CD practices.

● Ensure the reliability, scalability, and performance of backend systems.

About You:

● 6+ years of experience in backend development, ideally in high-traffic or distributed systems.

● Strong proficiency in Go as a primary backend language. Experience with gRPC is highly valued.

● Deep understanding of distributed systems and service-oriented architecture.

● Hands-on experience integrating and managing third-party APIs and external services.

● Comfortable with cloud platforms, containerization, and CI/CD pipelines.

● Committed to software quality, clean architecture, and engineering best practices.

● Excellent written and spoken English communication skills.

● Proactive and collaborative mindset — you enjoy sharing ideas and improving team outcomes.

● Experience in iGaming and/or Laravel is a strong advantage (but not required).

What kind of culture can I expect?

Mature, mission-driven, and low-ego. We value clarity over noise, outcomes over theatrics, and pace without chaos. If you're one of the smartest minds in your craft and want to build with other experts, you'll feel at home here.
