Senior Java Developer (Billing team)

Say hello to opportunities.

If you’re looking to be part of what’s next in communication, you’re in the right place.

At RingCentral, we believe the best customer experiences happen when humans and AI work together. Our agentic voice AI portfolio—AIR, AVA, and ACE—brings together automation, assistance, and insights across the entire conversation lifecycle. The result? More seamless, intelligent experiences for businesses everywhere.

With $2.5B+ in ARR and $250M invested in R&D annually, we’re building the future of AI-powered business communications.

This is where you and your skills come in. We’re currently looking for a Senior Java Developer for our backend team in the Billing department.

This role requires on-site presence at our office 4 days a week to support effective collaboration and teamwork.
 

What we do:

We build, maintain, and evolve a broad set of microservices that power integrations with payment systems, develop integrations for new customer signup, support the purchase flow, and keep the Billing customer portal running smoothly. Our area of responsibility includes dozens of microservices, hundreds of thousands of lines of code, and high-availability production systems with zero downtime that help thousands of customers signup, buy, and pay for the company’s services every day.

How we do it:

We write Java, make extensive use of the Spring ecosystem, and rely on Oracle Database and RabbitMQ to manage data flows. We deploy to Docker/Kubernetes, supported by GitLab and Jenkins-based CI/CD and a comprehensive monitoring stack.
 

What we expect from our future colleague

• 5+ years of Java development experience — Java is the main language you will be working with every day.

• Experience with large projects, complex business logic, and high-availability production systems — because this is exactly the kind of environment you will be working in.

• Hands-on Spring experience — we use the framework extensively, so a solid understanding of how it works under the hood will be very useful.

• Experience with relational databases — we trust Oracle Database, but experience with similar technologies is also very welcome.

• A strong habit of testing your code — we have a lot of tests, and we rely on them.

• A sense of ownership and responsibility for the codebase — because you will have both the opportunity and the need to make decisions, shape architecture, and build applications in the way you believe is right.

• Business fluency in both English and Russian language in speaking and in writing.

What else will be helpful

• Experience and confidence using AI tools in daily work — we actively use modern AI-powered development tools and will be happy to see fresh experience and enthusiasm.

• Docker, Kubernetes, and Jenkins — because these are part of the path from code to production.

• RabbitMQ — because it is our default message broker.

• JVM profiling, analysis, and timely optimization skills — because high-load production systems naturally create problems that require this kind of expertise.

What we offer: 

• Well-coordinated professional team.

• Cutting edge technologies, interesting and challenging tasks, dynamic project, great opportunities for self-realization, professional and career growth.

• Additional Health and Life Insurance Package.

• Employee Assistance Program.

• 25 vacation days.

• 102,26 EUR/200 BGN Digital Food Vouchers.

• 61, 36 EUR/120 BGN Gross as part of the salary for Working Expenses Allowance.
