We are looking for a Senior Back-End Developer to take ownership of complex backend systems, lead technical architecture decisions, and mentor the next generation of developers. You will work with cutting-edge technologies to design, build, and optimize services that impact billions of mobile users worldwide.
This is a hands-on leadership role — ideal for someone who thrives in a fast-moving environment, enjoys collaborating across functions, and is driven to deliver scalable, reliable, and future-proof systems.
Requirements:- Bachelor’s degree in Computer Science or equivalent practical experience;
- 6+ years of professional Java development experience;
- Proven track record in designing and delivering complex distributed systems and microservices (Docker, Kubernetes);
- Strong understanding of scalability, concurrency, and performance optimization challenges;
- Hands-on experience with CI/CD tools and automated build/deployment pipelines;
- Proficiency in Spring & Spring Boot frameworks;
- Excellent communication skills and the ability to influence technical direction across teams;
- Experience running applications on Kubernetes, with a focus on designing services that scale efficiently and consume resources effectively (rather than cluster administration);
- Ability to measure and improve application performance using profiling, benchmarking, and APM tools (e.g., JFR, JMeter, Micrometer, New Relic, Datadog).
- Design and develop highly scalable, modular backend applications and APIs using Java and Spring Boot;
- Own the full development lifecycle — from requirements analysis, design, coding, and testing to deployment and monitoring in production;
- Lead initiatives to improve system scalability, performance, and security;
- Collaborate closely with Product, Algo, DevOps, BI, and Marketing to deliver integrated, business-driven solutions;
- Ensure observability through robust logging, metrics, and alerting with tools like Prometheus, Grafana, Kibana;
- Drive adoption of engineering best practices, code quality standards, and technical documentation;
- Mentor and guide junior developers, fostering knowledge sharing and continuous improvement.
- Background with NoSQL databases (MongoDB, Couchbase) and SQL databases;
- Knowledge of reactive programming (Spring WebFlux);
- Familiarity with monitoring and alerting tools such as Prometheus, Grafana and Kibana.
- Help and support from our caring HR team;
- 20 days of vacation;
- Health Insurance;
- Gym Subscription (Multisport);
- The exchange of experience and work with talented colleagues;
- Last but not least - valuable compensation for your efforts.
