Job Description

We are looking for a Senior Backend Engineer (Java) with strong experience in building scalable, high-performance backend services and REST APIs using Java and Spring Boot. The ideal candidate will have hands-on experience developing microservices, event-driven systems, and distributed applications that operate reliably under heavy load.

The role involves designing and developing backend services, working with relational databases and caching technologies, implementing event-driven architectures, and optimizing application performance. You will also contribute to CI/CD pipelines, automated testing, code reviews, and software design practices.

Key Responsibilities

  • Design, develop, and maintain high-performance backend services and REST APIs using Java and Spring Boot.
  • Build and maintain scalable microservices with a focus on reliability, maintainability, and performance.
  • Develop event-driven architectures and asynchronous processing flows using Kafka or similar streaming platforms.
  • Design and optimize relational database solutions, including PostgreSQL, with a strong focus on query performance and efficient data handling.
  • Implement and optimize caching solutions using Redis, Ignite, or similar technologies.
  • Develop and integrate gRPC services for efficient communication between distributed services.
  • Design and implement multi-tenant backend services, ensuring appropriate tenant isolation, scalability, and security.
  • Containerize and deploy services using Docker and Kubernetes.
  • Contribute to CI/CD pipelines and automated deployment processes.
  • Write unit, integration, and performance tests to ensure application reliability and quality.
  • Apply appropriate design patterns, clean code principles, and software engineering best practices.
  • Participate in code reviews, technical discussions, and architectural decisions.
  • Perform performance profiling, troubleshooting, and tuning to optimize services under heavy workloads.
  • Monitor and analyze application performance, database queries, resource utilization, and system bottlenecks.
  • Collaborate with other engineers and teams to design and deliver reliable distributed systems.

Requirements

  • 5+ years of professional software development experience, with strong hands-on experience in Java.
  • Strong production experience with Java and Spring Boot.
  • Proven experience building microservices and REST APIs at scale.
  • Hands-on experience with Kafka or similar event-streaming platforms.
  • Strong knowledge of PostgreSQL or other relational databases, including query optimization and database performance.
  • Experience with Redis, Apache Ignite, or similar caching technologies.
  • Experience with gRPC and distributed service-to-service communication.
  • Experience designing multi-tenant applications and services.
  • Experience with Docker and Kubernetes.
  • Good understanding of CI/CD practices and deployment automation.
  • Strong knowledge of unit testing, integration testing, and automated testing practices.
  • Good understanding of software design patterns, clean code, and SOLID principles.
  • Experience participating in code reviews and collaborative software development.
  • Practical experience with performance profiling, load testing, troubleshooting, and application tuning.
  • Strong understanding of scalable, reliable, and distributed backend architectures.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
