What are some common challenges Senior Java Developers face when working on large-scale enterprise projects?

Senior Java Developers often encounter challenges such as maintaining code quality across large codebases, managing dependencies between modules, and ensuring optimal application performance. Collaborating with cross-functional teams—including QA, DevOps, and product management—requires clear communication and effective problem-solving. Additionally, staying updated with the latest Java frameworks and best practices is essential for delivering scalable and maintainable solutions in complex enterprise environments.

How much do senior Java developers make?

Rate: $90-$100/hr INC

Location: Downtown Toronto (1 day onsite)


Your New Company

Join a high-performing digital engineering team within a leading, enterprise-scale organization focused on building modern, scalable platforms. This team operates in a fast-paced environment, driving innovation through microservices and distributed architecture to support millions of users across digital products.


Your New Role

As a Senior Backend Developer, you will play a critical hands-on role in designing, building, and maintaining scalable backend systems and APIs. You will contribute directly to the development of microservices within a distributed architecture, while also supporting ongoing enhancements and maintenance of existing systems.

This is a highly technical, coding-heavy role requiring strong ownership and deep backend expertise.

Key Responsibilities:

  • Design, develop, and maintain scalable backend services using Java and Kotlin
  • Build and optimize APIs within a microservices architecture
  • Drive system design and contribute to architectural decisions across distributed systems
  • Write high-quality, production-ready code with strong testing practices
  • Maintain and enhance existing backend services and microservices
  • Work within event-driven architectures supporting real-time systems
  • Collaborate closely with cross-functional engineering teams


What You’ll Need to Succeed

  • 10+ years of backend development experience, with a strong focus on building scalable systems
  • Proven senior-level experience as a hands-on Backend Developer (not just design/lead)
  • Strong expertise in Java and Kotlin
  • Demonstrated experience building scalable APIs and distributed systems
  • Deep experience with microservices architecture
  • Strong hands-on experience with Spring / Spring Boot
  • Solid knowledge of SQL and relational databases
  • Experience working with event-driven architectures
  • Strong system design capabilities and ability to influence architecture
  • Experience with unit testing and development testing practices
  • Proven experience maintaining and evolving existing production microservices

Nice-to-Have:

  • Experience with Google Cloud Platform (GCP)


What You’ll Get in Return

  • Opportunity to work on large-scale, high-impact backend platforms
  • Exposure to modern engineering practices across distributed systems
  • A highly collaborative, engineering-driven team environment
  • Competitive compensation aligned to senior-level market rates
  • Flexible hybrid working model
