We’re looking for an experienced Middle/Senior Java Developer to join our friendly team!

Work at Exadel – Who We Are:
Since 1998, Exadel has been engineering its own software products and custom software for clients of all sizes. Headquartered in Walnut Creek, California, Exadel currently has 2000+ employees in development centers across America, Europe, and Asia. Our people drive Exadel’s success, and they are at the core of our values, so Exadel is a people-first cultured company.

About Our Customer: 
Founded in 2002, the customer is a New York-based analytics company, with 2,800 employees in various locations internationally. The company sells software and hardware products for client engagement management, security, surveillance, and business intelligence. The customer’s products are designed to assist clients in data analysis, specifically large data sets. 

About Our Project:
Developers will join an existing project team, focussing on building third-party integrations.

For the product to be usable, we need the ability to load and export a variety of datasets and statistics from third-party applications into the product. For example:

  • Agent statistics like current status, login time, etc.
  • Queue statistics like call volume, average handling time, average waiting time, etc.

Typically, this involves writing a Java-based component called an adapter which will collect these statistics from the third-party system and convert the data into the necessary format for the customer.  Generally, the data is obtained via APIs (Rest or SOAP), but this may involve Java-based APIs or database queries depending on the vendor we are integrating with. We also expect to write fully automated tests for these adapters using simulators to ensure quality and support customers using them in the field.


  • 2+ years of experience in working with Java
  • Experience of applications deployment in containers e.g., Spring Boot
  • Experience of developing and consuming API services – REST (SOAP beneficial)
  • Experience with version control systems e.g., Git
  • Experience of continuous integration e.g., Jenkins
  • Experience of following code review process
  • Experience of unit testing, e.g., Junit
  • Attention to details and troubleshooting skills
  • Excellent written and verbal communication skills

Nice to Have:

  • Knowledge of Gradle as a build tool
  • Knowledge of integration testing e.g., Cucumber or alternative
  • Experience of relational databases and basic queries
  • Knowledge of authentication mechanisms for API services
  • Test Driven Development


  • Write well-designed, testable, efficient code
  • Contribute in all phases of the development lifecycle
  • Ensure designs are in compliance with specifications
  • Support continuous improvement by investigating alternative technologies and presenting them for architectural review
  • Attend meetings
