EPAM’s Financial Services Practice is looking for exceptionally talented people to join our team of world class engineers. Our clients are some of the world’s largest and most innovative banks, investment banks and wealth management institutions.


Quality Engineering team within our client is about creating an ecosystem to build a world beyond waiting for all delivery teams to help achieve time-to-market, quality excellence, and higher customer satisfaction within all verticals including core, emerging payments, and value-added services.

Unlike similar performance tester roles in other organizations, this position needs deep understanding of architecture stacks and performance patterns – in addition to performance tools and performance testing- to understand business requirements and help architect/fine-tune systems for better performance early in the development life cycle.

This position will be part of Performance Engineering team within Quality Engineering and is responsible for ensuring that performance (end-to-end response times, throughput, transactions per second, capacity, etc.) of the client’s applications meet or exceed customer expectations.

What You’ll Do

  • Coordinate requirements review and performance testing activities to ensure the quality and functionality of our client’s assigned developed systems;
  • Document performance test strategy and test plans covering environment, schedule, test data set up, testing techniques, and key SLA metrics keeping end-user requirements and customer experience in mind;
  • Conduct manual and automated performance testing, handle performance defects, and fix performance issues covering platform hardware analysis, scalability, and application profiling (JVM, databases, etc.);
  • Partner with operations, product, and development teams to develop real-time performance dashboards and provide periodic updates on application performance to partners;
  • Define and implement best practices for end-to-end application performance management solutions including Proof of Concepts and Tools evaluation and selection – specifically in emerging technologies (web, mobile);
  • Document problems, monitor resolutions and retain documentation necessary to share knowledge with performance engineering and application teams;
  • Develop business and product knowledge over time and share such knowledge to mentor newer team members. This is not a management position; however, this position is expected to provide strong leadership to junior members of the staff;
  • Implement consistent company and department testing standards and procedures;
  • Demonstrate a clear path of services adoption to partners through demos, presentations, and prototypes.

What You Have

  • Deep understanding of architecture stacks and performance patterns – in addition to performance tools and performance testing – to understand business requirements and help architect/fine-tune systems for better performance early in the development life cycle;
  • Ability to define performance test plans and roadmaps, as well as partner with delivery teams to implement the strategy;
  • Prior experience installing, configuring and using performance testing tools (i.e. LoadRunner and JMeter) and performance monitoring tools (i.e. Dynatrace and Splunk);
  • Experience in scripting and performance testing web/mobile applications and web services (SOAP and REST APIs);
  • Ability to monitor and tune Java virtual machine and app servers; articulate JVM GC process and its logs; collect performance metrics from *nix and Windows;
  • Expertise in Agile and waterfall testing methodologies and tools such as Jira, Rally, Rational Team Concert, Quality Center, etc;
  • Experience in building the right performance environment data sets and use of data virtualization tools where required;
  • Self-motivated individual that crafts solutions and continuously learns new applications and technologies;
  • Strong interpersonal and problem-solving skills with phenomenal attention to detail, critical thinking, solid communication and proven leadership skills with the ability to lead multiple test paths simultaneously.

Nice to have

  • Performance tuning experience with RDBMS (Oracle, SQL Server, DB2, etc.) is a huge plus;
  • Application development expertise preferably in Java and test tools (i.e. Junit and JBehave);
  • Exposure to test and behavior-driven development (TDD and BDD).
