Java Developer

Our client’s development team is looking for a talented Java Developer to join our team, working on an industry-leading trading platform. We work in a collaborative, innovative, and technically challenging environment, where developers can perform complex software design tasks and technical analysis on a highly performant, multi-threaded and resilient system, where high performance is key.

Specifically, this role is part of our client’s application performance team whose focus is to identify the performance bottlenecks at the code level, suggest fixes/design changes, tuning and improvements. This team develops the code for simulating user scenarios, custom tooling, creating mock services and maintenance of the tool repository. The ideal candidate is a problem-solver with great analytical ability, having the desire to get their hands on design and development.

In addition, understanding the theory behind performance testing and key performance metrics will also be critical. Role would involve working across the full stack – native client-side performance as well the Mobile & Services Gateways that backs our native client applications – and collaborate with the Performance QA team to manage the environments and tooling. You will also interact closely with our product partners, support teams, and other technical leaders.

Responsibilities:

• Work with the Performance QA team on test runs to stress the capabilities of the system and identify bottlenecks at the code level.
• Develop an understanding of architecture to identify unique solutions to provide the best client experience in a scalable way.
• Identify and collect key performance metrics for the system.
• Address both client and server-side performance and suggest performance enhancements and tuning.
• Provide solutions for production side monitoring.
• Establish a performance & scalability roadmap, execute & communicate updates to stakeholders.
• Ability to quickly adapt to changing environment, understand the complex code base quickly and be able to work within ambiguous design constraints.
• Highly motivated, self-starting individual who can take effective independent decisions.
• Excellent analytical and problem-solving skills. Provides analysis of problems, evaluate alternatives, and provides solutions that are consistent with business objectives and strategy.
• Understand the role of hardware in both production and performance environments and help manage those environments.

Experience:

• Have knowledge of professional software engineering practices, best practices for the full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations.
• Have excellent coding skills in a distributed Java environment.
• 5+ years of Java, J2EE (client and server side), Spring framework, Spring Boot, and Spring cloud.

• Strong experience with concurrency & multi-threading.
• Understanding of data structures, algorithms, and design patterns (GoF). Experience with troubleshooting/diagnosing JVM issues (e.g. thread dumps, garbage collection, and memory management).
• Experience with resiliency implementations – Circuit Breakers, Shapers, Load Balancers & Failover.
• Strong analytical, organizational and problem-solving/decision-making skills.
• Dev Ops and build automation experience. Proven ability to work effectively in a team setting as well as independently with minimal error and guidance.
• Outstanding verbal and written communication skills.
• Understanding of performance best practices, performance key metrics, and statistics.
• Experience in the Financial Services industry is strongly preferred.
• Must be very detail-oriented.
