The platform is mature and feature-rich, and we are continuously extending it with new capabilities, improving performance, and refining the experience for a demanding global user base. You will contribute to a Java-based product that our customers rely on in real time.
What will be your responsibilities within IBKR:
  • Design, develop, and maintain features across the trading application, with a primary focus on the Java business layer.
  • Integrate with backend services over REST, WebSockets, and FIX to deliver responsive, reliable functionality to end users.
  • Participate in the full software development lifecycle, including design, implementation, unit testing, code review, and ongoing maintenance of the features you deliver.
  • Collaborate with business analysts, product managers, and other developers to translate requirements into high-quality software.
  • Write and maintain clear technical documentation for the code and designs you produce.
  • Investigate and resolve complex technical issues across the stack.
  • Stay current with relevant tools, libraries, and techniques that can improve the platform.

Skills Required:

  • Strong proficiency in Java, with a deep understanding of object-oriented programming and software design patterns.
  • Solid software development fundamentals, including writing clean, maintainable, well-tested code and producing clear documentation.
  • Working knowledge of multithreading and concurrency, with an appreciation for lean, low-latency programming.
  • Proficiency with Git for source control and collaborative development.
  • Strong analytical and problem-solving skills, with the ability to troubleshoot complex technical issues across a large codebase.
  • Excellent verbal and written communication skills.

To be successful in this position, you should be:
  • Experience with declarative, state-driven UI frameworks (React Native, Flutter, QML, etc.); prior Qt/QML experience is a plus, but genuine interest in learning it is equally valued.

  • Exposure to Linux as a development or deployment environment.
  • Working familiarity with Gradle as a build automation tool.
  • Awareness of AI-assisted development tools such as Claude Code and other agentic coding tools.
  • Comfortable working within an established codebase, following existing architectural patterns, team conventions, and development protocols.
  • Able to ramp up quickly on a mature platform and deliver incremental value while respecting existing design decisions.
  • Flexible and pragmatic, with the judgment to know when to follow precedent and when to raise a well-reasoned alternative.
  • Self-motivated and able to handle tasks with minimal supervision in a fast-paced team.
  • High-ownership mindset, taking features from design through delivery and standing behind their quality.
  • Outstanding organizational and time management skills.
