CAPCO POLAND - WARSAW

*We are looking for Poland based candidate. 

At Capco Poland, we’re not just another consultancy - we’re the spark behind digital transformation in the financial world. As a global leader in technology and management consulting, we thrive on helping clients tackle the toughest challenges across banking, payments, capital markets, wealth, and asset management.

Role Overview

We are seeking React / Java Full Stack Engineer to join our Global Asset Servicing Platform team. This is a hands-on engineering role where you will design, build, and test features end-to-end – with full ownership of code and quality. 

You will work across development and test automation: coding new functionality, writing unit and integration tests, and adding Cucumber-based end-to-end tests – not only for your own work but also for features built by your teammates, to ensure unbiased validation.

The ideal candidate will be skilled in Java backend development and modern UI development using React. This role will work across the full stack to build a scalable, reliable, and user-friendly application.

Key Responsibilities

  • Design, develop, and maintain features using Java and React.
  • Build responsive and modern frontend applications using ReactJS,
  • Develop and integrate APIs and web services.
  • Experience working with relational databases (Oracle, Postgres)
  • Write clean, well-structured unit tests (JUnit or equivalent) alongside your code.
  • Contribute to and maintain our automated test framework using Ruby and Cucumber:
    • Write new Ruby step definitions as needed.
    • Create and maintain Cucumber feature files for end-to-end testing.
  • Write automated tests for features developed by other engineers, ensuring high-quality outcomes and reducing development bias.
  • Champion a test-first approach, delivering code that is reliable, maintainable, and scalable.
  • Apply performance and scalability considerations; use tools such as JMeter for load/performance testing where required.
  • Ensure instrumentation, configuration, and logging are embedded in code to support ongoing monitoring and support.
  • Analyse and debug issues using logs; propose and implement fixes.
  • Collaborate in Agile ceremonies, helping the squad plan effectively and commit to clear sprint goals.
  • Partner with product managers and analysts to understand what is being built, why it matters, and how best to implement it for both functional and non-functional needs.
  • Build with a product mindset – appreciating client impact, configurability, and long-term supportability.

Skills & Experience

    • Java (with strong JUnit testing experience)
    • React (with associated unit testing frameworks)
  • Familiarity with automation frameworks & languages:
    • Ruby scripting for step definitions

  • Strong understanding of:
    • Multi-threading, parallel processing, and real-time messaging
    • Test-first design, CI/CD practices
  • Ability to use JMeter or similar tools for performance testing (a plus)
  • Basic understanding of cloud services: databases, servers, storage, gateways (not at architect level, but practical awareness of hosting environments).
  • Experience using AI-assisted engineering tools (such as GitHub Copilot, ChatGPT, or similar) to accelerate coding, testing, debugging, and documentation, while maintaining code quality and critical thinking.

Functional / Domain Knowledge

  • Familiarity with financial markets concepts.
  • Knowledge of corporate actions lifecycle preferred.

Soft Skills

  • Strong analytical and debugging abilities.

  • Curious and thoughtful: able to look beyond the ticket to understand requirements, impact, and broader context.
  • Product mindset — balancing immediate delivery with long-term maintainability and client impact.

B2B cooperation in a hybrid model, with the option to provide services from the Warsaw office to the extent agreed based on project needs.
