We are building a next-generation Investment Reporting platform from scratch (Greenfield). We are looking for a highly experienced Java Engineer to design and develop this brand-new solution. Rather than doing a direct translation or legacy maintenance, our goal is to build a completely new architecture. The existing system will serve purely as a functional reference point to help us understand and capture complex business rules during the design phase.

Senior Java Developer

Why this Role is Compelling:

  • 100% Greenfield Development: Your focus is entirely on creating a brand-new application using modern Java technologies.
  • Collaborative Architecture: Work hand-in-hand with dedicated Architects, contributing your expertise to shape the backend services, APIs, and system integration.
  • Domain Expertise: Gain deep exposure to the investment banking domain by transforming established business capabilities into a modern, high-performance platform.

Key Responsibilities:

  • Backend-First Development: Design and build scalable Java backend services and ensure seamless integration with the frontend.
  • Functional Alignment: Analyze existing business capabilities to ensure the new greenfield platform delivers comprehensive functionality while keeping the code clean and optimized.
  • Data Layer Integration: Work with enterprise databases to optimize data processing and ensure consistency as the new platform is rolled out.
  • Technical Collaboration: Partner with architects and tech leads to ensure that development aligns perfectly with modern best practices and the targeted system architecture.

Requirements:

  • Enterprise-Level Java: Robust experience in building scalable backend applications (Spring Boot).
  • Solid SQL Skills: Proficiency in relational databases (Sybase and/or Oracle), including analyzing and optimizing data structures and queries.
  • Analytical & Adaptable Mindset: Openness to explore and understand the logic of the existing system (built on 4D) to extract core business rules.
  • Fluent English: Required for daily collaboration within our international team.
  • Nice to Have:
    • Angular Experience: Familiarity with developing Single Page Applications (SPA) and frontend state management.
    • Experience participating in system modernization or platform transformation projects.
    • Familiarity with reporting frameworks (e.g., Jasper Reports).

What we offer:

  • Hybrid work mode, 50% working from home within a month
  • Equivalent for remote work expenses (120 PLN per month)
  • Stable employment in the international company
  • Fully paid private medical care for employee
  • Pre-paid lunch card
