Java Developer with Apache Flink (EMEA)

We are looking for 3 Software Development Engineers (Java) to join a managed service engagement supporting a large-scale data and analytics ecosystem. The team will contribute to an open-source table format project widely used in distributed data processing systems, with the goal of improving interoperability with a major cloud-based data lake service. The initial scope includes enhancing stream processing engine support for the latest table format specification, improving compatibility between cloud-native lakehouse capabilities and open-source tooling, addressing authentication inconsistencies in OSS integrations, implementing already-approved specification features, and closing functional gaps between specification and tooling behavior.

Tasks

• Contribute to open-source development related to distributed data table format specifications and ecosystem tooling;
• Improve stream processing engine support to align with the latest table format specification version;

• Identify and address authentication and authorization gaps in OSS integrations, especially related to cloud identity mechanisms;
• Implement community-approved specification features that are not yet available in current implementations;
• Analyze and close behavioral gaps between formal specifications and real-world tooling implementations;
• Collaborate with distributed teams and contribute code, design discussions, and reviews within the open-source community;
• Ensure production-grade quality, maintainability, and performance of contributed components.

Requirements

• 3+ years of experience as a Software Development Engineer with strong Java expertise;
• Solid experience working with distributed data systems and large-scale data processing frameworks;
• Experinence with GCP and its services;
• Hands-on experience with Apache Iceberg AND/OR Apache Flink;
• Strong understanding of cloud environments and authentication mechanisms in distributed systems;
