Sr. Software Engineer (Java & Python)

We are looking for a Senior Software Engineer to join a high-impact platform initiative focused on creating a scalable, machine-readable identifier standard across a large data ecosystem. The objective is to eliminate inconsistencies between systems by introducing a shared approach to generating, validating, parsing, and resolving identifiers.

You will play a key role in building production-ready URN libraries in both Java and Python and contribute to a resolver service that enables identifier mapping across services and domains.

Responsibilities

• Design and develop equivalent Java and Python SDKs/libraries.
• Build support for canonical, extension, nested, and composite identifiers.
• Implement robust parsing, validation, and error-handling mechanisms.
• Create and maintain a catalog-driven model for identifier definitions and validation rules.
• Define versioning, backward compatibility, and release management practices.
• Develop automated test suites and CI/CD quality controls.
• Produce clear technical documentation and developer guidance.
• Collaborate with architects and domain teams to drive adoption of identifier standards.
• Contribute to resolver service APIs and mapping logic between identifier types.
• Lead technical delivery from design through MVP and production stabilization.

Required Skills

• Extensive hands-on experience with Java and Python in production environments.
• Strong background in SDK, library, or platform component development.
• Excellent API design and software engineering practices.
• Experience with parsing, validation frameworks, and testing methodologies.
• Understanding of distributed systems and service-oriented architectures.
• Knowledge of metadata management, schemas, identity systems, catalogs, or resource naming standards.
• Strong stakeholder communication and collaboration skills.

Preferred Experience

• Kafka or event-streaming technologies.
• OpenLineage, data lineage, metadata management, knowledge graphs, or data catalog platforms.
• Experience publishing and maintaining multi-language packages and developer tooling.

Details

• Start: Asap
• Duration: 6 months (+)
• Location: Amsterdam, hybrid
