Senior Software Engineer (For independent contractors)

We are seeking a senior software engineer consultant to build production-ready URN libraries in Java and Python, and contribute to the resolver service that maps identifiers across a large-scale data platform.

Different systems often represent the same entity using inconsistent identifiers. This creates ambiguity, duplicated mapping logic, brittle integrations, and unnecessary maintenance.

You will help create a shared, machine-readable identifier standard and developer library that enables teams to generate, parse, validate, and safely evolve identifiers across services.

What You’ll Do

• Design and implement equivalent Java and Python library APIs.
• Support canonical, extension, and nested/composite identifiers.
• Implement robust parsing, validation, and actionable error handling.
• Create a maintainable catalog-driven model for identifier types and validation rules.
• Define compatibility, versioning, and release practices.
• Build comprehensive automated tests and CI quality checks.
• Publish clear documentation, examples, and adoption guidance.
• Collaborate with architects and domain teams to onboard initial identifier types.
• Contribute to resolver-service APIs and logic for mapping between canonical and extension identifiers when external lookup is required.
• Work independently from design through MVP delivery and stabilization.

What We’re Looking For

• Strong production experience with both Java and Python.
• Experience building reusable libraries, SDKs, or platform components.
• Excellent API design, parsing, validation, and testing skills.
• Understanding of distributed systems and service-oriented architecture.
• Experience with schemas, catalogs, metadata, resource naming, or identity systems.
• Strong communication skills and comfort working across teams.

Nice to have

• Kafka or event-streaming experience.
• OpenLineage, data lineage, metadata, knowledge graph, or data catalog experience.
• Experience publishing and maintaining multi-language packages.
