Key Skills

Job Description

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.

Core Responsibilities

You will design and implement production-ready Java and Python libraries for identifier management and contribute to a resolver service for large-scale data platforms. The role involves creating machine-readable standards, defining versioning practices, and collaborating with domain teams to ensure robust identifier validation.

Requirements

The ideal candidate has strong production experience with both Java and Python and a background in building reusable SDKs or platform components. You must possess excellent API design skills and a solid understanding of distributed systems and service-oriented architecture.
