Solid Python skills , an eye for system interfaces , and a drive to build resilient integration layers are essential as you contribute to the backbone of cross-domain development workflows.

Key Responsibilities #

Develop and maintain Python-based connectors for integrating a wide range of third-party systems into our traceability engine ubConnect .
Work extensively with external REST APIs , import/export interfaces, and custom protocols to enable seamless toolchain integration.
Implement support for industry-standard formats such as ReqIF , JSON , XML , and YAML , ensuring data consistency and interoperability across systems.
Enable automated synchronization of requirements, test data, and implementation artifacts across ALM, PLM, and test management tools.
Collaborate with cross-functional teams to align connector architecture with related components like ubCode and ubTrace .
Ensure testability , robustness , and maintainability of integration components through systematic testing and quality-focused development practices.
Monitor and maintain integration workflows in safety-critical environments, contributing to reliability and compliance (e.g., ISO 26262 , TISAX ).
Analyze and adapt to evolving third-party system interfaces and APIs to keep integrations up-to-date and future-proof.
Maintain a stable CI environment for automated testing against locally hosted instances of external systems.
