Overview

This role develops an open-source MVP of a spectrum-rights registry and authorization service, including system architecture, API, data schemas, simple GUI, SDR test, and learning documentation across two phases of prototyping.

Tasks Summary

• Design the overall system architecture for the spectrum-rights registry, including data models, identity assumptions, authorization logic, and audit logging.
• Define machine-readable spectrum-rights objects covering frequency range, geography, time window, and basic constraints.
• Design a modular architecture that can accommodate future extensions.
• Implement the MVP backend service supporting creation, update, and revocation of spectrum-rights objects, authorization checks, and structured logging.
• Develop a minimal web-based graphical interface for regulators and operators.
• Develop a software-defined radio (SDR) test harness or equivalent simulation.
• Publish all code in a public GitHub repository with clear documentation and version control.
• Provide technical explanations and diagrams to support engagement with regulators.
• Translate regulator questions and feedback into concrete system refinements.
• Support the design of safe, regulator-approved test scenarios.
• Support at least one laboratory or field-based sandbox test using the MVP.
• Evaluate system behavior, limitations, and usability.
• Propose refinements and architectural improvements.
• Document architectural options for future phases.
• Produce clear technical documentation to inform future decision-making.

Experience Requirements

• A minimum of 7 years of experience in software engineering, system architecture, or distributed systems is required.
• Experience in designing and delivering complex technical systems is required.
• Experience in backend services, APIs, and data modeling is required.
• Proven record of producing and maintaining open-source software is required.

Qualification Requirements

• An advanced University Degree (Master’s degree or equivalent) preferably in mathematics, computer science, IT, engineering or a related field is required.
• A first level University Degree (Bachelor`s degree or equivalent) preferably in the above-mentioned areas or in a relevant field combined with 2 additional years of professional experience may be accepted in lieu of the Advanced University Degree.
