We are open to hiring in our Fleet (UK) and Milan (Italy offices) for this role.
Keysight is looking for a Wireless Protocol Software Engineer with strong 3GPP protocol expertise to develop robust software capabilities and APIs for system configuration, working close to standards and real implementations.
In this role, you will translate evolving 3GPP specifications into system‑level configurability, enabling reliable configuration and validation of protocol behavior across UE and base station emulation. You will contribute to early 6G pre‑standard implementation activities, partnering across disciplines to deliver high‑quality solutions.
This position sits at the intersection of protocol standards, software engineering, and system configuration APIs, within a multi‑site international environment.
Responsibilities
* Design, develop, integrate, and optimize APIs for system‑level configurability.
* Validate 3GPP protocol configurations, with specific focus on RRC configuration.
* Support both UE and base station emulation environments.
* Contribute to pre‑6G standards, following 3GPP evolution and emerging requirements.
* Convert evolving requirements (3GPP releases, operator acceptance needs, O‑RAN priorities) into:
* Clear software designs and interfaces
* Reusable and maintainable components
* Collaborate with cross‑functional experts (systems, RF, protocol, UI, customers/partners) to:
* Reproduce field issues
* Debug complex behaviors
* Deliver fixes with strong root‑cause discipline
Qualifications
* Strong expertise in 3GPP LTE / NR.
* Focus on API management and 3GPP protocols.
* Proficiency in C# / C++.
* Experience with RESTful API design, documentation, development, testing, and debugging.
* Experience using Swagger.
* Strong software development and debugging skills.
* Experience working in a multi‑site / distributed engineering environment.
* Ability to communicate technical concepts clearly in English, both written and verbal.
* Experience with CI/CD pipelines, automated test frameworks, containers, and/or cloud‑based deployment environments (preferred)
* Familiarity with tools such as Git, Valgrind/Polaris, and JIRA (preferred)
