This role involves working with 5G/6G/NTN technology.
About the role
The Advanced Forward Deployment Engineer works inside a customer's development program as a software developer, systems engineer, and deployment lead, shipping production code. This role involves diagnosing issues deep within the protocol stack (Layer 1 to Layer 3) and modifying software for 5G/6G/NTN systems.
What you'll do
- Own technically complex deployment issues from first report to validated fix.
- Work onsite or closely with wireless customer development teams during major feature introductions.
- Analyze signaling flows, traces, timing behavior, and performance data to isolate failures.
- Write and modify application and protocol-stack software, plus supporting software and firmware.
- Develop and extend Python APIs that customer teams integrate against.
- Create diagnostic instrumentation when existing tools are insufficient.
- Develop, validate, and deploy controlled patches, feature flags, and interim releases.
What you'll need
- Strong software-development experience across multiple software stacks.
- Expertise in at least one domain (PHY/L1, MAC/RLC/PDCP and L2, or RRC/NAS and L3), plus working knowledge of adjacent layers and end-to-end 4G, 5G, and 5G-Advanced system behavior.
- Proficiency in C/C++ and Python (including API development), Linux, embedded or real-time software, and automated testing.
- Experience debugging protocol interactions through logs, traces, packet captures, call flows, and timing analysis.
- Familiarity with 3GPP specifications and the practical differences among standards compliance, interoperability, and implementation behavior.
- Experience in design and test instrumentation and test emulation tools.
- Ability to produce production-quality code that ships in a customer's build.
- Judgment and customer presence to operate inside confidential development programs.
- Willingness to relocate or travel to a specific customer site as required by the assignment.
