Cellular Protocols Researcher

About the role
We conduct careful, small-scale studies of LTE/5G protocol behavior with a focus on access and signaling. The work follows a scholarly rhythm: pose a precise question, design a minimal experiment, gather the necessary traces, and produce a clear research note with enough detail for reproduction. Projects are modest in scope, cumulative in impact, and documented with care. You’ll own studies end-to-end and contribute to a tidy internal corpus of methods, observations, and lightweight tools.

Typical activities

1. Formulate testable questions around registration, mobility, paging, and related procedures.
2. Configure compact lab setups (or emulation) to run short, controlled experiments.
3. Capture and interpret RRC/NAS and selected L2/L3 artifacts; compare behaviors across conditions.
4. Write concise research notes with methodology, observations, and a minimal reproduction package (script/pcap).Maintain well-organized lab notebooks and a small library of reusable helpers.

Requirements

1. Foundation in LTE/NR concepts (control plane, state transitions, basic L2/L3).
2. Comfort working in Linux and writing small scripts for parsing and automation.
3. Clear technical writing and an orderly approach to documenting methods and results.

Desirable background 

1. Time with open stacks or testbeds (e.g., srsRAN, OAI) or common RF/test tools.
2. Familiarity with reading 3GPP materials and basic node configuration.
3. Experience designing small experiments or curating trace datasets.
