RAN L3 Protocol Engineer (LTE/5G)

Amantya Technologies; Gurugram District, Bengaluru; On-site; INR 1,800,000 - 3,000,000; Full time

Job summary

Amantya Technologies is hiring a RAN L3 Protocol Engineer (LTE/5G) to design and implement control-plane features across LTE and NR. You will work on mobility and signaling, interfacing with AMF/MME and core network nodes using C/C++ and Python for robust interop.

Experience with RRC, S1AP/X2AP/NGAP, ASN.1 decoding, and data-plane tools like GTPU, DPDK and VPP is highly valued.

Qualifications

• Experience with LTE/NR control-plane features and signaling.
• Strong programming skills in C/C++ and Python.
• Familiarity with RRC and core-network interfaces (AMF/MME).

Responsibilities

• Design and implement RRC/ S1AP/X2AP/ NGAP/F1AP/E1AP/XnAP and higher-layer control-plane features for LTE and NR.
• Expertise in mobility control, measurement control & configuration, bearer/session signaling and related procedures.
• Knowledge of control-plane interfaces including S1AP/X2AP for LTE and NGAP/F1AP/E1AP/XnAP for 5G architectures with AMF/MME.
• Programming: C/C++/Python, memory pooling, state machine design, debugging and interoperability across UE/chipset/vendor combos.
• L3 data path expertise - GTPU, DPDK & VPP.
• Understand core RAN elements (eNB/gNB) and interfaces toward the core network.
