L1 Engineer - LTE / 5G

Job Description : Layer 1 (L1) Engineer (LTE / 5G PHY)

Location : Bengaluru, India

Experience Range : 2 - 9 years

We are looking for a highly motivated and skilled Layer 1 (L1) Engineer to join our team in Bengaluru. The ideal candidate will possess a strong foundational understanding and hands-on experience in wireless communication technologies, particularly the Physical Layer of LTE (4G) and 5G networks. This role is critical for the design, development, optimization, and testing of our cutting-edge eNodeB / gNB (base station) solutions, with a strong focus on Cloud-Native architectures.

Responsibilities

• Design and Development : Architect, design, and implement high-performance Physical Layer (PHY) algorithms and modules for LTE (4G) TDD and 5G NR base station (eNodeB / gNB) software stacks.
• Standards Compliance : Analyze, interpret, and implement functionalities strictly adhering to 3GPP LTE and 5G standards.
• Signal Processing : Develop and optimize advanced digital signal processing (DSP) algorithms relevant to the PHY layer, such as synchronization, channel estimation, equalization, MIMO processing, and coding / decoding.
• Performance Optimization : Conduct extensive performance tuning and multi-core processor optimization of L1 algorithms to meet strict real-time and throughput requirements.
• Cloud-Native Integration : Actively participate in integrating L1 components within Cloud-Native architectures and technologies (e.g., containers, microservices, Kubernetes).
• Testing and Validation : Develop unit tests, integrate L1 with higher layers (L2 / L3), and support system-level validation and field trials.
• Documentation : Create detailed design documents, test plans, and technical specifications.
• Collaboration : Work closely with cross-functional teams, including Systems Engineering, L2 / L3 Software Development, and QA, to ensure seamless integration and high product quality.
