• Role: Layer Engineer
• Location: Pune/Bangalore
• Experience: 7 to 15 Years
• Job Type: Full Time Employment

What You'll Do:

• Design, develop, and optimize MAC scheduling algorithms for LTE eNB, small cells, and 5G gNB systems.
• Implement scheduling strategies to meet performance demands in highlatency and dynamically changing environments.
• Work on MUE Scheduler, data path optimization, and contribute to enhancements across 3GPP protocol layers (MAC, RLC, PDCP, RRC).
• Collaborate with system engineering teams to understand architecture, design requirements, and endtoend system behavior.
• Analyze fieldreported issues, interact with crossfunctional teams to identify root causes, and provide technical resolutions.
• Design and debug L2 solutions with strong understanding of interfaces between L1 (Physical Layer) and L3 layers.
• Support RRC-related workflows including message sequencing for connection setup, mobility, and session management.
• Perform log analysis using advanced debugging tools and provide detailed reports on system performance and failures.
• Utilize specialized tools (e.g., QCAT, Viavi) for network characterization, performance validation, and troubleshooting

Expertise You'll Bring:

• MAC Scheduler Expertise: Strong understanding of MAC scheduling algorithms, including design, development, optimization, and debugging.
• Base Station Scheduling Experience: Handson experience with MAC scheduling on LTE eNB, small cells, or 5G gNB platforms.
• HighLatency & Dynamic Environment Handling: Proven ability to develop scheduling mechanisms suitable for varying and complex network conditions.
• 3GPP Protocol Knowledge: Expertise in MUE Scheduler, data path, and 3GPP layers MAC, RLC, PDCP, RRC.
• Systems Engineering Perspective: Experience working across system design and implementation activities with a holistic view.
• Customer Support (R&D): Ability to analyze realworld field issues, coordinate with engineering teams, and drive issue resolution.
• Programming & Architecture:
• Strong proficiency in C/C++, including coding, design, debugging, and architectural understanding.
• Solid knowledge of L2L1 and L2L3 interactions.
• RRC Message Flow Expertise: Familiarity with RRC message sequences involved in connection establishment, mobility, and configuration.

Benefits:

• Competitive salary and benefits package
• Culture focused on talent development with quarterly growth opportunities and company-sponsored higher education and certifications
• Opportunity to work with cutting-edge technologies
• Employee engagement initiatives such as project parties, flexible work hours, and Long Service awards
• Annual health check-ups
• Insurance coverage: group term life, personal accident, and Mediclaim hospitalization for self, spouse, two children, and parents
