Senior Manager, 5G RAN – Core Systems Software Architecture

Technical Leadership & Architecture

• Architect and design the full software stack enabling real-time control-plane and data-plane communication between gNodeB and MOCN environments in support of Amazon Leo's satellite-terrestrial integration objectives.
• Define software partitioning, module boundaries, and interface specifications for NGC, NGU, RRC, and Multi-PLMN broadcast components.
• Lead development of 3GPP-compliant protocol layers, ensuring deterministic behavior, low latency, and high reliability for satellite-based connectivity.
• Oversee integration of transport technologies, including MPLS and segment routing, into the RAN-Core connectivity architecture.
• Drive troubleshooting and performance optimization across NGC, NGU, and RRC layers.
• Author technical specifications, architecture documents, and interface control documents (ICDs) for internal and external stakeholders.
• Stay current with 3GPP releases, industry trends, and evolving MOCN deployment models to guide long-term product strategy aligned with Amazon Leo's roadmap.

Lab Integration & Hardware-in-the-Loop Testing

• Lead lab activities including Hardware-in-the-Loop (HIL) test framework development, physical interface validation, and system-level integration testing.
• Develop and validate HIL test frameworks ensuring accurate modeling of physical interfaces, fronthaul/backhaul connectivity, and multi-operator core interactions.
• Oversee lab infrastructure planning, equipment procurement, and test environment configuration to support rapid prototyping and validation cycles.
• Drive lab-based integration of RAN, transport, and core network components, ensuring end-to-end system alignment and standards compliance.
• Collaborate with RF, RAN, and Core engineering teams in the lab to validate satellite-terrestrial network interoperability.

Team Building & People Development

• Build and scale a high-performing software engineering team through strategic hiring, including conducting phone screens, on-site interviews, and bar raiser activities.
• Develop individual growth plans for each engineer, identifying technical and leadership development opportunities aligned with career aspirations.
• Mentor engineers at all levels, providing regular coaching on technical depth, system design thinking, and Amazon's Leadership Principles.
• Foster a culture of continuous learning through technical brown bags, design reviews, code reviews, and knowledge-sharing sessions.
• Create an inclusive team environment that encourages innovation, calculated risk-taking, and learning from failure.
• Drive organizational health metrics including retention, engagement, and internal mobility.

Program Execution & Amazon Leadership

• Own the technical roadmap and execution plan, driving delivery across multiple workstreams with high standards and operational excellence.
• Operate with a bias for action while maintaining the highest bar for quality and safety in satellite communications systems.
• Write and present technical documents (6-pagers, PR/FAQs, design documents) to senior leadership.
• Collaborate cross-functionally with hardware, systems, operations, and program management teams across Amazon Leo.
• Demonstrate Ownership by treating the team's mission as your own, and Earn Trust through transparent communication and consistent delivery.
