Amazon Leo is building the world's most advanced low Earth orbit (LEO) satellite constellation to deliver high-speed, low-latency broadband connectivity to unserved and underserved communities around the globe. As part of this mission, we are seeking a Senior Manager to lead the design, development, and lab integration of real‑time communications software enabling robust, standards‑compliant connectivity between gNodeB platforms and Multi‑Operator Core Network (MOCN) environments.

Export Control Requirement:
Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

• 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 3
  
  GPP‑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 3
  
  GPP releases, industry trends, and evolving MOCN deployment models to guide long‑term product strategy aligned with Amazon Leo's roadmap.

• 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.

• 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.
• Identify and develop future technical leaders within the team, creating pathways for promotion and increased scope.
• Conduct regular 1:1s focused on career development, skill gap analysis, and stretch assignments that accelerate engineer growth.
• 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.

• Own the technical roadmap and execution plan, driving delivery across multiple work streams 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…
