System Architecture Lead, Direct-to-Device, Amazon Leo

Amazon LEO is building a Low Earth Orbit satellite constellation designed to provide connectivity to customers around the world.

We are looking for an experienced system architecture lead with end-to-end experience across the direct-to-device (D2D) satellite and cellular ecosystem. This role owns the end-to-end technical architecture of the D2D service, translating customer and business needs into a coherent system solution across core, RAN, satellite, devices, spectrum, regulatory, and service.

The ideal candidate has already architected real D2D, NTN, satellite-to-cellular, or closely related systems and understands how architecture decisions in one domain affect the others. This is not a role focused on a single engineering discipline. We are looking for someone who can define the complete system, drive cross-domain decisions and trade-offs, and keep the solution technically coherent as requirements, customer needs, and subsystem designs evolve.

The successful candidate will combine broad cellular and service knowledge with strong customer and partner skills, strong ownership, and the ability to lead in a fast-moving, international environment.

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.

Key job responsibilities

• Own the end-to-end D2D technical architecture and the technical plan of record.
• Translate customer, MNO, and business needs into the system architecture, working closely with Business, Product, and Solutions Architecture.
• Drive cross-domain architecture decisions and trade-offs across core, RAN, satellite payload, devices, spectrum, regulatory, and service, and document their rationale.
• Assess technical feasibility of proposed solutions and support customer and MNO engagements, so that commitments are clear, achievable, and aligned with system capabilities.
• Partner with Systems Engineering to turn the architecture into requirements, interfaces, and acceptance criteria that Development can build and test against.
• Maintain end-to-end technical coherence as requirements, customer needs, and subsystem designs evolve, and resolve cross-domain conflicts between development teams.
• Bring ecosystem requirements and findings (MNO, OEM, chipset) back into the architecture, working with Telco Service Development.
• Define the evolution path of the architecture, including new features, markets, device categories, and next-generation satellites.
• Act as the subject matter expert for the end-to-end D2D architecture, and represent the architecture with leadership, customers, partners, and vendors.
• Work effectively across geographically distributed, international and multicultural engineering, business, and customer organizations.
