Leo is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world. Leo will help close the digital divide by delivering fast, affordable broadband to a wide range of customers, including consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity.

This role is for a Software Engineer who will design, implement, and operate globally distributed systems that enable Leo to achieve low single-digit-second query responses within a near real-time analytics layer or lakehouse, and to support agentic AI capabilities on top. You’ll build these systems using the latest AWS technologies and best-in-industry software engineering practices.

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
Architect and implement a scalable, cost-optimized S3-based Data Lakehouse that unifies structured and unstructured data from disparate sources.
Architect and implement a scalable, cost-performance-optimized OLAP-based analytics layer
Establish metadata management with automated data classification and lineage tracking.
Design and enforce standardized data ingestion patterns with built-in quality controls and validation gates.
Architect a centralized metrics repository that becomes the source of truth for all Leo metrics.
Implement robust data quality frameworks with staging-first policies and automated validation pipelines.
Design extensible metrics schemas that support complex analytical queries while optimizing for AI retrieval patterns.
Develop intelligent orchestration for metrics generation workflows with comprehensive audit trails.
Lead the design of semantic data models that balance analytical performance with AI retrieval requirements.
Implement cross-domain federated query capabilities with sophisticated query optimization techniques.
Architect a globally distributed vector database infrastructure capable of managing billions of embeddings with consistent sub-100ms retrieval times.
Design and implement hybrid search strategies combining dense vectors with sparse representations for optimal semantic retrieval.
Establish automated compliance validation frameworks ensuring data handling meets Amazon's security standards.


A day in the life
This role is for a Software Development Engineer who will build new cloud services and APIs that facilitates and orchestrates simulation of software on Leo devices such as satellites, ground gateways, and customer terminals. You will be building low-latency, highly scalable architecture that are critical to getting high quality internet service to customers.
