Our mission is to bridge the digital divide by delivering high-speed, low latency, internet services to underserved and unserved communities and remote communities around the world. By leveraging innovative satellite technology, we are working towards a future where everyone has access to reliable and high-quality internet connectivity regardless of their location. Amazon Leo for Government (ALG) Engineering is a multi-disciplinary technology team established to rapidly address the needs of targeted government, enterprise, and international customers for both space-based and terrestrial applications. ALG Engineering collaborates closely with Amazon Leo to leverage the constellation in providing seamless and efficient communication capabilities to meet the needs of our targeted customers. The Systems Engineering, Integration, Test, and Manufacturing organization under ALG Engineering plays a vital role in the entire life cycle of the development of an engineering solution, including architecture development, requirements and interface definition through assembly, integration, and test (AI&T). verification, and post-delivery and operational support. As a member of the SEIT | MFG organization, the Guidance, Navigation, and Control (GNC) System Engineer will be responsible for developing system architecture, defining requirements and interfaces, and executing the design, build, integration, test, and verification of space-based and terrestrial GNC subsystems. The candidate will have a background in dynamics, control theory, state estimation, optimization, and have experience with space vehicle communication payloads (RF antennas, optical inter-satellite links). The candidate will have the capability to design algorithms, model dynamics, author both simulation and flight software, perform integration & test, verify requirements and validate on-orbit performance., * Define requirements and interfaces, design, integrate, test, and verify GNC subsystems for space and terrestrial applications * Design and implement production-quality GNC algorithms and architectures * Create and maintain high quality GNC subsystem technical documentation of programs, algorithms, and analysis as well as engineering artifacts for drawings, code, and use cases * Participate in code reviews, debugging, and the refactoring of production software with an emphasis on the continuous improvement of code that is organized, structured, documented, maintainable and reusable for similar applications * Collaborate with mechanical designers to develop and test electro-mechanical and electro-optical subsystems * Produce/support review of GNC subsystem integration & test plans, procedures, test scripts, and calibration routines * Perform analysis on data generated from test campaigns and on-orbit/mission operations, and communicate issues effectively with developers and managers Security Clearance : This position requires that the candidate selected be a US Citizen and candidates must be able to obtain and maintain a US Government security clearance of TS/SCI.
