You will be responsible for developing the critical Pointing, Acquisition, and Tracking (PAT) software that enables our constellation to communicate. Given the groundbreaking nature of this technology, your work will begin in a high-fidelity simulation environment, where you will design, prototype, and validate the complex algorithms required to establish and maintain optical links between multiple satellites. This is a role for a senior engineer who thrives on solving new problems and is excited to build the software for a system that has never been built at this scale. Responsibilities include but are not limited to: * Design, develop, and implement the flight software for the Pointing, Acquisition, and Tracking (PAT) of our Optical Intersatellite Links (OISL). * Create and maintain high-fidelity simulations to model the performance of the OISL PAT system in a dynamic, multi-satellite environment. * Develop and verify the complex control algorithms required to accurately point and track optical terminals across vast distances. * Implement the software interfaces between the OISL PAT system, the flight computer, and the optical hardware. * Analyze simulation and test data to validate system performance, identify anomalies, and drive design improvements. * Collaborate closely with optical engineers, GNC specialists, and systems engineers to ensure the PAT software meets the demanding performance requirements of the network. * Contribute to the full lifecycle of the OISL software, from early simulation and prototyping to hardware-in-the-loop testing and on-orbit commissioning., Applicants for employment at Blue Origin 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. Background Check * Required for all positions: Blue's Standard Background Check * Required for Certain Job Profiles: Defense Biometric Identification System (DBIDS) background check if at any time the role requires one to be on a military installation * Required for Certain Job Profiles: Drivers who operate Commercial Motor Vehicles with a Gross Vehicle Weight (GVW), Gross Vehicle Weight Rating (GVWR) or combination of power unit and trailer that meets or exceeds 10,001 lbs. and/or transports placardable amounts of hazardous materials by ground in any vehicle on a public road while in commerce, may be subject to additional Federal Motor Carrier Safety Regulations including: Driver Qualification Files, Medical Certification (obtained before onboarding), Road Test, Hours of Service, Drug and Alcohol Testing, vehicle inspection requirements, CDL requirements (if applicable) and hazardous materials transportation/shipping training. * Required for certain Job Profiles: Ability to obtain and maintain Merchant Mariner Credential, which includes pre-employment and random drug testing as well as DOT physical
