GNC Engineer, ADCS (Starlink)

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.GNC ENGINEER, ADCS (STARLINK)SpaceX is looking for engineers with backgrounds in orbital mechanics, control theory, state estimation, spacecraft systems design, optimization, physics, and software development to join the Starlink guidance, navigation, and control (GNC) team. Come help us write the autopilot algorithms for thousands of satellites (the world's largest constellation!) and more than two million user terminals, enabling access to high-speed broadband internet in all corners of the world.As a Guidance, Navigation, and Control (GNC) engineer on Starlink’s attitude determination and control systems (ADCS) team, you will be responsible for the software automation, operations, and system level design which keeps the satellites and their payloads properly oriented for the entire mission lifetime.RESPONSIBILITIES:Develop highly reliable and performant GNC algorithms, simulations, tools, services, and dashboards using C++ or Python; Starlink GNC Engineers write actual production code, not just prototypes for transcription by another teamParticipate in architecture, design, and code reviewsBulk data analysis to review performance data from various elements of the Starlink constellation and networkWrite high quality technical documentation of programs, algorithms, or analysisDesign and implementation of GNC software that can facilitate all mission concepts of operations across all phases of mission, including off-nominal/contingency scenariosDesign of concepts of operations (CONOPs) that intelligently balance thermal constraints, power budgets, momentum management, communications, and payload-pointing needsDesign, development, and flight software implementation of onboard GNC algorithms to achieve a high level of vehicle autonomy and fault tolerance while providing adequate translational and rotational navigation and control performanceUpdate and maintain GNC software configurations for a variety of minor vehicle design revisions and mission setsHigh fidelity time domain 6DOF modeling and simulation of vehicle dynamics, sensors, actuators, algorithms, and all of their interactionsMonte Carlo simulation analysis to validate safe and reliable flight and quantify navigation and control performanceHeavy involvement in hardware-in-the-loop (HITL) testing efforts, including but not limited to test case design, data review automation, and modeling fidelity improvementsTranslational and Rotational state estimation and control systems design and optimizationVehicle design activities related to ADCS sensor and actuator hardware sizing and layoutDevelop, validate, and improve upon complex sensor, actuator, and dynamics models for use in 6DOF simulation analysisMaintain tight interfaces with other disciplines and subsystems (e.g. thermal, power, communications) to ensure a good and consistent system-level designSupport your relevant on-call operations rotation, commanding satellites or reviewing network data to keep our network continuously operating at peak performanceBASIC QUALIFICATIONS:Bachelor's degree in computer science, aerospace, physics or an engineering disciplineSoftware development experience in either C++ or PythonPREFERRED SKILLS AND EXPERIENCE:Some preferred skills and experience depend on the specific team within Starlink GNC.Master's degree or PHD in an engineering discipline or physicsDeveloped, debugged and deployed software that has been used in real world applications/projectsCreative approach to problem solving, exceptional analytical skills and engineering fundamentalsCradle to grave development of three axis stabilized spacecraft incorporating momentum, magnetic, and propulsive controlStrong understanding of orbital mechanics, including low thrust trajectory optimization and stationkeepingExperience in verifying GNC algorithm performance via simulation, and validation of the simulation's modelsExperience with state estimation, particularly attitude determination, orbit determination, GNSS, and radio navigationGeneral familiarity with the disciplines necessary for spacecraft flight including; structures, propulsion, avionics, GNC, flight software, dynamics, launch and mission operations, and integration. Practical experience in real world development of these systems is highly desiredCapable of identifying and solving complex problems with little to no supervision or directionPassion for advancing the commercial space industryAbility to work in a fast-paced, autonomously driven, and demanding start-up atmosphereExcellent communication skills both written and verbalCOMPENSATION AND BENEFITS: Pay Range: Level 1: $125,000.00 - $165,000.00Level 2: $145,000.00 - $200,000.00Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short and long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation and will be eligible for 10 or more paid holidays per year. Employees in Washington State accrue paid sick time in compliance with state and federal law. Company shuttles are offered to employees for roundtrip travel from select Seattle locations to the SpaceX Redmond office Monday to Friday.ITAR REQUIREMENTS:To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
