Amazon Leo's Propulsion team designs, tests and builds its own propulsion systems - enabling current and future missions to serve customers. The Lead Electric Propulsion Engineer will provide technical leadership within Amazon Leo's Propulsion Design Engineering team as a subject matter expert for the electric propulsion system. This position demands a combination of technical depth, leadership abilities, and systems engineering experience capable of driving innovation of spacecraft propulsion technologies that ultimately enable customer service via the Amazon Leo satellite constellation. In this role, you will advise test, manufacturing, and mechanical engineers on electric propulsion best practices. Your expertise will directly influence all aspects of propulsion system design and development, including propellant storage and delivery, magnetic circuit design, cathode design, propulsion system architecture, avionics requirements, thermal management, embedded software design, and in-flight concepts of operation (CONOPs). Key job responsibilities The Lead Electric Propulsion Engineer supports the system and design throughout the hardware development lifecycle, from conception, prototyping, design validation & test, through production manufacturing, and flight operations. Key responsibilities will include - impact and influence the full scope of propulsion system design, development, and production including: propellant storage and delivery; thruster magnetic circuit design; cathode design; overall system architecture trades; Propulsion avionics requirements; thermal management; system integration; and propulsion embedded software - perform detailed system performance and risk analyses to support design trades, risk assessments, and risk mitigation plans - act with delegated design authority to approve: production non-conformances; changes in design, test, and systems engineering artifacts; and Concepts of Operations for the Amazon Leo Propulsion system - identify and assess technical risks based on data and outcomes in development, production, and flight operations - lead or support test execution for development, validation, and risk assessments - especially for integrated tests across multiple large vacuum chambers suitable for testing Hall effect thrusters - define test plans & test requirements to meet development and production test objectives - define procedures for in-flight responses to novel off-nominal scenarios, and directly support flight operations as needed - lead root-cause and corrective-action investigations supported by multidisciplinary engineering teams (e.g. design, manufacturing, test, quality) A day in the life The Lead Electric Propulsion Engineer will work within multi-disciplinary teams as the go-to source for electric propulsion knowledge. Teams will work on all aspects of propulsion system development, implementation and production and will require you, as propulsion expert, to ensure the key aspects of device operation are being properly considered and tested within constraints. You will aid in test planning, operation and data analysis, co-author test reports and disseminate impactful results. BASIC QUALIFICATIONS - Experience in developing functional specifications, design verification plans and functional test procedures - 5+ years of experience with electric propulsion technologies through design or test PREFERRED QUALIFICATIONS - Master's degree in electrical engineering, computer engineering, or equivalent - Experience working with interdisciplinary teams to execute product design from concept to production - Experience with the project management of technical projects - 7+ years of developing electric propulsion technologies through design & test cycles - Experience with Design of Experiments (DOE) - Familiarity with electric circuit design - Experience with finite element analysis for electromagnetic fields and/or fluid flow The base salary range for this position is listed below.
