That’s our focus at JPL. We ask the biggest questions, then search the universe for answers-literally. We build upon ideas that have guided generations, then share our discoveries to inspire generations to come. Your mission-your opportunity-is to seek out the answers that bring us one step closer. If you’re driven to discover, create, and inspire something that lasts a lifetime and beyond, you’re ready for JPL.\nLocated in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence.\nThis opportunity is part of the Mechanical and Control Systems Division (3500), which engages in research, technology development, and the creation of advanced mechanical, robotics, guidance & control, thermal, propulsion, and electronic packaging systems. We develop hardware and systems from early architecture through design, fabrication, subsystem and system-level integration and test.\nAs a Level II Propulsion Systems Engineer, you will be working for the Thermal, Propulsion, and Materials Engineering Section (353), which provides leadership and unique world-class expertise in a wide range of technologies and technical discipline areas, including chemical and electric propulsion, thermal, materials, contamination control, analytical chemistry, and multiphase flow. This section is responsible for design, analysis, fabrication, testing, integration, and operations of thermal and propulsion flight systems for JPL missions. This section is also responsible for providing materials and process engineering, contamination control engineering, materials testing, and analytical chemistry support to technology and flight programs. You will be a member of the Chemical Propulsion Systems Group (353C) and will report to the Group Supervisor.\nWe are seeking an adaptable, high-energy professional who thrives in a dynamic, fast-paced setting and is comfortable navigating ambiguity. The ideal candidate possesses a risk-tolerant mindset, viewing challenges as opportunities to innovate, and excels in an evolving environment where decisiveness and agility are key to our collective success.\nResponsibilities\nProvide systems engineering, design, analysis and test support for the development, implementation, integration, and verification of chemical propulsion system architectures across all phases of the project lifecycle.\nContribute and execute hands-on propulsion system assembly, integration and test (I&T) activities.\nSupport propulsion flight hardware deliveries and interface with external component vendors, including environmental/hot-fire test support and verification of vendor processes and documentation.\nEngage in component and system-level problem resolutions and anomaly investigations.\nAssist in conducting and monitoring of spacecraft propulsion operations.\nPerform various spacecraft chemical propulsion subsystem static and transient analyses, such as flow-pressure drop, system sizing, blowdown, and waterhammer.\nUpdate, optimize and improve existing analysis tools and system models.\nGenerate documentation and user's manuals for in-house created analysis tools and models.\nDevelop and execute ground tests to validate and anchor analysis models, including analyzing and reducing the test data.\nCollaborate closely with the propulsion team to assist and provide analysis peer checks as well as providing systems design inputs.\nPrepare and communicate analysis methodology, assumptions, analytical and test result presentations to the team, the project and management.\nRequired/Minimum Skills\nBachelor’s degree in Aerospace/Mechanical Engineering or related technical discipline with a minimum of 3 years of related experience; Master’s degree with a minimum of 1 year related experience\nEducational background with strong fundamentals and/or demonstrated work experience in the application of advanced compressible & incompressible fluid mechanics, thermodynamics, heat and mass transfer, and rocket propulsion principles for propulsion systems.\nDemonstrated creating and understanding fluid schematics (P&IDs) and mechanical drawings.\nFamiliarity with developing, supporting and conducting propulsion subsystem ground testing.\nAbility to perform first-order (hand calculation) and excel-level calculations.\nPractical experience with commercial Computer-Aided Design (CAD) and Product Data Management (PDM) software, preferably Siemens NX and Teamcenter.\nProficiency with Microsoft Office applications.\nProficiency with programming languages, preferably MATLAB.\nCapable of reporting and presenting complex design, analytical and test results clearly to multi-disciplinary teams.\nAbility to work as a member of a team and independently work with limited supervision, when given only general instructions.\nDesired/Preferred Skills\nBasic understanding of spacecraft propulsion system-level interfaces (mechanical, thermal, electrical, etc.) that influence the propulsion subsystem design and operation.\nWorking knowledge with designing, releasing and fabricating ground support test hardware.\nFamiliarity with hardware qualification and acceptance test processes and campaigns.\nExperience supporting anomaly investigations, including root-cause analysis and development of corrective actions.\nExperience with performing and generating tools/code for spacecraft propulsion related subsystem analyses, such as flow-pressure drop and test data reduction.\nValidated analytical models through correlation with literature or test data, including identifying discrepancies and implementing model refinements.\nHands-on knowledge and experience with commercial Computational Fluid Dynamics (CFD) tools (Star-CCM+ and/or ANSYS) and commercial analytical tools (SINDA/FLUINT and/or GFSSP).\nUses discretion and independent judgment in evaluating problem solving approaches and solutions.\nExcellent verbal and written technical communication skills with the ability to work collaboratively in a team environment.\nJPL has a catalog of benefits and perks that span from the traditional to the unique.
