This exciting opportunity is based in the Greater Portland, Maine area and offers competitive compensation of $100,000-$150,000 annually, plus stock options and comprehensive benefits.\n\nThe successful candidate will lead the design, development, and testing of hybrid rocket engines and associated propulsion subsystems. This hands-on role combines advanced engineering analysis with practical build and test execution, making it ideal for engineers who enjoy both theoretical design work and getting their hands dirty in the field.\n\nKey responsibilities include designing hybrid propulsion system components and fluid systems, performing thermal, stress, and vibration analyses, and conducting simulation and modeling using MATLAB, Simulink, and similar tools. You'll be responsible for materials selection for high-stress, high-temperature environments and will support the build and assembly of engines and test hardware.\n\nThe role involves conducting static and dynamic propulsion testing, writing comprehensive test plans, analyzing test data, and documenting results. You'll troubleshoot and resolve complex propulsion issues across mechanical, electrical, and software interfaces while working closely with cross-functional engineering teams.\n\nThe ideal candidate will have experience in hybrid propulsion systems, with liquid propulsion experience considered as an alternative qualification. This position requires someone comfortable with hands-on engineering work, from concept development through hot fire testing, who can take ownership of projects and contribute to shaping future vehicle propulsion architectures.\n\nThis is an onsite role perfect for candidates who value outdoor living and thrive in a close-knit, collaborative environment where every contribution makes a meaningful impact on cutting-edge aerospace technology.","en","https:\u002F\u002Fwww.darwinrecruitment.com\u002Fjob\u002F5819821092764-lead-propulsion-engineer-portland-maine\u002F",{"items":38},[39,55,74,85,106,120,133,148,166,179,193,206,220,233,247],{"id":40,"slug":41,"title":42,"skills":43,"budget":52,"duration":22,"location":22,"onsitePercent":22,"contractType":25,"foundAt":53,"category":54},10330,"servicemonteur-hvac","Servicemonteur HVAC",[44,45,46,47,48,49,50,51],"HVAC","MBO-niveau","Rijbewijs B","VCA","NEN 3140","Elektro","Koeltechniek","WTB","3.700-4.400 EUR\u002FMonat","2026-06-03T06:04:15+00:00",{"id":28,"slug":29,"label":30},{"id":56,"slug":57,"title":58,"skills":59,"budget":70,"duration":22,"location":71,"onsitePercent":24,"contractType":25,"foundAt":72,"category":73},10293,"service-techniker-fuer-hochwertige-maschinen-niederlande","Service Techniker für hochwertige Maschinen (Niederlande)",[60,61,62,63,64,65,66,67,68,69],"Elektrotechniek","Mechatronica","Hydrauliek","Service","Buitendienst","Storingen oplossen","Hogedrukpompen","Motoren","PTO","Pompen","4.400 EUR\u002FMonat","Randstad","2026-06-03T06:03:40+00:00",{"id":28,"slug":29,"label":30},{"id":75,"slug":76,"title":77,"skills":78,"budget":22,"duration":22,"location":82,"onsitePercent":24,"contractType":25,"foundAt":83,"category":84},10261,"mechanicalmechatronic-engineer-food-manufacturing","Mechanical\u002FMechatronic Engineer -
