Built for the nation’s most critical missions.\nRocketdyne has powered American launch and national security missions for generations. Today we build the propulsion, power, and communications that get this country’s most important systems where they need to go - and keep them there. If it flies, we power it. If it protects the nation, we deliver it. Real hardware. Real stakes. Start your career with the team that the nation depends on.\nThe Role\nWe are seeking a Launch Propulsion Engineering Intern to join our team in Jupiter, FL for Summer 2027. This is an opportunity to contribute directly to real engineering work on flight programs alongside our experienced propulsion teams.\nAs an intern, you will work with our upper stage liquid propulsion, monopropellant, bipropellant, and electric propulsion engineering teams to develop and design hardware from initial concept through qualification testing and production support.\nProfessional Development Opportunities with Rocketdyne\nProject-based, direct professional experience in your field of study.\nWorking under guidance of experienced engineering and design professionals, with both manager and mentor relationships to build your skillset and prepare for your future career.\nRocketdyne-wide learning and development opportunities, includingInformation sessions for both technical and business topics spanning all Rocketdyne businesses and programs\n\nKey Responsibilities\nCreate and modify designs for various rocket propulsion systems.\nDesign, develop, and test products, including providing project time and cost estimates, supporting product manufacturing, and evaluating products for quality, safety, and cost.\nPlan the design, development, and testing of rocket chambers, nozzles, igniters, injectors, valves, actuators, and other associated rocket engine hardware.\nSupport analysis activities related to damage tolerance, durability, and design modeling, and coordinate with analysis and other engineering disciplines.\nDevelop and maintain component and assembly layouts, CAD models, and drawings for rocket engine hardware using CAD tools.\nPerform conceptual design, create design layouts, apply GD&T, conduct tolerance analyses, and support systems design and integration, including fabrication process identification and requirements flow-down from system to component level.\nConduct trade studies and support the development of schedules, test plans, component specifications, and procedures.\nHelp resolve hardware issues, nonconformances, and test anomalies in collaboration with engineering, quality, manufacturing, and test teams.\nAssist with development of technical documentation such as procedures, test reports, design reports, and presentations.\nParticipate in customer discussions, design reviews, and internal technical meetings to understand requirements and support engineering responses.\nPrepare and deliver an end-of-summer presentation summarizing your project work and key lessons learned.\nBasic Qualifications\nMajoring in Mechanical engineering, Aerospace engineering, or a related field. \nDemonstrated interest in spacecraft, propulsion, aerospace manufacturing, or other complex hardware development.\nAt the time of application, standing as a junior or senior undergraduate, or a current graduate student.\nRelevant coursework in one or more of the following:\nThermodynamics\nCombustion\nMechanics of materials\nDynamics/vibration\nFluid mechanics\nSpacecraft propulsion\nNozzle design\nLaboratory instrumentation and measurement\nStrong technical communication and organizational skills; prior experience in technical writing, seminars, or large group/conference presentations is especially beneficial.\nDemonstrated initiative to ask questions, challenge assumptions, and seek clarity where needed.\nAbility to work effectively on cross-functional teams with deadlines and decision gates, particularly on teams of 5 or more members.\nHousing and Relocation Assistance\nIf currently residing further than 50 miles from the Rocketdyne site, students are eligible to receive a stipend to cover the cost-of-living arrangements and relocation for the summer","description_format":"text","description_chars":4151,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Professional development","Relocation assistance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Aerospace Manufacturing","Power Supplies & Power Electronics"],"lifecycle":[{"event":"open","at":"2026-11-13T08:01:29Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":29,"reasons":["conf:6","win:early","comp:junior"],"computed_at":"2026-11-13T14:46:07Z"},"pay":null,"html_url":"https://alion.io/job/rocketdyne-designmechanical-engineering-intern-summer-2027","json_url":"https://alion.io/job/rocketdyne-designmechanical-engineering-intern-summer-2027.json","meta":{"generated_at":"2026-11-13T14:46:07Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":29663,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3866467},"rest":"https://alion.io/mcp/rest/get_company?id=3866467"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frocketdyne-designmechanical-engineering-intern-summer-2027"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Frocketdyne-designmechanical-engineering-intern-summer-2027"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Frocketdyne-designmechanical-engineering-intern-summer-2027"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/rocketdyne-designmechanical-engineering-intern-summer-2027\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frocketdyne-designmechanical-engineering-intern-summer-2027"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4226321}},{"tool":"search_jobs","arguments":{"company":"rocketdyne.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4226321},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
