Mechanical Engineering Internships
Updated hourly from a 20M+ job database, this list surfaces mechanical engineering internships across product development, R&D, energy, manufacturing, industrial engineering, quality, and testing.
Mechanical engineering interns can contribute to CAD and drawing updates, prototyping, test planning, data analysis, fixture design, thermal or structural analysis, manufacturing support, quality investigations, and documentation. Product companies, industrial manufacturers, engineering consultancies, energy businesses, research organizations, construction teams, and hardware startups provide different balances of design and hands-on work. Some employers run a summer cohort with orientation, mentors, and presentations; others hire a co-op for multiple terms or add an intern to one project team. Eligibility may depend on engineering major, academic year, completed mechanics or design coursework, and familiarity with CAD, simulation, GD&T, machining, or test equipment. Design teams, labs, fabrication projects, and prior technical work can demonstrate readiness.
Use the source posting to identify the product, system, and development stage rather than judging by title alone. Verify whether the intern will design new components, sustain existing products, support production, run tests, or analyze reliability. Check program dates, enrollment and graduation criteria, required tools, portfolio or project examples, work authorization, and whether the position is summer, semester, or co-op. Facility attendance, safety training, protective equipment, lifting, travel, and shift schedules can be central to manufacturing and test roles. Compare supervision, access to engineers and technicians, the expected deliverable, and whether interns own a bounded project or mainly support recurring tasks. Recruiting can begin early for large cohorts, while plant and project needs may generate later openings, so confirm every deadline directly.
Mechanical engineering internships can be browsed and filtered at no cost. A free Simplify account adds saved jobs, application tracking, and Copilot form assistance. Match the appropriate portfolio version to each role, and verify technical tests, schedules, and relocation details at the employer source.

Electrical Engineering Internships
This list tracks 100K+ company job sources and updates hourly with electrical engineering internships across circuits, electronics, embedded systems, RF, controls, power, CAD, and hardware development. Electrical engineering interns may design or review circuits, lay out boards, write embedded code, test electronics, analyze signals, model power systems, support controls, characterize RF performance, or document hardware. Semiconductor companies, product manufacturers, utilities, aerospace and defense teams, engineering consultancies, research laboratories, and hardware startups provide different technical environments. A summer program may include a cohort, mentor, and final presentation, while a co-op or direct team internship can extend across multiple academic terms and carry deeper ownership. Employers often screen for electrical or computer engineering study, completed circuits or signals coursework, and experience with lab instruments, CAD or EDA tools, programming, or simulation. Labs, design teams, and personal hardware projects can demonstrate applied ability. Match the posting to the subdiscipline you want to practice. Verify whether the work centers on analog, digital, power, RF, controls, embedded systems, verification, or test, and identify the product or infrastructure involved. The source listing should clarify program dates, enrollment and graduation windows, tool and coursework requirements, onsite laboratory or facility attendance, safety training, shift schedule, travel, and work authorization. Some regulated or defense-related positions include export-control, citizenship, or clearance conditions that must be read exactly. Compare how interns receive design review, access equipment, and own a deliverable; a role limited to repetitive testing offers a different learning experience from one that carries a circuit through design and validation. Check compensation and relocation information separately. Electrical engineering internships can be reviewed and filtered for free. A free Simplify account enables saved jobs, application tracking, and Copilot form completion. Recheck tool, project, worksite, and eligibility requirements at the original posting before applying. Laboratory access and technical interview expectations may change as teams refine the project.

Aerospace Internships for College Students
This list tracks 100K+ company job sources and updates hourly with aerospace internships across software, autonomy, electronics, embedded systems, design, research, and technical support. Aerospace interns may write flight or ground software, design mechanical or electrical components, support autonomy and controls, build embedded systems, run laboratory or vehicle tests, analyze data, prepare systems documentation, or assist manufacturing and integration teams. Aircraft and spacecraft manufacturers, defense contractors, suppliers, research organizations, aviation operators, and aerospace startups differ in scale and program structure. Larger employers may recruit a summer cohort with orientation, mentorship, and intern presentations; smaller or project-driven teams may hire against a specific vehicle or contract. Engineering major, academic year, technical coursework, and tools such as CAD, simulation, programming, or test equipment often shape eligibility. Design competitions, labs, research, and personal technical projects can provide useful evidence. Review the system and assignment behind the title. Verify whether the work is conceptual design, production support, test, verification, operations, or maintenance, and whether the intern owns a bounded project. The employer posting should confirm enrollment and graduation dates, program term, technical prerequisites, GPA or transcript requests, onsite schedule, travel, shift work, and any relocation or housing information. Aerospace roles can also contain export-control, citizenship, or security-clearance conditions; read the exact requirement rather than inferring it from the company. Recruiting for established summer programs can begin early, while smaller teams may post later. Compare training, manager access, hands-on opportunity, and expected deliverables, and check whether compensation is hourly or stipend-based before adding separate relocation benefits. Ask how interns interact with test, manufacturing, software, and systems teams and whether confidential project work can later be described in a portfolio. Aerospace internships can be browsed and filtered without an account. A free Simplify account supplies saved jobs, application tracking, and Copilot form entry. Verify transcript, export-control, clearance, worksite, and project requirements on each employer's source page.

Mechanical engineering internships usually involve designing, analyzing, building, testing, or improving physical systems. Roles may cover CAD, product design, thermal analysis, structures, materials, prototyping, test fixtures, mechanisms, robotics hardware, vehicles, consumer products, medical devices, manufacturing support, or reliability work. Read the project description closely because some employers use broad engineering-intern titles for mechanical work.
Mechanical engineering is the broader discipline, while mechanical hardware roles are usually tied to physical product teams that design enclosures, mechanisms, assemblies, fixtures, thermal systems, or manufacturable hardware. A mechanical hardware internship may sit inside a hardware, robotics, aerospace, consumer electronics, automotive, or medical-device team. The best fit depends on whether you want general mechanical design exposure or product-focused hardware ownership.
Strong foundations include statics, dynamics, mechanics of materials, thermodynamics, heat transfer, manufacturing processes, tolerancing, and design for manufacturability. Useful tools often include SolidWorks, Fusion 360, Creo, CATIA, ANSYS, MATLAB, Python, Excel, GD&T, and basic lab or shop experience. You do not need every tool, but your resume should show that you can turn engineering concepts into tested designs.
The strongest projects show a real design loop: requirements, modeling, tradeoffs, build or simulation, measurement, failure analysis, and iteration. Examples include robotics mechanisms, vehicle subsystems, thermal tests, 3D-printed assemblies, fixtures, product teardowns, manufacturing improvements, finite-element analysis, or capstone hardware. Include what you personally owned, what constraints mattered, and how you validated the result.
Look for ownership of design, analysis, testing plans, root-cause investigation, documentation, and engineering review. Technician-heavy roles often emphasize operation, maintenance, repair, setup, assembly, or repetitive testing without much design authority. Some hands-on work is valuable for mechanical engineers, but a strong internship should still include mentorship, engineering judgment, and a clear project you can explain afterward.
Expect questions about your projects, design decisions, mechanical fundamentals, tradeoffs, and how you handled failed tests or uncertain requirements. Interviewers may ask about CAD choices, tolerances, materials, loads, thermal behavior, manufacturing constraints, or how you would debug a physical system. Be ready to walk through one project from problem definition through validation, not just show the final result.
Yes, if the role involves mechanical design or mechanical hardware work. Many mechanical interns work in industries where the title does not say mechanical engineering directly, such as robotics, autonomous vehicles, consumer hardware, energy, medtech, aerospace, industrial equipment, or advanced manufacturing. Compare the actual responsibilities, tools, and manager support rather than filtering only by company category.
Compare the project scope, design ownership, mentorship, access to prototypes or test equipment, review process, location, pay, and return-offer path. A strong internship should give you concrete engineering artifacts: drawings, analyses, test plans, design reviews, validated prototypes, or process improvements. Use Simplify to save roles across industries and track which applications match the mechanical skills you want to develop.
