Mechanical Engineering Intern (Spring 2027)

Role Overview: As a Mechanical Engineering Intern, you will play a hands-on role in designing, developing, and testing complex mechanical systems for customer-facing projects. In this role, you will contribute to the full development lifecycle, from initial concept and simulation through prototyping, validation, and integration. Whether it’s designing mechanisms and enclosures, performing structural analysis, or designing precision assemblies for manufacturability, you’ll be making real contributions to complex systems. This internship is designed to accelerate your technical growth, giving you the chance to build a strong foundation in mechanical engineering while making an immediate impact. What You Will Do: Ownership: Contribute to the design of mechanical systems for customers across various industries Design & Analysis: Utilize CAD and simulation tools to develop structural, thermal, and tolerance analyses for electromechanical assemblies, using both hand calculations and FEA Thermal Management: Design and analyze active and passive thermal management systems for custom electronic systems and packaging solutions Prototyping & Testing: Participate in test campaigns to validate hardware performance under shock, vibration, thermal, and other environmental stresses What You Will Need: Current enrollment in college (Mechanical Engineering, Aerospace Engineering, Physics, Robotics, or related field) Experience in designing, modeling, simulation, and testing of electromechanical components or assemblies Experience with hand calculations, finite element analysis (FEA), and computer-aided design (CAD) Demonstrated passion and curiosity for mechanical engineering Strong problem-solving skills and initiative to overcome technical challenges Strong written and verbal technical communication skills; ability to explain design decisions and component selections What Would Be Useful: Experience in team-based design and build projects (e.g., Formula SAE, Solar Car, CubeSat, Rover Challenge, etc.) Familiarity with circuits and electrical engineering fundamentals Familiarity with manufacturing processes, such as machining, injection molding, water jetting, electro-discharge machining, and 3D printing Familiarity with generating thermal models for electronic assemblies; experience with thermal analysis of electronic devices with FEA and CFD modeling Experience with high-precision 3D printing processes and design for complex systems Ability to analyze and estimate structural loading from environmental sources Experience with fatigue and thermal testing of electromechanical assemblies Understanding of geometric dimensioning and tolerancing (GD&T) Compensation & Benefits: Salary: $70,400 annual salary, prorated for length of internship Flexible work hours and work from home policy 100% employer-paid health insurance (Medical, Dental, Vision) for employees + 50% dependent coverage Accrued paid time off policy, accrued sick days policy, and paid company holidays 401(k) retirement account and employer matching (Safe Harbor 4%) Housing stipend bonus Electric Vehicle (EV) charging ports Catered lunches, snacks, and accessible kitchen Preferred application deadline: August 31, 2026 Final application deadline: October 15, 2026 #J-18808-Ljbffr Second Order Effects, Inc.
