Design Engineer Internship - Fall 2026

Design Engineer Interns will contribute to rotary engine component design, CAD modeling, and analysis in a fast-paced, prototype-heavy environment. Responsibilities include conceptual and detailed design of rotary engine components (housings, rotors, seals, bearings, combustors, cooling systems, etc.), creating and modifying 3D models and detailed drawings to ASME standards, performing basic design analysis (hand calculations, basic FEA), supporting rapid prototyping (additive manufacturing, CNC machining, in-house fabrication), participating in design reviews and tolerancing, iterating designs based on test results and manufacturing constraints, contributing to fixture/tooling design for engine assembly or testing, documenting designs and changes, and collaborating across mechanical, manufacturing, controls, and test teams. Candidates must be currently pursuing a Mechanical Engineering degree (Bachelor’s or Master’s) with strong CAD skills, hands-on prototyping ability, and a willingness to work in a fast-paced, small-team environment; U.S. person status preferred due to defense/aerospace projects. The internship offers hands-on ownership from concept through CAD modeling, analysis, prototyping, and testing iterations, with relocation as needed within CT and on-site duties in Bloomfield/Suffield.
