The internship scope will be tailored to your interests, with the possibility of exposure to multiple areas over the term.

Responsibilities

• Assist in designing on‑water boat tests and work with engineering test technicians to execute them.
• Analyze collected data and write summary reports.
• Request CFD & FEA simulations from the design analysis group for component‑level and vessel‑level validation before prototype hardware is available.
• Request component‑level structural tests during prototype testing and development of new products.
• Utilize load cells to measure propulsor loads during calm water, rough water, and turning operations.
• Feed simulation and test results into one‑dimensional performance prediction models.
• Drive hydrodynamic shape changes of gearcase and propeller components to meet functional requirements during development of new marine propulsors.

Required Qualifications

• Pursuing a Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or Naval Architecture.
• Minimum second‑semester sophomore status with at least 48 completed credits.
• Ability to work full‑time during the summer (May – August 2027).
• Interest or experience with aerodynamic/hydrodynamic system design, analysis, and optimization.
• Experience with Python, MATLAB, or similar tools for data analysis and tool creation.
• Experience designing and executing tests.
• Strong report writing and documentation skills.
• Experience with marine propulsion systems or boating is preferred.
• U.S. work authorization (no visa sponsorship available).

Working Conditions & Learning Opportunities

The internship is onsite at Plant 33 in Oshkosh, WI, with local travel only. The program provides hands‑on experience, mentorship from seasoned professionals, and the chance to apply academic knowledge to real‑world tasks.
