Jet Pump Design Engineer

About The Business: Electrified Professional Watercraft Ltd (ePWC Ltd) designs and manufactures electric drivetrain conversion systems for professional personal watercraft (PWC). Our retrofit solutions enable existing petrol-powered craft to be converted to zero-emission electric propulsion, extending asset life while reducing operating costs, emissions and maintenance. We serve the maritime clean technology sector, targeting emergency services, search and rescue, police, harbour authorities, defence and other commercial operators in the UK and internationally. Our products support the transition to sustainable maritime operations without requiring organisations to replace their existing fleets.

Overview: Electrified Professional Watercraft Ltd (ePWC Ltd) is seeking a motivated engineering intern to support the development of next-generation electric propulsion systems for professional personal watercraft (PWC). The internship will focus on using Computational Fluid Dynamics (CFD) to analyse the performance of an existing jet pump and identify design improvements that optimise efficiency when driven by an electric motor rather than a conventional internal combustion engine.

Desirable Skills: We are looking for a student with an interest in fluid mechanics, marine engineering, mechanical engineering or aerospace engineering. Experience with CFD software such as ANSYS Fluent, STAR-CCM+, OpenFOAM or similar is desirable, together with an understanding of fluid dynamics, rotating machinery and data analysis. Strong analytical, problem-solving and communication skills are essential.

Job Description:

Main Responsibilities:

• Develop CFD models of an existing personal watercraft jet pump and intake system.
• Analyse flow characteristics, pressure distribution, cavitation potential and hydraulic losses across a range of operating conditions.
• Investigate how the different torque and speed characteristics of electric motors influence jet pump performance.
• Identify opportunities to improve efficiency through modifications to the impeller, stator, nozzle, intake duct or other hydraulic components.
• Compare simulation results with available performance and test data.
• Produce technical reports and present recommendations supported by engineering evidence.
• Work closely with the engineering team to evaluate the practicality of proposed design changes for prototype manufacture and testing.
