Plumbing & Fluid Vehicle System Design Engineer

About The RolePebble is looking for a new graduate Mechanical Engineer, Hydraulic and Fluids System to join our Platform Team. Ownership is one of our core values, and from day one you'll own the design and development of real fluid system components on our platform — with senior engineers to mentor you, review your work, and help you grow. You'll collaborate with cross-functional teams to take your designs from concept through validation and into production.The ideal candidate is eager to take on ownership, has hands-on exposure to CAD tools (Catia and/or SolidWorks) through coursework, internships, or student projects, and is excited about hydraulic and fluid systems — fresh and waste water, pumps, valves, fittings, water heating, HVAC and cooling lines, coolants and refrigerants, and their integration with chassis, body, and electrical systems.ResponsibilitiesDesign and develop hydraulic and fluid system components, with guidance and review from senior engineersCollaborate with cross-functional teams across mechanical, electrical, thermal, manufacturing, and testMeet with suppliers and partner with our procurement team to help deliver initial parts, track quality, and resolve issues as they come upConduct feasibility studies and analyze data to optimize your designsCreate detailed engineering CAD models, drawings, plumbing schematics, and documentationPerform and support testing and validation of fluid systems, including leak, pressure, flow, and durability testingTroubleshoot and resolve hydraulic and fluid system issues as they ariseStay curious — track industry trends and advancements in fluid system engineeringProvide technical support to manufacturing and production teamsSupport the team in meeting regulatory, sanitation, and safety standards (e.g., NSF, plumbing codes, RVIA where applicable)Contribute to continuous improvement initiativesAreas You'll Learn and Contribute ToFresh water systems (tanks, pumps, distribution, filtration)Gray and black water (waste) systemsWater heating and deliveryPlumbing fixtures (sinks, showers, toilets)Pumps, valves, fittings, and hose/tubing routingHVAC and cooling lines, coolants, and refrigerantsThermal and fluid management interfaces with the battery and HVAC systemsIntegration between hydraulic/fluid systems and chassis, body, and electrical systemsFlow, pressure, and thermal analysis and simulationsLeak and durability validationRequirementsBachelor's or Master's degree in Mechanical Engineering or a related field (recent graduate or graduating within the next 6 months)0–2 years of experience; internships, co-ops, and research assistantships countHands-on experience with a parametric CAD tool (SolidWorks, Fusion 360, Creo, NX, or similar) through coursework, projects, or internships; exposure to Catia is a plusStrong fundamentals in mechanical engineering (fluid mechanics, thermodynamics, heat transfer, mechanics of materials, machine design)Strong analytical and problem-solving skillsExcellent communication and collaboration abilitiesAbility to learn quickly and thrive in a fast-paced environmentAttention to detail and accuracyAbility to manage multiple priorities and meet deadlinesOwnership mindset — you take responsibility for your work end-to-endNice to HaveInternship, co-op, or research experience in the automotive, RV, marine, aerospace, HVAC, or broader fluid systems industryHands-on experience through student engineering teams where fluid or thermal systems are relevant — FSAE, Baja SAE, Formula Electric (cooling loops), Solar Car (thermal management), Chem-E Car, rocketry/propulsion teams, or similarCoursework or projects in fluid mechanics, thermal systems, piping/hydraulic design, or HVACExperience with CFD or thermal/fluid simulation tools such as ANSYS Fluent, SolidWorks Flow Simulation, or SimScale; exposure to Star-CCM+ or OpenFOAM is a plusFamiliarity with GD&T or drafting standards (ASME Y14.5)Hands-on fabrication skills (machining, welding, tube bending, 3D printing)Exposure to piping or plumbing codes/standards (e.g., ASME, UPC, IPC, RVIA)Personal projects involving fluid systems, fabrication, or vehicles
