Pebble 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.
Responsibilities
- Design and develop hydraulic and fluid system components, with guidance and review from senior engineers
- Collaborate with cross-functional teams across mechanical, electrical, thermal, manufacturing, and test
- Meet with suppliers and partner with our procurement team to help deliver initial parts, track quality, and resolve issues as they come up
- Conduct feasibility studies and analyze data to optimize your designs
- Create detailed engineering CAD models, drawings, plumbing schematics, and documentation
- Perform and support testing and validation of fluid systems, including leak, pressure, flow, and durability testing
- Troubleshoot and resolve hydraulic and fluid system issues as they arise
- Stay curious — track industry trends and advancements in fluid system engineering
- Provide technical support to manufacturing and production teams
- Support the team in meeting regulatory, sanitation, and safety standards (e.g., NSF, plumbing codes, RVIA where applicable)
- Contribute to continuous improvement initiatives
Areas You'll Learn and Contribute To
- Fresh water systems (tanks, pumps, distribution, filtration)
- Gray and black water (waste) systems
- Water heating and delivery
- Plumbing fixtures (sinks, showers, toilets)
- Pumps, valves, fittings, and hose/tubing routing
- HVAC and cooling lines, coolants, and refrigerants
- Thermal and fluid management interfaces with the battery and HVAC systems
- Integration between hydraulic/fluid systems and chassis, body, and electrical systems
- Flow, pressure, and thermal analysis and simulations
- Leak and durability validation
Requirements
- Bachelor'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 count
- Hands-on experience with a parametric CAD tool (SolidWorks, Fusion 360, Creo, NX, or similar) through coursework, projects, or internships; exposure to Catia is a plus
- Strong fundamentals in mechanical engineering (fluid mechanics, thermodynamics, heat transfer, mechanics of materials, machine design)
- Strong analytical and problem-solving skills
- Excellent communication and collaboration abilities
- Ability to learn quickly and thrive in a fast-paced environment
- Attention to detail and accuracy
- Ability to manage multiple priorities and meet deadlines
- Ownership mindset — you take responsibility for your work end-to-end
Nice to Have
- Internship, co-op, or research experience in the automotive, RV, marine, aerospace, HVAC, or broader fluid systems industry
- Hands-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 similar
- Coursework or projects in fluid mechanics, thermal systems, piping/hydraulic design, or HVAC
- Experience with CFD or thermal/fluid simulation tools such as ANSYS Fluent, SolidWorks Flow Simulation, or SimScale; exposure to Star-CCM+ or OpenFOAM is a plus
- Familiarity 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

Which automotive companies sponsor F-1 STEM OPT visas in California?
Tesla's Fremont factory and engineering offices, Rivian's software and vehicle development teams, Lucid Motors in Newark, and major Tier 1 suppliers such as Aptiv and BorgWarner have California operations with documented STEM OPT sponsorship activity. Autonomous vehicle companies like Waymo and Cruise also regularly hire STEM OPT candidates in software, sensor systems, and machine learning roles. Sponsorship practices vary by team and role, so verifying directly with each employer is important.
Which cities in California have the most automotive F-1 STEM OPT sponsorship jobs?
The San Francisco Bay Area, particularly Fremont, Palo Alto, and Santa Clara, concentrates electric vehicle and autonomous driving employers. Southern California, including Irvine, Torrance, and the greater Los Angeles area, hosts traditional automotive OEMs, design studios, and Tier 1 suppliers. Silicon Valley's overlap with automotive tech also makes San Jose a meaningful cluster for software-defined vehicle and connected car roles.
What types of automotive roles typically qualify for F-1 STEM OPT sponsorship?
Roles qualifying for STEM OPT extension generally fall under STEM-designated degree fields recognized by the Department of Homeland Security. In automotive, this typically includes electrical engineering, mechanical engineering, computer science, data science, and software engineering positions. Roles in autonomous systems, battery technology, vehicle-to-infrastructure software, embedded controls, and manufacturing process engineering commonly meet the technical degree alignment STEM OPT requires. Non-engineering roles such as sales or program management less commonly qualify.
How do I find automotive F-1 STEM OPT sponsorship jobs in California?
Migrate Mate is built specifically for international students and filters automotive job listings in California by confirmed STEM OPT sponsorship history, saving you from guessing which employers will support your visa status. You can search by city, role type, and employer filing history to surface companies that have sponsored STEM OPT candidates in automotive disciplines before. Cross-referencing DOL Labor Condition Application records through OFLC Wage Search can also help verify an employer's prior sponsorship activity.
Are there any California-specific considerations for F-1 STEM OPT sponsorship in automotive?
California's strict worker classification laws and its status as an E-Verify optional state for most private employers can affect how automotive companies structure STEM OPT arrangements. California also has additional state tax obligations that apply to STEM OPT workers. The state's zero-emission vehicle regulations drive heavy employer investment in EV and battery engineering, making California automotive roles particularly concentrated in the STEM disciplines that align well with STEM OPT eligibility requirements.
