Pebble is a sustainable living startup defining a new way to live, work, and explore from anywhere with a 100% electric, hassle-free RV trailer. Built by a team of experts in both automotive and consumer technology, Pebble combines electrification with cutting‑edge automotive technology for a travel trailer experience that removes the hassles RV trailer owners have struggled with for decades.

At Pebble, we are building out the future of lighter, more flexible living. We see a world where your home can be anywhere you want to take it. Pebble blends the best of what it means to be at home, on the road, and off‑grid into something useful and magical. This is a collective effort our team is dedicated to making not just products, but a lifestyle that is truly sustainable.

If the idea of building out the future sparks your imagination and intersects with your skills, we'd love to meet you.

Pebble is seeking a Senior Electrical Harness Engineer to own the design, development, and release of vehicle wire harness systems across the Pebble Flow platform. This is a fundamentally electrical role, you bring deep EE expertise in circuit design, connector systems, and signal integrity with the additional ability to engage meaningfully with mechanical routing constraints, package space, and 3D harness geometry in CATIA.

You will be the connective tissue between our electrical architecture and the physical vehicle translating schematics into manufacturable, reliable harness designs that survive demanding off‑grid and road environments. You will work closely with electrical architects, systems engineers, mechanical designers, and manufacturing to take harnesses from concept through production release.

• Own end-to-end harness design: from schematic capture and wire/connector selection through harness drawing packages, formboard layouts, and production release
• Use Zuken E3.series as the primary tool for schematic capture, harness engineering, and connector/wire database management
• Develop and maintain harness drawings, splice diagrams, connector face views, and wire lists to automotive documentation standards
• Define wire gauges, insulation ratings, terminal crimp specifications, and connector sealing strategies appropriate for HV and LV environments
• Work in CATIA to review and contribute to 3D harness routing evaluating bend radii, clipping strategy, clearance to heat sources, and packaging within the vehicle structure
• Collaborate with mechanical engineers on harness path definition, bracket and clip placement, and grounding point locations
• Apply automotive harness design standards (USCAR, IPC/WHMA-A-620, or OEM equivalents) to ensure quality and reliability
• Support DFMEA and design reviews for harness systems; identify failure modes related to chafing, connector fretting, thermal exposure, and moisture ingress
• Manage connector and terminal component selection, driving standardization across the vehicle to reduce part count and supplier complexity
• Partner with manufacturing and harness suppliers on DFM feedback, assembly instructions, and process validation
• Support bring-up, integration testing, and field issue diagnosis, including continuity testing, insulation resistance, and fault tracing in prototype vehicles
• Maintain harness BOM accuracy and coordinate ECO releases with the broader electrical team

• Bachelor's degree or higher in Electrical Engineering or closely related field
• 6+ years of experience in automotive or vehicle electrical engineering, with hands‑on ownership of harness design and release
• Proficiency in Zuken E3.series for schematic capture, harness engineering, and wire/connector data management
• Working knowledge of CATIA (V5 or 3DX) sufficient to navigate 3D harness geometry, assess routing feasibility, and collaborate with mechanical design teams
• Deep understanding of wire and cable selection: ampacity, voltage drop, insulation temperature ratings, shielding, and bundling practices
• Strong connector and…
