Senior Electronics Engineer – Carrier Board

RIVR, an Amazon company, is building Physical AI by deploying autonomous robots for real-world doorstep delivery. Operating daily in diverse urban environments, RIVR's robots continuously learn from and navigate the millions of scenarios encountered during deliveries. By owning the full stack from software to hardware, RIVR is purpose-built for safety, reliability, and the customer from day one.

As a Electronics Engineer – Carrier Board, you will own the design of GPU/SoC carrier boards for our robotic compute platform — from schematic capture through PCB layout, bring-up, and production release. You will integrate high-speed digital interfaces and sensor front-ends into compact, reliable board designs for mobile Physical AI applications. Beyond technical depth, you will manage supplier and partner relationships, define development priorities, and drive sourcing decisions. You are the technical owner of the carrier board, not just a layout executor.

• Key job responsibilities
• Design and own carrier boards for GPU/SoC compute modules end-to-end: requirements → schematic → layout → bring-up → production release.

Integrate high-speed digital interfaces such as multi-gigabit Ethernet, DDR4, PCIe, MIPI CSI-2, GMSL SerDes, and USB 3.x.

Design electrical front-ends for sensors and modules including cameras, LIDARs, RADARs, and wireless connectivity (WiFi/5G).

Manage supplier and partner relationships: SoC vendors, connector suppliers, contract manufacturers, and module providers.

Evaluate and select components and suppliers based on cost, availability, quality, and roadmap fit.

Define and own development milestones and timelines; coordinate across internal teams and external partners.

Make trade-off decisions (features vs. schedule vs. cost) and communicate them clearly to stakeholders.

Perform board bring-up, debug, and validation of high-speed interfaces.

Provide signal integrity guidance for PCB layout (impedance control, length-matching, stackup definition).

Collaborate closely with firmware, mechanical, and systems engineering teams.

Basic qualifications

• - 5+ years designing carrier boards or motherboards for GPU/SoC compute modules.
• - Proven track record integrating high-speed digital interfaces (e.g., DDR4, PCIe, multi-gig Ethernet, GMSL) at board level.
• - Experience owning a board design end-to-end from requirements through production release.
• - Ideally worked in mobile, edge-compute, or automotive-adjacent applications (robotics, autonomous vehicles, drones, mobile AI platforms).
• - Hands-on schematic capture and PCB layout skills (Altium, OrCAD, or equivalent).
• - Strong understanding of signal integrity fundamentals.
• - Demonstrated ability to manage supplier and partner relationships and drive sourcing decisions.
• - Comfortable defining priorities, timelines, and trade-offs for a board development project.
• - Strong problem-solving skills and ability to debug high-speed interfaces during bring-up.
• - Master’s degree or higher in Electrical Engineering, Electronics, or a closely related field.

Preferred qualifications

• - Experience with NVIDIA Jetson, Orin, or Drive platform carrier board design.
• - Signal integrity simulation experience (eye-diagram analysis, S-parameter extraction).
• - Familiarity with automotive-grade design requirements (temperature range, vibration, component qualification).
• - Experience with power delivery design for high-current GPU modules.
• - Knowledge of thermal management integration at PCB level.
• - EMC/EMI pre-compliance testing experience.
