Electronics Engineer – Carrier Board, RIVR

Job description

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.
