## Description

## Job Overview

We are seeking an experienced Embedded Linux Engineer to lead the development of our software platform from scratch. As a key member of our team, you will be responsible for taking a custom-built board and getting Linux to boot and run reliably on it. You will also ensure the stack remains maintainable as we ship and update units in the field.

## Key Responsibilities

- Board bring-up: Take freshly fabricated carrier boards from assembly to reliable booting, proving out power, memory, and communication interfaces hands-on with hardware.

- Bootloader & kernel configuration: Stand up the bootloader and configure the Linux kernel to recognize and drive our specific hardware.

- Device drivers & device tree: Describe our custom hardware to Linux and integrate necessary drivers for peripherals.

- Build & deploy with Nix / NixOS: Own our operating system defined as code, producing reproducible images and building safe update and rollback paths.

- Networking & system services: Configure on-device networking and system services for higher-level software.

- Reliability & maintainability: Build a robust and serviceable platform across the product's life.

- Cross-functional integration: Partner with firmware and hardware teams, sitting at the hardware-software boundary.

## What We're Looking For

- Top-notch engineering intuition and first-principles thinking for designing complex products.

- Ability to independently identify critical information gaps and apply effort to close them.

- Comfort with imperfect information and making sound decisions.

- Persistence in finding root causes through data-driven methods.

- Collaboration and teamwork, breaking down information silos.

## Qualifications

### Required

- BS in Computer Science, Electrical/Computer Engineering, or equivalent experience.

- 3+ years of experience building and shipping embedded Linux on custom hardware.

- Proven board bring-up experience.

- Hands-on experience with the boot chain: bootloader, kernel configuration, drivers, and device tree.

- Fluency in C/C++ and the embedded Linux toolchain.

- Exposure to embedded communication interfaces.

### Preferred

- Experience with Nix/NixOS.

- Experience with OS configuration as code, Yocto, Ansible.

- Production Rust experience.

- Familiarity with ARM SoCs/SoMs on custom carrier boards.

- Background in automotive, aerospace, defense, robotics, or energy.

## Role Requirements

- Onsite role based in San Bruno, CA.

- Willingness to support 10% travel domestically and internationally.

- Ability to work extended and weekend hours when necessary.

- Physical demands: working on feet for extended periods, lifting and carrying 50lbs.

## Compensation

A reasonable estimate of the current salary range is $130,000-$180,000 annually. Compensation packages also include early-stage equity and access to company-sponsored benefit plans.
