About 1X

We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it’s not.

To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you’re inspired by this, you’ll thrive here. We’ve been at this since 2014 and we’re at the point where the hard problems are behind us and the hard work is in front of us.

NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We’re not demoing it - we’re shipping it. We’re excited to meet you, if this excites you.

If you’ve spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We’re scaling, we’re hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.

About the Team

The Foundations team owns the platform that NEO runs on from the moment silicon powers up to the software stack that perception, planning, and controls depend on. We build and ship the embedded Linux distribution, BSP, kernel, drivers, and system software end-to-end: this is the layer between hardware and intelligence, and its stability, boot speed, and update reliability directly determines what every other team can ship. If you want to own the OS as a product, not an afterthought, this is that team.

Your Charter

Own the embedded Linux foundation for NEO from BSP and kernel through distribution, provisioning, and OTA updates, ensuring it boots fast, stays stable, debugs cleanly, and updates confidently as we scale from prototypes to a growing fleet in homes and warehouses. This is critical-path work: every other team’s ability to develop, test, and ship depends on a platform that is reproducible, observable, and production-grade. The operating system is a product, and you are its owner.

Key Outcomes

Ship a production-grade custom embedded Linux distribution (Yocto) with reproducible builds, fast deterministic startup, and release artifacts that the full engineering team can depend on across hardware revisions
Own kernel and driver development end-to-end device tree, board bring-up, peripheral enablement such that new hardware platforms are enabled on schedule with minimal downstream disruption
Deliver reliable fleet tooling for provisioning, flashing, and OTA updates that scales from dozens of prototypes to high-volume production without manual intervention or data loss
Build CI/CD for embedded images and kernel builds that catches regressions before they reach hardware, reducing bring-up cycles and unblocking dependent teams faster

Key Competencies

Platform ownership mindset treating the OS as a product with real users, not a build artifact; holds strong opinions about release engineering, reproducibility, and what “production-grade” means for embedded Linux
Kernel-level fluency debugging confidently at the kernel level, traces software root causes from hardware symptoms, and writes production device drivers for common buses (I2C, SPI, CAN, USB, Ethernet, PCIe)
Schematic literacy reading hardware schematics to reason about behavior from software symptoms, reducing the round-trip between firmware investigation and hardware root cause
High-ownership operator defining the standard rather than inheriting it; takes end-to-end responsibility from prototype bring-up through fleet-scale production hardening

Minimum Requirements

5+ years shipping embedded Linux systems in production, including BSP, kernel customization, and distribution ownership
Proven experience writing production device drivers and working with Yocto or Buildroot for custom embedded distributions
Demonstrated ability to debug at the kernel level and trace software root causes, comfortable with kernel tracing tools, serial consoles, and crash capture

Preferred Skills

Experience designing and operating OTA update systems for embedded fleets, including rollback, partial updates, and reliability under real-world network conditions
Familiarity with real-time Linux extensions (PREEMPT_RT) or low-latency kernel configuration for robotics or industrial applications
Experience taking a hardware platform from early prototype through high-volume production, including reliability and optimization tradeoffs as hardware evolves
Background in robotics, autonomous vehicles, or other physical systems where platform stability has direct operational consequences

What does a successful 1X Team Member look like

Team members at 1X who thrive here are builders. They move fast, own their work completely, and treat time like it’s the one thing you can’t get back - because it is. They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask. We push each other to be better, and we do it with honesty and respect. =
