Hardcore Electrical Engineer – Humanoid Robotics

At 1X, we are building humanoid robots that will take on the hardest real-world problems. This is not incremental engineering—it is high-stakes, first-principles design. Our team is small, flat, and relentlessly driven. We move fast, break down barriers, and expect every engineer to own entire systems end-to-end. Strong communication and a hands-on mindset are essential.

What You’ll Do 

As a Hardcore Electrical Engineer, you will push the boundaries of what’s possible in robotics. You’ll design and integrate electrical systems that operate at the edge of performance, reliability, and manufacturability. Expect to:

• Architect power electronics and distribution for a high-actuation, high-density humanoid robot

• Design advanced PCB layouts for sensing, actuation, and compute modules under extreme constraints

• Build real-time embedded systems using microcontrollers and high-speed digital interfaces

• Debug, characterize, and optimize across thermal, EMI, and signal-integrity domains

• Develop rapid prototypes, validation rigs, and custom tools to accelerate iteration

• Work shoulder-to-shoulder with mechanical, software, and AI teams to bring robots to life

Your Toolkit

• PCB CAD (Altium)

• Embedded C/C++, Verilog/VHDL

• STM32/ARM microcontrollers, Xilinx/Intel FPGAs

• High-speed buses: CAN, SPI, I²C, LVDS, Ethernet

• Oscilloscopes, logic analyzers, power analyzers, thermal sensors

• A maker’s mindset: soldering iron in one hand, scope probe in the other

Who You Are

• You thrive in the chaos of hard problems and unfinished playbooks

• 5+ years of experience designing, building, and shipping real hardware (robotics, aerospace, automotive, or similar)

• Proven track record in power systems, embedded design, or high-density PCB layout

• Obsessive about reliability, yet willing to prototype fast and learn by doing

• A clear communicator who can align cross-functional teams under pressure

• Excited by the idea of making humanoid robots work in the real world
