## About the Role

* An early-career embedded engineer who likes writing code that makes hardware move, and learns fast.
 * Comfortable in a lab: you can read a schematic, use a multimeter and scope, and solder a wire.
 * Someone who understands the basics of electronics and microcontrollers, not just software.
 * Already using AI coding tools (Claude Code, Copilot, ChatGPT, or similar) in your work, with the judgment to tell when the AI is wrong.
 * A collaborative, curious engineer who asks for help early and works hard to get things right.
 * Excited about robotics, real hardware, and shipping systems that work outside the lab, including in demanding DoD and industrial environments., * B.S. in Computer Engineering, Electrical Engineering, Computer Science, Mechatronics, or a closely related field (completed, or completing within the next year).
 * 0 to 3 years of professional experience. Internships, co-ops, senior design, and serious personal or team projects count.
 * C or C++ on a microcontroller (STM32, Arduino, Teensy, ESP32, or similar).
 * Python and Git.
 * Basic understanding of serial communication (UART, SPI, I2C, CAN, or USB).
 * Basic soldering and lab equipment skills.
 * Good documentation habits and clear written and verbal communication.
 * U.S. Citizenship (due to DoD requirements).

Preferred:

 * STM32 HAL, an RTOS, or bare-metal firmware experience.
 * Motor control experience (BLDC, encoders, current sensing).
 * ROS or ROS 2, Linux, or NVIDIA Jetson experience.
 * Test automation or CI experience.
 * Robotics club, competition team, or projects you can show us.
 * Prior experience in a startup or small hardware team.

## Description

* Write, test, and debug C/C++ firmware for STM32 microcontrollers: motor control, sensors, power monitoring, and communication between links.
 * Bring up firmware on new boards with the electrical team, including our 48 V system, with a senior engineer reviewing every safety limit.
 * Use AI coding tools to draft code, then review, test, and fix it yourself.

Test and Release:

 * Help build automated tests and a repeatable build-and-flash process so every robot runs the same firmware.
 * Run long motor and system tests, log the data, and track down bugs.
 * Document how things work so the next person can pick it up.

Robot Software and Operator Interface:

 * Help move our robot software to ROS 2 on an NVIDIA Jetson and keep it running.
 * Help build the operator screen and camera feed that inspectors use, and the way inspection data is saved., * Our Head of Robotics, day to day, on firmware and robot software. You will be his backup on both.
 * The CEO on product priorities and customer programs.
 * Senior engineering mentors who review your work and guide you each week.
 * The electrical and mechanical engineering team on bring-up, integration, and test.

Company Core Values:

 * Do what you say, say what you do.
 * We all make mistakes; it is what we do afterwards that defines us.
 * Treat all with respect. Period.
 * Leave a situation better than you found it.
 * Just because something has always been done a certain way, doesn't mean it has to be done that way in the future.
