## About the Role

We are on the lookout for extraordinary engineers and scientists to join our team. Your previous experience in robotics isn't a prerequisite - it's your talent and determination that truly count.

We expect that many of our team members will bring diverse perspectives from various industries and fields. We are looking for individuals with a proven record of exceptional ability and a history of creating things that work., * Strong proficiency in C and modern C++ for embedded targets, including understanding of memory layout, linker scripts, startup code, and ISRs.

 * Hands-on experience building production firmware on **FreeRTOS** (tasks, queues, semaphores, mutexes, priority inversion, stack sizing) and on **bare-metal** systems (super-loops, interrupt-driven designs).
 * Solid working knowledge of **I2C**, **SPI**, **PWM** and **ADC**
 * Practical experience with **CAN-FD**: frame formats, bit timing, error handling, and integration with higher-layer protocols.
 * Experience with bootloaders, OTA/firmware updates, and secure boot.
 * Demonstrated ability to debug hardware/firmware interactions using **oscilloscopes** and **logic analyzers** (e.g., Saleae, Keysight, Tektronix)
 * capturing signals, decoding protocols, and reasoning from waveforms to root cause.
 * Comfortable reading datasheets, reference manuals, and schematics.
 * Proficient with Git, toolchains (GCC/Clang, arm-none-eabi), build systems (CMake/Make), and on-target debuggers (GDB, J-Link, ST-Link, OpenOCD).
 * *Motor control** experience: BLDC/PMSM and FOC
 * **Zephyr RTOS**: device tree, Kconfig, driver model, and writing out-of-tree modules.
 * EtherCat and FoE

## Description

* You deeply believe that this is the most important mission for humanity and needs to happen yesterday.
 * You are highly technical - regardless of the role you are in. We are building technology; you need to understand technology well.
 * You care about aesthetics and design inside out. If it's not the best product ever, it bothers you, and you need to "fix" it.
 * You don't need someone to motivate you; you get things done.

Why We Are Hiring for This Role:

 * To develop, Develop, optimize, and maintain firmware in C and C++ for 32-bit microcontrollers.
 * Build applications on top of FreeRTOS and write bare-metal drivers.
 * Design and implement peripheral drivers and integrations: I2C, SPI, UART, PWM, ADC, and CAN-FD.
 * Bring up new hardware: validate power rails, clocks, peripherals, and communication buses.
 * Profile and tune firmware for timing, memory footprint, and power consumption.
 * Debug complex hardware/firmware issues at the bench using oscilloscopes, logic analyzersand multimeters.
 * Write clear, testable code with unit tests, on-target tests, and code reviews.
 * Collaborate with hardware engineers on schematic and layout reviews from a firmware perspective.
 * Document designs, bring-up procedures, and known issues.
