Our Mission at Scythe

Humanity has lost touch with nature - we’ve traded dirt and trees for asphalt, and we rely on loud, polluting, gas-powered machines to care for our limited natural spaces.
Scythe is forging a new future by building intelligent, all-electric machines that unlock a new superpower: the ability to care for the outdoors pollution-free at enormous scale. From today’s first steps in landscape maintenance to full-fledged re-terraforming in the future, Scythe is pioneering autonomous machinery that supports the ingenuity of humans, multiplying our power to nurture our planet.
At Scythe, you’ll work with a team of world-class experts in everything from computer vision to mechanical engineering, pushing the limits of possibility and growing by overcoming hurdles along the way.
The world needs what we’re building—come join us in making it a reality.

Firmware Engineer at Scythe Robotics

Scythe is seeking an experienced Firmware Engineer to help bring the future of outdoor power equipment to life. Our autonomous mower, M.52, depends on multiple embedded systems responsible for tasks like power management, sensor management, user interfaces, and more. As a Firmware Engineer at Scythe, you will be instrumental in developing the firmware that powers these microcontroller-based embedded systems and allows them to communicate with each other and the main robot "brain" system. You’ll be responsible for creating and maintaining low-level, mission-critical embedded software deployed on every Scythe mower.

You’ll work in concert with teammates across engineering, manufacturing, and field operations to design, build and maintain the vital subsystems that power Scythe's autonomous mower. We expect you to be broadly experienced to be able to “see around corners”, to thrive in a fast-paced, self-managed engineering environment, and to be a collaborative, low-ego teammate who helps Scythe realize its big mission.

What you’ll do at Scythe

  • Develop, test, deploy, and support Scythe's firmware for various mission-critical subsystems, including power management, sensing hardware management, user control interface and more
  • Contribute to system architecture design, emphasizing safety and reliability
  • Collaborate with electrical engineers for board bring-up and troubleshooting
  • Work closely with robot software engineers to ensure seamless integration of firmware with higher-level robot software

What you know well

  • Firmware development in C/C++ for microcontroller-based embedded systems
  • ARM-based microcontrollers, specifically the ARM Cortex-M series
  • Build systems like Make and CMake
  • Communication protocols such as CAN, I2C, SPI, UART, and USB
  • Debugging firmware using JTAG/SWD interfaces and GDB
  • Debugging hardware using benchtop equipment such as DMM, oscilloscopes, and logic analyzers
  • Distributed version control systems (we use Git)
  • Python and shell scripting

What you’ve maybe done

  • System architecture for complex embedded systems
  • GUI development for embedded systems
  • Software infrastructure development for automated build and test as well as in-field telemetry and failure reporting
  • Over-the-air (OTA) firmware updates
  • Hardware-in-the-loop testing
  • FPGA programming in Verilog
  • CANOpen or other CAN communication stacks
  • Programming in Rust
