Senior Firmware Engineer

Senior Firmware EngineerDrover is building a virtual fencing ear tag for cattle, and the platform around it to run the modern ranch. Fencing is one of the oldest unsolved problems in agriculture. Ranchers spend billions of dollars a year building and maintaining physical fences, and every fence line locks land into a grazing pattern it wasn't made for. Virtual fencing is changing that, a generational shift in how ranches are run, bringing precision and productivity gains to an industry that has to feed a growing population with fewer resources.But every system on the market today requires a collar: bulky, infrastructure-dependent, and built around electric shock. We're taking a path the industry thought impossible. We've shrunk virtual fencing into the ear tag, the form factor every cattle producer on earth already uses. Our tag combines low-power GPS, cellular and satellite connectivity, embedded sensing, solar power, and patent-pending muscle stimulation that guides cattle directionally rather than shocking them. Ranchers tag their cattle once and immediately start running their operation from their phone.We were founded by Callum Taylor (Harvard, EE & fifth-generation ranching family) and Samuel Aubin (USYD, CS), who both grew up in Australian ranching towns. We built a working ear tag and a patent-pending stimulation method in twelve months (five times faster than competitors), and are now scaling manufacturing to put the technology on every head of cattle in the USA, Australia, and New Zealand.We closed an oversubscribed seed round, signed a top-tier contract manufacturer, and are on track to launch commercially in Texas in Q1 2027.We're headquartered in Austin, Texas.As our senior firmware engineer, you will be working at the intersection of software and hardware on systems which are tested in some of the world's most perilous environments (on bulls in Montana, for instance).Because we are an early-stage startup, you will have high levels of ownership in what you build. You will play a pivotal part in the development, monitoring, and architecting of the low-level firmware on our devices. We are looking for someone who is excited about joining us at our trial ranches, interacting with our cows, and getting their boots dirty.The role is on-site at our East Austin office, with some travelling to our field office in Lockhart.What You'll DoHelp lead the embedded firmware development of a low-power cellular-connected IoT deviceWork across the company to define features and refine firmware architectureWrite, test, and QA production codeImplement and maintain a reliable, fail-safe over-the-air firmware update procedureDevelop proof-of-concept prototypes using development kits and other prototyping toolsWork closely with our electrical engineering team to perform component selection and board bring-upWork with OEM (domestic or overseas) to provide software support during engineering testing and manufacturingSupport the founding team across all aspects of early-stage development — this is a startup!Requirements5+ years of experience designing embedded software for consumer or commercial electronicsFluent in C, including testing and debuggingExperience developing firmware for memory-constrained microcontrollers (e.g., ARM Cortex-M series)Experience designing low-power connected devicesExperience with an RTOS and multi-threadingExperience with serial protocols (UART, I2C, SPI)Experience with hardware interfaces (PWM, ADC)Experience with Cellular and BLENice to haveFamiliarity with logic analyzers and oscilloscopesFull-stack experience (Python, Node)Bachelor's or Master's degree in Computer Science, Software Engineering, Electrical Engineering, or a related fieldNote: Even if you don't have all of the above and still think you're an excellent candidate for this role, please reach out.
