Firmware Engineer; Intermediate

What We Do

Long term: Our mission is to make modern automation tools accessible to every farm on the planet.

Right now: We build modern irrigation automation for every grower. We do that by building and deploying intelligent devices to automate farm infrastructure for irrigation, fertilization, and other operations along with the software to scalably manage it all.

You might think this is surely a solved problem. As it turns out, it isn’t even close. Especially not at the scale our customers, the world’s largest food brands, operate at. And that’s where you come in.

You'll join a small, high-ownership team building and operating battery-powered sensor nodes, controllers, and LoRaWAN gateways deployed on production farms. These devices live in the real world, getting bumped by tractors, enduring winter outdoors, and sometimes end up fully submerged in a manhole.

As a Firmware Engineer, you'll ship features on an existing products, making the system more resilient, and contribute to new product development.

You'll work primarily in ZephyrRTOS across different MCU platforms, partnering closely with EE, backend, and field ops.

• Ship production firmware on Zephyr RTOS for STM
  32 devices (feature development + maintenance).
• Build and maintain sensor integrations and field interfaces, including I2C, SPI, UART, SDI-12, RS-485, ADC, and pulse sensors.
• Improve device resilience and “field survivability”
• Own meaningful pieces of our FUOTA (firmware update over the air) effort
• Collaborate and share ownership with cloud/backend engineers on device telemetry, fleet observability, and update pipelines
• Debug real-world issues end-to-end: reproduce failures, instrument firmware, analyze logs/telemetry, and land fixes that reduce repeat incidents.
• Maintain quality and velocity through good engineering hygiene: code review, CI, unit tests, and hardware-in-the-loop.
• Occasionally support manufacturing/test needs (provisioning, flashing, simple fixtures/scripts), without it being your primary focus.

Must have

• 3+ years experience shipping MCU firmware in production, with strong fundamentals in C/C++.
• Have formal education in Electrical Engineering, Computer Engineering, Computer Science, or related field
• Able to work in-office in Vancouver, BC
• Experience integrating hardware interfaces and sensors. You must have worked with at least some, if not all of these:
• I2C, SPI, UART, ADC, pulse counting
• Industrial buesses like SDI-12/RS-485
• Comfort working at the app layer while understanding what’s happening underneath: boot flow, flash layouts, interrupts, drivers, and how to debug when “it’s not the app’s fault.”
• Collaborative mindset: comfortable pairing with EE, backend, and field ops to diagnose issues and land improvements.
• Knowledge of standard industry best practices

Nice to have

• Real experience working in Zephyr RTOS (this is a major plus for us)
• Hands-on MCU firmware experience on STM
  32 (bonus if you’re familiar with NRF).
• LoRaWAN familiarity, and ideally some exposure to FUOTA
• Cellular and/or BLE experience
• Familiarity integrating with industrial equipment via Modbus
• Experience working in cross-functional teams (mechanical, electronics, firmware, backend)

• Engineers who enjoy being close to customers and reality — People who turn “we saw it once in the field” into durable fixes
• Interest and/or experience in the agriculture/sustainability industry
• Past experience with high-growth startups

• Compensation
• Annual salary of $80,000 to $110,000
• Stock options package
• Comprehensive health benefits (dental, vision, mental health, and more)
• Flexible policies
• Flexible time-off policy (min 3 weeks vacation)
• Hybrid work schedule
• Flexible hours
• Growth opportunities
• Chance to shape a fast-growing startup and transform the agriculture industry
