How to Apply for Embedded Software Engineer

at GridIQ

🏢 About GridIQ

GridIQ is at the forefront of combating wildfires by leveraging real-time grid intelligence. Their remote-first culture and focus on infrastructure resilience make them a compelling choice for engineers who want their work to have a tangible impact on public safety and environmental protection.

About This Role

As an Embedded Software Engineer, you will own the firmware for GridIQ's edge device, which is critical for collecting and transmitting real-time grid data. Your work on low-power state management, cellular data transport, and OTA updates will directly enable wildfire prevention and infrastructure monitoring.

💡 A Day in the Life

You might start by reviewing overnight test results from the latest firmware build, then collaborate with hardware engineers to debug a new board revision. In the afternoon, you could optimize the device's sleep/wake cycle to reduce power consumption, followed by a code review for an upcoming OTA update feature.

🎯 Who GridIQ Is Looking For

  • Has 5+ years of embedded firmware experience with at least one shipped product on bare-metal or RTOS, ideally with low-power ARM Cortex-M.
  • Proficient in C and has working knowledge of C++ in embedded contexts, with hands-on experience in Zynq or similar SoC platforms and Embedded Linux (device trees, kernel modules).
  • Experienced in cellular modem integration (e.g., LTE-M, NB-IoT) and low-power state machine design for battery-operated devices.
  • Skilled in hardware debug tools (JTAG/SWD, logic analyzer, oscilloscope) and Python for test automation.

📝 Tips for Applying to GridIQ

1

Highlight any experience with wildfire prevention, grid monitoring, or infrastructure resilience in your resume and cover letter.

2

Emphasize your track record of shipping products that involved low-power design and OTA firmware updates with integrity verification.

3

Mention specific SoC platforms you've used (e.g., Zynq, STM32, nRF) and detail your Embedded Linux work (device trees, kernel modules).

4

Include examples of collaboration with hardware engineers during board bring-up and with cloud/platform teams on device-to-cloud protocols.

5

Tailor your application to show deep understanding of GridIQ's mission; mention any personal connection to wildfire prevention or grid reliability.

✉️ What to Emphasize in Your Cover Letter

['Your passion for using technology to prevent wildfires and strengthen infrastructure.', 'Proven ability to own firmware from concept to production, especially low-power and OTA update features.', 'Experience with cellular modems and device-to-cloud communication protocols (e.g., MQTT, CoAP).', 'Your collaborative approach with hardware and platform teams to ensure seamless integration.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read GridIQ's blog or press releases about their wildfire prevention technology and partnerships.
  • → Understand the challenges of grid monitoring in remote areas and how low-power edge devices address them.
  • → Familiarize yourself with common cellular IoT protocols (LTE-M, NB-IoT) and their suitability for GridIQ's use case.
  • → Learn about GridIQ's platform architecture, particularly how edge devices communicate with the cloud for real-time insights.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a low-power sleep/wake state machine for a battery-powered edge device that periodically sends sensor data.
2 How would you implement a secure OTA firmware update with rollback capability on an ARM Cortex-M or Zynq platform?
3 Describe your experience with cellular modem AT commands, PPP, or LTE stacks. How do you handle poor connectivity?
4 Walk through a board bring-up debug session using JTAG/SWD and a logic analyzer.
5 How do you ensure deterministic behavior in an RTOS or bare-metal system while managing multiple tasks (RF acquisition, cellular, sensors)?

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume without emphasizing low-power design, cellular integration, or OTA update experience.
  • Failing to mention any shipped product experience or treating this as a pure Linux role without embedded context.
  • Overlooking the importance of collaboration with hardware and platform teams; avoid presenting yourself as a solo developer.
