How to Apply for Head of Firmware

at Base Power Company

🏢 About Base Power Company

Base Power Company is revolutionizing home energy by deploying distributed batteries that provide grid support and outage protection at a fraction of traditional costs. Their focus on high-reliability, low-cost energy storage makes them a key player in the transition to a resilient, decentralized grid.

About This Role

As Head of Firmware, you will own the entire firmware stack—from BMS MCUs to edge gateways and cloud telemetry—setting technical direction and shipping high-leverage code. This role is critical for ensuring safety compliance (UL 1973, 1741, etc.) while maintaining rapid iteration on a fleet of deployed devices.

💡 A Day in the Life

Mornings might involve reviewing critical PRs and mentoring senior engineers on architecture decisions. Afternoons could be spent writing firmware for a new BMS feature, then hopping on a call with the hardware team to debug an integration issue. You'll also block time for hiring interviews and compliance reviews.

Quantify your impact: e.g., 'Led firmware for 10k+ deployed units with <0.1% failure rate' or 'Reduced OTA update time by 50%.'

3

Showcase end-to-end ownership: describe projects where you owned firmware from MCU to cloud, including telemetry pipelines.

4

Emphasize team-building: mention how you've hired, mentored, or defined engineering levels and interview processes.

5

Tailor your resume to include keywords like 'BMS', 'inverter', 'real-time control', 'OTA', and 'embedded Linux'.

✉️ What to Emphasize in Your Cover Letter

['Your passion for revolutionizing home energy and making backup power affordable and accessible.', 'Specific examples of shipping high-reliability firmware under regulatory constraints (e.g., UL standards).', 'Your experience scaling a firmware team or being the go-to technical leader in a fast-growing company.', "Your alignment with Base Power's mission and your willingness to work in-person in Austin."]

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read about Base Power's product lineup and their approach to grid support vs. backup-only systems.
  • → Understand the regulatory landscape: UL 1973 (battery safety), UL 1741 (inverters), UL 9540 (energy storage systems), and UL 9540A (thermal runaway).
  • → Look into recent news or funding rounds—Base Power is likely scaling rapidly; know their growth stage.
  • → Check the company's technical blog or GitHub (if public) to understand their engineering culture and stack.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk me through the firmware architecture you designed for a previous product—from MCU to cloud.
2 How do you ensure compliance with UL 1973 or 1741 while maintaining fast shipping velocity?
3 Describe a time you had to debug a critical issue in a deployed fleet. What was your approach?
4 How would you hire and structure a firmware team for a company scaling from 10 to 100 engineers?
5 What's your experience with OTA update systems? How do you handle rollbacks and failure modes?

⚠️ Common Mistakes to Avoid

  • Don't be vague about compliance—if you lack direct UL experience, explain how you've worked with similar safety standards.
  • Avoid focusing only on management; this role still expects you to write code and review PRs.
  • Don't ignore the relocation requirement—if you're not in Austin, explicitly state your willingness to move.
