Sr. Electronics Engineer

The posting, as Ironsite Ai wrote it

About Ironsite

Ironsite is building the intelligence layer for the physical world. We design our own wearable hardware, deploy it alongside craft workers, and transform a shift's footage into a next-morning report. Our internal team and purpose-built models label the data overnight and deliver actionable insights to superintendents by 5 AM.

We are accelerating the speed, efficiency, and predictability of construction, especially for complex, mission-critical infrastructure projects, including data centers, LNG facilities, sports stadiums, hospitals, and other large-scale developments, by training AI models on egocentric construction footage and labor productivity data. We are built with a pro-worker philosophy at our core: we believe technology should empower the workforce, not replace it. We're working to give craft workers and project leaders better visibility into what's happening on-site, while creating a system where the reality of construction and the chaos of each day are finally available to the people running the project.

Ironsite is deployed across several of the largest active construction projects in the country. To date, we've captured more than 100,000 hours of construction footage across seven states, now process thousands of hours of site activity every day, and maintain a worker opt-out rate below two percent. This is enabled by a workforce-first architecture that anonymizes devices, captures no audio, and never releases raw video.

Ironsite is backed by leading investors (8VC, South Park Commons, Saga Ventures) and prominent operators across technology and construction, including Eric Schmidt, Jeff Dean, Jeff Rothschild, Mark Leslie, Scott Wu, Eric Glyman, Karim Atiyeh, Russell Kaplan, and others, alongside over a dozen construction industry operators who have joined us as partners in building this.

Longer term, we believe Ironsite is the foundation for what construction becomes in the next decade. The systems we're building will be the operating system for how the physical world gets built. We see a future where craft workers are more valued, more visible, and better paid for the skill they bring, and where the industry finally has the intelligence layer that makes autonomous construction possible. Both start with the same foundation.

The Role

We're hiring a Senior Electronics Engineer to design the electrical architecture of Ironsite's wearable hardware.

This is a critical role on the hardware team. You'll design and validate the PCBs, power systems, and multi-sensor integration that make Ironsite's devices work reliably on active jobsites, on ruggedized wearables operating in some of the harshest environments in American industry. Power efficiency, sensor performance, thermal behavior, and integration density are all electrical engineering problems in this role. If the hardware architecture doesn't hold up, nothing else does.

You'll work directly with mechanical engineering, firmware engineering, manufacturing, a

ements to a current or upcoming hardware revision.

• First 6 months. You've owned a major electrical engineering initiative end to end, whether it's a next-generation hardware bring-up, a power architecture redesign, or a sensor integration that materially improves what our devices can do. Your work is shaping what ships next.
• First 12 months. You're the internal authority on electrical engineering at Ironsite. Our hardware is more capable, more reliable, and more manufacturable because of you. When we scale from thousands of devices to hundreds of thousands, we do it because the electrical architecture you designed holds up.

Location, Compensation, & Perks

• San Francisco Bay Area (on-site)
• Base salary: $225k-$300k per year, commensurate with experience
• Significant early-stage equity
• Full benefits including health, dental, vision, and 401(k) with 6% match
• Daily catered lunch
• Office in San Francisco, next to Oracle Park and the Caltrain

Final compensation is determined by experience, location, and level.

Why This Role

Every category-defining hardware company has an electronics engineer who was the reason the hardware actually worked. Not because they had the cleverest circuit, but because they cared obsessively about the last 2% of power efficiency, the reliability edge cases at scale, and the manufacturing details that separate a product that ships from a product that gets returned.

Ironsite is at that moment. We have the product, the customers, the funding, the manufacturing partnerships, and a hardware roadmap that scales into hundreds of thousands of units. What we need is the electrical engineer who is going to design the hardware architecture that lets us get there.

If you've spent your career shipping electrical designs on wearables or ruggedized hardware at volume, and you're ready to do it again on a product that matters more than most, we want to talk.

Compensation
The base pay range for this role is $225,000 – $300,000 per year.
