Skills
Must have
- 6+ years of hands-on experience shipping electrical designs on production hardware, with at least one full product lifecycle delivered in wearables, cameras, consumer electronics, or ruggedized hardwa
- Deep expertise in multi-layer PCB design, schematic capture, and layout for mixed-signal and high-speed designs.
- Strong experience with power system design, including battery management, charging, protection, and low-power techniques for wearable or portable devices.
- Hands-on experience integrating optical imaging systems (MIPI CSI or similar), wireless connectivity (BLE, Wi-Fi, LTE), IMU, and environmental sensors into cohesive hardware platforms.
- Experience with high-speed signal integrity analysis and design for reliable operation at production yields.
- Comfort reading schematics, datasheets, and using standard hardware lab tools (oscilloscope, logic analyzer, network analyzer, thermal camera, protocol analyzers) to debug hardware and hardware-softwa
- Systems thinking across the full hardware stack. From silicon and PCB through mechanical integration and firmware, you understand how electrical decisions propagate throughout the product.
- Experience working directly with contract manufacturers on hardware bring-up, DFM, DFT, and production ramp.
- A background in Electrical Engineering, Computer Engineering, or a related field, or the equivalent experience.
Nice to have
- Familiarity with contract manufacturers in Taiwan, mainland China, or Southeast Asia.
- Experience with FCC, CE, or other regulatory certification processes for wearable or wireless devices.
- Experience with prior electrical engineering leadership at a hardware startup that scaled from early volumes to full production.
- Mandarin or Vietnamese language proficiency.
- Familiarity with mechanical CAD tools (SolidWorks, Fusion 360) for cross-functional collaboration.

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.
