MTS - Platform 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 an exceptional Senior Engineer to help build the Ironsite platform.

You'll build and ship the product that turns our video data into something construction teams act on every day, including the dashboards project leaders open at 5 AM, the labor-management tools superintendents run their entire jobsite on, the mobile experience craft workers carry in their pocket, and the integration layer that connects Ironsite to the software the industry already lives in.

You'll own meaningful initiatives that directly impact tens of thousands of craft workers and dozens of the largest contractors in the country, working alongside our engineering team and technical leadership t

e.js, PostgreSQL, Redis), and cloud infrastructure (AWS). You've made real judgment calls with each and know when to reach for which.

• Experience shipping web applications at scale, in production, with the kind of reliability construction customers won't tolerate the absence of.
• Solid background in API design, third-party integrations, and real-time data and analytics surfaces.
• Systems thinking that spans end-to-end product architecture. You care about the seams between systems, not just the systems themselves.
• Typically 5+ years of full-stack product experience, with a track record of shipping meaningful things you're proud of.
• A background in Computer Science, Software Engineering, Mathematics, Physics, or a related technical field, or the equivalent hands-on experience.

Preferred Qualifications

• Deep experience owning and shipping product surfaces end-to-end, from schema through to UI, and knowing how to make the tradeoffs that come with that scope.
• Background building analytics dashboards, reporting systems, or business intelligence surfaces where the data itself is the product.
• Experience shipping mobile web experiences designed for real-world conditions.
• Genuine excitement about industries that have been underserved by software, and interest in becoming one of the engineers who builds the infrastructure the physical world runs on.
• Familiarity with construction management software (Procore, Autodesk, Trimble), HR tech, or similar enterprise workflow tools.

Location, Compensation, & Perks

• San Francisco Bay Area (on-site)
• Base salary: $160k-$230k per year, commensurate with experience
• Meaningful founding-team equity.

• Daily catered lunch
• Office in San Francisco, next to Oracle Park and the Caltrain

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