About Us Domalytx is reimagining the future of home inspections by combining deep field expertise with cutting-edge technology. Founded and built by civil engineers with over 15 years and 5,000+ inspections under their belt, we know the real problems inspectors face and the level of accuracy homeowners and buyers demand. Headquartered in Silicon Valley, we bring a technology-first mindset to an industry that has long lagged behind in innovation. Our platform transforms inspections from a slow, manual process into a streamlined, AI-assisted experience where inspectors can simply walk, talk, and capture photos while the software generates clear, professional reports. Backed by our leadership in foundation, structural, seismic, and drainage inspections—the most complex and high-stakes areas in residential real estate—we are uniquely positioned to become the trusted standard for property condition reporting nationwide. Joining Domalytx means being part of a team that’s not just modernizing inspections, but building the platform that will define how homes are evaluated, bought, and maintained for decades to come. The Role We’re looking for an Industry Partnerships & Data Acquisition Lead to help us grow the network of professionals contributing to our platform. You won’t do this alone. You’ll be partnered with an industry veteran (engineer/inspector) who can jump in for credibility, sit in on Zoom calls, or join in-person meetings when technical authority is needed. You’ll drive the outreach and relationship-building; they’ll provide subject matter expertise when needed. This isn’t a traditional sales or data role.

What We Offer • The chance to pioneer a role in a massive, untapped industry. • Direct mentorship from founders and collaboration with industry experts. • An industry partner at your side for credibility and support. • Competitive compensation with upside as we grow. • Remote flexibility, with occasional in-person visits depending on geography. • A mission-driven company improving how millions of homeowners make decisions. Why Join Now? No one in this industry has done this before. You won’t be plugging into a machine — you’ll help design it. If you want to be the first of your kind in a growing startup, and if you’ve got the hustle and curiosity to make it work, we’d love to hear from you. How to Apply Send us your LinkedIn profile, resume, a note about why this role excites you and share an example of a time when you had to hustle to convince someone or build a relationship from scratch.
