Key skills for this role
We’re building a search engine for human thought .
While you might go to Google to search through the web, you come to Terac to search through human opinion . Consumer research teams at DoorDash, Notion, and Posh use Terac to test features and products before launch. Our AI-native researcher recruits the right panelists, conducts real voice interviews, and delivers transcripts and insights within hours—not weeks.
We’re solving a once-in-a-generation problem at the frontier of Voice AI, memory systems, and large-scale data matching . As the world races to automate engineering, the real bottleneck is understanding what to build and who to build for. Terac exists to fix that.
We started 5 months ago and have already raised $9M, built an in-house AI panel of thousands, and launched pilots with major consumer companies. Joining now means being part of the founding team defining the next $100B market.
We’re looking for a founding engineer who wants to own huge pieces of the product, move fast, and help build the future of human understanding.
You’ll work directly with our CTO to design, build, and scale the core systems behind Terac, from our sourcing algorithms and interviewer agents to our panel data pipelines and researcher tools.
This is not a “feature factory” role. You’ll ship end-to-end systems, debug live customer interactions, and shape the company’s engineering DNA from day one.
