Founding Engineer

Liva AI is a data company building multimodal datasets that make AI feel truly human. We’re building a factory of consumer-facing software designed to capture naturally occurring voice and video data at scale. We believe multimodal models will become the primary interface for human–computer interaction, yet a massive and rapidly growing data gap stands in the way. We’ve raised a $3M seed round (backed by YC, Amino Capital, CRV, angels from OpenAI and Meta, and more). We’re working with leading AI labs and voice-agent companies and have sold a wide variety of high-demand datasets. As a member of our engineering team, you’ll own end-to-end systems for collecting, validating, and quality-assuring frontier multimodal data. This includes building data collection products and annotator workflows, as well as scaling the infrastructure and evaluation pipelines. Responsibilities Design and build data collection platforms: web apps, mobile apps, and annotation interfaces Build robust QA pipelines with automated validation, quality checks, and error detection systems Lead the automation of key operational processes Contribute to the core infrastructure powering data collection and quality assurance for leading AI labs Required Skills Experience building scalable, performant full stack applications in production environments Strong proficiency in Node.js/TypeScript, React/Next.js, and Python Familiarity with cloud infrastructure and services (GCP) and Docker A proactive mindset, comfortable iterating quickly based on user feedback Bonus: Experience with annotation platforms, data labeling tools, human-in-the-loop workflows, or mobile app development Benefits Daily lunch & dinner covered Free gym membership Health insurance Opportunity to be an early member of a fast growing YC-backed startup #J-18808-Ljbffr Liva AI
