Founding Engineer

Liva AI is a data company building the 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.

WHAT YOU’LL DO:

• 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 (AWS) 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
