Job Specifications

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 (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
