As part of Liva’s engineering team, you’ll have end-to-end ownership over projects that define how frontier AI data is collected, validated, and quality-assured. You’ll work on a mix of platform engineering and infrastructure development (scaling data platforms, building human-in-the-loop systems, designing evaluation pipelines).

You might build a mobile app for data collection one week, design an automated QA pipeline with intelligent validation systems the next, and then improve our annotation platforms. You’ll also play a key role in developing AI agent–driven workflows that automate core operations.

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
• Participate actively in code reviews and technical design discussions
• Contribute to the core infrastructure powering data collection and quality assurance for leading AI labs

REQUIRED SKILLS:

• Super fast at shipping
• Can flexibly learn and adapt to new tools/goals
• Strong coding fundamentals in Node.js / TypeScript, Python, and React/Next.js
• Experience building web applications and ideally mobile apps
• Familiarity with AWS, databases, and API design
• Strong communication skills and a bias toward ownership, curiosity, and delivering simple solutions to complex problems
• 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
