Job summary

Lavendo is hiring a Product Engineer to build the core browser-automation and AI-agent tooling that developers rely on. You’ll ship end-to-end features, ensure reliability as the web evolves, and translate tough problems into clean APIs used by thousands of developers.

You will sit with the engineering team in a hybrid setup in the San Francisco Bay Area, taking ownership of features with minimal PM input and strong focus on developer experience.

Qualifications

• 3–8 years of experience in product engineering, shipping browser automation, web scraping, or AI agent tooling to external developers.
• Strong proficiency in TypeScript and Node.js (required).
• A track record of owning features end-to-end with no PM and no designer, ideally at a sub-200-person startup (Series A–C).
• Demonstrated obsession with developer experience—latency, response format, error messages, and docs as first-class design concerns.
• A bias toward shipping in days, not weeks, with comfort making calls on imperfect data and killing features that don’t work.
• Able to work hybrid from the San Francisco Bay Area.

Responsibilities

• Build and ship developer-facing features from idea to production, not backlog tickets, actual shipped product.
• Own the reliability of what you ship against a web that changes constantly and fights back.
• Turn genuinely hard, ambiguous problems into clean APIs developers love using.
• Sit directly with the engineering team on roadmap calls and the tradeoffs behind them.
• Dogfood your own product, read the GitHub issues, and let real developer pain decide what you build next.
