Résumé du poste

Ruby Labs seeks a Senior AI Engineer to own and scale the AI layer of a core D2C subscription product. You’ll be responsible for production LLM features and browser automation, focusing on quality, reliability, and cost across the stack.

Qualifications

• 5+ years of software engineering with Node.js, TypeScript, Next.js, and Postgres, including edge/serverless runtimes such as Cloudflare Workers.
• Production experience with dynamic prompting and structured outputs in AI pipelines.
• Decision-making driven by benchmarks and observability rather than intuition.

Responsabilités

• Own production LLM features and browser automation end-to-end for a core product.
• Design dynamic prompts with context injection and conditional logic.
• Build and maintain browser automation with Playwright and Browserbase Functions.
• Ship versioned, reproducible automation and manage risk with safe rollbacks.
• Develop evaluation pipelines and AI gateway integrations for cost-effective models.
