Senior Fullstack Engineer

How you'll have impact:

• Architect a New Suite: You will be pivotal in building a brand-new product suite that spans multiple internal products and companies.
• Own the Full Vertical: You’ll design resilient backend services (Node.js/Kotlin) and consume them in rich, AI-native UIs (Next.js/React).
• Build AI-Native Experiences: From backend agents using LangChain to streaming generative UIs with the Vercel AI SDK.

What you'll do:

• Ship end-to-end features using TypeScript (Node.js/Next.js), while maintaining or integrating with services in Kotlin/Java.
• Engineer AI agents and workflows (LangChain, MCP) that integrate retrieval, memory, and tool use.
• Obsess over quality: Maintain high confidence with Playwright (E2E) and Kotest/Jest/Vitest (Unit), and continuously tune performance (latency, Core Web Vitals).

Requisitos:

• 6+ years building production software.
• True Fullstack Fluency: Deep expertise in TypeScript (React/Node.js) is a must.
• Cloud Native: Proven experience running containerized workloads in AWS, Kubernetes, or serverless environments.
