Description

Summary: This role involves building a new product suite with a focus on AI-driven automation, spanning full-stack development and architectural leadership within a product-obsessed team. Highlights: 1. Architecting a brand-new, multi-product suite with AI-native experiences 2. Owning full vertical development from resilient backend to rich UIs 3. Driving engineering excellence, clean code, and performance optimization **Company Description** We're on a mission to make hotel operations effortless. Our cloud-native platform already powers thousands of properties worldwide, and we're doubling down on AI-driven automation to remove the busy-work from hospitality. We're a lean, product-obsessed team that values curiosity, data-driven decisions and shipping to production daily. If you love turning complex problems into elegant, resilient systems, we'd love to meet you. **Job Description** **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, tackling challenges in scalability, reusability (Monorepo), and multi-tenancy. * **Own the Full Vertical:** You won’t just hand off APIs. 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, you will bring AI into the core of the user experience. * **Drive Engineering Excellence:** Your input on architecture is expected. You’ll champion Domain-Driven Design (DDD), clean code, and performance optimization across the entire stack. **What you'll do** * **Ship end-to-end features** using **TypeScript (Node.js/Next.js)**, while maintaining or integrating with services in **Kotlin/Java**. **Craft modern frontends** with **React, Tailwind, and Vercel AI SDK**, managing complex state with **TanStack Query** and **Zustand**. * **Engineer AI agents** and workflows (LangChain, MCP) that integrate retrieval, memory, and tool use. * **Own your infrastructure:** manage deployments using **Terraform (IaC)** on AWS/Kubernetes and handle Vercel configurations for the frontend. * **Obsess over quality:** Maintain high confidence with **Playwright** (E2E) and **Kotest/Jest/Vitest** (Unit), and continuously tune performance (latency, Core Web Vitals). * **Leverage AI tooling** (Copilot, Cursor, Claude) to accelerate development and share workflows with the team. **Requirements** * **6+ years** building production software. * **True Fullstack Fluency:** Deep expertise in **TypeScript** (React/Node.js) is a must. Familiarity with **Kotlin or Java** is highly valued. * **Cloud Native:** Proven experience running containerized workloads in **AWS, Kubernetes**, or serverless environments. * **Data Polyglot:** Comfortable with both relational and NoSQL databases (MySQL, DynamoDB, Redis). * **Architectural Eye:** You understand DDD and distributed systems patterns, not just syntax. * **Communication:** You communicate clearly in Spanish / English and thrive on feedback loops. **Nice-to-have superpowers** * Experience scaling **Monorepos** (Turborepo, Nx). * Hands-on with **AI coding assistants** or agent frameworks (LangChain, Autogen). * Experience with **GitOps** or MLOps pipelines. **Additional Information** * **Remote-first culture** with flexible schedules and core hours. * **Goal-oriented work** with an amazing, agile, cross-functional team. * **Learning budget** and career plan. * An international and diverse environment where you matter.
