AI-Native Full Stack Engineer

Description

Summary: Join a mission-driven startup to design and build full-stack systems from scratch, leveraging AI to shape product development and engineering practices. Highlights: 1. Core builder shaping product and engineering with AI 2. High-ownership, low-structure startup environment 3. Mentorship, learning, and growth potential with founders **Locations: Colombia only (remote)** **Contract: Part time** Come join us at Odisea Cultura and work with some of the most exciting start\-ups in the US ### **The Role** Our client, Yia, is looking for an AI\-native full stack software engineer to join the team as a part\-time contractor at the ground level with the potential to grow into a full time engineer position. ### **About Yia** Yia is on a mission to help small business owners everywhere leverage the latest AI technology to grow their business and deliver better services to their customers. This is a unique opportunity to contribute to a mission\-driven startup at a pivotal, foundational moment. ### **What You'll Do** You'll be a core builder, helping take the product from 0 1\. This is a greenfield environment where you'll shape not just what we build, but *how* we build it using AI. Working closely with the founder and CTO, you will: * Design and build full\-stack systems from scratch, owning features end\-to\-end from idea to production * Operate as an AI\-native engineer, using tools like Copilot, Gemini, Cursor, Claude and agent\-based workflows as a core part of development, focusing more on architecture, logic, and outcomes * Rethink traditional development workflows using AI, including debugging, testing, documentation, and code generation * Rapidly prototype and ship features, turning ambiguous ideas into working product in hours or days * Design and implement core product systems, including APIs, authentication, onboarding, and payment flows with a focus on simplicity for small business users * Continuously evaluate and integrate new AI capabilities, identifying where agents, automation, or LLM\-powered features can create leverage in both the product and internal workflows * Establish modern engineering practices from day one, optimized for speed, iteration, and maintainability in an AI\-augmented development environment * Collaborate in a high\-ownership, low\-structure startup environment, where you're expected to take initiative, challenge assumptions, and move fast without waiting for perfect specs ### **What We're Looking For** We are looking for problem solvers. We want self\-driven individuals that can take ambiguity in any area and create structure in order to build solutions to ever\-changing problems. ### **Required Skills \& Experience** Core Tech Stack * Expert level in at least one programming language. * Node.js (specifically for OpenClaw gateway management). * LangGraph (Mandatory for stateful orchestration) or CrewAI. * PostgreSQL with pgvector or Supabase (for cross\-channel identity resolution). * Docker (for sandboxing agents) and GitHub Actions. * Ability to break down ambiguous problems into structured prompts, workflows, or tasks that AI tools can effectively execute AI Integration (Workflow Essentials) * Agentic Orchestration: Experience building multi\-agent loops that include 'self\-correction' and 'tool\-calling.' * Model Context Protocol (MCP): Experience using MCP to connect LLMs to local data and third\-party APIs securely. * Ability to debug, test, and validate complex systems, ensuring reliability and clean integrations across services. Proficiency in LangSmith or Arize Phoenix for debugging agent 'thought' patterns. * API Mastery: Deep experience with Anthropic (Claude 3\.5 Sonnet) and Tavily AI. * Experience working in AI\-augmented development environments, using tools like Copilot, Cursor, Claude, or similar to significantly accelerate development * Strong judgment when working with AI\-generated code — able to review, validate, refactor, and ensure production\-quality outputs ### **Why Join Us** * **Mentorship \& Learning**. Work directly with founders * **Flexible Engagement**. Part\-time, contract\-based role with easy\-on/easy\-off structure * **Growth Potential**. Opportunity to evolve into a longer\-term role as the company secures customers * **Mission\-Driven Work**. Build technology that helps small business owners This is a **part\-time contract** role, based in Colombia, ideal for someone excited to support a meaningful mission on a flexible basis. As we grow, and based on your success, this position has the potential to become a full\-time engineer role.
