AI-Native Full Stack Engineer

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.
