• Develop reusable AI skills, prompt templates, and structured workflows for common development tasks.
• Package AI capabilities into modular, documented, and easy-to-use assets that can be shared across teams.
• Improve developer productivity by reducing repetitive tasks and simplifying access to technical knowledge.
• Create documentation, examples, templates, and guidelines that encourage adoption and gather internal feedback.

• AI & MCP Focus: Strong software engineering background with practical knowledge of the Model Context Protocol (MCP), including building or integrating MCP servers, tools, or clients.
• Frontend & Design Systems Experience: Strong background in frontend development, ideally with experience working closely with or around Design Systems, component libraries, or UI frameworks.
• Seniority & Experience: Middle/Senior level, with approximately 5 years of professional software engineering experience.
• AI Workflows: Experience designing and implementing reusable prompts, AI skills, agent instructions, or AI-powered workflows into software development processes.
• Architecture & Delivery: Ability to package technical capabilities into modular, documented solutions that other developers can easily adopt, backed by solid API integration skills and clean modular design.

Requisitos valorables

• Familiarity with LLM APIs, tool calling, structured outputs, and context management.
• Experience with TypeScript/JavaScript and modern web development ecosystems.
• Experience with developer platforms, CLI tools, internal tooling, or automation.
