• 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.

Desirable Requirements

• Experience working with AI coding assistants and agent-based development workflows
• 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
