Senior Developer Experience (DevEx) Engineer – AI Platform

Requirements

  • 4+ years of professional software engineering experience building developer tools, internal platform infrastructure, CLI utilities, or IDE extensions in Python or TypeScript.
  • 2+ years designing developer platforms, SDKs, or developer experience (DevEx) infrastructure.
  • 1+ years of hands-on experience optimizing AI-assisted development workflows (e.g., Cursor, GitHub Copilot, Claude Code, or custom LLM coding extensions).
  • Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

Nice to Haves

  • Hands-on experience writing .cursorrules, system prompts, or context-injection pipelines for AI code editors.
  • Strong knowledge of schema definition standards (JSON Schema, Pydantic, OpenAPI) and API contracts.
  • Familiarity with the Model Context Protocol (MCP), tool-calling specifications, or agent execution harnesses.
  • Deep empathy for developer ergonomics, API design, CLI interfaces, and technical documentation.
  • Excellent technical writing skills for quick-start guides, developer documentation, and architecture standards.

What You'll Be Doing

  • Architect and maintain internal editor configurations (e.g., Cursor, VS Code) using .cursorrules, system prompts, and custom extensions to streamline AI skill authoring.
  • Develop local CLI utilities, linters, and pre-commit hooks to provide developers instant feedback on schema correctness, formatting, and syntax before pushing code.
  • Track developer friction, template adoption, and first-pass build success rates to continuously reduce time-to-publish for new skills.
  • Build function-calling abstractions, wrap existing enterprise REST APIs into MCP schemas, and maintain standard Python/TypeScript skill libraries.
  • Design and distribute standard templates, boilerplate generators, and SDKs for Model Context Protocol (MCP) tool schemas and JSON-RPC skill contracts.
  • Build local codebase indexing, RAG, and context-ingestion pipelines that supply AI editors with accurate, real-time platform documentation and API specifications.

Perks and Benefits

  • Competitive base salary range (€86,400 EUR - €129,600 EUR) with eligibility for bonus plans and annual stock grants.
  • Flexible work approach combining in-person and remote time, requiring at least 50% of time each quarter in the office or field.
  • Supportive company culture rooted in integrity, empathy, and collaboration.
  • Opportunities for professional growth with tools and skills development.
  • Reasonable accommodations provided during the application process and employment.
