Atlassian is looking to build a next-generation API Platform that requires a comprehensive system for governance, monitoring, and metering of all Atlassian APIs, including newly released Model Context Protocol (MCP) servers. This involves creating foundational features and 0-1 products to shape future developer and customer interactions with Atlassian's API ecosystem.

Requirements

  • 12+ years of backend software development experience, with at least 5 years in principal/staff-level roles.
  • Proven experience in backend software development, with a strong track record of delivering large-scale, end-to-end initiatives.
  • Experience working on 0-to-1 products, thriving in environments with high uncertainty and complexity.
  • Expertise in API design, governance, and implementation, with a deep understanding of versioning, schema evolution, and standardization.
  • Hands-on experience integrating LLMs/AI models into production backend systems.
  • Expertise in cloud platforms (AWS preferred) including serverless and container orchestration.
  • Deep knowledge of API security: OAuth, API keys, rate limiting, and DDoS protection.

Responsibilities

  • Define the technical roadmap for the API Platform organization, balancing immediate needs with long-term vision.
  • Architect consumption-based monetization systems with sophisticated metering, billing, and analytics.
  • Develop strategies and tools for AI-native features, including the Model Context Protocol (MCP), to enable seamless integration with next-generation products.
  • Drive innovation in API lifecycle management, including versioning, deprecation, and migration strategies.
  • Mentor senior engineers across the organization on API design and AI integration best practices.
  • Build and foster a culture of innovation, operational excellence, and continuous learning.
  • Work on foundational features as well as on 0-1 products that will shape how developers and customers will interact with Atlassian in the future.
