• Define the technical roadmap for AI agent and tool integrations in C++ development workflows.
• Help establish alignment and trust across engineering, AI, Product, QA, ML, and broader ecosystem teams.
• Explore how coding agents can leverage IDE capabilities, development context, and specialized tools to work more effectively with complex codebases.

Requirements:

The ideal candidate is a highly experienced technical leader who combines strong software engineering expertise with hands-on experience building AI-powered products and the ability to influence technical direction in rapidly evolving environments.

• Significant software engineering experience at Staff Engineer, Principal Engineer, Technical Lead, or a comparable senior technical level.
• Strong experience with Kotlin, Java, or other JVM technologies, or the ability to quickly become productive in a JVM-based codebase.
• Experience building AI-powered products, developer tools, coding assistants, agents, or LLM-based workflows.
• Strong understanding of modern coding agents, including tool calling, context management, MCP, and AI evaluation techniques.
• Proven ability to drive technical direction in ambiguous, complex, and rapidly evolving areas.
• Strong product judgment and the ability to balance experimentation and innovation with practical delivery.
• Excellent communication and collaboration skills, with the ability to influence stakeholders without formal authority.
• Experience with C++ development workflows, compilers, debuggers, language tooling, or developer productivity products is a strong advantage.
