• Leverage AI-powered development tools to improve productivity and accelerate delivery

• Build and ship high-quality, production-grade software using modern engineering practices, with AI as a core part of your development workflow by pushing the boundaries of AI development tools to deliver secure, optimized, and high-quality code.
• Design and orchestrate complex systems where AI agents integrate seamlessly into human workflows, driving efficiency and innovation at scale.
• Contribute to building and maintaining the shared system context, an explicit repository of system designs, constraints, and standards that enables AI to operate accurately and reliably.
• Critically evaluate code (human or AI-generated) for correctness, quality, security, and performance.

Required Qualifications

• 5+ years of experience or 6+ years in software development

• Experience with testing frameworks, quality engineering practices, and automation

• Ability to lead initiatives, manage multiple priorities, and deliver in a fast-paced environment

• Strong communication skills with the ability to influence, mentor, and communicate risks effectively

• A demonstrated, genuine AI-first approach to engineering — using AI to move faster, build fluency across the stack, and contribute well beyond your core specialty.
• Experience using AI tools (e.g., Claude Code, GitHub Copilot, Codex, Cursor, etc.) in development workflows.
• Advanced prompt engineering skills and the ability to write precise, structured prompts and cultivate the system context that makes AI outputs reliable, secure, and production-ready.
