• Strong understanding of distributed systems, event-driven architecture, SQL, asynchronous programming, automated testing, and production debugging and observability.
• Ability to make pragmatic architectural decisions that balance scalability, reliability, maintainability, and delivery speed.
• Experience serving as a senior technical engineer or technical lead on a team and influencing technical direction without formal management authority.
• Ability to take an ambiguous or moderately scoped problem, develop a technical approach, make sound tradeoffs, and drive implementation and delivery.
• Strong ownership mindset and concern for the quality, reliability, maintainability, and long-term health of shipped work.
• Judgment to decide when to act independently and when to seek broader architectural or organizational expertise.
• Hands-on fluency with AI development tools such as Claude Code, GitHub Copilot, or similar tools.
• Experience using AI in day-to-day engineering work, including coding, debugging, research, code analysis, and problem-solving.
• Ability to identify ways AI and automation can improve engineering workflows, team leverage, and quality.
• Curiosity about emerging AI capabilities and willingness to experiment and turn useful practices into repeatable team workflows.
• Track record of mentoring engineers and raising the technical capability and confidence of colleagues.
• Ability to communicate technical decisions and tradeoffs clearly with Engineering, Product, QA, and other partners.
• Continuous-improvement mindset and willingness to challenge existing practices when better ways to build, test, operate, or deliver software are available.
• Collaborative approach to technical leadership, including driving decisions while seeking input and bringing others along.
