• You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
• You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.
• You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.

• You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.

• Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
• Proven experience designing and operating large-scale, low-latency distributed systems, with deep expertise in availability, fault tolerance, consistency, and cloud-native microservices (AWS preferrable, GCP, or Azure)
• Expertise in LLMs and production AI/ML infrastructure, including orchestration frameworks, inference systems, and full-lifecycle pipeline operations
• Demonstrated track record of cross-organizational technical leadership, driving architectural decisions, mentoring teams, and shipping production-grade services
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field, backed by a solid foundation in core computer science principles
