• Practical experience deploying production-grade AI, ML, or LLM solutions with a focus on safety and observability.
• Fluency in English with excellent written and verbal communication skills for explaining complex architecture to business stakeholders.
• Ability to work independently in fast-paced, ambiguous environments while proactively owning problems.
• Strong collaboration skills to guide distributed engineering teams without formal authority.
• Comfort working asynchronously across time zones in a fully remote setting.
