• 5+ years building software in production, owning a system at scale or during a migration.
• Strong fundamentals: data modeling, APIs, performance, concurrency and failure modes.
• Experience with LLM-powered systems in production, not just prototypes.
• Comfort across frameworks like Pydantic, Agents SDK and A2A, with ability to justify choices.
• Experience with traditional ML and knowing when a model beats a prompt.
• A product you built is visible and usable.
• Fluent English and Spanish.

Responsibilities

• Build AI features that ship to students, and own them in production: performance, reliability, cost, and recovery.
• Design the orchestration behind them: agents, tools and the flow between them, built to be debugged and not just demoed.
• Make evals part of your workflow to measure improvements, regressions, and trade-offs.
• Choose the right approach for each problem, whether an LLM, a classic model, or deterministic code.
• Make architecture decisions you can defend, and resist unnecessary complexity.
• Elevate code quality through reviews, standards, and proactive decision-making.
