• Must have proven experience in building and deploying scaled AI systems in production environments.
• 10+ years of software engineering experience with a deep architectural background in scalable server-side applications.
• Passion for coding at the POC level: You still love to get your hands dirty with code, but your focus is on rapid prototyping, evaluating new technologies, and building Proofs of Concept to guide the engineering teams.
