• Comfortable designing APIs, microservices, and event-driven architectures; fluent working with REST, GraphQL, and gRPC.
• Strong product instincts: proven ability to interview end-users, articulate problem statements, and balance ROI vs. model accuracy.
• Bonus: experience handling regulated or privileged corpora (legal, healthcare, finance) and implementing data-privacy controls.
• Proficiency in Python for scripting, automation, and API integration.
• Hands-on experience working with REST APIs, webhooks, and SDKs.
• Experience configuring and deploying cloud-based AI services or SaaS platforms.
