Job description

Our team’s primary product: an AI harness and toolkit designed to help GIU partners develop, integrate, and deliver AI-powered application experiences. The platform provides reusable capabilities, patterns, and tooling that make it easier for teams to adopt AI while maintaining enterprise standards for quality, reliability, security, and maintainability.

As a Lead Principal Platform Software Engineer, you will serve as a senior technical architect driving design decisions across platform services, developer experience, AI integrations, evaluation workflows, and application enablement. You will work across product, engineering, and partner teams to translate emerging AI needs into durable platform capabilities.

This role requires deep platform engineering expertise, strong architectural judgment, and practical experience applying AI and LLM technologies in production-oriented environments. You will be expected to lead through technical influence, mentor senior engineers, define scalable implementation patterns, and help establish the standards by which AI-enabled applications are built across GIU.

The ideal candidate combines hands‑on engineering depth with broad systems thinking, understands how to build platforms that other engineers love to use, and can operate effectively in ambiguous, fast-moving technical domains. Deep technical knowledge of frontend technologies is strongly preferred: JavaScript, TypeScript, nodejs.
