G2i Inc. Tech Stack

AI talent marketplace and model training workflows for frontier labs

Software Development Miami, Florida 201–500 employees Founded 2016 Privately Held

G2i operates three interconnected business units: a senior engineer placement service (g2i.co), an in-house AI training and evaluation platform (g2i.ai), and a code orchestration tool (orc.ai). The tech stack is polyglot and production-focused (Java, Go, Rust, Python, TypeScript, React Native) with heavy investment in evaluation infrastructure (Pinecone, Weaviate for embeddings; pytest, JUnit for testing). Hiring is nearly all engineering (39 of 41 recent roles), split senior/mid-level, across eight countries—a signal of both scale in execution and pressure to staff fast-growing RLHF and code-generation pipelines.
