About the Team

We are building a new AI team within Engineering, tasked with driving AI adoption across 1GLOBAL. The team’s mission is to make AI a practical, governed, and well-supported capability for every part of the company, from the engineers writing our software to the operations teams running the business. Beyond the internal platform, the team will contribute AI-powered capabilities to our commercial product lines. 

This is a foundational hire. As one of the first engineers on the team, you will work alongside a dedicated product manager and engineering team lead to set the technical direction, make early architectural decisions, and build the systems that the rest of the AI function will grow on.

• Desing and build central AI platform development and governance: AWS Bedrock fronted by an LLM gateway (LiteLLM, Portkey, or similar). Token budgets, rate limits, key management, guardrails, audit logging, observability, cost controls. 
• Engineer the technical architecture of 1GLOBAL’s internal AI tools and MCP servers, including RAG pipelines, vector search, LLM integration, and conversational interfaces. 
• Build secure ingestion and indexing pipelines for internal knowledge sources (Confluence, SharePoint, document repositories, internal APIs) with appropriate access controls. 
• Develop backend services and APIs that expose AI capabilities to internal users and, over time, to product teams building customer-facing features. 
• Establish engineering standards for the AI function: testing, deployment, monitoring, and model evaluation frameworks.
