This newly formed civilian team focuses on engineering and deploying xAI's AI capabilities (models, APIs, tools, and integrations) for international government agencies, regional/local administrations, and public sector workflows worldwide
We're building the bridge to responsible, high-impact AI adoption
Team members can expect opportunities for travel and international assignments, with work primarily in the Americas, Asia, and the Middle East
You'll work closely with product, research, infrastructure, and legal/governance teams to make Grok and future models maximally useful for global civilian missions while upholding safety, transparency, and ethical standards
Design, build, and optimize integrations between xAI's frontier models (e.g., Grok family) and international government systems, platforms, and data environments
Develop secure, scalable solutions for use cases such as policy analysis, edtech, scientific research support, public health modeling, regulatory workflows, and citizen-facing services across diverse global contexts
Collaborate on custom SDKs, APIs, developer tools, and documentation tailored for international government and enterprise developers
Partner with international agency stakeholders to understand requirements, prototype solutions, and iterate rapidly based on real-world feedback, including during on-site assignments
Contribute to safe deployment practices, including red-teaming, bias evaluation, output filtering, and explainability features for high-stakes non-classified applications in varied regulatory landscapes
Fine-tune and adapt xAI models for specific international government use cases, incorporating custom guardrails and evaluation frameworks to ensure alignment with mission objectives and ethical guidelines
Work cross-functionally to refine xAI products for public sector reliability, compliance (e.g., international standards like GDPR considerations or equivalent), and usability
Ship production-grade code and features with a bias toward speed, simplicity, and measurable impact
