About AIWI AIWI is an independent non-profit that exists to ensure that insiders at frontier AI companies can speak up safely and effectively when they see something that should be addressed. We do this by integrating the ecosystem of lawyers, AI researchers, AI advocacy organizations, journalists, regulators, and policymakers who can act on what they learn. About the role You will own all of AIWI's technology: architecture, implementation, deployment, security, and maintenance. Delivery will be hands-on and you will manage a budget for executing items defined on your roadmap.

The work is demanding, sensitive, and consequential; conviction in our mission is essential. Areas of Ownership Internal tooling. We operate in a highly sensitive environment.

If you are excited about designing architecture that allows air-gapping and decentralized access, this role is for you. External-facing technology. You take offerings from prototype to production end-to-end: Zero-knowledge proof solutions for anonymous coordination, interactive scenario simulators, or automated legislation trackers.
