Overview
GENFLUX Security is a security product that makes companies' use of generative AI visible, controlled and recorded. As a frontend engineer, you develop the admin console (web and desktop) that administrators use to understand and manage how their organization uses AI. Rather than only implementing screens, this is a key position building a product that directly informs monitoring, control and audit decisions.
Why we are hiring
Elith is an AI startup spun out of the Matsuo Lab at the University of Tokyo, working on the research, development and real-world deployment of AI Safety and AI Security. Our own product, GENFLUX, is an integrated platform that supports companies' use of generative AI end to end: adoption, operation, security, quality evaluation and custom builds.
Built on the idea of combining offense and defense, the lineup includes GENFLUX FDE for on-site implementation, GENFLUX Security for making in-house AI use visible and controlled, GENFLUX Evaluation for assessing the quality and safety of AI, GENFLUX Knowledge for internal knowledge, and GENFLUX Local for running AI in closed environments.
As the use of generative AI spreads rapidly, issues such as information leaks, hallucinations and regulatory compliance are surfacing in every industry. We are looking for people to join our challenge of making Japanese technology the global de facto standard.
Responsibilities
- Designing, implementing and improving the UX of admin dashboards that directly inform operational decisions, such as AI usage and KPIs

- Beyond the frontend, you work across the whole product, including browser extensions and desktop support

Requirements

- Understanding of multi-tenant web service design and web security
Ideal candidate
- Keeps up with technology trends in frontend, security and AI and forms your own stance on which technologies and design approaches to adopt, given our product's context, constraints and customer issues
- Looks past customers' and users' surface requests to the underlying problems, and acts on your own initiative to solve them while forming hypotheses
- Stays positive in fast-changing, uncertain situations, sorts out facts, hypotheses and risks, and drives decisions and execution through constructive discussion
