About Opsin

At Opsin, we’re enabling enterprises to adopt GenAI securely. Our vision is to become the security platform for GenAI, much like Zscaler has become for cloud security. Here’s a bit more about us:

• What we do: Our product orchestrates security measures for enterprises adopting GenAI. You can find more details about our work and progress in this document.
• Funding and traction: We raised $3M in pre-seed funding in June 2024.
• Team: Our team includes MIT alumni, former Abnormal Security engineers, and a previously successful startup founder. We initially worked with overseas contractors and have recently started building our core team in the Bay Area.
• Open roles: We’re currently hiring three Staff/Senior Engineers.

In this role, you’ll face exciting challenges, including integrating, ingesting, and processing hundreds of millions of documents for enterprises. A key challenge will be ensuring Retrieval-Augmented Generation (RAG) systems maintain the right level of security, protection, and PII scrubbing. You’ll own and build a scalable data system and search stack to solve these complex problems. It’s a high-ownership position with substantial impact.

Projects you’ll be working on:

1. LLM security layer
2. Context-based roles and permissions
3. Optimizing for performance and latency to enhance tool adoption by engineering teams
