Job Description

Seal Security is a rapidly growing cybersecurity startup building an AI-powered AppSec engineer that works as another member of your team. Instead of the painful cycle of triaging vulnerabilities, creating tickets, and spending engineering hours on library upgrades, Seal automatically remediates open-source vulnerabilities with fully compatible, standalone security patches - no version bumps, no dependency headaches.

We're backed by top-tier VCs, led by world-class cybersecurity and GTM experts, and recently closed our Series A funding, with numerous Fortune 500 customers.

We are looking for a Senior Software Engineer who thrives on solving complex challenges across the entire stack. As a key member of our R&D team, you'll own features end-to-end - from backend services and infrastructure to frontend interfaces and developer tooling - leveraging the latest advancements in LLMs to push the boundaries of innovation.

If you're a versatile engineer who's passionate about driving innovation, wearing multiple hats, and delivering world-class products, we'd love to meet you!
