We are seeking a forward-thinking and highly technical Security Architect to lead the secure design and implementation of our next-generation platforms. As the technology landscape rapidly evolves, this role is critical in ensuring our adoption of artificial intelligence, cloud infrastructure, and modern developer workflows remains both secure and agile. You will act as a key business enabler, partnering closely with engineering teams to embed security seamlessly into the development lifecycle while managing emerging risks in AI and multi-agent architectures.
