As our first dedicated Staff Application Security Engineer, you will own the design and implementation of our application security program, from SAST and DAST tooling to secure SDLC practices, threat modeling, dependency security, and penetration testing coordination. You will work directly with engineering teams across a cloud-based environment securing both customer-facing products and internal systems. You will be reporting directly to the Head of Security and will have the autonomy and organizational support to build an application security program that is practical, scalable, and aligned to the risk profile of a company operating in the digital asset space.
