Sr. Application Security Engineer
$170k - $220k USD
Material Security is a security company, which means the bar for our own application security is exceptionally high. We are looking for a Senior AppSec Engineer who is a "builder" first. You won't just be pointing out vulnerabilities; you will be writing code to eliminate entire classes of bugs.
In this role, you will have a high degree of autonomy to shape our security culture. You’ll spend your time partnering with engineering to ensure we’re building products and systems the right way and building internal tools that make it easier for our engineers to move fast without sacrificing safety. If you enjoy diving deep into complex codebases and building infrastructure that scales security, we want to talk to you.
Responsibilities
Lead AppSec Strategy: Own the end-to-end security of the Material application, from design and threat modeling to deployment.
Vulnerability Management: Secure our dependency supply chain while working directly with engineering.
Build Security Tooling: Develop internal automation to detect and block abuse patterns and streamline security workflows (e.g., JIT access, dependency scanning).
Code & Architecture Review: Perform deep-dive security audits and code reviews for new and existing product features.
Infrastructure Security: Partner with the infrastructure team to harden our Kubernetes deployments and cloud environments (GCP).
What We’re Looking For
Technical Depth: 5+ years of experience in application security, including significant time spent writing and reviewing code.
Software Engineering Skills: Proficiency in more than more than one major coding language. Preferably (but not required), that set would include Javascript/Typescript. You should be comfortable contributing directly to the codebase.
Cloud & Containers: Practical experience securing cloud environments (GCP preferred) and a strong understanding of Kubernetes security.
Systems Thinking: A deep understanding of identity and access management (SAML, OAuth, IAM) and how to protect sensitive data at rest and in transit.
Pragmatism: The ability to balance security risks with business velocity. You should be able to propose creative "middle ground" solutions that reduce risk without blocking progress.
Versatility: A willingness to jump into areas adjacent to traditional AppSec—e.g data analysis in BigQuery or learning about protecting against prompt injection —to get the job done.
