Hi there! Thanks for stopping by đź‘‹

Are you actively looking for a new opportunity? Or just checking the market? Well… you might just be in the right place!

As a Senior Application Security Engineer, you will serve as a foundational anchor on the AppSec team, leading our strategic shift hard-left toward developer-embedded security and Secure by Design operationalization. You will design, build, and scale state-of-the-art AppSec practices while collaborating closely with Vulnerability Operations to streamline vulnerability triage and remediation. Leveraging cutting-edge AI-assisted workflows and modern automation, you will eliminate friction for developers, burn down legacy risks, and fortify software lifecycles against sophisticated, emerging threat vectors.

What you’ll be doing

  • Operationalize Secure by Design principles end-to-end, embedding seamless security controls directly into feature designs, pull requests, IaC checks, and daily engineering workflows.
  • Architect high-impact feature and infrastructure threat models, validating and enhancing advanced AI-generated threat modeling pipelines.
  • Configure, fine-tune, and orchestrate SAST, DAST, SCA, Secrets, and LLM scanner rulesets to eliminate false positives and streamline Vulnerability Operations.
  • Build and stabilize new AppSec processes and ways of working while ensuring legacy security controls remain fully active.
  • Pioneer AI-driven automation to dramatically accelerate vulnerability triage and remediation, systematically burning down security backlogs.
