Senior Application Security Engineer - Resware
Remote/ Boulder, CO

At Qualia, we've built a new class of real estate technology that simplifies home buying and selling into an easy, understandable, and secure process. Our products bring together users from across the real estate ecosystem---homebuyers and sellers, lenders, title and escrow agents, and real estate agents---onto a single shared platform, providing greater clarity and transparency to real estate transactions. Today, millions of consumers use Qualia to close on homes every year.


We are looking for a seasoned engineer to lead the effort on our Resware product as part of the Application Security team. The Application Security team is responsible for application threat modeling, design and oversight of secure development practices, development of tooling for exploit prevention and intrusion detection, and educating the engineering organization on security best practices.

Security engineers need to have broad and deep technical knowledge. Security cannot be reduced down to a static bag of tricks. It requires sophisticated knowledge of how all software works and mature mental models of how to reason about the security of complex systems. Security engineers already possess the knowledge and mental models necessary to be successful in their role and are constantly working to improve them.

  • Develop tools to prevent, detect, investigate, and respond to security threats within a software environment.
  • Educate the engineering organization on security best practices by providing training and acting as a subject matter expert and mentor


  • Development experience in C#, .NET
  • History partnering with development teams to identify and address application security concerns.
  • Broad knowledge across the security domain
