Senior Software Engineer, Security
San Francisco, CA

At Qualia, we are fundamentally transforming the way real estate professionals, lenders, and homebuyers manage real estate transactions, one of the nation’s largest industries. We are bringing together everyone involved in the closing process onto one shared, secure platform -- basically, we’re making buying a home in America easier, safer, cheaper, and less painful by moving the process online! Qualia was founded in 2015 by Forbes 30 Under 30 Award recipients Nate Baker, Joel Gottsegen and Lucas Hansen. The company is backed by top investors including 8VC, Bienville Capital, Menlo Ventures and Tiger Global and currently processes 15% of all US real estate transactions. Qualia is headquartered in San Francisco, CA and has offices in Austin, TX.

Our security team is responsible for ensuring the security of both our technology and our organization as a whole. The team is responsible for application threat modeling, active penetration testing, design and oversight of secure development practices, development of tooling for exploit prevention and intrusion detection, and educating the organization on security best practices. More concisely, the security team is responsible for making sure the “bad guys” don’t win.

We take security extremely seriously and do not drag our metaphorical feet on it. Yes, sometimes taking proper security measures can seem onerous or paranoid. But we’ve got our priorities straight.

As a senior security engineer, you will both directly work on object-level security challenges and also help create meta-level security principles to guide the organization as a whole. You are expected to have “been around the block” but to also keep up-to-date on novel developments in the security industry. You will be a mentor to engineers across the entire team.

Senior 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. Senior security engineers already possess the knowledge and mental models necessary to be successful in their role and are constantly working to improve them.

About our engineering team

  • Our engineering team demonstrates and values technical thought leadership.
  • Qualia hosts the official Meteor Developer’s Night in our San Francisco HQ, which is the largest gathering of Meteor developers in the world. The event features talks on Meteor and Javascript development generally, often including talks from Qualia team members.
  • Qualia’s Head of Design, Jack Lukic, is the creator of Semantic UI, one of the most popular open-source design frameworks. Qualia engineers learn this framework, and design patterns more generally, directly from the creator of the framework our front end is built on! Very few companies can say that.
  • As part of our focus on continual learning and development, a Qualia team member gives an educational talk on something they’re interested in every Thursday to the entire engineering and product team. Topics range from Kolmogorov complexity theory to the definition of art, to models of existential risk.
