Job description

Parallels is seeking a highly motivated and talented Application Security Engineer to join our team. In this role, you will make security decisions that impact millions of our customers while gaining hands‑on experience in exploit development and CVE discovery. The ideal candidate will combine an attacker mindset with the humility and detail‑oriented attitude required to coordinate fixes and security architecting with busy engineers.

Your primary responsibility will be to coordinate with more senior members of our team to write exploits and design fixes for existing application vulnerabilities. You will also help search for new critical / high risk vulnerabilities in our codebase. In addition, you will assist in vulnerability disclosure processes and help implement repeatable secure development practices.

As issues are uncovered, you will communicate with the appropriate technical and leadership teams to ensure a focus on risk mitigation – allowing for business continuity, but without negligent risk. Application security engineers are constantly assessing applications for weaknesses and finding resolutions before they can be abused.

Parallels: anytime, anywhere, any-device productivity.

Why Parallels, why now?

The top creative and technical minds could sell anywhere. So why are so many choosing Parallels? Three reasons:

This is the moment. It's an exciting time at Parallels — strong leadership, a refreshed brand, and a whole new approach to how the world works. The EUC market is shifting fast, and we're at the front of that wave. We want you riding it with us.

We want you to be you. Too many companies tell you about their culture and then expect you to fit it. Ours is built from the people who work here. We want you to feel safe being who you are, taking risks, and showing us what you've got.

It's your world. We know you have a life. We want to be part of it — not all of it. At Parallels, we're serious about empowering people to work when, how, and where they want. Couch? Sweatpants? Cool with us. Happy sellers mean happy customers. That's why we hire amazing people and get out of their way.

Sound good so far? Awesome. Let's talk about the role
