Project description

Our Video Collaboration products help companies stay connected and can be found in the conference rooms of some of the biggest businesses in the world. We are a small nimble group and we are growing our team. We create amazing experiences in the conference room using creative design, surprising science, and innovation. We love what we do because we are passionate about connecting people and we use the products we create every day to stay connected to our team.

We are looking for a Senior Device Security engineer who is interested in working across the entire technology stack; from device hardware, firmware, through mobile applications, communication protocols, and into back-end cloud software and infrastructure. We don't require 'full stack experience', but we do expect you to be a subject matter expert in at least one area.

Ideal candidates can come from many different backgrounds — you may be a software engineer who is passionate about security, a bug bounty researcher, have already worked in product security teams, or you've had experience working as a security consultant.

Product Security goes beyond finding and eliminating security vulnerabilities in our products; we want to stop them occurring in the first place. As a team, we're passionate about root cause analysis; training and awareness; driving security in product road maps; and improving on core frameworks, infrastructure or detection tooling.
