– How are lasers and quantum-mechanical tunneling related to cybersecurity?
– Is your most sensitive data protected by the laws of physics?

At QuintessenceLabs, our software engineers fuse science with technology to build enterprise-grade, hardened appliances for the most demanding cybersecurity applications. And even if you’re a bit hazy on Heisenberg’s uncertainty principle, we need talented software engineers to help build a diverse range of cutting-edge technologies. And we do mean cutting edge.

If you appreciate the elegance in leveraging the unbreakable laws of physics, have a track record of delivering innovative yet stable designs, and are driven to provide quality outcomes, you share our values. We offer a friendly but focused environment, working side by side with smart people on challenging problems. Many of our employees have PhDs — though that’s certainly not a requirement — while others have deep industry experience, or both.

Our recruiting practices have resulted in a strong, harmonious team with diverse skills and experiences, so we aren’t hung up on any particular technologies when hiring. We primarily develop using C and PHP on Linux, so familiarity with the demands of working at a low level would be advantageous. But if you’re an expert in other languages with a capacity to learn new skills quickly, you might wish to consider a career at QLabs. We’re always looking for smart people who get things done.


– A demonstrable passion for software engineering is a must
– Being able to work collaboratively in a team environment is how we roll
– A Bachelor’s degree in Computer Science, Software Engineering, Information Services or equivalent experience is where we set the bar
– Experience with C or C++ on Linux is optimal, but a deep understanding of other languages and platforms helps
-Understanding client-server programming, operating system calls, and good programming practices goes without saying
– Familiarity with PostgreSQL, PHP, JavaScript and Python ticks more boxes
– Lastly, while knowledge of crypto concepts isn’t essential, it is a plus
