About Proofpoint

We provide the most effective cybersecurity and compliance solutions to protect people on every channel including email, the web, the cloud, and social media.

Job Description

It's fun to work in a company where people truly BELIEVE in what they're doing!

We're committed to bringing passion and customer focus to the business.

Job Description 

At Proofpoint you get to feel like a superhero, knowing you are obstructing and thwarting organized criminal organizations from stealing billions of dollars from legitimate businesses.  With so much money to be made, the criminals are constantly searching for new techniques to slip their malware or socially engineered lures past existing defenses. Proofpoint protects many enterprise companies worldwide, sees a large volume of corporate email, and is therefore in a unique position to identify emerging threats. 

We are singularly devoted to helping our customers protect what matters most. That’s why we’re a leader in next-generation cybersecurity—and why more than half of the Fortune 100 trust us as a security partner.  

Proofpoint is looking for a Principal Engineer to drive architecture and design of scalable cloud services to support Proofpoint’s rapidly growing business. You will serve as a technical leader and mentor your fellow engineering members and promote best practices such as design reviews, code reviews, secure coding and performance tuning.  You'll be expected to roll up your sleeves and sling production code as well as proofs of concept.  

Come work at a growing business that builds scalable, resilient and adaptive systems to process customer-critical data against active adversaries. 

Our ideal candidate has demonstrated thought leadership and hands-on expertise while implementing massively scalable platforms leveraging cloud technologies and distributed systems.  Significant contributions to open-source initiatives and reputation as an industry expert in your field is a big plus.  You have demonstrated that you value project impact over project completion, personal ownership over observation, and measurement over opinion.  

Above all else, you'll have a constant desire to make things better, learn more and help others do the same. 

So, if you're a visionary/inventor type with the confidence that you have the talent and motivation to help us solve the data security problems of the world’s most targeted companies we'd love to hear from you. 



  • What you bring to the team
    • Establish a clear technical and architectural vision for key projects.
    • Demonstrate a strong passion for continuous learning and a driving intellectual curiosity by bringing fresh perspectives on leading industry standards, best practices, emerging trends, directions, etc.
    • Promote the benefits of experimentation and the application of cutting-edge technology. In addition, advance the software paradigms by providing beneficial recommendations on new and emerging technologies, prototypes, patent proposals, and process improvements.
    • Research available technologies and help us make informed build vs. buy decisions. 
    • Build proof of concepts for new ideas and later bring those to production level code.
    • Closely work with our operations team and constantly drive improvements to our operational environment.
    • Mentor other software developers and provide technical leadership.
    • Strong experience working with large scale distributed systems, scalability, high-performance computing with a proven ability to speak authoritatively about architectural, design, and implementation details
    • An irrepressible excitement for the cloud, big data, and the possibilities it affords for new forms of services and applications
    • Working knowledge of the entire stack of modern cloud technologies such as data processing pipelines, streaming engines, continuous delivery, and verification.
    • Degree in Computer Science or equivalent
