Proofpoint

A cybersecurity provider specializing in email protection, advanced threat defense, and information security solutions for organizations.

Senior Threat Researcher

In today's cyber threat landscape, protection starts with people. At Proofpoint, that simple truth fuels our passion for protecting users, the data they create, and the systems they rely on from a uniquely people-centric perspective.

And we're just as passionate about finding the right people to help us in that mission. When you join Proofpoint, you're helping to:

  • Build and enhance our proven security platform
  • Blend innovation and speed in a constantly evolving cloud environment
  • Analyze new threats and offer deep insight through data-driven intel
  • Collaborate with customers to help solve their toughest security challenges

We are singularly devoted to helping our customers protect their greatest assets and biggest security risk: their people. 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.

As a Senior Threat Researcher, you'll investigate financially motivated threat actors across Proofpoint's technology stack. You'll turn threat data into actionable intelligence and help shape detection strategies that protect our customers. This role blends traditional CTI Analyst function with the deep technical expertise needed to analyze and explain granular details of multi-stage attack chains associated with complex activity sets.

Your day to day includes:

  • Hunt for eCrime activity in Proofpoint's proprietary telemetry and external sources
  • Analyze a variety of threat types including phishing, malware, BEC, cloud, and malicious infrastructure.
  • Cluster, persistently track, and attribute malicious activity sets.
  • Deliver intelligence to internal teams and customers through clear, compelling communication.
  • Collaborate with detection engineers to maintain high efficacy for our product suite.
  • Contribute to public and private threat intelligence efforts (with additional opportunity to present findings at events, conferences, etc.)
  • Use AI-based tools to accelerate analysis, enrich findings, and automate repetitive tasks.

What you bring to the team includes:

  • Proven experience tracking financially motivated threat actors and their TTPs.
  • Strong grasp of threat intelligence principles, including IOC analysis and actor attribution.
  • Technical skills involving infrastructure tracking, static and dynamic malware analysis, reverse engineering, and scripting for automation.
  • Comfort working across diverse teams and communicating with customers and stakeholders.
  • Experience working with large datasets to uncover meaningful insights.
  • Enthusiasm for developing custom tooling and integrating AI into your workflows to enhance research and detection.

Bonus skills include:

  • Experience with email delivery and threat analysis (SMTP, MIME, headers).
  • Familiarity with Suricata, Snort, YARA, Clam AV, Sigma, or other signature languages.
  • Public-facing research contributions (blogs, talks, papers). Remote work experience in a security-focused organization. The ability to speak multiple languages.

Protecting people is at the heart of our award-winning lineup of cybersecurity solutions, and the people who work here are the key to our success. We're a customer-focused and driven-to-win organization with leading-edge products—and many exciting reasons to join our team. We believe in hiring the best the brightest and cultivating a culture of collaboration and appreciation. We are a diverse, multinational company with opportunities in all functions, and leaders that welcome candidates from all walks of life. Apply today and explore your future #LifeAtPFPT.
