Staff Security Research Engineer
As a Security Research Engineer on Proofpoint’s Threat Research team, you’ll be part of an amazing, collaborative, industry-leading team focused on tracking threat actors, malware, phishing, and TTPs and responding to the quickly changing threat landscape with innovative software that detects and prevents threats from reaching Proofpoint customers.
Your day-to-day

Design and develop software using a variety of languages, primarily Python, with little external guidance, while providing technical leadership to guide other software engineers on the team
Modify existing web-based UI for internal tools to maintain and extend the sandbox submission and report UI for Proofpoint threat researchers to use
Write C or C++ for low level interactions with the OS as needed
Develop and maintain web browser interaction capabilities using Chrome Web Driver
Analyze and reverse engineer JavaScript that fingerprints web browser artifacts to identify sandbox browsers or instrumentation, and innovate solutions to defeat those checks
Familiarity with analyzing web front-end and the Document Object Model (DOM)
Develop and maintain software for processing network traffic, including TLS decryption and processing PCAP files
Work closely with threat analysts and detection engineers who research threat actors and write detection rules which run on the systems you develop
As needed, create new detection languages and systems that allow threat researchers to develop detection rules
Add features to existing threat detection languages to allow greater flexibility by threat researchers to automate interactions with websites and detect threat patterns
Make use of AI Large Language Models as appropriate to enhance threat detection pipelines, produce samples to test evasion countermeasures, and decide when applying AI is beneficial
Design and develop automation pipelines to turn manual tasks into automated scripts
Stay abreast of a constantly evolving threat landscape
Understand the latest tactics, techniques, and procedures used by threat actors to bypass detection environments, especially URL sandbox fingerprinting, detection, and evasion techniques
Provide expert assistance and support to threat researchers and analysts as they analyze phishing websites, threat detection evasion techniques, and security research or red team demonstrations of new evasion techniques
Reverse engineering malware executable files for Windows as needed to support sandbox countermeasure development (note primary malware reverse engineering responsibilities rest on other roles and are not expected regularly for this role)
Apply critical thinking to identify efficient and effective ways to mitigate threats and evasions
Work effectively as part of a remote team using chat, video chat and conference calls
Collaborate with other engineering teams, defining requirements for continuous improvement of critical detection capabilities
