You’ll secure open source ecosystems, strengthen threat detection across multiple programming languages, and conduct research that helps protect developers and organizations worldwide.

• Design and build automated scripts and tools to streamline malware analysis, enhancing our data collection, threat analysis, and threat hunting workflows.

• Partner with our engineering team to integrate your research into our core product, turning manual insights into scalable, real-time protection.

• Leverage expertise in open source software ecosystems to enhance security across package registries, browser extensions (Chrome/VS Code), and proactively monitor GitHub/GitLab for emerging malicious campaigns.

• Track APT (Advanced Persistent Threat) adversaries, characterizing various TTPs (Tactics, Techniques, and Procedures), capabilities, infrastructure, and campaigns.

What You'll Bring

Required

• 3+ years of work experience and a master’s degree in computer science, engineering, or a related field (or equivalent experience).

• Technical experience across several areas of security operations, including investigations, incident response and management, digital forensics, malware analysis, reverse engineering, threat intelligence, threat hunting, and detection engineering.

• Excellent communication skills and the ability to assess the relevance and impact of threats.

• Experience building tools for automation, data collection, and threat hunting.

• Passion for open source and code.

Preferred

• Familiarity with TypeScript/JavaScript and/or other programming languages and ecosystems protected by the company.

• Experience leveraging LLMs or AI-based tools for threat detection.
