The Position

We are excited to welcome a motivated Associate Threat Detection Analyst to our expanding Technology Office team in Ho Chi Minh City.

In this role, you will contribute to the development and enhancement of high-performance software solutions that power our cutting-edge cybersecurity products across on-premise, cloud, and hybrid deployments. You will leverage our advanced AI-driven platform, which integrates machine learning models, behavioral analytics, anomaly detection, and generative AI capabilities to accelerate threat identification, automate complex malware analysis, predict emerging attack patterns, and build more resilient defenses against sophisticated threats including AI-generated and adaptive malware.

Working as part of a collaborative global team (with members in Vietnam, Spain, Romania, UK, US, Georgia, and Hungary), you will gain hands-on experience collaborating closely with senior engineers—both locally and remotely—in a supportive, international environment that prioritizes innovation, continuous learning, and the effective application of AI to solve real-world cybersecurity challenges.

What You Will Be Doing

• Malware Analysis & Reverse Engineering – the foundation of everything we do.

• AI-Enhanced Malware Analysis – Leverage AI-powered tools and models to accelerate threat detection workflows, including automated behavioral classification, anomaly scoring, similarity matching for malware families, and generative AI for simulating attack variants or generating high-quality detection rules.

• Sandbox Capability Development – implement new extraction features (filetype-specific parsers, config extractors, etc.) to enrich behavioral detection artifacts.

• Threat Indicator Development – identify and flag structural and behavioral patterns of interest.

• YARA Rule Vetting & Development – validate community rules and create tailored detection signatures.

• Detection Accuracy – hunt for misleading sandbox reports and ensure proper sample classification.

• Threat Detection Service – review, triage, and resolve detection inaccuracies reported by customers.

• Technical Initiatives – drive innovation to advance OPSWAT’s threat detection capabilities and maximize sandbox effectiveness.

• Knowledge Sharing – promote collaboration within the team and across OPSWAT.

• Automation – develop scripts and tools to streamline analysis workflows.

• Research – stay on top of evolving malware trends, TTPs, and sandbox detection techniques.
