Software Development Engineer in Test - MD Tri
OPSWAT, a global leader in IT, OT, and ICS critical infrastructure cybersecurity, delivers an end-to-end platform that gives public and private sector organizations and enterprises the critical advantage needed to protect their complex networks, secure their devices, and ensure compliance. Over the last 20 years our commitment to innovative technology has earned the trust of more than 1,700 organizations, governments, and institutions globally, solidifying our role in protecting the world’s critical infrastructure and securing our way of life.
The Position
We are building an AI-powered, autonomous vulnerability management platform that goes beyond traditional scanning by using advanced AI agents to predict, prioritize, and remediate threats before they can be exploited.
Our mission is to shift security from reactive to predictive, delivering true end-to-end visibility and replacing manual processes with intelligent, agent-driven workflows.
In this role, you will own the automation testing strategy and pipelines, ensuring data accuracy, system reliability, API correctness, and performance at scale. You’ll work closely with AI, software, and security engineers to enable fast, high-quality releases for a platform handling large-scale, security-sensitive data.
Join us to shape the future of vulnerability management and cybersecurity automation!
What You Will Be Doing
• Design and implement end-to-end automation testing frameworks covering API, functional, integration, and performance testing.
• Build automated test pipelines for REST APIs, GraphQL, webhook integrations, and AI Agent Workflows.
• Develop data validation and consistency checks to ensure accuracy of vulnerability intelligence and enrichment data.
• Implement performance testing for large-scale vulnerability ingestion and processing pipelines.
• Integrate automated tests into CI/CD pipelines to enable fast, reliable product releases with high confidence.
• Collaborate closely with software engineers, AI engineers, and security engineers to define test strategies early in the development of lifecycles.
• Create test environments, mocks, and test data strategies for complex distributed systems.
• Continuously improve test reliability, execution speed, and observability.
What We Need From You
• 2+ years of experience in software development engineering in testing.
• Strong experience testing APIs (REST, GraphQL, webhooks) using automation frameworks.
• Proficiency in Python (or similar scripting language) for test automation and tooling.
• Experience with testing frameworks such as Playwright, Cypress, JMeter or equivalent.
• Strong understanding of test strategies for distributed systems and data-intensive platforms.
• Experience with using AI to build framework and create datasets to test against complex systems.
It Would Be Nice If You Had
• Experience testing AI/ML or data-driven systems, including non-deterministic outputs.
• Cybersecurity background: understanding of vulnerability, security tools and workflows.
• Performance and scalability testing for high-throughput data pipelines.
• Microservices architecture and containerization (Docker, Kubernetes).
• Familiarity with message queues (Kafka or similar) and event-driven architecture.
• Cloud-native testing experience on AWS or similar platforms.
• Experience defining quality gates and release criteria for fast-moving engineering teams.
