About this AI Native Senior Software Engineer role at OPSWAT
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
MetaDefender Endpoint is our flagship cross-platform endpoint security platform, trusted by governments, critical infrastructure operators, and global enterprises to secure millions of devices across Windows, macOS, and Linux. Our mission is to build endpoint protection that is fast, resilient, and designed for the increasingly sophisticated cyber threats of today and tomorrow.
As we continue to invest in AI across our engineering organization, we're looking for engineers who not only write great code but also know how to leverage AI to maximize their productivity and impact. We believe the best engineers combine deep technical fundamentals with sound engineering judgment, using AI assistants such as GitHub Copilot, Cursor, and Claude Code to accelerate development while maintaining high standards for quality, security, and maintainability.
If you're passionate about modern C++, enjoy solving complex systems and security challenges, and are excited about shaping how AI transforms software engineering, we'd love to hear from you. Join us to build products that protect organizations around the world while helping define what AI-native engineering looks like at OPSWAT.
What You Will be Doing
- Design, build, and ship features across the MetaDefender Endpoint C++/Qt codebase (Windows primary; macOS and Linux supported).
- Use GitHub Copilot, and Claude Code daily to accelerate coding, testing, and documentation, while evaluating AI-generated code for correctness, security, and maintainability before it ships.
- Author and maintain AI context files for the modules you own, so agents produce consistent, on-pattern code across the team.
- Review code with a security-first lens, for both human- and AI-generated changes.
- Mentor teammates on effective AI tool usage and endpoint / security C++ best practices.
What We Need from You
- 3+ years of professional C++ development experience.
- Strong fundamentals: memory management, concurrency, RAII, design patterns, secure coding.
- Experience shipping cross-platform desktop or endpoint software on Windows (macOS / Linux a plus).
- Debugging skills with WinDbg, lldb, or gdb.
- Unit testing experience with GoogleTest, Catch2, or equivalent.
- 1+ years of professional experience using AI-assisted development tools (GitHub Copilot, Cursor, or Claude Code) to ship production code, with judgment to evaluate AI-generated output before committing.
It Would Be Nice If You Had
- Prior experience with endpoint security, AV / EDR, device control, or Windows internals.
- Experience authoring AI context files (CLAUDE.md, .github/copilot-instructions.md, .cursorrules) that encode architecture decisions and forbidden patterns.
- Familiarity with running AI agents in CI/CD pipelines (auto-fix lint, generate tests, triage failures).
- Secondary languages: Python or Go.
- Experience shipping Qt / QML applications across Windows, macOS, and Linux.
- Open-source contributions or personal projects that show how you work with AI tools.
