Ensure these principles are understood, embraced, and consistently applied across the team - through documentation, code review, pairing, and example.
Drive the evolution of the connector/integration framework shared across OpenCTI, OpenAEV, and OpenGRC - making it easier, faster, and more reliable to build high-quality integrations.
Make key technical decisions on integration architecture: data flow design, error handling, retry strategies, observability, performance, and security.
Define and enforce contribution guidelines, code standards, and documentation practices that make it easy for community members to develop their own connectors.
8+ years of experience in software engineering, with a track record of technical leadership on complex, production-grade systems.

• Deep Python expertise - Python is the core language of the XTM Integration ecosystem. Solid understanding of integration and data pipeline patterns : event-driven architectures, ETL/ELT, API design (REST, GraphQL, webhooks), authentication flows, rate limiting, and error recovery.
• Proven ability to define and carry technical standards - you've been the person who raises the bar on a team, not just follows it.
• Strong open-source mindset : you understand what it means to build software for an external community, not just internal users. Comfortable working in a remote-first, async culture ; clear communicator in English.
• Bonus: Experience with cybersecurity tooling (SIEM, EDR, SOAR, threat intelligence platforms); OpenCTI connectors - import, export, enrichment, and stream connectors that bring external threat data in and push intelligence out to security tools (SIEM, EDR, SOAR, ticketing, and more).

OpenAEV collectors and injectors - integrations that feed adversarial exposure scenarios with real-world data and drive automated attack simulation across target systems.
OpenGRC connectors - integrations that connect governance, risk, and compliance workflows to external data sources and security tools.
The team owns the problems that no single product team can solve alone: shared architecture, inter-product communication standards, common UI components, CI/CD infrastructure, test quality, developer experience, and AI-assisted development practices.
They bring deep expertise, evaluate new approaches before rolling them out at scale, and help 60+ engineers build better software, faster.
We're a fast-growing, global, and fully remote company building open-source cybersecurity solutions, increasingly powered by AI, to help defense teams anticipate threats and act faster.
