7AI is the foundational AI security company. Founded in 2024 by Cybereason co-founders Lior Div and Yonatan Striem-Amit, we came out of stealth in February 2025 to take on the non-human work of the SOC. Our platform pairs a federated SIEM with AI agents that detect, investigate, respond, and hunt, plus dedicated threat hunting and threat intelligence, with humans on the loop.
Backed by $166 million in total funding from investors including Index Ventures and Blackstone, we're building the AI foundation for security operations in the agentic era, and we're still early. That's the appeal: you'll join at a pivotal stage where your work shapes what 7AI becomes, alongside security veterans who've built this before. Our culture runs on respect, collaboration, and a shared bar for excellence, all pointed at one goal, delivering real outcomes for the customers who trust us to defend them.
As 7AI takes on more of the SOC's non-human work, the systems underneath have to scale with it, or the platform becomes the bottleneck instead of the fix. You'll join our core R&D team as a Senior Software Architect, helping define and evolve the technical foundation of our platform as we scale. You'll work across engineering, product, and AI teams, designing systems that are reliable, scalable, and ready to use new AI tooling. As a senior individual contributor, you'll shape architecture, guide key technical decisions, and turn complex ideas into production-ready systems.
Own and evolve system architecture across the platform, keeping it scalable, reliable, and maintainable.
Partner with engineering and product teams to design systems that balance fast delivery with long-term flexibility.
Lead technical decisions and weigh trade-offs across performance, cost, and complexity.
Turn ambiguous business or product needs into clear technical approaches and system designs.
Spot architectural gaps, technical debt, and scaling bottlenecks, and fix them before they become blockers.
Mentor engineers and act as a technical thought partner across teams.
Evaluate and apply AI tools, frameworks, and workflows to improve the product and speed up internal development.
Track advances in AI development and help the team adopt the ones worth adopting.
Help build a culture of curiosity and experimentation with AI across the organization.
20+ years of software engineering experience, with deep expertise in system design and architecture.
A track record of designing and evolving distributed, scalable systems.
Broad AWS cloud architecture experience, including designing and building complex data plane and control plane systems.
Comfortable going deep technically while influencing broadly across teams.
Experience working cross-functionally with product, engineering, and business stakeholders.
Strong communication skills, with the ability to explain complex systems clearly.
Experience with data pipelines, highly scalable systems, and cloud native architectures and services.
Experience in cybersecurity.
