Senior Backend Engineer

About 7AI

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.

Overview

Every AI agent 7AI ships depends on the data pipeline underneath it: get that wrong and the agent's calls get worse, at the customer's expense. We're looking for a Senior Backend Engineer to join our core engineering team. You'll design and build the data pipelines and processing platform at the heart of our AI-native cloud platform, and you'll help choose the technologies and architecture behind it. The work centers on complex cybersecurity problems, and it needs to scale and hold up in production.

What You'll Do

• Design, implement, and maintain the core data pipelines and processing platform for our AI-native cloud platform.
• Build scalable, reliable solutions for complex cybersecurity use cases.
• Choose and implement the technologies and architectures the platform needs.
• Ensure the scalability, reliability, and performance of our cloud-based services.

What We're Looking For

• 5+ years of backend development experience.
• Hands-on experience designing and building cloud systems.
• Strong software development skills and a bias toward shipping fast.
