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.\nBacked 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.\nOverview\nAn AI-native cybersecurity platform is only as trustworthy as the systems it runs on. Get the foundation wrong and every AI agent built on top inherits that risk. As a Principal Software Engineer, you'll help define the technical foundation of our AI-native cybersecurity platform. You'll lead system design, drive complex technical initiatives from concept to production, and mentor engineers across the organization. You'll partner closely with engineering, product, design, AI, and security teams to turn hard, ambiguous problems into solid technical solutions. This is a 0→1 role for someone who wants real influence over both the technology and the engineering culture.\nWhat You'll Do\nLead design of scalable backend systems for our AI-native cybersecurity platform.\n\nDrive complex technical initiatives from 0→1, including system design, technical strategy, implementation, and operationalization.\n\nPartner with product, AI, security, and platform teams to turn ambiguous business and customer problems into solid technical solutions.\n\nLead design discussions and provide technical leadership across multiple engineering domains and initiatives.\n\nIdentify and address technical risks, scalability bottlenecks, and operational challenges before they affect the business.\n\nImprove system observability, reliability, testing, deployment workflows, and operational excellence across engineering.\n\nHelp shape engineering culture by promoting high standards for execution, craftsmanship, collaboration, and ownership.\n\nMentor engineers through technical guidance, design reviews, and hands-on collaboration.\n\nWork effectively in a fast-changing environment where priorities and technical challenges shift quickly.\n\nWhat We're Looking For\n15+ years of professional software engineering experience building and operating production-grade distributed systems.\n\nProven experience leading the design and delivery of large-scale, highly available cloud-native systems.\n\nStrong system design expertise, including distributed systems, APIs, event-driven architectures, data-intensive applications, and infrastructure scalability.\n\nExperience leading complex technical projects with significant ambiguity and cross-functional coordination.\n\nStrong proficiency in one or more backend languages such as Rust, Python, TypeScript, or Go.\n\nTrack record building systems on AWS, GCP, or Azure.\n\nStrong communication skills, with the ability to explain complex technical concepts to both technical and non-technical audiences.\n\nComfortable and curious working with AI-assisted development tools such as Claude Code, Codex, or Cursor.\n\nNice to Have\nExperience building AI-native products or integrating LLM/agent-based systems into production environments.\n\nBackground in cybersecurity, security operations, or high-sensitivity infrastructure environments.\n\nExperience designing multi-tenant SaaS platforms at scale.\n\nFamiliarity with real-time data pipelines, streaming systems, and large-scale telemetry processing.\n\nExperience working in high-growth startup environments.\n\nTrack record building and scaling engineering teams, processes, and technical culture.","description_format":"text","description_chars":4058,"description_truncated":false,"requirements":{"experience_years_min":15,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Information Security","Security Operations","AI Agents","Cybersecurity AI"],"lifecycle":[{"event":"open","at":"2026-05-06T16:55:27Z"}],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.241,"p_room":0.28,"age_days":144,"expected_fill_days":40,"reasons":["conf:0","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-09-28T05:45:00Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":true},"html_url":"https://alion.io/job/seven-ai-principal-software-engineer-cloud","json_url":"https://alion.io/job/seven-ai-principal-software-engineer-cloud.json","meta":{"generated_at":"2026-09-29T02:23:41Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2095,"day_limit":5000,"remaining_today":2905,"minute_limit":60,"resets_at":"2026-09-30T00:00:00Z"}}}
