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\nEvery 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.\nWhat You'll Do\nDesign, implement, and maintain the core data pipelines and processing platform for our AI-native cloud platform.\n\nBuild scalable, reliable solutions for complex cybersecurity use cases.\n\nChoose and implement the technologies and architectures the platform needs.\n\nEnsure the scalability, reliability, and performance of our cloud-based services.\n\nWhat We're Looking For\n5+ years of backend development experience.\n\nHands-on experience designing and building cloud systems.\n\nStrong software development skills and a bias toward shipping fast.\n\nBachelor's degree or equivalent in a relevant field.\n\nStrong problem-solving and communication skills.","description_format":"text","description_chars":2079,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Security Operations","AI Agents","Cybersecurity AI"],"lifecycle":[{"event":"open","at":"2026-05-06T01:06:42Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.478,"p_room":0.28,"age_days":181,"expected_fill_days":46,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-11-03T05:54:40Z"},"pay":{"stated_usd_annual":220000,"is_top_pay":true},"html_url":"https://alion.io/job/7ai-senior-backend-engineer","json_url":"https://alion.io/job/7ai-senior-backend-engineer.json","meta":{"generated_at":"2026-11-03T07:57:37Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":11342,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":11741},"rest":"https://alion.io/mcp/rest/get_company?id=11741"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2F7ai-senior-backend-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2F7ai-senior-backend-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2F7ai-senior-backend-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/7ai-senior-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2F7ai-senior-backend-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":91615}},{"tool":"search_jobs","arguments":{"company":"7ai.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":91615},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
