While these tools allow developers to build faster than ever, they also introduce a completely new frontier of security challenges that exist directly on the engineer's machine.\nBackslash is building the security layer for this new reality. We provide the essential guardrails and visibility needed to secure AI-driven workflows. By actively protecting developer computers and monitoring IDE-based AI interactions, we ensure the future of coding is as secure as it is fast.\nThe Role\nAs an Engineer, you will be responsible for the infrastructure that connects our local protection agents to our high-scale cloud backend.\nArchitect Distributed Systems: Design and evolve a robust microservices architecture capable of handling high-throughput telemetry and security events from thousands of distributed developer machines.\nMaster Endpoint Deployment: Own the delivery and lifecycle of our protection agent, ensuring it deploys seamlessly to engineer laptops and runs with a zero-friction resource footprint.\nScale Data Infrastructure: Build the backend pipelines and storage solutions that ingest, process, and provide visibility into real-time security data from IDEs and local AI tools.\nDeliver Full-Stack Features: Take end-to-end ownership of features, contributing to the user interface to ensure backend data and endpoint health are presented clearly to our users.\nDrive Technical Excellence: Set the standard for stability through automated quality gates and a commitment to building low-latency, resilient software that developers can trust on their machines.\nRequirements\nWe’re looking for a backend specialist who thinks in systems and data flow but can navigate the full stack when the feature requires it.\nEngineering Depth: 5+ years of software engineering experience, with a track record of shipping complex backend systems or distributed architectures.\nMicro-services Mastery: Hands-on experience designing and maintaining microservices in production, including service discovery, inter-service communication, and high-scale data ingestion.\nBackend Expertise: Highly proficient in server-side development using modern ecosystems (like NestJS, Adonis etc.) and a strong command of TypeScript/Node.js.\nFull-Stack Capability: Practical experience with modern frontend frameworks (like React or Vue). You are comfortable building UI components to visualize the telemetry and insights of backend processes.\nCloud Native: Strong experience with containerization (Docker, Kubernetes) and major cloud platforms (AWS, GCP, or Azure).\nStartup DNA: You thrive on ownership. You want to solve problems, not just execute tasks.\nBonus points for\nEndpoint & Systems: Familiarity with building software that runs locally on macOS, Linux, or Windows (background agents, daemons, or system services).\nCybersecurity Interest: Experience in EDR/XDR, endpoint protection, or a deep interest in securing developer workflows.\nData Scale: Experience designing and implementing complex algorithms or high-performance data pipelines.","description_format":"text","description_chars":3244,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","AI Agents","Cybersecurity AI"],"lifecycle":[{"event":"open","at":"2026-10-14T06:45:20Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.252,"p_room":0.28,"age_days":232,"expected_fill_days":31,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-14T11:44:08Z"},"pay":null,"html_url":"https://alion.io/job/backslash-security-senior-full-stack-engineer","json_url":"https://alion.io/job/backslash-security-senior-full-stack-engineer.json","meta":{"generated_at":"2026-10-14T11:44:08Z","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":14049,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":177899},"rest":"https://alion.io/mcp/rest/get_company?id=177899"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbackslash-security-senior-full-stack-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%2Fbackslash-security-senior-full-stack-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%2Fbackslash-security-senior-full-stack-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/backslash-security-senior-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbackslash-security-senior-full-stack-engineer"}]}
