We believe security should go beyond detecting attacks to reduce what attackers can do in the first place.\nFounded by the team behind Medigate, which was acquired by Claroty, we’re a small team with ambitious goals. We stay close to our customers and trust the people closest to the work to make decisions and own the outcome.\nSome of our hardest problems are still ahead. If you want to tackle fundamental challenges with people who care deeply about their work and each other, we’d love to build with you.\nThe role\nWe are looking for a Frontend Engineer to join our team and own the user-facing experience of our cloud security platform. You'll build a fast, intuitive, and data-dense product that lets security teams understand and act on complex cloud access data at a glance.\nWhat you’ll do\nDesign and build a modern, responsive web application using React and TypeScript\n\nTranslate complex security and cloud data into clear, actionable, and intuitive UI/UX\n\nBuild reusable component libraries and design systems that scale across the product\n\nWork closely with Product and Design to turn concepts into polished, production-ready features\n\nOptimize application performance, especially around large, data-heavy views (graphs, tables, dashboards)\n\nCollaborate with backend engineers to define clean, efficient APIs\n\nLeverage AI tools as part of your daily workflow - we build with AI, not just for AI\n\nImprove our codebase, tooling, and engineering practices as we grow\n\nWhat you’ll bring\nAt least 5 years of hands-on frontend development experience\n\nStrong proficiency in React and TypeScript, with deep understanding of modern frontend architecture\n\nExperience building complex, data-heavy UIs (dashboards, visualizations, tables at scale)\n\nStrong sense of UI/UX and attention to detail\n\nFamiliarity with state management, testing, and performance optimization in large frontend codebases\n\nExperience working closely with backend and design teams\n\nStrong sense of ownership, clear communication, and ability to move fast without cutting corners\n\nWorking at Act\nLearn from real problems. We learn from our customers, each other, and our mistakes, and use what we learn to improve what we build.\n\nBuild with AI. We use AI tools in our daily work, build intelligent automation into our product, and help customers secure their AI workloads.\n\nSet a high bar, together. We pursue ambitious goals and hold ourselves to high standards. We also believe great work happens when people enjoy working together.\n\nShare in what we build. We offer competitive compensation and meaningful equity, with the opportunity to help shape an early-stage company.","description_format":"text","description_chars":2957,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud Security","E-learning","Venues"],"lifecycle":[{"event":"open","at":"2026-09-26T08:48:47Z"}],"liveness":{"score":37,"band":"fade","label":"Fading","p_open":1,"p_active":0.49,"p_room":0.75,"age_days":22,"expected_fill_days":30,"reasons":["conf:6","win:late"],"computed_at":"2026-09-29T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/act-security-frontend-engineer","json_url":"https://alion.io/job/act-security-frontend-engineer.json","meta":{"generated_at":"2026-09-30T02:52:59Z","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":2119,"day_limit":5000,"remaining_today":2881,"minute_limit":60,"resets_at":"2026-10-01T00:00:00Z"}}}
