You will own the client side of our applications, from component architecture and state to performance and testing, and work closely with our backend (Python) and design teams. We are open to the framework: we want real production depth in Angular or React. What matters is that you can reason from first principles about components, state, rendering, and performance, rather than following one framework's recipes. Our products use both, so you should be willing to work in the one you know less well. This is a builder's role. You should be comfortable writing clean, typed TypeScript, reasoning about how and when your UI re-renders, and shipping complex interfaces that hold up in production.\nResponsibilities:\nDesign, build, and maintain front-end applications in Angular or React components, state, routing, and data flow.\nWrite clean, reactive code using modern patterns like RxJS and Angular Signals, or React hooks and a data-fetching layer such as React Query.\nOwn front-end performance: rendering and change detection, bundle size, and load time.\nBuild complex, data-heavy UIs and forms with robust validation.\nIntegrate and consume REST APIs, handling loading, error, and edge states cleanly.\nWrite meaningful front-end unit tests for the components you ship.\nUphold UI/UX consistency and mentor less experienced developers.\nRequirements:\nThis is a senior front-end role; we expect real depth in at least one major framework, not surface familiarity with several.\n5+ years of relevant, hands-on front-end development experience.\nAngular or React genuine production experience with components, state management, forms, routing, and data flow. Depth in one is required; experience in both is a plus.\nStrong TypeScript and solid HTML/CSS with responsive, cross-browser layouts.\nAbility to reason about and fix rendering performance, change detection in Angular, or re-render and memoization behavior in React.\nReactive and asynchronous data flow: RxJS streams, or hooks, effects, and async state in React.\nFront-end testing (Jasmine/Karma, Jest, Vitest, or React Testing Library).\nComfort consuming REST APIs and working with Git.\nWillingness to work in the other framework: if you are an Angular developer, we expect you to pick up React and the other way round.\nNice to Have:\nProduction experience in both Angular and React.\nAngular Signals, or modern React patterns (server components, suspense).\nState management at scale: NgRx, Redux, Zustand, or similar.\nNext.js, or Angular SSR/hydration.\nA strong eye for design and accessibility (a11y).\nSome familiarity with the backend (Python / REST / AWS).","description_format":"text","description_chars":2725,"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":[],"lifecycle":[{"event":"open","at":"2026-10-09T05:14:49Z"}],"visa":[],"liveness":{"score":85,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.851,"p_room":1,"age_days":4,"expected_fill_days":22,"reasons":["seen:4","win:early"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/kots-sr-frontend-developer","json_url":"https://alion.io/job/kots-sr-frontend-developer.json","meta":{"generated_at":"2026-10-13T09:50:13Z","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":14867,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":4373326},"rest":"https://alion.io/mcp/rest/get_company?id=4373326"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkots-sr-frontend-developer"},{"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%2Fkots-sr-frontend-developer"},{"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%2Fkots-sr-frontend-developer"},{"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/kots-sr-frontend-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkots-sr-frontend-developer"}]}
