To do this, we’re building the world's first AI hardware engineer. Founded in 2019, our platform enables anyone to go from idea to manufacturable board using nothing more than a natural language prompt. This democratizes a process that has historically required years of specialized expertise.\nWe're going after a $15B+ electronic design automation market, backed by 8VC, Bain Capital Ventures, Liquid 2 Ventures, Outsiders Fund, Figma board member John Lilly, and GitHub founder Tom Preston-Werner. In February 2026, we closed a total of $37M in funding to accelerate that mission.\nWhat happens when we unlock the ability for anyone to make hardware? We fundamentally reshape the world. That's our mission, and we're just getting started.\nThe Role\nWe’re hiring a Product Engineer, Frontend to shape the core web experience of Flux.\nYou will work across our browser-based editor, collaboration systems, and AI-powered workflows. This is a high-ownership product engineering role focused on building and evolving complex, interactive interfaces used for real engineering work.\nYou’ll spend most of your time in React and TypeScript, partnering closely with design and ECAD engineers to keep a sophisticated, real-time application fast, intuitive, and maintainable.\nWe are open to mid-level through senior candidates. Level, scope, and compensation will align to demonstrated experience, ownership, and the complexity of problems you can independently drive.\nWhat You’ll Do\nBuild and evolve core user-facing features in the Flux web app using React and TypeScript.\n\nPartner with design to refine flows and interactions from early concepts through production.\n\nMaintain predictable and scalable UI state and data flows within a collaborative, multi-pane editor environment.\n\nImprove responsiveness and perceived performance as projects increase in size and complexity.\n\nIntegrate frontend systems with APIs and backend services; collaborate on backend changes when needed.\n\nMaintain and evolve shared component libraries and design system primitives.\n\nAdd and maintain instrumentation for owned features (usage metrics, error logging, UX dashboards).\n\nParticipate in code reviews, design discussions, and lightweight documentation.\n\nMentor other engineers on frontend best practices where appropriate.\n\nWhat You’ll Bring\nStrong command of modern React and TypeScript in sizable production codebases.\n\nExperience shipping and iterating on complex, interactive web applications (e.g., design tools, visual editors, multi-pane interfaces).\n\nExperience building responsive UIs on top of asynchronous or computation-heavy backend systems.\n\nStrong product judgment and experience collaborating closely with design and product.\n\nExperience with browser performance profiling and debugging.\n\nComfortable working across the stack to integrate APIs and make small backend changes.\n\nExperience in startup or high-ownership environments.\n\nBased in the San Francisco Bay Area or willing to relocate.\n\nPreferred Qualifications\nExperience building distributed, collaborative, real-time applications.\n\nExperience with complex editor interfaces, CAD, developer tools, or design tools.\n\nFamiliarity with state management patterns in large React applications (Redux or equivalent).\n\nExperience with WebWorkers, WebAssembly, or background computation in the browser.\n\nExperience integrating AI-powered features into user-facing products.\n\nExperience building high-performance frontends handling large data models.\n\nOpen source contributions in frontend or developer tooling.\n\nProfile\nImpact-oriented - You care about real user value, not just shipped code.\n\nComfortable with ambiguity - You thrive in evolving problem spaces.\n\nCollaborative - You share ideas early and welcome debate.\n\nExperiment-driven - You question conventions and embrace AI-native workflows.\n\nOwnership mentality - You bias toward action and take responsibility for outcomes.\n\nFlux is an equal opportunity employer. We are committed to providing equal employment opportunities to all qualified individuals and do not discriminate on the basis of race, color, religion, sex (including pregnancy, gender identity, and sexual orientation), national origin, age, disability, genetic information, veteran status, or any other characteristic protected by applicable federal, state, or local law. All employment decisions are based on qualifications, merit, and business need.\nPursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records.","description_format":"text","description_chars":4610,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["EDA Software"],"lifecycle":[{"event":"open","at":"2025-12-18T14:40:47Z"},{"event":"close","at":"2026-08-21T02:13:18Z"},{"event":"reopen","at":"2026-08-30T05:49:34Z"}],"visa":[],"liveness":{"score":28,"band":"fade","label":"Fading","p_open":1,"p_active":0.626,"p_room":0.44,"age_days":302,"expected_fill_days":274,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/flux-product-engineer-front-end","json_url":"https://alion.io/job/flux-product-engineer-front-end.json","meta":{"generated_at":"2026-10-17T12:38:24Z","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":16798,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":24079},"rest":"https://alion.io/mcp/rest/get_company?id=24079"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fflux-product-engineer-front-end"},{"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%2Fflux-product-engineer-front-end"},{"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%2Fflux-product-engineer-front-end"},{"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/flux-product-engineer-front-end\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fflux-product-engineer-front-end"}]}
