One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory.\nWe're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines. While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world.\nTo get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems.\nAbout the Role\nThe Embedded Software team is looking for a Frontier UX Engineer to build the software that turns design intent into interfaces people can pick up and use. You will work closely with Design, taking ideas, use cases, and specifications from early prototype through a world class shipped product, pushing the UI experience to its limit.\nMuch of the work has no precedent, requiring comfort with unclear requirements and problems that cross design and several software layers. We care a lot about how the product feels to use, and we want someone who shares that mindset.\nResponsibilities\nTurn design specifications, use cases, and rough ideas into shipping interfaces, from early prototype through production on real hardware\nOwn execution: take a prototype the whole way to something that ships, with the quality bar held at each step\nFind where the design language outruns the platform, and push the UI software at every layer needed to close the distance\nAdvise designers on what the system is actually capable of, early enough for it to change the design\nShape the UI runtime and system architecture with requirements drawn from real designs rather than hypotheticals\nOwn the end-to-end development of user experiences alongside design, firmware, and hardware partners\nRequirements\n8+ years of professional UI software development experience\nDirect experience building user interfaces that run on a device, not only cloud-backed mobile apps\nExperience working inside or closely with a design team\nExperience with rapid prototyping, able to build a realistic interactive prototype in days\nDeep runtime knowledge of at least one major UI framework (e.g. UIKit, SwiftUI, Core Animation, Jetpack Compose, Flutter, or a web-based rendering engine)\nProficient in at least one of: C, C++, Rust, Swift, or Dart, and the ability to trace code across language and process boundaries\nAbility to work with incomplete information in uncharted territory, driving quality and results\nBonus Qualifications\nDirect experience with or exposure to embedded system or operating system work (e.g. system daemons, IPC, HAL, drivers, firmware)\nExperience shipping system-level UI apps on embedded devices\nExperience shipping a system-level UI framework or graphics stack on iOS, Android, Linux and/or VxWorks\nContributions to open source UI libraries widely adopted by the community\nExperience with design tools (e.g. Figma, Origami, Rive, or Principle) and turning their output into production animations\nExperience building UI design tools (e.g. component libraries, visual or node-graph editors, or interactive prototyping environments)\nExperience building interfaces driven by voice, vision, sensor, or ML models, including generated interfaces\nCompensation\nThe US base salary range for this full-time position is between $150,000 - $350,000 annually.\nThe pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.","description_format":"text","description_chars":3891,"description_truncated":false,"requirements":{"experience_years_min":8,"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":["LLM & Generative AI","AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-09-06T01:44:46Z"}],"visa":[],"liveness":{"score":79,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.881,"p_room":0.9,"age_days":48,"expected_fill_days":113,"reasons":["conf:1","velocity","win:mid"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":350000,"is_top_pay":true},"html_url":"https://alion.io/job/hark-frontier-ux-engineer","json_url":"https://alion.io/job/hark-frontier-ux-engineer.json","meta":{"generated_at":"2026-10-23T21:55:18Z","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":4340,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":764},"rest":"https://alion.io/mcp/rest/get_company?id=764"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhark-frontier-ux-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%2Fhark-frontier-ux-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%2Fhark-frontier-ux-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/hark-frontier-ux-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhark-frontier-ux-engineer"}]}
