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\nYou'll build the iOS experience for Hark: a native app that brings a real-time, multimodal AI agent into people's pockets.\nThat means shipping an app that feels instant, handles streaming AI responses gracefully, and integrates voice, text, and vision into a single coherent experience. The bar is high: this is the primary way millions of people will interact with Hark.\nThis is a high-ownership role on a small team. You'll work directly with designers, platform engineers, and the people building the models. What you ship will define how Hark feels in someone's hand.\nResponsibilities\nBuild and own the Hark iOS app. Architecture, UI, performance, and the end-to-end experience.\nShip features that integrate real-time AI capabilities: streaming responses, voice input, tool invocations, and multimodal interactions.\nWork closely with designers to craft interfaces that feel fast, polished, and trustworthy. Sweat the details.\nOptimize for performance at every layer: startup time, animation smoothness, memory efficiency, and network latency.\nOwn components end-to-end, from design and implementation through testing, launch, and iteration.\nCollaborate with platform and backend engineers on APIs, data contracts, and integration with the agent runtime.\nInstrument what you ship. Track performance, catch regressions, and improve based on real-world usage.\nRequirements\nStrong expertise in Swift, with deep knowledge of UIKit and SwiftUI, and a solid understanding of iOS system design.\nProven ability to build high-performance, responsive mobile applications, with experience optimizing for latency, memory, and real-time interactions.\nExperience designing and shipping intuitive, high-quality user experiences, with strong attention to detail and product craft.\nFamiliarity with concurrency patterns (async/await, Combine) for building real-time, interactive applications.\nExperience integrating with backend systems and AI-powered services (REST, streaming APIs), ensuring smooth and reliable data flow.\nDemonstrated ability to own features end-to-end, from initial concept and architecture through implementation and deployment.\n5+ years of iOS engineering experience.\nBonus Qualifications\nExperience building or contributing to AI-powered or agent-driven applications, especially involving voice, multimodal input, or real-time interaction.\nStrong product intuition, with the ability to translate emerging AI capabilities into user-facing experiences that feel natural and useful.\nExperience working in early-stage or 0-to-1 environments, with a track record of shipping quickly and iterating based on user feedback.\nFamiliarity with the Apple ecosystem, including frameworks such as AVFoundation, Core ML, or real-time media processing.\nComfortable working across the stack or collaborating closely with backend and AI teams to deliver end-to-end features.\nHigh bar for engineering craft, with a track record of building polished, performant, and reliable mobile products.\nCompensation\nThe US base salary range for this full-time position is between $180,000 - $450,000 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 and benefits depending on the specific role. This information will be shared if an employment offer is extended.","description_format":"text","description_chars":4151,"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":["LLM & Generative AI","AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-03-19T20:52:00Z"}],"visa":[],"liveness":{"score":25,"band":"fade","label":"Fading","p_open":1,"p_active":0.684,"p_room":0.36,"age_days":210,"expected_fill_days":113,"reasons":["conf:2","velocity","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":450000,"is_top_pay":true},"html_url":"https://alion.io/job/hark-mobile-ios-engineer","json_url":"https://alion.io/job/hark-mobile-ios-engineer.json","meta":{"generated_at":"2026-10-16T09:59:01Z","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":8271,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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-mobile-ios-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-mobile-ios-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-mobile-ios-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-mobile-ios-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhark-mobile-ios-engineer"}]}
