Providing professional design methods and practices, the team helps improve user experience and working efficiency of these products and areas.\n1. Reshape the design-to-engineering workflow - Partner with product designers and client engineers to identify friction in the handoff, and close the gap through better processes and shared practices\n2. Explore aggressively - Run multiple feasibility tracks for new workflows and tooling in parallel, rather than picking one and grinding\n3. Close the loop into production - Lead how design-delivered code integrates with the mainline codebase, partnering with engineering to systematize design system components, performance, and accessibility into production-quality implementations that improve user experience\n4. Build AI design tooling - Architect and ship internal AI tooling (agents, design system plugins, code-generation pipelines, prototyping platforms) that lets every designer move from idea to high-fidelity prototype to shippable code with leverage\n5. Drive technical direction across design and product - Partner with engineering leads on architecture, design system evolution, and tooling roadmap. Translate design intent into engineering trade-offs, and vice versa\n任职要求 / Requirements\nMinimum Qualifications：\n- With engineering experience shipping production mobile or full-stack systems\n- Full-stack capability, with deep expertise in at least one mobile stack (iOS / Swift, SwiftUI or Android / Kotlin, Compose) and working knowledge of backend (APIs, services, data layer)\n- Deep, hands-on use of AI coding agents (Cursor, Claude Code, etc.) with efficient token budgeting, agentic workflows, and a track record of shipping with them; products you built independently end-to-end strongly preferred\n- Experience building or shipping AI product features or agent-based workflows\n- Ability to solve complex problems with simple solutions\n- Founding or early-team experience, or clear evidence of having shaped a team/practice from scratch\n- Strong product thinking, able to drive ambiguous problems all the way to shipped impact\nPreferred Qualifications\n- Background spanning both design and engineering (designer-turned-engineer, or engineer with formal design training or shipped design work)\n- Public craft signal - open source contributions, conference talks, published tooling, or a notable public presence around your work\n- Experience with Lynx, or other cross-platform mobile frameworks\n- Experience shipping social, creator, or content products at scale\n- Passion for TikTok and creator communities","description_format":"text","description_chars":2791,"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":false,"industries":["Media & Entertainment","Advertising","Social Commerce","Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-09-26T11:45:02Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 547 · green card filings: 242","filings_12m":547,"filings_prev_12m":889,"green_card_filings_12m":242,"median_offered_wage_usd":210130,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":217}],"liveness":{"score":28,"band":"fade","label":"Fading","p_open":1,"p_active":0.771,"p_room":0.36,"age_days":149,"expected_fill_days":99,"reasons":["conf:0","velocity","win:tail","crowd:brand"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/tiktok-senior-design-engineer-founding-engineer-tiktok","json_url":"https://alion.io/job/tiktok-senior-design-engineer-founding-engineer-tiktok.json","meta":{"generated_at":"2026-11-01T13:29:16Z","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":20693,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":47},"rest":"https://alion.io/mcp/rest/get_company?id=47"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftiktok-senior-design-engineer-founding-engineer-tiktok"},{"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%2Ftiktok-senior-design-engineer-founding-engineer-tiktok"},{"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%2Ftiktok-senior-design-engineer-founding-engineer-tiktok"},{"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/tiktok-senior-design-engineer-founding-engineer-tiktok\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftiktok-senior-design-engineer-founding-engineer-tiktok"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1301383}},{"tool":"search_jobs","arguments":{"company":"tiktok.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1301383},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
