Buying and selling fashion feels simple, joyful, and personal, while every item tells its own story. Poshmark empowers sellers to grow meaningful businesses, keeps fashion in circulation longer, and gives shoppers access to unique and trusted finds, from everyday pieces to one-of-a-kind vintage and luxury.\nPoshmark is looking for a Senior Web Engineer II to join our Buyer Pod. We are the team responsible for the core user journey: feed, discovery, search, and listing details. We don’t just build interfaces; we build the engine that helps millions of users find and buy what they love.\nWe are looking for an engineer who values the \"how\" as much as the \"what.\" You should be someone who understands the browser’s rendering pipeline and DOM underpinnings deeply, ensuring that our migration from Vue 2 to Vue 3 is not just a version bump, but a leap forward in performance and code quality.\nCore Responsibilities\nArchitect & Execute: Lead small engineering pods to take complex features from discovery to production-scale delivery.\n\nThe Vue Migration: Act as a key driver in our transition from Vue 2 to Vue 3, leveraging the Composition API and modern build tools (Vite/Webpack).\n\nHigh-Performance UI: Build responsive, accessible, and high-performance web applications with a focus on Core Web Vitals and efficient state management.\n\nDesign Partnership: Collaborate closely with Product and Design to ensure every pixel serves the user experience. You should bring a strong \"sense of taste\" to everything you build.\n\nTechnical Mentorship: Influence the technical roadmap and mentor junior/mid-level engineers through code reviews and architecture discussions.\n\n90-Day Success Metrics\nImmediate Impact: Contribute production-ready code to both our legacy and modern environments within your first 30 days.\n\nMigration Milestone: Successfully migrate a complex module or shared component from Vue 2 to Vue 3.\n\nFeature Ownership: Lead the technical execution of a new buyer-facing feature, ensuring it meets our standards for performance and design polish.\n\n12-Month Success Metrics\nArchitecture Evolution: Propose and implement structural improvements to our web stack that measurably improve developer velocity and site speed.\n\nSystem Expert: Become the primary technical point of contact for our search and discovery front-end architecture.\n\nTeam Growth: Level up the team’s collective knowledge of browser internals and modern JavaScript best practices.\n\nDesired Skills\n5+ years of software development experience, with a focus on high-scale web applications.\n\nUnder the Hood Knowledge: Deep understanding of JavaScript fundamentals (Event Loop, DOM API, browser rendering) beyond framework-specific abstractions.\n\nVue Specialist: Proven experience with Vue 2 and Vue 3. Experience navigating the friction of migrating between the two is highly preferred.\n\nLeadership: Experience leading small teams or project \"pods\" and a track record of driving features to completion.\n\nProduct Intuition: A sharp eye for UI/UX and a passion for creating \"great\" web design rather than just \"functional\" code.\n\nThe Stack: Familiarity with modern build tools (Vite, Webpack), RESTful APIs, and distributed systems.","description_format":"text","description_chars":3507,"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":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Marketplaces","Secondhand"],"lifecycle":[{"event":"open","at":"2026-02-11T18:52:41Z"},{"event":"close","at":"2026-08-13T11:24:52Z"},{"event":"reopen","at":"2026-08-30T13:17:43Z"},{"event":"open","at":"2026-09-25T19:21:05Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 6 · green card filings: 2","filings_12m":6,"filings_prev_12m":19,"green_card_filings_12m":2,"median_offered_wage_usd":196250,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+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":3}],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.473,"p_room":0.28,"age_days":247,"expected_fill_days":94,"reasons":["conf:3","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":212745,"is_top_pay":true},"html_url":"https://alion.io/job/poshmark-sr-software-engineer-ii-web","json_url":"https://alion.io/job/poshmark-sr-software-engineer-ii-web.json","meta":{"generated_at":"2026-10-18T02:17:35Z","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":3761,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":5858},"rest":"https://alion.io/mcp/rest/get_company?id=5858"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fposhmark-sr-software-engineer-ii-web"},{"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%2Fposhmark-sr-software-engineer-ii-web"},{"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%2Fposhmark-sr-software-engineer-ii-web"},{"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/poshmark-sr-software-engineer-ii-web\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fposhmark-sr-software-engineer-ii-web"}]}
