We focus on driving acquisition, optimizing conversion, improving retention, and delivering seamless commerce experiences that fuel Spotify’s growth and bring fans closer to the creators they love.\nSpotify's messaging platform reaches over 1.4 billion users and delivers tens of billions of messages across email, push, and in-app channels. Beacon is the team behind Quicksilver, the internal platform operators use to create, localize, target, and launch those messages. We're looking for a Senior Engineer to help us build intuitive, reliable tools that power how Spotify communicates with listeners at scale.\nWhat You'll Do\nBuild and evolve Quicksilver UI, Spotify's multi-channel messaging platform, where operators author, preview, and deliver in-app messages, emails, and push notifications across markets and locales.\nOwn frontend features end-to-end, from component design and implementation in React and TypeScript through server-side creative rendering.\nWork across the stack when needed, including debugging Java and Apollo services, evolving gRPC, Protobuf, and REST API contracts, tracing data through BigQuery, and improving pipeline output.\nSupport multi-market and localization workflows, helping creatives render reliably across locales and enabling smooth new-market launches.\nPartner with product and design to shape features and improvements based on operator needs.\nImprove the developer experience through stronger testing infrastructure, build performance, component documentation, and integration tooling.\nContribute to architectural decisions and technical direction as the platform evolves.\nWho You Are\nYou have experience building complex web applications with TypeScript and modern UI frameworks, including React or similar technologies.\nYou understand state management, GraphQL and Apollo, component-scoped styling, and reusable component-library design.\nYou have built tools or platforms for internal users and care about creating intuitive, reliable operator experiences.\nYou are comfortable working across frontend and backend systems, including reading or modifying Java services and working with API contracts such as gRPC, Protobuf, or REST.\nYou can work with Scala/Python when pipelines or APIs need attention and navigate cloud infrastructure and data tools such as GCP, GKE, BigQuery, or GCS.\nYou make thoughtful decisions about technical debt and can clearly communicate the tradeoffs between maintaining, improving, and migrating systems.\nYou have experience working across shared codebases and understand the collaboration needed when teams depend on common components and services.\nYou may also bring experience with data pipelines, LLM applications such as RAG or vector search, or server-side rendering.\nWhere You'll Be\nWe offer you the flexibility to work where you work best! For this role, you can be within the North Americas region as long as we have a work location.\nThis team operates within the Eastern Standard time zone for collaboration.","description_format":"text","description_chars":3144,"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":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Advertising","Music Industry","Podcasting","Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-10-09T18:42:21Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 95 · green card filings: 51","filings_12m":95,"filings_prev_12m":164,"green_card_filings_12m":51,"median_offered_wage_usd":205034,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+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":45}],"liveness":{"score":42,"band":"fade","label":"Fading","p_open":1,"p_active":0.566,"p_room":0.75,"age_days":46,"expected_fill_days":52,"reasons":["conf:2","stale_co","velocity","win:late"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/spotify-senior-fullstack-engineer-messaging-platform","json_url":"https://alion.io/job/spotify-senior-fullstack-engineer-messaging-platform.json","meta":{"generated_at":"2026-10-12T17:34:58Z","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":28245,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":57},"rest":"https://alion.io/mcp/rest/get_company?id=57"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fspotify-senior-fullstack-engineer-messaging-platform"},{"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%2Fspotify-senior-fullstack-engineer-messaging-platform"},{"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%2Fspotify-senior-fullstack-engineer-messaging-platform"},{"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/spotify-senior-fullstack-engineer-messaging-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fspotify-senior-fullstack-engineer-messaging-platform"}]}
