Members can play, pause and resume watching as much as they want, anytime, anywhere, and can change their plans at any time.\nWho We Are We are the JavaScript Foundations (JSF) team in Warsaw. We are key partners in building the \"UI Paved Road\" at Netflix, operating within a global, virtual organisation that shepherds JavaScript across the entire company - from the browser to Node.js services powering our studio and streaming systems.\nOur Mission Our product isn't a single app - it’s the developer experience itself. While our sibling teams focus on specific layers of the stack - Node.js Platform on server runtime, UI DevEx on browser runtime, and Design Systems on visual components - we tackle the foundational language-level challenges that unify them all. We own the strategy for dependency management, supply chain security, and TypeScript, ensuring the ecosystem remains healthy, secure, and modern across both browser and server.\nWhy It Matters At our scale - serving hundreds of millions members - \"foundational\" means high-impact. Whether it’s automating annual Node.js LTS migrations for thousands of services or defining the patterns for how we share code across the fleet, we measure our success by the collective velocity of every UI engineer at Netflix. We tackle language-level problems so they can focus on entertaining the world.\nAbout This Role\nDeeply understand how developers use JavaScript at Netflix to create the optimal solutions and abstractions for their use cases, and to help drive and evolve recommended practices\n\nCollaborate with teams internally and in the JavaScript community to shepherd and evolve the JavaScript vision at Netflix\n\nProvide and integrate libraries, tools, or workflows that enable developers to build JavaScript software efficiently\n\nReconcile the needs of our internal ecosystem against the trends of the external ecosystem\n\nDefine and improve the dependency management, packaging, and publishing story for Node.js\n\nAddress complex architectural problems with simple, intuitive designs\n\nDrive adoption of new technology into existing complex systems\n\nExcelling In This Role\nYou collaborate effectively with a variety of stakeholder groups: customers, partners, and the external JavaScript community\n\nYou build and maintain strong relationships across stakeholder groups through continuous feedback loops to ensure high alignment in our investments\n\nYou create clarity and drive alignment across stakeholder groups on technical and non-technical initiatives\n\nYou are a curious and proactive learner that seeks to minimize assumptions and seeks to deeply understand before writing code or taking action\n\nYou thrive in an ambiguous environment and can self-manage and self-prioritize your time, energy, and resources\n\nYou are a storyteller and can weave a narrative joining the Netflix ecosystem with the external ecosystem\n\nThe team anchors on the human-facing elements of technology. These elements are emphasized in our Culture Memo and are applied in our day-to-day work. Code is a very small slice of this team's impact.\nInclusion is a Netflix value and we strive to host a meaningful interview experience for all candidates. If you want an accommodation/adjustmentfor a disability or any other reason during the hiring process, please send a request to your recruiting partner.\nWe are an equal-opportunity employer and celebrate diversity, recognizing that diversitybuilds stronger teams. We approach diversity and inclusion seriously and thoughtfully. We do not discriminate on the basis of race, religion, color, ancestry, national origin, caste, sex, sexual orientation, gender, gender identity or expression, age, disability, medical condition, pregnancy, genetic makeup, marital status, or military service.","description_format":"text","description_chars":3979,"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":["Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-10-18T01:20:47Z"}],"visa":[],"liveness":{"score":28,"band":"fade","label":"Fading","p_open":1,"p_active":0.626,"p_room":0.44,"age_days":63,"expected_fill_days":58,"reasons":["conf:1","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/netflix-software-engineer-l45-javascript-foundations","json_url":"https://alion.io/job/netflix-software-engineer-l45-javascript-foundations.json","meta":{"generated_at":"2026-10-23T00:03:24Z","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":93,"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":5888},"rest":"https://alion.io/mcp/rest/get_company?id=5888"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnetflix-software-engineer-l45-javascript-foundations"},{"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%2Fnetflix-software-engineer-l45-javascript-foundations"},{"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%2Fnetflix-software-engineer-l45-javascript-foundations"},{"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/netflix-software-engineer-l45-javascript-foundations\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnetflix-software-engineer-l45-javascript-foundations"}]}
