It combines JavaScript sandboxing with proxy infrastructure, creating unusual engineering challenges across browser APIs, web security, real-time communication, and distributed systems.\nAs a Senior Full-Stack Software Engineer, you will join our Product Engineering team in Amsterdam. This is a genuinely full-stack role: projects regularly cross frontend and backend boundaries.\nYou will own production features from technical design and implementation through testing, release, and maintenance. Your work will include a mix of:\nBuilding in-session interfaces and tools using TypeScript and Vue.js\nDeveloping APIs and backend services using Python, Django, Django REST Framework, Node.js, and Go\nBuilding real-time collaboration features using WebSockets and WebRTC\nDeveloping browser automation, in-session extensions, and security controls\nBuilding integrations with customer and partner systems\nDeveloping MCP and WebMCP capabilities that allow AI agents to interact with Webfuse sessions\nTesting, debugging, deployment, and production maintenance are part of owning a feature - not separate responsibilities handed to another team.\nWe expect you to bring deep expertise in at least one part of the stack and to contribute confidently across the wider platform. As part of a small engineering team, you will have direct influence over technical decisions and how features are built.\nOur team is international and English is our working language. This is an office-first hybrid role: you will work from our Amsterdam office four days per week, with the option to work from home one day per week.\nCandidates must currently be based in the Netherlands. Surfly can provide or transfer Dutch visa sponsorship.\nRequirements\nA bachelor’s or master’s degree in Computer Science, Software Engineering, or a closely related technical field\nAt least five years of professional software engineering experience building and maintaining production web applications\nDirect experience with Python, Django, Vue.js, Node.js, or Go\nStrong full-stack development experience, with deeper expertise in either backend or frontend engineering\nProfessional experience with server-side development and TypeScript-based frontend development\nExperience designing, building, and maintaining APIs or backend services\nStrong engineering fundamentals, including automated testing, debugging, code review, Git, and maintainable software design\nThe ability to investigate complex problems across browser, frontend, and backend systems\nA track record of owning software beyond its initial implementation, including rollout, debugging, and production maintenance\nClear written and verbal communication in English\nCurrently based in the Netherlands and able to work from our Amsterdam office four days per week\nA GitHub profile containing publicly viewable code that you wrote\nNice to have:\nBrowser automation experience with Playwright, Puppeteer, or the Chrome DevTools Protocol\nKnowledge of CSP, cookies, SameSite, SRI, or cross-origin isolation\nExperience with WebSockets, WebRTC, or browser extension development\nExperience with PostgreSQL, Redis, microservices, containers, or deployment pipelines\nExperience with MCP, WebMCP, or other AI-agent integrations","description_format":"text","description_chars":3403,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Netherlands","iso":"NL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Customer Support & Help Desk Software"],"lifecycle":[{"event":"open","at":"2026-09-16T23:32:55Z"},{"event":"open","at":"2026-09-25T12:23:41Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":0.4,"p_active":0.45,"p_room":0.28,"age_days":73,"expected_fill_days":26,"reasons":["seen:73","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/vuejobs-senior-full-stack-software-engineer-webfuse","json_url":"https://alion.io/job/vuejobs-senior-full-stack-software-engineer-webfuse.json","meta":{"generated_at":"2026-10-18T10:38:16Z","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":15760,"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":692819},"rest":"https://alion.io/mcp/rest/get_company?id=692819"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvuejobs-senior-full-stack-software-engineer-webfuse"},{"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%2Fvuejobs-senior-full-stack-software-engineer-webfuse"},{"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%2Fvuejobs-senior-full-stack-software-engineer-webfuse"},{"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/vuejobs-senior-full-stack-software-engineer-webfuse\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvuejobs-senior-full-stack-software-engineer-webfuse"}]}
