By partnering with the best fiat-to-crypto payment gateways and presenting them in a single plugin their users can then buy crypto easily in-platform when needed. This is one of the most important intersections for web3/meta.\nWe are looking for a Fullstack Engineer with a keen interest in the development of modern web platforms, as well as the ambition for personal growth and innovation. As part of a cross-functional team, you’ll be taking a lead on some of the most important and core parts of our platform.\nAbout the Team\nWe're a distributed team of engineers who believe in full ownership - not just of code, but of outcomes. Currently 6 strong and growing to 8, our team spans multiple countries and time zones, with a growing presence in Amsterdam.\nWe're a true full-stack team. That means everyone has working knowledge across the stack, can pick up any part of the product when needed, and collaborates directly with product to shape what we build - not just how we build it. There are no silos here. You won't be handed a spec and asked to execute; you'll be expected to question, contribute, and own.\nWe move fast, hold high engineering standards, and care deeply about the reliability and correctness of the systems we build. If you thrive in environments where your decisions have real impact and you're trusted to see a problem through from discovery to production, you'll fit right in.\nRequirements\nWe're looking for a Full Stack Software Engineer at the upper mid-level - someone who is beyond executing tasks and is ready to drive meaningful technical work end-to-end.\nYou'll spend roughly 70% of your time on backend (Node.js, TypeScript, APIs, cloud infrastructure) and 30% on frontend (React, TypeScript). You're not expected to be a specialist in both - but you are expected to be genuinely capable across the stack and comfortable context-switching between the two.\nThis is a role for someone who owns their work. That means being involved from the moment a problem is identified, helping break it down, making sound architectural decisions, shipping it, and making sure it stays healthy in production.\nWhat You'll Do\nDesign and build robust, scalable backend services and APIs using Node.js and TypeScript\n\nDevelop and maintain React-based frontend interfaces that are performant and maintainable\n\nCollaborate closely with product and design to shape features from discovery through to delivery - not just implementation\n\nTake ownership of your work end-to-end: scoping, building, shipping, monitoring\n\nContribute to and improve CI/CD pipelines, deployment processes, and cloud infrastructure\n\nWrite secure, well-tested, production-ready code with real uptime requirements\n\nParticipate in code reviews, architectural discussions, and technical decision-making\n\nHelp maintain the reliability and observability of production systems - and respond when things go wrong\n\nWhat We're Looking For\nYou must have:\nStrong, production-proven experience with JavaScript/TypeScript - you know the language and ecosystem deeply, not just the basics\n\nSolid backend experience. Node.jsis most preferable, but not a blocker if you bring excellent backend experience with another prominent stack (Java, Go, or Python)\n\nSolid frontend experience building and maintaining real applications - React.jspreferred, but strong experience with another popular framework (Vue, Angular) is equally welcome\n\nHands-on experience with cloud infrastructure - AWS, GCP, or Azure - in a production environment\n\nA working understanding of CI/CD pipelines and modern deployment practices\n\nA security-conscious approach to development - you think about attack surfaces, data handling, and least-privilege access as a matter of habit\n\nHigh ownership, end to end - you don't wait to be told what to do next, you lead topics from problem to production, and you don't consider your job done when the code is merged\n\nGenuine interest in crypto and in Onramper as a product - you're excited about the space and want to go deep, not just ship tickets\n\nThe ability to work closely with product teams - you can translate between technical constraints and business needs, and you're comfortable pushing back when necessary\n\nIt would be great if you also have:\nAWS experience specifically (preferred over other cloud platforms)\n\nTerraform experience for infrastructure-as-code\n\nKubernetes for container orchestration\n\nExperience in fintech - particularly payments, transactions, or regulated financial systems\n\nBased in or willing to relocate to Amsterdam, Netherlands(preferred but not required)\n\nWhat a Strong Candidate Looks Like\nYou've built and shipped production systems that real users depend on. You've been in an incident, diagnosed it, fixed it, and made sure it doesn't happen again. You've sat with a product manager to figure out what to build - not just been handed a ticket. You write TypeScript that actually leverages the type system. You think about what happens when your code fails, not just when it works.\nYou're not the most senior engineer in the room, but you don't need to be - you're the kind of engineer who makes the people around them better.\nWhy This Role\nWork on systems that process real financial transactions at scale\n\nA team that trusts you to own your work from day one\n\nDirect influence on technical direction - no layers of approval to get things done\n\nA genuinely distributed, collaborative team culture where quality and craftsmanship matter\n\nA growing Amsterdam presence - be one of the foundational members of that hub","description_format":"text","description_chars":6054,"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":"Netherlands","iso":"NL","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Blockchain & Crypto","Cryptocurrencies","Crypto Exchanges","Crypto Payments"],"lifecycle":[{"event":"open","at":"2026-10-14T07:34:03Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.248,"p_room":0.28,"age_days":184,"expected_fill_days":67,"reasons":["conf:4","win:tail","crowd:"],"computed_at":"2026-10-14T15:22:21Z"},"pay":null,"html_url":"https://alion.io/job/onramper-software-engineer-fullstack-2","json_url":"https://alion.io/job/onramper-software-engineer-fullstack-2.json","meta":{"generated_at":"2026-10-14T15:22:21Z","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":19382,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":175776},"rest":"https://alion.io/mcp/rest/get_company?id=175776"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fonramper-software-engineer-fullstack-2"},{"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%2Fonramper-software-engineer-fullstack-2"},{"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%2Fonramper-software-engineer-fullstack-2"},{"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/onramper-software-engineer-fullstack-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fonramper-software-engineer-fullstack-2"}]}
