Then we will be excited to hear from you!\n\n**Who are we?\n\n**Supplios is a fast growing start-up based in Copenhagen, developing an all-in-one supplier portal for global manufacturers.\n\nAs a manufacturer it is highly critical to have a streamlined, compliant and data-driven supply chain. However, most manufacturers manage the majority of their supply chain with spreadsheets, e-mails and with no unified system of record for supply chain related data. Where existing tools fall short, Supplios is designed to manage the ever-growing complexities in manufacturing supply chains.\n\nRead more about us here www.supplios.com.\n\nOur Supplier Portal is already used by customers in both the US and Europe and we are seeing a very strong demand from new customers. Therefore, we are looking for a new colleague to take lead of our Front-End architecture and development.\n\n**Skills & Experience\n\n****JavaScript/TypeScript Proficiency:\n\n**\n\nStrong understanding of JavaScript and TypeScript.\n\nAbility to write clean, maintainable, and efficient code.\n\n**Framework Experience\n\n**\n\nExperience with at least one or more JavaScript/TypeScript frameworks such as Vue, React, Angular, Svelte, Next.js, or Nuxt.js.\n\nSolid understanding of the pros, cons, and tradeoffs of using frameworks, with both client-side and server-side rendering.\n\n**Enterprise Application Experience\n\n**\n\nProven experience working on large enterprise applications, demonstrating scalability and maintainability.\n\nFamiliarity with Single Page Applications (SPA), Progressive Web Applications (PWA), and responsive design.\n\n**Testing & Methodologies\n\n**\n\nFamiliarity with Test-Driven Development, Behavior-Driven Development, or Domain-Driven Design.\n\nProficiency in writing unit tests, integration tests, and end-to-end tests for JavaScript/TypeScript applications.\n\nExperience working in an Agile development environment, using practices such as Scrum or Kanban.\n\n**Good to know\n\n**We have a great office in the heart of Copenhagen (Pilestræde) with lunch, great coffee and plenty of space where we would like you to be as much as possible, yet we also support flexible working hours and remote working when this is needed.\n\nTo have a good time, supporting each other and delivering a world class product along with a world class customer experience is the core of our DNA, and we expect all our colleagues to contribute in building an incredible company culture.\n\nEverything we build immediately serves real people in real companies worldwide that are making products which affect our daily lives, from cars, to food, renewable energy, and much more.","description_format":"text","description_chars":2748,"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":["Flexible
