We help people give valuable things a new life, making the experience simple, transparent and rewarding.\n\nWe bring together specialist knowledge, thoughtful technology and genuine care for our customers. By helping more items stay in circulation, we create value for people and make a positive impact at the same time.\nAbout the Team\nAt Vintage.com, technology is how we scale our impact. Every part of the customer journey - from sending in pre-loved items to getting paid - is powered by the systems we design, the products we build and the data we unlock. Our Technology team is driving greenfield product development, testing fresh ideas and building modern, scalable platforms that set the standard for re-commerce.\nYou'll join our web team, working alongside front-end engineers and our Software Engineer in Test, and reporting to the Lead Frontend Engineer. It's a team where curiosity meets craft: we blend creativity, technical excellence and a strong product mindset to create experiences that feel simple, rewarding and built to last.\nWhy This Role Matters\nWhy the role exists\n\nWe're looking for a hands-on Frontend Software Engineer who can own front-end craft and extend it end to end - from the interfaces our customers use to the Cloudflare Workers and light backend services that power them.\nThis is an individual contributor role with plenty of influence. You'll build with React and TypeScript, work on API routes, integrations and edge logic using Cloudflare Workers, and help make AI-first, verify-second engineering the team's default.\nYou'll partner with the Lead Frontend Engineer on architecture, with Product and Design on user experience, and with our Software Engineer in Test on quality. You'll set direction through the quality of your code, reviews and judgement, rather than through formal authority.\nWe're looking for someone who asks why, not just what. You'll be curious about our customers and commercial goals, challenge assumptions constructively and help us spot valuable opportunities before they arrive as tickets. This is a UK-based hybrid role, including time with the team in Leeds, and may include occasional travel to our European and other international locations as we grow.\nWhat success looks like\nShip polished, accessible and high-performing customer experiences built on strong React and TypeScript foundations.\nDeliver features end to end, including the Cloudflare Workers, APIs and integrations behind the interface.\nUse AI tooling as a genuine development partner while checking, testing and improving every output before it ships.\nBuild quality in from the start through testable code, unit and component coverage, and close partnership with our Software Engineer in Test.\nRaise the technical bar for front-end craft, edge architecture and full-stack judgement across the web team.\nTurn customer and business insight into better product decisions, not just completed tickets.\nWhat You’ll Do\n\nCustomer experience and front-end craft\n\nBuild and maintain customer-facing experiences. We currently use Astro and React, but prioritise selecting the right tool for each challenge over adherence to any single framework.\nTurn design intent into polished, resilient interfaces, partnering closely with Product and Design.\nOwn responsive layouts, cross-browser compatibility and progressive enhancement across our brand portfolio.\nBuild accessibility (WCAG), Core Web Vitals, component quality and sensible front-end caching into everyday engineering decisions.\nFull-stack and edge delivery\nDeliver features end to end across our Cloudflare Workers stack-API routes, edge logic, integrations-using Wrangler, D1, KV and R2.\nBuild and maintain integrations with forms, CRM and marketing tools such as HubSpot, and headless CMS platforms such as Storyblok.\nMake sound architectural decisions on the edge platform, leveraging Cloudflare's caching, KV and CDN to keep our infrastructure lean.\nConsider internationalisation and localisation as our products and edge logic adapt for different markets.\nAI-first, quality-first engineering\nUse agentic AI tooling, including Claude Code, GitHub Copilot, Cursor or similar, for scaffolding, refactoring, debugging and documentation.\nTreat AI output as a starting point: run type-checks and tests, verify API and library claims against official documentation, and keep human judgement around any meaningful risk.\nWrite your own unit and component tests with Vitest, React Testing Library or similar, and partner with our Software Engineer in Test on end-to-end, visual regression and accessibility automation.\nIntegrate work cleanly through Git, GitHub Actions and our Jira-based Agile workflow, contributing thoughtfully to planning, stand-ups and retrospectives.\nTechnical leadership and continuous improvement\nShape front-end and edge architecture through high-quality code, constructive reviews and mentoring by example, working with the Lead Frontend Engineer on strategic decisions.\nImprove the codebase and team workflows, staying current with the front-end and AI landscape and bringing back credible, proven ideas.\nWrite clear, structured code and documentation that both people and AI agents can understand and work with.\nWhat You’ll Bring\nEssential\nSubstantial hands-on experience as a front-end-focused full-stack engineer, with a track record of senior-level ownership. This is often built over five or more years, but depth and judgement matter more than an exact number.\nStrong, idiomatic React and confidence across the modern JavaScript and TypeScript ecosystem.\nA strong grasp of front-end craft, including UI and UX sensibility, responsive design, cross-browser compatibility, progressive enhancement and maintainable component architecture.\nConfidence extending into backend development through Cloudflare Workers or an equivalent edge or serverless platform, plus Node-based API services.\nPractical, regular use of AI coding assistants such as Claude Code, GitHub Copilot or Cursor, with good judgement about when to trust, verify or reject their output.\nExperience with a headless CMS such as Storyblok and third-party integrations, including forms and CRM or marketing platforms such as HubSpot.\nA working understanding of accessibility, Core Web Vitals and caching across the browser, CDN and edge as everyday engineering concerns.\nA habit of writing your own unit and component tests using Vitest, React Testing Library or similar, alongside effective collaboration with a dedicated quality function.\nConfidence with Git, Agile delivery and CI/CD pipelines such as GitHub Actions.\nSound architectural judgement, clear communication and the confidence to shape technical direction without formal authority.\nA proactive mindset: you investigate, ask why and propose better options rather than waiting for a ticket to define every next step.\nHelpful\nExperience with internationalisation or localisation in front-end or edge applications.\nExposure to agentic AI workflows or MCP-based tooling, such as Playwright MCP or Storyblok MCP.\nExperience partnering with a QA or SDET function on end-to-end, visual regression or accessibility automation.\nFamiliarity with performance testing tools such as Lighthouse or similar..\nA background in e-commerce or re-commerce platforms.\n Qualifications\nNo specific qualifications are required. We care about the work you've done, the judgement you bring and how you keep learning.\n\nLiving Our Values\n\nIn this role, living our values means:\nPut the customer and the wider business outcome at the heart of technical decisions.\nTake ownership, follow through and care about the quality of what reaches production.\nWork openly with Engineering, Product, Design and Quality, sharing context and knowledge as you go.\nStay curious, challenge assumptions constructively and keep learning as the technology landscape changes.\nUse sound judgement and integrity, especially when AI can move quickly but still needs thoughtful human verification.","description_format":"text","description_chars":8073,"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 Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Secondhand"],"lifecycle":[{"event":"open","at":"2026-10-23T23:49:05Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":20,"reasons":["conf:3","win:early"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/vintage-senior-frontend-software-engineer","json_url":"https://alion.io/job/vintage-senior-frontend-software-engineer.json","meta":{"generated_at":"2026-10-25T18:09:09Z","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":25977,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":684797},"rest":"https://alion.io/mcp/rest/get_company?id=684797"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvintage-senior-frontend-software-engineer"},{"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%2Fvintage-senior-frontend-software-engineer"},{"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%2Fvintage-senior-frontend-software-engineer"},{"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/vintage-senior-frontend-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvintage-senior-frontend-software-engineer"}]}
