You'll own frontend work across multiple codebases - an internal admin tool, embeddable payment widgets, and publisher-hosted transaction pages - all securely handling real money, real compliance requirements, and real users.\nThis isn't a \"build marketing pages\" gig. You'll be working with GraphQL APIs backed by Go microservices, writing code that touches invoicing, payouts, KYC verification, and fraud detection. The work matters and the stakes are real.\nWhat You'll Work On\n Admin Tools (React, Vite, Chakra UI, Apollo Client): Internal tooling used by operations teams to manage accounts, transactions, and payment methods. Turborepo monorepo with a GraphQL BFF layer.\n Payment Widgets (Next.js, React, Tailwind CSS, Server Components): Embeddable checkout, payout, and KYC flows where every millisecond of load time impacts conversion. Active rewrite with a performance-first architecture.\n Publisher-Hosted Pages (Next.js, Chakra UI, SSR): Multi-tenant, themeable transaction pages served under publisher-branded domains with CNAME routing and per-publisher customization.\nDay-to-Day\nShip features and fixes across multiple TypeScript/React codebases.\nWrite and maintain unit tests (Vitest + React Testing Library) and help with Playwright e2e tests (Python/pytest).\nWork with a GraphQL API layer that translates between the frontend and Go microservices (accounts, payments, invoicing, wallets).\nRun the full local stack via Docker Compose (makeworld) with hot-reload - no waiting for builds.\nMaintain or improve test coverage.\nCollaborate on a small team where you'll have real ownership and influence over frontend architecture.\nYou Should Have\nReact applications - you've shipped features that real users depend on.\nTypeScript proficiency.\nTesting discipline - experience with Vitest or Jest and React Testing Library or similar.\nComponent library experience - you've worked with Chakra UI, MUI, or similar design systems and can extend them without fighting them.\nLinux shell proficiency - comfort navigating the file system, using common utilities, and basic scripting.\nBonus Points\nExperience with payment/fintech UIs - checkout flows, KYC, compliance screens.\nFamiliarity with Playwright or similar e2e frameworks.\nDocker comfort - you don't panic when the local stack is containerized.\nPython literacy. Enough to read and write Playwright test scripts.\nGo literacy. Enough to read the backend services and understand the APIs you will be calling.\nGraphQL experience - you've worked with Apollo Client or a similar GraphQL client and understand queries, mutations, caching, and schema design.\nExperience building UIs for role-based access control (RBAC) or complex permission systems.\nYou've worked on multi-tenant/white-label products with theming systems.\nExperience working in monorepos (Turborepo, Nx, or similar).\nWhat We're NOT Looking For\nSomeone who needs a design system handed to them pixel-perfect - you'll make pragmatic UI decisions in lieu of hi fidelity mockups.\nA \"framework tourist\" chasing the latest meta-framework - we need someone who ships, not someone who rewrites.\nSomeone uncomfortable with legacy code - parts of the codebase are being actively migrated and you'll need to work in both old and new patterns gracefully.\nWhy This Role\nSmall team, big impact - you won't be pixel-pushing in a feature factory. You'll shape frontend architecture across multiple products.\nReal domain complexity - payments, compliance, multi-currency, fraud detection. The problems are genuinely interesting.\nModern stack, active migration - you get to help move things forward rather than maintain a frozen codebase.\n Strong engineering culture - enforced coverage thresholds, pre-commit hooks, CI gates, deployment on merge. The team cares about quality and process aerodynamics.","description_format":"text","description_chars":3977,"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":["Payment Processing & Gateways","Money Transfer & Remittances"],"lifecycle":[{"event":"open","at":"2026-10-08T23:51:27Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.106,"p_room":0.28,"age_days":191,"expected_fill_days":26,"reasons":["conf:2","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/thunes-react-software-engineer","json_url":"https://alion.io/job/thunes-react-software-engineer.json","meta":{"generated_at":"2026-10-16T18:32:35Z","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":3703,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":5845},"rest":"https://alion.io/mcp/rest/get_company?id=5845"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthunes-react-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%2Fthunes-react-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%2Fthunes-react-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/thunes-react-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthunes-react-software-engineer"}]}
