You'll design and build the interface, run the experiments that lift conversion, and set the bar for craft as the team grows. This role is for someone with a real eye and the discipline to prove it with data. You care about the feel of a transition as much as the lift on a funnel - and you move fast, shipping with AI in the loop. The platform you'll shape Tradesyncer gives futures traders the full infrastructure to scale and improve, not just one tool. You'll own how trade copying, journaling, analytics, expense tracking and risk management feel and convert across the product - and how the marketing site turns visitors into traders. One platform, everything traders need to scale: trade copying, trading journal, analytics, risk management, expense tracking, prop firm tracker, AI coach. Brokers and platforms: NinjaTrader, Tradovate, Rithmic, TradingView, ProjectX, Deepchart, and more. What you'll do * Design and build the front end in React + TypeScript - clean, fast, and wired straight into the product. * Run CRO end to end - instrument funnels, design and ship A/B tests, and lift trial-to-paid with evidence. * Own features end to end - from Figma to shipped, including the last 10% of polish that makes it feel right. * Build and own the design system and component library so quality scales with the team. * Build real-time, data-dense UIs over WebSockets so dashboards and account states update live. * Move fast with AI - Cursor, Claude and AI-assisted workflows are core to how we build, not a novelty., * Based in Amsterdam, on-site preferred, working side by side with the founding team. * Direct impact: your work is the first thing every trader sees, from day one. * Real ownership: a small team where you own entire surfaces. * Full platform access, plus our prop firm partnerships. * Monthly compensation of €4,500 to €6,000, paid reliably every month. * Budget for hardware, tools and learning. Interested? Send your CV, and preferably a portfolio or links to live work, and a short note - the hardest interface you've shipped, and what you'd change about it today. r.kadri@tradesyncer.com ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [To New Frontiers: The Future of Frontend Development](https://www.wearedevelopers.com/videos/404-to-new-frontiers-the-future-of-frontend-development) - [From Zero to Hero: NextJS 13 and Tailwind CSS for Beginners](https://www.wearedevelopers.com/videos/766-from-zero-to-hero-nextjs-13-and-tailwind-css-for-beginners) ## Related Articles - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [How to Find Tech Jobs in Amsterdam](https://www.wearedevelopers.com/magazine/279-how-to-find-tech-jobs-in-amsterdam) - [Software Developer Salary in The Netherlands [2023]](https://www.wearedevelopers.com/magazine/217-software-developer-salary-in-the-netherlands-2023) - [The Netherlands – Europe’s powerhouse for software development?](https://www.wearedevelopers.com/magazine/31-the-netherlands-europe-s-powerhouse-for-software-development) - [How to land a developer job in Amsterdam](https://www.wearedevelopers.com/magazine/36-how-to-land-a-developer-job-in-amsterdam) - [Best Companies in the Netherlands: Top 25 Companies in 2023 ](https://www.wearedevelopers.com/magazine/193-best-companies-in-the-netherlands-top-25-companies-in-2023)
