Role Description As a full-stack engineer, you work across the whole gift card product: the screens customers use and the services running behind them. Day to day, you will: - Own features from discovery to production: Partner directly with other teams to scope ideas, design architectures, and ship features - collaborating closely with senior peers while leveraging AI tools to iterate with extreme speed. - Build and refine the gift card experience, from buying a card to redeeming it. - Develop the back-end that powers it: APIs, services, and data models. - Work on the partner side too, the B2B self-serve product and the embeddable widgets that let other companies plug Joy_ in. - Keep the codebase healthy, with shared components, design tokens, sensible tests, and an eye on performance and accessibility. Qualifications - 3+ years building modern web products, full-stack. - Genuinely comfortable on both the front-end and the back-end. - A deep sense of product ownership. - An exceptional teammate. - An elite execution mindset. - A real eye for detail. - You think in systems. - A pragmatic approach to quality. - Excellent spoken and written English. German is a plus, not a must. Requirements - Show us what you have built and shipped. - You don't wait to be told what each step is. When you see a broken piece, you take it upon yourself to fix it. - You care about the product actually working, not just clearing backlog tickets. - Proactively communicates, communicates clearly in a remote async environment. - Enjoys code reviews as a tool for teaching and learning. - Uses modern tools (like AI terminal agents) to strip away boilerplate and focus on architecture, security, and user delight. - Cares deeply about typography, layout, and motion. - Comfortably navigates Figma to extract design intent, tokens, and variables. - Weighs up data models, API design, and performance rather than working around them. - Unit and e2e tests where they earn their keep, with steady attention to performance and accessibility. Benefits - Real responsibility: Work across the whole product and sit close to the founders every day. - Growth: Build on the frontier of AI commerce alongside senior operators and engineers who have scaled before. - Autonomy: Remote-first, with the freedom to work how you work best. - Meaningful equity: We want you to win with us. - Real impact: Watch what you build go live in front of a whole country.
