At Joy_ we’re turning every product on the internet into a potential moment of appreciation.
Our infrastructure stitches together live merchant feeds, AI-powered search and instant checkout rails so brands can offer any product online, in real time, through a single API.
That engine powers a new class of experiences:
* Commerce infrastructure for retailers – plug Joy_ into site-search or checkout to fill “out-of-stock” gaps, drop-ship on demand and grow assortment with zero inventory or new workflows.
* Gift cards that aren’t stuck in walled gardens – branded, media-rich and redeemable for millions of items instead of a single store.
* Loyalty & rewards that feel personal – users save for the exact product they want, not a generic catalogue.
* Employee benefits that people actually use – from monthly stipends to one-off “thank-yous”, all white-labelled and API-first.
Because everything is virtual we need no warehouses, no middlemen and zero extra stock; partners keep the margin while customers enjoy true flexibility.
Whether you’re an e-commerce giant filling assortment gaps, a fintech nudging action with meaningful rewards, or an HR platform boosting engagement, Joy_ is building the infrastructure for the future of commerce.
Tasks
As our second dedicated engineer on the client side, you will:
* Own the entire front-end experience—from design critique to pixel-perfect implementation—and contribute to the Python back-end when needed.
* Craft elegant, responsive UIs for customers (B2C gift card flows) and partners (B2B self-serve dashboards, embeddable widgets).
* Shape component libraries, design tokens, and accessibility guidelines in a company with focused product-management and design resources.
* Pair with founders on product discovery, run quick experiments, and measure impact.
* Review code and mentor future team-mates.
Requirements
What we're looking for
* 3+ years of professional experience building modern web products, with Vue knowledge (or React/Angular expertise with enthusiasm to learn Vue).
* Solid Python skills: comfortable adding endpoints, optimizing queries, and debugging async workers.
* Strong design sensibility—at ease discussing typography, layout grids, and motion; proficient with Figma.
* Pragmatic testing approach (unit + e2e) and dedication to performance and accessibility.
* Excellent spoken and written English.
Nice to have
* Experience with payments, e-commerce, or loyalty/rewards products.
* Familiarity with experiments/A-B testing frameworks and event analytics.
* Experience with design systems or Storybook, and infrastructure-as-code (Terraform, Pulumi).
* Working knowledge of SQL, RESTful API design, GitHub Actions (or similar), and containerized deployments on Kubernetes.
Benefits
How we work & what you get
* Small, senior team & big ownership – ship end-to-end features in days, not quarters.
* Hybrid-friendly – our office is in Berlin, with team members across Europe (regular in-person meetings).
* Competitive salary + meaningful equity – we want you to win with us.
* Purposeful product – build tech that makes giving (and getting) gifts more personal, sustainable, and joyful.
