Stellenbeschreibung

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.

Sounds like you?

Send a quick note, your GitHub or portfolio, and a short example of a UI you're proud of. No formal cover letter needed—just tell us _why Joy__ and how you can make an impact.

We can't wait to build the future of commerce together! 🎁

At Joy_, we place great value on equal opportunities. We believe that an outstanding work environment should reflect a diversity of backgrounds, talents, and thoughts. Together, we grow as a team based on our individual strengths. Every personnel decision is made solely based on qualifications, performance, and the requirements of the company.
