About ZZAZZ

ZZAZZ is building the foundation for the future of the information economy. We believe that digital content deserves more than arbitrary monetization models and opaque metrics. By assigning transparent, real-time value to the world’s data and insights, we empower

everyone—from the casual user who sees the price and understands its worth to creators, consumers, advertisers, and businesses—to engage in a more equitable and meaningful exchange.

Our mission centers on trust, innovation, and inclusivity. We bring together a diverse team of thinkers, builders, and problem-solvers passionate about shaping a fairer digital marketplace—one that respects the complexity and worth of information and the people who produce it.

  • Experience designing micro-frontend architectures, with module federation or Single-SPA.

  • Proven ability to integrate frontend apps with RESTful APIs, WebSocket-based real-time data systems, and backend services.

Preferred Qualifications (Nice-to-Have)

  • Experience in optimizing frontend applications for high-frequency, data-intensive platforms (dynamic pricing, real-time bidding, ad-serving platforms).

  • Prior involvement in creating frontend solutions for payment gateways or advertising monetization platforms (Stripe integrations, Google Ad Manager, real-time transaction handling).
