Prediction market engine (upcoming) – real-time betting-style forecasting platform for internal and client use

We build long-term client partnerships. This is strongly evidenced by our 2026 client NPS of +50 and the fact that we retained all of our major clients.

Our current technologies
Open source platforms: PimCore, Magento, Shopware, WordPress
Backend: PHP, Symfony, MySQL, REST API, GraphQL
Frontend: Knockout.js, React, TypeScript, Vue.js, React Native
CI/CD tools: Git, Docker, Gitlab, Github, Ansible
Other: Kafka, Scala, Claude Code, AI vector databases, and other technologies for custom projects

What you will do (including prediction market work)
Build and maintain scalable eCommerce, PIM, and headless B2B ecosystems.

Design and implement a prediction market module – including order books, dynamic odds calculation, real‑time settlement, and user position tracking.

Integrate prediction market logic with Kafka streams for live event data (e.g., sports, financial, or internal forecasting).

Work with React/Vue frontends to display live probabilities, trade interfaces, and market history.

Optimise database queries and manage state across distributed systems.

What we look for
Strong experience with PHP/Symfony, MySQL, REST/GraphQL, and modern frontend frameworks (React or Vue).

Familiarity with Kafka (stream processing) and containerisation (Docker).

Understanding of real‑time systems, order matching, or exchange‑like logic – prediction market experience is a strong plus, but not mandatory if you learn fast.

High ownership, clean code, and passion for building user‑friendly features.
