Stats Perform is looking for an experienced Backend Software Engineer to join the team behind Opta Search – a powerful, data-driven analytics product used by leading sports organizations across the globe. This role is key to the next stage of the product’s evolution, as we enhance its capabilities, scale to new sports and modernize the technology. You’ll focus on building and improving backend services primarily in Node.js, while also working with Python-based data pipelines that deliver insights from machine learning and computer vision models.
This is a hands-on, product-driven role in a fast-moving environment. You’ll be working closely with other engineers and a Prague-based Product Owner to deliver new features, integrate complex data sources and help create a seamless experience for both internal and external users.
 

Responsibilities:

• Build and maintain backend services in Node.js – performance, reliability and clean code.
• Support and integrate Python-based data pipelines (especially ML/computer vision feeds).
• Collaborate with frontend devs, POs and occasionally data engineers to deliver production-grade features.
• Extend, refactor and improve a platform that is currently used by top international sports leagues.
   

Requirements:

• Solid JavaScript backend experience.
• Comfort reading, debugging and lightly working with Python (ML/data feeds context).
• Experience with REST APIs, data modeling and general backend good practices.
• Able to work with semi-structured or messy data and transform it into usable APIs.
• Good communication – you’ll be working with a distributed team and a PO in Prague.

Nice to have:

• Experience in data-heavy environments, or even better, sports data.
• Familiarity with cloud environments (AWS, GCP, etc.).
• Understanding of ML/AI outputs and how they integrate into product features.
• Tech stacks like FastAPI, Kafka or async frameworks.

We offer: 

• Be part of a product that’s already live, loved and growing.
• Work on a modern, interactive platform with real-time sports data and visualizations.
• Help define and build the next-gen backend stack.
• Extra vacation days, with more added as your tenure grows.
• Mental health days – Company-wide days off to reset and recharge.
• Hybrid work flexibility – Because productivity isn’t tied to a desk.
• Career & learning support – Access to Udemy, O’Reilly, and other learning platforms to keep your skills sharp.
