Make the Unseen seen! Our goal is to reinvent scouting in football and build the #1 global scouting platform for identifying and developing talent. With the help of modern AI technology, CUJU enables every young football talent to be seen – regardless of origin, gender, or social background. We create fair opportunities and transparent pathways into professional sports. Our platform connects athletes, clubs, and organizations worldwide to rethink scouting – data‑driven, objective, and mobile.

Together, we are shaping the next generation of global talent scouting.

Your Mission:
As CUJU’s first Senior Data Engineer, you will build the data foundation of the company.

Your mission is to transform fragmented data across multiple systems into a reliable, scalable, and usable data layer that enables:

• Clear business metrics (e.g. MAU, retention)
• Product decision‑making
• Future player performance insights

You will play a critical role in shaping how data is structured, connected, and used across CUJU.

What You’ll Work On:

• Define and implement core data models (users, events, performance)
• Design and operate robust, production‑grade data pipelines
• Establish a single source of truth for key business and product metrics
• Structure data for business and product analysis (retention, funnels, activation)
• Build and deploy data services and jobs on AWS (e.g. S3, Lambda, ECS/EKS, Glue, Athena, Redshift, etc.).
• Make pragmatic decisions on how data is stored, processed, and accessed
• Evaluate and introduce tools (e.g. Big Query, Snowflake, Databricks) where they add clear value
• Ensure the architecture scales with product, AI, and data growth without over engineering
• Optimize pipelines for scalability, cost efficiency, and performance.
• Write clean, maintainable, and well‑structured Python code following software engineering best practices.
• Work closely with Product, Engineering, AI, and Business teams

What You Bring:

• 5-7+ years of professional experience in data‑heavy roles (data engineering, ML engineering, or similar).
• Strong programming skills in Python (clean architecture, testing, modular design not just scripts).
• Solid SQL skills and experience designing analytical schemas.
• Hands‑on experience building production data pipelines and services.
• Strong experience with AWS and cloud‑native data architectures.
• Familiarity with infrastructure concepts (CI/CD, monitoring, logging, deployments)
• Comfortable working with imperfect, real‑world data and evolving requirements.
• Experience working in fast‑paced or early‑stage environments
• You understand that data work is software engineering.
• Excellent communication skills in English, with the ability to effectively collaborate with cross‑functional and international teams.
• Passionate about sports, performance analytics, and leveraging data to make a real‑world impact.

• Opportunity to be the founding member of a strategic new Data team
• Purpose & impact – build something together that transforms the world of sports
• Significant influence on CUJU’s growth, product strategy, and industry‑leading innovation
• Work at the intersection of sports and technology – with international clubs, partners, athletes, or influencers
• Creative freedom & responsibility – actively shape processes, contribute your ideas, and make a real impact
• Short decision‑making paths – direct communication, quick decisions, and close collaboration with management
• Personal development – individual learning opportunities and room to grow beyond yourself
• Diverse benefits – e.g. 30‑day vacation, competitive compensation, corporate benefits, and more

• Build the technical foundation of CUJU’s data platform.
• Enable scalable, reliable, and production‑ready analytics across the company.
• Shape how data is ingested, processed, and used in products from day one.
• Directly influence player insights, product features, and long‑term data strategy.

We are looking for a passionate, communicative, and eager individual to shape the future of sports. If you are interested in this challenge, we welcome your application.
