We are actionable insights builders.

At Colours we understand the specific challenges businesses are facing. We leverage best-in-class industry expertise, tools and proven strategies to build custom-made solutions.

Your mission is🎯

To scale projects for our clients and design innovative solutions. Your role will also be crucial in driving our internal "AI-first" mindset, ensuring we actively apply cutting-edge technologies. You’ll help us transition into a future where delivery is driven by AI, while the foundations remain built on solid data engineering.

Designing robust and scalable orchestration platforms, testing, and securely operating advanced generative models in our clients' production environments.
Analyzing data using ML and advanced analytics to uncover key insights and business contexts.
Providing expert consulting and tailoring training programs to meet specific client needs.

Right now, we have several active projects across the Czech, UK, and US markets, spanning industries from retail and telco to insurance (e.g., O2, Rohlík, Financial Times, Škoda Auto, Partners Banka, or Marks & Spencer). For these clients, we are transforming their core business models from manual to AI-driven.

This is the future of business, and as our new leader, you will have the opportunity to spearhead these projects. You will have a direct, significant impact on how these companies operate.
