We build the tech that moves industries forward. We have our eyes set on AI, energy, logistics, sports and other complex and exciting segments.
We believe in an innovative approach to solving deep issues and encourage our people to find their own solutions. We are constantly rethinking processes, business models, architecture, and tech stacks.
We foster a sense of curiosity, experimentation, and passion beyond code. With us, you can easily deepen your knowledge in any field you’re curious about. And because we work across many industries, you’ll be gaining the experience others can only dream of.
At the forefront of reimagining how industries operate, we are a team of builders and thinkers reshaping e-commerce, ticketing, and logistics from first principles. Our work is grounded in curiosity, experimentation, and a drive for real business impact. We eliminate inefficiencies—not just in code, but in legacy models and outdated assumptions. For those who seek to solve complex problems and mentor others in the process, this is a place to thrive.
We are looking for a Senior Data Engineer who combines deep technical expertise with a strategic mindset. In this role, you’ll architect and build intelligent data ecosystems that power autonomous workflows—integrating Generative and Agentic AI to help businesses move faster, think smarter, and operate more efficiently. Equal parts architect and builder, you’ll be instrumental in delivering high-impact, AI-powered solutions across diverse industries.
