Product Designer in London

At Kallikor, we’re shaping the next generation of supply chain decision intelligence through simulation digital twins. We build powerful digital representations of real-world operations that help organisations plan, optimise, and adapt continuously in the face of complexity and change. By combining advances in AI, simulation, and open-source technologies, our platform enables businesses to visualise, analyse, and experiment within living digital twins of their end-to-end operations. These environments allow teams to explore scenarios, test decisions, and respond dynamically, unlocking faster, smarter outcomes with real-world impact.

You’ll join a team of deeply curious, driven individuals who care about technical excellence and meaningful progress. We’re motivated by hard problems and ambitious goals, and we challenge one another to raise the bar every day. Our foundations are rooted in pioneering technologies originally developed across gaming and defence, now applied to some of the most complex industrial systems in the world. Kallikor operates with a clear mission and identity, focused on transforming how global supply chains are understood and managed.
