Principal Software Engineer; Systems Architecture & Scalability

At Kallikor, we’re redefining the future of supply chains and automation by building immersive, world-scale synthetic environments. Leveraging the latest in AI, gaming, and open-source technologies, we empower businesses to continuously optimise, plan, and respond dynamically by providing a digital representation of their entire operations. Through advanced digital twins and enterprise metaverses, our platform allows companies to visualise, analyse, explore, and experiment with their supply chain environments, enabling smarter, faster decisions that drive real-world impact.

At Kallikor, you’ll work alongside individuals who strive for excellence in all they do and are driven to uplift and challenge those around them. We’re motivated by solving complex problems, aiming to achieve transformative change in the industrial landscape. Our roots lie in cutting-edge technology and strategic innovation, originally developed for the gaming, entertainment, and defence sectors. Learn more about our mission .

We are seeking a Principal Software Engineer to join our friendly, relaxed and inclusive team. You’ll be developing and implementing models and simulations used in our digital twins. Our models typically encode real-life systems and behaviours, allowing users to analyse performance and test different scenarios. Kallikor is moving from a single product to a diverse portfolio, including Warehouse Lab, Transport Lab, and Flow Lab.

To do this, we need to evolve our architecture from a unified core into a decoupled, modular ecosystem. We are looking for a Principal Engineer who can manage technical entropy and ensure our codebases remain agile as we scale.

• Decouple for Speed: You will lean into the architecture and APIs that currently couple our teams, getting hands‑on to decouple them so our squads can ship independently.

• Establish Enduring Patterns: You won't just fix bugs; you will create the architectural patterns that endure over the next two years of growth.

• Navigate the Big Rocks: You identify the massive technical hurdles that block multiple projects and solve them by doing, not just documenting.

• Technical Standards: You will uphold and establish engineering standards across the organization, ensuring software is built correctly from the start.

• Commercial Judgement: You balance sound technical choices with a commercial view of "what matters now".

• Trusted Peer: You are respected by L1–L3 engineers because you show the way through high-quality, production-ready code.

• Cultural North Star: You constantly think what's worth doing for customer impact, and can communicate and influence to follow you.

While we think the above experience could be important, we’re keen to hear from people that believe they have valuable experience to bring to the role. If you identify with the team and mission, but not all of our requirements, then please still apply.

Kallikor is determined to foster an environment where people can do their best work and feel like they belong. We believe a healthy culture, strong values and contribution from a diverse range of individuals will help us to achieve success.
