Senior Software Engineer, Modelling: Kallikor Engineering London Kallikor London Kallikor

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.

We are seeking a Senior 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. This role is open to candidates from a wide range of technical backgrounds who have a passion for problem-solving and a desire to work in a collaborative and supportive environment.

• Developing and implementing algorithms which result in plausible modelling behaviour
• Building pipelines to extract, synthesise and integrate data from various sources, making it available to simulation engines and user interfaces
• Building tooling that enables model developers to do their work quicker and better
• Profiling and improving the performance of models so that we can reach new levels of speed and scale
• Working cross-functionally across Kallikor to support adjacent projects where required
• Write high-quality, well-tested code following modern engineering practices and design patterns
• Create efficient, maintainable code that transforms prototype models into production-ready solutions

Why you’re made for this:

• Strong software engineering fundamentals including system architecture, design patterns, and development best practices
• Advanced Python programming skills with experience building complex, maintainable systems
• Professional software development experience with a track record of delivering high-quality, production-grade code
• Experience with scientific computing libraries such as NumPy, Pandas, or SciPy in production environments
• Holistic software development mindset covering testing, documentation, security, and performance
• Track record of mentoring other engineers and sharing knowledge across teams
• Working knowledge of mathematical modelling concepts (systems dynamics, event-based modelling, agent-based modelling) and how they translate to code
• Experience working with simulation systems or digital twin technologies
• Software optimization expertise with a focus on improving performance in computationally intensive applications

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.
