About

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. Learn more at kallikor.ai.
Your Opportunity
You will be a key player in shaping the future of both your and the wider Engineering teams.
Lead and shape the future of our solution team consisting of backend engineers, working closely with our Product, Modelling and DevOps teams.
Drive our technical direction in the solution space - we have a strong technical foundation, but we are always looking to innovate further and push boundaries.
Mentor and grow the team - with a strong focus on coaching and developing our talented junior engineers.
Handle interdependencies with our other teams.
Effectively balance the creative exploration of a consumer-facing experience with the need to maintain our delivery commitments.
Work with Engineers that are using Node.js and Python
Why you’re made for this
You’re passionate about technology and how it can help deliver a great product. We use mainly Python and expect all our engineers to have strong Python proficiency.
Prior experience with FastAPI and Postgres. Other technologies including cloud (AWS), Docker, Kubernetes and Celery would be beneficial.
You thrive on the inherent ambiguity of an early stage business. You can navigate the frequent changes and see the opportunity of learning and adapting our technology as we go along.
You’re experienced with coaching and mentoring a team - you don’t want to stop being hands-on but you also enjoy other activities (whether it’s pairing and teaching a more junior member or sitting with your product team to figure out where we’re heading in the next 3 months).
You prioritise quick delivery: foundations are important and we’re all in when it comes to doing this right, especially when it has a lasting impact. However, the biggest risk to us is building the wrong stuff rather than building the stuff wrong. We prefer to ship quickly and learn quickly.
You love working as part of a close-knit group. We’re a highly collaborative team and often work together to solve complex problems and learn new skills. You proactively reach out to the wider team when there’s need for input and encourage others to do so as well.
About Us 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.
