- Experience writing efficient, scalable Python code beyond basic scripting.
- Strong Experience with Monte Carlo simulation, stochastic modelling, or advanced statistical modelling.
- Good statistical judgement and ability to assess model outputs.
- Experience developing algorithms, simulations, or analytical frameworks.
- Exposure to AWS or similar cloud environments.
- Strong stakeholder communication skills across technical and non-technical teams.
