About the role
- Own and build core optimisation systems: Design, implement, and operate ML and optimisation models that power pricing, matching, and allocation within Rosso and related systems, from research through to production.
- Solve complex applied problems: Develop linear programming and optimisation solutions for batch and near–real-time use cases, balancing cost, risk, portfolio constraints, and commercial outcomes.
- Ship production-grade models: Build and maintain end-to-end ML and optimisation pipelines in the cloud (AWS preferred), ensuring robustness, explainability, and operational reliability.
- Develop core IP in-house: Replace third-party logic with high-quality internal implementations, iterating quickly as product and market understanding evolves.
- Collaborate and influence: Work closely with product, engineering, and commercial teams to translate business needs into effective technical solutions, communicating clearly with non-technical stakeholders.
- Raise engineering standards: Contribute to best practices in modelling, experimentation, and code quality, and provide informal mentorship to junior engineers and data scientists.
Requirements
- Strong optimisation background: experience with linear programming, operations research, or constrained optimisation in real-world systems.
- Hands-on ML / data science experience: proven ability to build and ship models that matter.
- Production mindset: experience designing, deploying, and maintaining cloud-based ML or optimisation systems.
- First-principles thinking: comfortable working in ambiguous, greenfield problem spaces.
- Strong Python skills and experience with the standard data science stack.
- Commercial awareness: understands how technical decisions translate into business impact.
