We’re working with a fast-growing technology company looking to hire a Senior Data Scientist (Operational Research) to help solve complex, large-scale optimisation problems within its operational network.
This is a senior individual contributor role sitting at the intersection of Operational Research and Data Science. You’ll develop optimisation models and algorithms that directly influence real-world decisions across areas such as scheduling, assignment, pricing, and network optimisation.
What you'll be doing
- Designing and developing large-scale optimisation models and algorithms
- Solving complex scheduling, assignment, and network optimisation problems
- Applying mathematical programming, heuristics, and metaheuristics to real-world challenges
- Building, testing, and benchmarking optimisation solutions using Python
- Taking optimisation models from initial concept through to production
- Working closely with Data Scientists, Software Engineers, and commercial stakeholders
- Improving the scalability and performance of existing optimisation systems
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
