Modelling Engineer - Defence Logistics

Contract | £550-£600 per day | Outside IR35 | Predominantly Remote

We are supporting a leading consultancy on a significant project within the defence logistics sector and are looking for experienced Digital Modellers to join the team.

This is an opportunity to work on a sensitive, technically complex programme focused on data science, operational analysis and quantitative modelling, with a particular emphasis on logistics and cost modelling.

The Role

We are looking for 1-3 experienced Digital Modellers who can work with a high degree of autonomy and contribute quickly to the development of analytical and modelling solutions.

You will be involved in areas such as:

  • Developing logistics and logistical flow models
  • Building cost models
  • Developing stock and flow models
  • Creating event-based / discrete-event logistical models
  • Applying quantitative analysis and data science to complex logistics problems
  • Translating real-world operational challenges into robust computational models
  • Working with stakeholders to understand requirements and communicate modelling outputs

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.
