Job description

Operational analysis is the discipline of answering hard questions with evidence when the decision cannot wait for perfect data. This is a junior post inside that team: you would do the collection, the collation and the analysis, and present it back in a form that stands up to scrutiny.

It suits someone early in their analytical career who is genuinely comfortable with a messy data set and unbothered by working to a deadline — the output here is often needed for a decision the same week.

What you would be doing

• Undertake data and operational analysis on complex problems, often with large data sets and simple tools.
• Apply operational analysis techniques — modelling, what-if analysis and wargaming among them.
• Collect, collate and analyse data across a range of sources and tools, including Python and advanced spreadsheet work.
• Present findings concisely and logically, so the method is as visible as the answer.
• Produce verified, validated and consistent data sets under time pressure.
• Summarise results into dashboards, presentations and written reports.
• Support the team in developing and updating documentation and reports.

What you would bring

• Recent experience conducting analysis that fed a real decision.
• Ability to review and analyse large data sets with commercial and in-house tools.
• Working Python, expert-level spreadsheet skills, and confidence with dashboard tooling.
• A methodical habit — verified data, stated assumptions, reproducible steps.
• Clear written and spoken English.

The work is full time on site in The Hague.
