The posting

Job Description

Purpose

Turn disparate project and financial data into clear, proactive insight - linking trends, early warnings, and predictive signals to decisions made by senior stakeholders and the leadership team. You’ll work with and around existing reporting requirements, adding analysis that explains the “why” and “what next,” not just the “what.”

Key Outcomes

  • Early warning: Detect leading indicators of cost/schedule variance, risk exposure, and delivery slippage before they surface in monthly reporting.
  • Predictive view: Build light‑weight forecasts and scenarios that quantify impact and recommend mitigations.
  • Decision support: Deliver concise, executive‑ready narratives (one‑pagers, briefings) that drive action.

What You’ll Do

  • Analyse large, multi‑source datasets (cost, schedule, risk, change, progress) to uncover trends, drivers, and anomalies.
  • Perform time‑series, regression, variance and sensitivity analyses; translate results into clear recommendations.
  • Create fit‑for‑purpose visuals (e.g., small-multiple charts, run‑charts, control charts) to evidence findings - no “dashboard factory.”
  • Define and track leading KPIs and thresholds; set up alerts and watchlists for emerging risks.
  • Partner with PMO/Project Controls/Finance to align insights with the reporting cycle and governance forums.
  • Improve data quality and consistency; shape simple data models that make recurring analysis faster.

Flexible working: We welcome you to ask about the flexibility you need. This might be part-time, remote working, or compressed hours for example. Anyone who applies for a role can ask about flexibility at interview. In return, we will explore what is possible for the role.

The Ideal Candidate

What You’ll Bring

  • Strong analytical toolkit: advanced Excel (modelling, Power Query, complex formulas), sound statistics, and storytelling with data.
  • Working knowledge of Power BI for light modelling/visuals (deep dashboard development not required).
  • Ability to join the dots across data, context, and delivery realities; crisp written and verbal communication for senior audiences.
  • Experience operating in fast‑paced project environments and influencing through evidence.

Nice to Have (Desirable, not essential)

  • Project Controls background (EV, cost & schedule analytics, trends, PMB, WBS) and/or Finance (budgeting, forecasting, variance).
  • Ability to interpret Primavera P6 outputs (logic, slippage, float) and link schedule signals to cost/risk.
  • Exposure to major infrastructure programmes.
  • SQL and/or basic Python/R for heavier analysis or repeatable workflows
  • Demonstrable experience in the development of reports and dashboards to a diverse set of stakeholders in a fast paced environmen
  • Highly skilled in mainstream BI tools (including but not limited to Power BI
  • Understand and promote data qualit
  • Knowledge or experience with Extract Transform Load (ETL
  • Knowledge with Azure integration services

The Skanska | Costain | STRABAG (SCS JV) is delivering the HS2 London Tunnels Contract. Scope of works includes twin-bored tunnels (TBM), SCL tunnels, shaft sinking, bridge demolition and reconstruction, services diversions, earthworks and the construction of site compounds.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
