Ramboll defence and polar sectors hire: infrastructure strategy notes for engineers
Reviewed by Tom Sullivan

First reported on The Construction Index
30 Second Briefing
Ramboll has appointed former Royal Engineer Darren Carlile as head of growth and sales for buildings, targeting defence, national security, government, research and polar sectors. Carlile previously spent nine years at Aecom leading its defence and national security sector, where he positioned the firm as a Tier 1 multidisciplinary engineering services provider to the UK Ministry of Defence, Foreign Office, global defence OEMs and US visiting forces in the UK. The move aligns Ramboll with the UK’s recent strategic defence review and an upcoming ten‑year defence investment plan, signalling more complex secure and extreme‑environment infrastructure programmes.
Technical Brief
- Appointment is explicitly framed around defence and polar infrastructure as “increasing strategic importance” for Ramboll’s buildings unit.
- Role scope spans national security, government, research and polar sectors, indicating cross-portfolio coordination of complex facilities.
- Carlile brings 24 years’ Royal Engineer experience, implying strong background in expeditionary, hardened and remote-site construction.
- Nine-year tenure leading Aecom’s defence and national security sector gives direct Tier 1 MOD delivery experience.
- Previous remit included UK Ministry of Defence, Foreign Office, global defence OEMs and US visiting forces in the UK.
- Position is timed between the UK strategic defence review and a forthcoming ten‑year defence investment plan.
Our Take
Ramboll’s appointment in the UK defence and polar space comes as its engineers are also pushing into grid-stabilising technology for renewables, suggesting the firm is positioning itself for defence estates that must cope with higher on-site generation and fragile remote grids.
Aecom’s repeated appearance in recent UK infrastructure items in our database – from the STEP fusion prototype JV backing to regional road schemes – means Darren Carlile’s move into a Ramboll defence leadership role will put him up against a competitor with deep UK public-sector frameworks and programme controls capability.
With the UK Ministry of Defence and US visiting forces both cited, and a ten‑year defence investment horizon flagged, this role is likely to intersect with long-run estate resilience and climate-adaptation work, an area where cross-over with Foreign Office polar interests could pull in more Arctic/Antarctic infrastructure and logistics projects than typical defence appointments.
