The Project Manager is responsible for the integrated delivery and commercial performance of civil engineering projects across Peritas' portfolio.
Operating at a mid-level within the Trailblazer tier, this role applies structured project management discipline that is grounded in PMBOK principles, alongside strong commercial acumen to plan, execute, monitor, and close projects in a way that is technically excellent, financially sound, and commercially astute.
This role sits at the intersection of internal delivery, external client engagement, and commercial management.
You will work closely with technical leads, design staff, subconsultants, and clients to ensure projects are delivered within scope, on programme, within budget, and at the margins that sustain Peritas' growth.

Identify and prepare variation claims in a timely manner; substantiate claims with clear programme and cost evidence
