- Project & Team Delivery: Experience managing multiple projects and coordinating workload, resources, and deliverables across a multidisciplinary team.
- Client Relationship & Business Development: Ability to manage client relationships, provide advice, support new work opportunities, and contribute to fee estimates and bid writing.
- Digital Design & Coordination: Competence in AutoCAD, Autodesk Revit MEP, IES, NBS, and Microsoft packages. Further training can be provided where required.
- Mentoring & Leadership: Ability to support, guide, and manage junior to intermediate engineers, with potential line management responsibility.
