Principal Infrastructure Engineer

Lead Highway & Drainage Design Projects in Hungerford

You're an experienced engineer who wants greater ownership, varied projects and the chance to shape how infrastructure design is delivered. In this Principal Infrastructure Engineer role, you'll step into a position where your expertise is genuinely valued, your ideas influence outcomes, and you will enjoy a clear pathway to further progression.

Joining a respected consultancy with a strong presence across Berkshire and the South, you'll be part of a supportive senior team known for high-quality engineering, pragmatic solutions and long-term client relationships. You'll work in a collaborative environment where autonomy is encouraged, and where your technical leadership will help guide the next generation of engineers.

As the Principal Infrastructure Engineer, you will be leading and delivering highway and drainage design projects across residential, commercial and mixed-use developments. You'll be overseeing feasibility, detailed design and technical approvals, and you'll provide technical assurance across design work. You'll coordinate with clients, local authorities and multidisciplinary teams, and you'll mentor junior engineers while ensuring designs meet all relevant standards.

To succeed as the Principal Infrastructure Engineer, you will have strong experience in UK development infrastructure design, including highways (S38/S278) and drainage (S104/S106) schemes. You will be confident using industry-standard software such as Civil 3D, MicroDrainage or similar, and you'll bring the ability to manage projects, engage with stakeholders and provide technical direction.

You will receive a salary of £53,000-£59,000, alongside a competitive benefits package including pension, professional development support, paid memberships and flexible working arrangements designed to help you balance life and work.

You'll be based in Hungerford, Berkshire, working on a hybrid basis with flexibility to suit both you and the project needs. Progression opportunities are clear and achievable, with routes into Associate and technical leadership roles as the team continues to grow.
