Principal Adoptions Engineer

Join to apply for the Principal Adoptions Engineer role at West Northamptonshire Council
.

We are seeking an experienced and motivated Principal Highways Engineer to join our Highways Development Management team at West Northamptonshire Council. This senior role leads on the assessment, negotiation, and delivery of highway works linked to new developments, focusing on Section 38 and Section 278 agreements, design reviews, and the adoption of new infrastructure into the public highway network.

Knowledge of the planning process is highly beneficial, as there may be a need to assist colleagues in responding to planning applications from a highways perspective. This could include reviewing transport assessments, travel plans, and layout designs, providing technical advice, and working with developers to secure suitable mitigation and infrastructure improvements.

You will take highway agreements through the full lifecycle — from pre-application advice and technical review of designs, through to approval, construction oversight, inspection, and final adoption. This will involve scrutinising detailed submissions to ensure they meet required standards, protecting the council’s interests and ensuring long‑term maintainable assets for the public.

As a senior member of the team, you will also provide expert technical advice on complex or high‑profile schemes, lead negotiations with developers and consultants, and mentor junior engineers. Collaboration across planning, legal, and highways colleagues will be central to your success in ensuring that growth in West Northamptonshire delivers safe, high‑quality, and sustainable highway infrastructure.
