Audit Technical Assurance Across One of Europe's Largest Infrastructure Programmes

Are you an experienced auditor or engineering professional who understands how technical work should be checked, verified and evidenced?

Would you like to apply your audit skills across major infrastructure contracts, ensuring that contractors follow the correct technical assurance processes and can demonstrate that their engineering work meets the required standards?

High Speed Two Ltd is recruiting two Technical Assurance Auditors to join its specialist team, with one position based in London and one in Birmingham.

Working across HS2's 19 major delivery contracts, you will plan and conduct Technical Assurance Reviews of Tier 1 contractors, assess whether the correct processes are being followed and ensure findings are recorded, reported and resolved.

This is an opportunity to work across one of the UK's most significant infrastructure programmes, influencing how technical assurance is applied consistently across civils, stations and Rail Systems.

HS2 operates a self assurance model, meaning contractors are responsible for assuring their own engineering work. Your role is to check that their assurance processes are appropriate, consistently applied and supported by the evidence needed to demonstrate compliance.

This is specifically a technical assurance auditing role, rather than a traditional Quality Assurance position. You will focus on whether the right technical checks are being carried out, whether requirements and standards are being applied correctly, and whether the evidence supports the conclusions reached.

You will manage the review process from planning and preparation through to reporting and closeout of corrective actions. You will also analyse findings and performance data to identify recurring issues, target future reviews according to risk and feed lessons back into HS2's technical processes.

The role offers broad exposure across multiple contracts and engineering disciplines, working with contractors, technical specialists and HS2 process owners.

• Plan and manage the Technical Assurance Review programme across allocated contracts and Integrated Project Teams.
• Prepare review documentation, audit files and question sets, and coordinate reviews with contractors and HS2 attendees.
• Chair Technical Assurance Reviews, record observations and Corrective Action Requests, and produce clear findings reports.
• Track corrective actions through to closure and monitor contractor performance against technical assurance requirements.
• Ensure review processes and question sets are applied consistently across different contracts and disciplines.
• Analyse review results and performance data, identifying trends, recurring issues and areas requiring further attention.
• Target review activity using a risk based approach, focusing effort where assurance concerns or delivery risks are greatest.
• Provide feedback to technical process owners and support improvements to HS2 assurance procedures.
• Work collaboratively with teams covering requirements, configuration and change management, risk, BIM and project management.
• Communicate findings clearly, challenge poor practice constructively and help ensure corrective actions are…
