Cutting-Edge Systems Integration Role – First of its Kind

An exciting opportunity has arisen to join High Speed Two Ltd (HS2) as a Functional Integration Engineer within the central Systems Integration team, part of the Chief Engineer’s organisation.

This is a genuinely unique systems integration role working client-side on one of Europe’s largest and most technically complex infrastructure programmes. The team is responsible for ensuring the future HS2 railway operates as a fully integrated system, coordinating how multiple engineering sub-systems interact operationally across the end-state railway.

The role sits within the Infrastructure Directorate, acting as the Prime Systems Integrator for HS2, responsible for integrating operational, technical and engineering requirements into a safe, efficient and operational railway.

Unlike traditional design engineering positions, this role focuses heavily on systems thinking, problem solving, interface management and operational integration across complex engineering environments.

You will support the functional integration of complex railway and operational systems including:

• Signalling & command/control systems
• Rolling stock systems
• SCADA & operational control systems
• Engineering management systems
• Stations, telecoms and infrastructure interfaces

Working within the wider systems integration framework, you will analyse how systems communicate, interact and function together operationally, helping define integrated technical solutions across the railway lifecycle from requirements and architecture through to testing, commissioning and operational readiness.

A key part of the role involves analysing operational scenarios and mapping interactions between systems, interfaces, users and operational processes to ensure the railway functions safely and effectively as a complete integrated system.

The team uses systems engineering, modelling and Enterprise Architecture methodologies to manage functionality, interfaces and information flows across the programme.

The team is open to candidates from both rail and non-rail sectors including:
Defence, Nuclear, Aviation, Complex infrastructure & Software or hardware systems environments

Rail systems experience is preferred, but transferable experience from other highly regulated, safety-critical or operational environments is strongly welcomed.

This role would suit someone who enjoys solving complex engineering problems, influencing stakeholders and working across multidisciplinary technical environments.

Practical delivery experience is more important than specific software tool expertise. HS2 is looking for engineers who have helped deliver integrated systems, products or software through design into operation, service or live environments.
