Principal Systems Engineer

Job Description

The Role - Overview

This role is for a Principal Systems Engineer, capable of technically leading and assisting the System Engineering tasks on the various Project Delivery System Engineering (PDSE) projects. The Principal System Engineer will play a lead role in one or more of Customer Requirements Management, the definition of the System and Sub-system Design, and subsequent production of detailed Product Requirements for Development Teams to implement, or be a technical leader in the integration, verification or validation of those systems.

The jobholder will be capable of building and maintain strong communication links with Global R&D, the Delivery Teams and the client (where necessary), and will be capable of interpreting and influencing their delivery strategy, and where necessary proposing new delivery strategies, based on the needs of these stakeholders. Principal System Engineers will be expected to advise on competing technical solutions, prioritise technical options and ultimately decide on the most optimal technical solution taking account of any technical and project constraints known at the time. Principal System Engineers are expected to fully engage with their stakeholder population during all appropriate phases of the SE lifecycle.

Success in the role will be measured primarily by the on-time within budget delivery of allocated tasks as agreed with the Systems Engineering Team Lead/Manager. Principal System Engineers will be expected to plan their own work within their overall agreed targets and advise in the capture of metrics.

This role will help play a major part in delivering the signaling and control systems necessary as the business demands. The role will focus on the front or early part of the lifecycle activities of the System Engineering process for most projects.
