 Nature and Scope

  • Assist in the commissioning and that associated quality assurance system is followed throughout the process of delivering the network capital programme.  From the early broad design review to detailed design checks at the later stages, equipment is checked, tested, safely energised and records updated as part of the process. The role is one of teamwork with many other specialists and colleagues.
  • Commissioning equipment requires communication and understanding with technical staff Contractors, Suppliers, and Customers as well as internally with designers and project managers.  Technical problems that occur on site are normally handled locally where the job holder will find a way to achieve the end often without reference to higher authority.
  • Using sound engineering judgement and applying precedents the job holder will make decisions about a way forward.  Often there is no right answer.  For this reason communication must be enthusiastic and unambiguous. Managing risk is often reduced by an ability to understand and rationalise conflicting points of view to reach an optimum solution.
  • Work is undertaken over a wide range of locations with varying degrees of accommodation. These include pre-construction design checking, design review meetings remote from support, site based office locations, indoor and outdoor construction locations.
  • Work often has to take place outside normal hours in order to lower the risk of customer interruptions whilst new plant is commissioned and tested.  The planning process towards this can be very long term.
  • Technical supervision is provided to this job holder including general remote managerial supervision.
  • Commissioning team’s input is vital to the project thought the lifecycle. As a result of network outage risk, customer requirements and the demands of the programme a high degree of flexibility to working times may be required and some work is completed outside normal hours.  The job holder will be a major influence on prioritisation and planning of work.
  • It is anticipated that with time, experience, operational training and further supported studies the post holder will become a Commissioning and Protection Engineer/SAP on the Primary and Grid network. Therefore candidates must be willing to push themselves to broaden their knowledge, embrace change, become to HNC or equivalent standard and have a positive attitude.


  • The job holder is required to communicate enthusiastically in an open and unambiguous manner.
  • The job holder will be assisting site based teams technically using interpersonal skills rather than positional power. In this role the job holder must be able to demonstrate the ability to understand and rationalise conflicting points of view to reach an optimum solution.
  • The post holder should possess the ability to make links and comparisons between situations within technical engineering that are not obviously related and to identify key issues in complex data.  The post holder is expected to use creative and lateral thinking to come up with new ideas or ways of doing things.
  • The post holder should be able to think and act ahead of time to take advantage of opportunities and to address problems.
  • Ability to build good working relationships within a team and with other staff within the business. The post holder is expected to communicate effectively with other members within the Network Operations team and build strong working relationships with other teams across the Business.
  • Enthusiastic & strong customer focus, without losing sight of safety and security of supply.
  • Ability to plan, co-ordinate and implement network re-arrangements/switching, under pressure, where customer supplies are affected.
  • He or she must have proven integrity and demonstrate a co-operative and team based approach to achieving overall business objectives.
  • Be able to demonstrate they are practical and results oriented by virtue of their actions, in the form of leading others to action by planning, motivating, organising and controlling tasks and deliverables in a complex fast-moving environment of regulatory change.
  • Be highly focused on delivering complex customer and operationally driven projects


Depending on experience, should you not currently possess the full range of essential skills, qualifications and competencies listed above, there may be an opportunity for further training to equip the successful candidate appropriately.  If the successful candidate does not possess all relevant competencies for the core grade, it will be appropriate to appoint at a lower grade until they have developed the required competencies.


Health & Safety Responsibilities

Managers and supervisors carry both legal and company responsibilities for ensuring the health and safety of their employees, those under their control, and those who might be affected by the work undertaken, i.e. public, visitors and employees of other organisations.  This includes briefing individuals working for them and ensuring there is the necessary understanding, competence and application of requirements to work safely and without harming the environment.


Employees are responsible for ensuring they fully understand the health and safety risks involved in their work activities and their responsibility to apply the controls needed to manage those risks to acceptable levels. Similarly where work activities can have an adverse impact upon the environment, and particularly where there are legal requirements, employees are responsible for understanding those impacts and the controls they must ensure are applied.
