About the job:
Ethos Engineering requires the services of an Electrical Engineer to support energy infrastructure projects, including substations, landing stations, interconnectors and associated facilities. We are seeking a Senior Electrical Engineer with a strong electrical building services background to lead the design and delivery of electrical systems for these specialist buildings.

The role is focused on the electrical services within energy infrastructure environments, rather than primary HV equipment design. You will take responsibility for delivering robust, compliant and buildable electrical designs for operational buildings located within complex power installations, working closely with HV specialists, clients and multidisciplinary teams.

This role is primarily office-based, with regular site and client interface primarily in Ireland and the UK.

Key Responsibilities

• Lead the electrical building services design for energy infrastructure projects, including:

  • Control buildings

  • Relay rooms

  • Converter / landing station buildings

  • Ancillary and operational facilities within substation sites

  • Standby and emergency power systems (diesel generators)

  • UPS systems and associated LV and DC distribution

  • Small power and general power distribution

  • Internal and external lighting systems

  • Fire alarm systems

  • Electronic security systems (access control, CCTV, intrusion detection)
    

• Develop DC power distribution designs for control and protection systems within substations and landing stations.
  

• Design electrical containment systems, including:

  • Cable ladder, tray and trunking systems

  • Containment coordination for MV switchgear communication, protection and control cabling

  • Integration of LV, ELV and control cabling within congested plant environments
    

• Prepare electrical layouts, schematics, single-line diagrams and technical specifications for building services systems.
  

• Develop earthing and lightning protection strategies for buildings located within substation and high-risk electrical environments, coordinating with wider site earthing systems.
  

• Interface closely with HV/MV engineers to ensure building services designs are fully aligned with:

  • Substation operational requirements

  • Protection and control philosophies

  • Client and network operator standards
    

• Review contractor submissions, technical queries and as-built documentation.

• Support site inspections, installation reviews and commissioning activities as required.

• Mentor junior engineers and contribute to the development of energy infrastructure building services capability within Ethos Engineering.

Experience & Qualifications

• Honours Degree in Electrical Engineering or equivalent.
  

• Typically 8+ years’ experience in electrical building services design, ideally within:

  • Energy infrastructure

  • Industrial facilities

  • Data centres

  • Mission-critical or utility-adjacent environments
    

• Demonstrable experience designing:

  • Generator and UPS systems

  • LV and MV Protection Schemes

  • Small power and lighting

  • Fire alarm and electronic security systems

  • Electrical containment and coordination in complex plant environments
    

• Experience with substation, landing station, interconnector or converter station buildings is highly desirable.

• Familiarity with DC systems for control, protection or auxiliary power distribution is an advantage.

• Chartered Engineer status (or working towards) is desirable but not essential.

Technical Skills & Knowledge

• Strong grounding in electrical building services design principles and best practice.

• Understanding of electrical systems within high-risk or operational power environments.

• Knowledge of relevant standards, including:

  • ETCI / IS standards

  • BS and IEC standards

  • EN standards

  • CIBSE guidance (where applicable)

• Proficiency in tools such as:

  • AutoCAD

  • Amtech / Trimble (or equivalent)

  • ETAP (desirable)

  • Dialux

  • Revit (desirable)

• Strong technical writing and documentation skills.
