Key Responsibilities

  • Product Commissioning (e-STORAGE products)
  • Lead product commissioning of e-STORAGE products across UK LTSA sites (SolBank, string inverters, MVSkids and associated MV plant) to OEM standard and project scope.
  • Own and set first power-on initialization parameters (OEM-trained personnel requirement per product manuals); incorrect settings risk equipment damage and certification non-compliance.
  • Own product commissioning standards, procedures, test records, and documentation packs; ensure consistency across all UK projects.
  • Provide product-level technical support to the site Cx team during energisation.
  • Support the site Cx team during SAT and witness testing; provide product-level technical sign-off.
  • HV/MV Operations & Safety
  • Competent for appointment to carry out MV/HV isolations, earthing, and safety document duties under the prevailing site safe system of work, as a mandatory precursor to intrusive PM/CM works. Site HV authorisation arrangements are defined per contract and phase (see MV/HV Authorisation & Control of Work).
  • Carry out operational HV/MV switching during the service phase, including switching for planned PM outages, CM interventions, and restoration on return to service, where CSE holds control of work under the contract.
  • Provide HV/MV support to the service team during PM and CM activities: isolations, earthing, switching, and safe access where service team work interfaces with HV/MV plant.
  • Lead HV/MV preventative maintenance across CSE, SMA and Power Electronics MV skids, RMUs, transformers, and protection systems per OEM schedules.
  • Lead corrective maintenance and fault investigation on HV/MV equipment: root cause analysis, rectification and return to service.
  • Provide safety leadership and oversight for all HV/MV activities in region, including supervision of third-party HV contractors where used.
  • Technical Expertise & Capability Building
  • Subject-matter expert across all inverter platforms (CSE string inverters, SMA, Power Electronics) for HV/MV maintenance activities; product commissioning expertise applies to e-STORAGE products.
  • Assess and develop service team competency for HV/MV support roles; deliver toolbox talks, training, and authorisation recommendations.
  • Feed field learnings back into standards, RAMS/SOPs, and OEM escalations.
  • Out of Scope
  • Routine non-HV/MV maintenance (LV PM, BESS enclosure servicing, HVAC, general CM). This is delivered by the regional service team, with this role providing HV oversight only where work interfaces with HV/MV plant.

Requirements

  • Trained and competent for MV/HV activities to 33kV; capable of appointment under company or client operational rules as contracts require.
  • Time-served electrical background with utility-scale BESS or solar commissioning experience.
  • Working knowledge of MV switchgear, transformers, and protection systems.
  • Familiarity with G99 requirements sufficient to support the site Cx team during compliance testing.
  • Full UK driving licence; regional and occasional national travel.
