Job Description

Location/s: Seoul, South Korea
Recruiter contact: Shing Ying Low

We are looking for an experienced Senior / Principal Engineer – Energy & Technical Advisory to join our growing energy business in South Korea.
This is a senior technical and client-facing role, combining engineering, technical advisory and project leadership across renewable energy projects in Korea and the wider Asia-Pacific region.

The opportunity

You will provide technical leadership across renewable energy projects from feasibility and development through design, construction, commissioning and operation.

You will:

  • Lead feasibility studies, engineering assessments and design reviews.
  • Coordinate multidisciplinary inputs across civil, structural, geotechnical, electrical, mechanical and grid disciplines.
  • Lead or support Technical Due Diligence (TDD), Lenders’ Technical Advisory (LTA), Owner’s Engineer and Independent Technical Advisor assignments.
  • Identify and advise clients on technical, cost, programme, constructability and performance risks.
  • Review CAPEX/OPEX assumptions, EPC arrangements, major equipment, grid connection and O&M strategies.
  • Lead multidisciplinary assignments as Technical Lead or Project Manager.
  • Provide clear, commercially relevant technical advice to developers, investors, lenders and asset owners.
  • Support and mentor developing engineers within the team.

About you:


You will bring strong technical experience in renewable energy or power infrastructure, ideally across one or more of:

  • Offshore or onshore wind
  • Utility-scale solar PV
  • Battery Energy Storage Systems (BESS)
  • Grid connection, substations and transmission
  • Balance of Plant and associated civil/structural infrastructure

Ideally, you will have:

  • A relevant engineering degree.
  • Around 10+ years’ engineering experience, although the relevance and depth of your experience are more important.
  • Strong practical engineering and multidisciplinary coordination experience.
  • Experience across multiple stages of the renewable energy project lifecycle.
  • Strong technical judgement and client-facing capability.
  • Experience leading technical workstreams, projects or teams.
  • Experience in TDD, LTA, Owner’s Engineer or Independent Engineer assignments and professional registration such as CEng or PE would be advantageous.
  • Experience in the South Korean renewable energy market and the ability to work effectively with both Korean clients and international technical teams would be highly valued.
  • Fluent English language capability is needed.

What we’re looking for

Above all, we’re looking for someone who combines technical credibility, multidisciplinary thinking, commercial awareness and client confidence.
You do not need to tick every box. If you have strong renewable energy experience, genuine engineering depth and the ambition to take on broader technical leadership and advisory responsibilities, we’d like to hear from you.
