The Company
One of the top global BESS players, having deployed over 20 GWh of energy storage across the Americas, Europe, Asia, and Australia. Known for its cutting-edge technology, the company delivers highly modular systems powered by a proprietary AI-driven EMS, supported by a vertically integrated model that includes in-house manufacturing of PCS, battery modules, and packs.

Recently listed on the stock market following a strong track record of global growth, the company is financially robust and continuing to expand its presence across the US. Joining at this stage offers significant exposure to a growing North American organization, major utility-scale projects, and strong opportunities for long-term career progression. The culture is fast-moving and meritocratic, with a technically experienced leadership team and significant investment behind its US expansion.

The Role
Support the development of competitive utility-scale BESS solutions across the Americas, acting as a technical partner to customers, EPCs, developers, and the commercial team throughout the pre-NTP phase.
This position will take technical ownership from initial customer engagement and RFP review through solution development, proposal preparation, compliance review, and handover into project execution.

Key Responsibilities:
  • Review utility-scale BESS RFPs, specifications, technical requirements, and customer documentation to define appropriate system solutions.
  • Develop technical proposals, system designs, layouts, drawings, and supporting documentation based on project and customer requirements.
  • Work directly with customers, developers, EPCs, and engineering teams to answer technical questions and support the development of competitive solutions.
  • Provide technical guidance across BESS system integration, including batteries, PCS, controls, communications, thermal management, fire protection, and system layout.
  • Coordinate with Product and R&D teams around customer feedback, certifications, product enhancements, and cost-performance improvements.
  • Support technical presentations, customer meetings, and industry events alongside the commercial team.
  • Ensure a clear technical handover from the pre-sales phase into project execution following NTP.

The Candidate
  • 3+ years of experience within renewable energy, power systems, or a related technical environment.
  • At least 2 years of direct utility-scale BESS experience is strongly preferred.
  • Experience within Applications Engineering, Solutions Engineering, Systems Engineering, Project Engineering, or a similar technical position.
  • Strong understanding of utility-scale battery systems, PCS/inverters, controls, system layouts, thermal management, and fire protection.
  • Experience reviewing technical specifications, customer requirements, RFPs, or engineering documentation.
  • Bachelor’s degree in Electrical Engineering or a related engineering discipline.
  • Strong customer-facing communication and technical presentation skills.
  • Mandarin language capability is highly desirable due to regular interaction with engineering and product teams based in China.
