The opportunity

As a BESS System Architect, you are the technical authority for end-to-end Battery Energy Storage System architecture, spanning grid, electrical balance of plant, batteries, power conversion, automation, software, and services.

This is a non-managerial, but a pivotal role within the T&SD organization, critical to both execution excellence and future differentiation.

You ensure architectural coherence, technical robustness, and long-term scalability of GPQSS BESS solutions, supporting R&D projects, but as well providing expert support to CoC (tendering & execution), and to Technology and Product Management in roadmap definition.

The role requires strong system-level thinking, the ability to author architecture and system specification documents, and credibility to influence multidisciplinary teams without line authority.

How you'll make an impact

–    System Architecture & Technical Authority

•      Define, maintain, and evolve the end-to-end BESS system architecture from grid to cell, including EBoP, PCS, batteries, protection, automation, software, and services.

•      Act as architectural backbone for R&D projects, ensuring technical coherence during development and integration.

•      Own the system architecture framework, reference models, and design principles for GPQSS BESS solutions.

•      Author and maintain architecture and system specification documents aligned with GPQSS standards and comparable in depth and clarity to existing BESS architecture analyses.

–    System Requirements & Integration

•      Lead system-level requirement definition, ensuring traceability across disciplines and lifecycle phases.

•      Identify and manage cross-domain dependencies (electrical, mechanical, control, software, cybersecurity, services).

•      Support architectural trade-offs related to performance, safety, cost, scalability, and lifecycle value.

–    Tendering & Execution Support

•      Provide architectural guidance during tendering, feasibility studies, and pre-FEED activities.

•      Support execution teams by resolving complex system-level issues and integration challenges.

–    Technology Outlook & Differentiation

•      Contribute to future-looking technology roadmaps, including modularization, pre-engineering, standardization, and platform strategies.

•      Support competitor and market analysis from a system architecture perspective.

•      Enable differentiation through software-enabled value stacking and service-oriented architectures.

–    Collaboration & Influence

•      Act as a key technical interface toward Product Management, CoC, T&SD, suppliers, and partners.

•      Influence without line authority, enabling alignment across global, multicultural teams.

Your background

–    Master’s degree or PhD in Engineering, Power Systems, Control Engineering, or equivalent.

–    Minimum 10 years of experience in Battery Energy Storage Systems or closely related grid-scale energy systems.

–    Principle / Senior Principal Engineer level technical seniority and credibility.

–    Proven experience in defining complex system architectures and writing high-level architecture and system specification documents.

–    Deep understanding of BESS components: batteries, PCS, EBoP, protection, automation, EMS, SCADA, and digital services.

–    Solid knowledge of grid codes, grid-forming and grid-following concepts, and power system studies (RMS and EMT).

–    Experience working in multidisciplinary R&D environments and complex international projects.

–    Excellent communication skills, with the ability to explain complex concepts to diverse stakeholders.

–    Experience with modularization, pre-engineering, and scalable system design.

–    Exposure to lifecycle- and service-oriented BESS architectures.

–    Familiarity with competitor analysis, technology scouting, and roadmap definition.

–    Knowledge of international standards and certification processes (IEC, IEEE, UL).

–    Strategic mindset balancing short-term delivery needs with long-term innovation.
