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 also 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, cyber security, 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.
