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 youll 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.
