Fluence

Role Overview

The Data Center BESS Principal Engineer is a senior-level technical role focused on supporting Global DC Sales and serving as a key individual contributor within the Sales Engineering organization. This role leads end-to-end technical strategy and solution development for data center energy infrastructure opportunities, from concept through contracting and execution. The Engineer also serves as a thought leader in external engagements with industry advocacy and rule‑setting bodies.

Key Responsibilities

• Lead end-to-end technical strategy and solution development for data center energy infrastructure opportunities from concept through contracting and execution.
• Architect scalable system solutions aligned to customer requirements, utility constraints, and Fluence product roadmap.
• Own grid studies, modeling, and technical evaluations supporting interconnection, contracting, and solution validation.
• Serve as the primary technical interface across customers, utilities, regulators, EPCs, and OEMs to resolve risks and drive alignment.
• Coordinate cross‑functional teams (Sales Engineering, GID, Modeling, Product, Execution) to define requirements and ensure successful delivery.
• Ensure continuity of technical intent through execution, commissioning, and onsite validation.

Advanced Grid‑Forming (GFM) Projects

• Keep abreast of lessons learned from technical execution of advanced GFM BESS projects across Americas markets.
• Define control philosophies and sequences of operation across BESS and hybrid plant configurations (PV, wind, thermal).
• Drive alignment with utilities, ISOs, and regulators on interconnection, grid code compliance, and dynamic performance requirements.
• Coordinate EMT/RMS modeling, controls validation, and compliance deliverables with inverter vendors, GID, and Modeling teams.
• Support technical negotiations with key stakeholders on performance, testing, and compliance strategy.
• Validate GFM performance and coordinated plant behavior through commissioning and testing.

Technology Strategy & Innovation

• Evaluate emerging technologies (e.g., SSTs, advanced controls) to shape Fluence’s roadmap and market entry strategy.
• Develop business cases and executive materials to inform product, platform, and investment decisions.

Required Qualifications and Experience

• 10–15 years of electrical experience in energy storage, electrical infrastructure, power generation, or related fields.
• Proven track record closing complex, multimillion‑dollar B2B transactions with sophisticated counterparties (e.g., hyperscalers, colocation providers, utilities, developers, EPCs).
• Deep understanding of data center power requirements and stakeholders, and experience with utilities, IPPs, developers, and/or large energy customers.
• Expertise in medium‑voltage electrical distribution, load profiles, interconnection, power quality, controls/integration, and project execution constraints.
• Exceptional communication, negotiation, and executive‑level presentation skills with the ability to translate technical concepts into clear business outcomes.
• Master’s degree in electrical engineering or related discipline required.
• Professional Engineering license preferred.

Additional Skills

• Deep knowledge of energy storage technologies, grid services, and utility market design; ability to connect these capabilities to data center outcomes (reliability, cost, carbon, speed‑to‑power).
• Deep knowledge of data center electrical infrastructure and project delivery (MV/LV distribution, substations, UPS and backup generation interfaces, protection schemes, commissioning) and how a utility‑scale BESS integrates at the site or grid level.
• Experience with PSCAD modeling and hardware‑in‑the‑loop testing.
• Ability to influence without authority and collaborate across a global matrix organization.
• Highly organized, self‑directed, and comfortable operating in a dynamic environment.
