Role Overview

The Data Center BESS Principal Engineer is a senior-level technical role with a focus on supporting Global DC Sales while being a key individual contributor within the Sales Engineering organization. This role is responsible for supporting Sales to lead end-to-end technical strategy and solution development, as well as for coordinating cross-functionally inside Fluence across the technical teams. The DC Solutions Principal will also serve as a thought leader who can support external engagements with industry advocacy and rule setting bodies.

Key Responsibilities

Data Center Solutions
  • 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 and follow lessons learned from technical execution of advanced GFM BESS projects across Americas markets from development through commissioning and operational acceptance.
  • 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 (e.g., system operators, utilities) on performance, testing, and compliance strategy.
  • Keep abreast of and follow lessons learned from commissioning and testing to validate GFM performance and coordinated plant behavior.


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
  • Ability to work as a team player, focusing on the organization's success. Ability to work in a matrixed organization, collaborating and sharing information across multiple teams.
  • 10-15 years of electrical or mechanical 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/or enterprise electrical infrastructure, in addition to experience with utilities, IPPs, developers, and/or large energy customers.
  • Expertise to engage deeply with engineering and operations teams on topics such as 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 (e.g., 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.
