Senior Pre-Sales Engineer

Vertiv is seeking a Senior Pre-Sales Engineer to support high-impact data center and mission-critical projects with a focus on low-voltage (LV) power distribution systems, including UL 891 switchboards and UL 1558 switchgear. This role operates in a fast-paced, engineering-driven environment where technical accuracy, proposal quality, and cross-functional coordination are critical to winning and delivering mission-critical infrastructure.

This position serves as the senior technical lead for pre-sales ETO engineering activities and is responsible for driving front-end technical alignment, execution readiness, handoff quality, standardization, and engineering process improvements across electrical and mechanical design support functions.

• Front-End Technical Coordination: Lead coordination activities between Applications Engineering, Design Engineering, Manufacturing Engineering, Operations, Sourcing, and Project Management.


• Pre-Sales ETO Engineering: Lead and support ETO engineering activities for LV switchboards, switchgear, power distribution equipment, and custom engineered assemblies.


• Technical Design Direction: Provide technical direction and support for electrical and mechanical design development during the quotation and proposal phase.


• Customer Specification Review: Review customer specifications, one-line diagrams, technical requirements, and project documentation to ensure compliance with customer expectations and applicable standards.


• Opportunity Support: Support engineered-to-order (ETO) and standard platform opportunities across multiple customer segments.


• Code and Compliance Oversight: Ensure quotation designs align with UL 891, UL 1558, NEC, and customer-specific requirements.


• Design Development Support: Support development of conceptual layouts, GA drawings, preliminary BOMs, control architectures, and technical submittal documentation.


• Technical Scope Validation: Review and validate technical scope, component selections, short circuit ratings, bus sizing, protection schemes, metering requirements, and mechanical configurations.


• Handoff Quality: Drive clean order handoff quality and support execution readiness prior to Design Engineering release.


• Technical Risk Assessment: Lead technical risk assessments related to manufacturability, compliance, sourcing, schedule, and customer requirements during the quotation and proposal phase.


• Sourcing Coordination: Coordinate with sourcing and supply chain teams on long lead item considerations, component availability, approved manufacturer lists, and alternate component strategies.


• Customer Technical Engagement: Support customer technical review meetings and provide technical clarification throughout the proposal process.


• Submittal Package Support: Support completion and accuracy of initial customer submittal packages during the pre-sales phase.


• Proposal Timeline Management: Support quotation schedules and proposal response timelines through effective prioritization and coordination.


• Continuous Improvement: Drive continuous improvement initiatives focused on cycle time reduction, quotation accuracy, BOM accuracy, standardization, handoff quality, and design efficiency.


• Metrics and Documentation: Support development and maintenance of engineering KPIs, proposal tracking metrics, and technical documentation processes.


• Technical Mentorship: Provide technical mentoring and guidance to electrical and mechanical pre-sales design resources.


• Downstream Rework Reduction: Support reduction of downstream engineering revisions, redesign efforts, and execution delays through improved front-end technical validation.


• Project Handoff: Support transition of awarded projects into execution teams through structured technical handoff processes.

• Bachelor’s degree in Electrical Engineering (preferred); Engineering Technology or related technical discipline accepted.


• Minimum 5 years of experience in low voltage power distribution, switchgear, switchboard, or engineered electrical systems.


• Strong understanding of LV power distribution systems, electrical protection, control systems, and mechanical enclosure design.


• Strong knowledge of UL 891, UL 1558, NEC, and related industry standards.


• Experience supporting data center, industrial, utility, or mission critical infrastructure projects.


• Ability to review electrical one-lines, schematics, GA layouts, and BOM structures.


• Experience working within ETO manufacturing environments.


• Strong communication, organizational, leadership, and cross-functional coordination skills.


• Experience with ERP, PDM, and engineering documentation systems preferred.

• Experience with IFS, Oracle, Vault, AutoCAD, SEE Electrical, or equivalent engineering systems.


• Experience supporting large scale data center infrastructure projects.


• Understanding of manufacturing processes, design for manufacturability, and cost optimization.


• Familiarity with seismic, thermal, short circuit, and compliance testing requirements.


• Direct experience with UL 891 switchboard or UL 1558 switchgear design, including drawing package development, breaker schedules, single line diagrams, and BOM structures.


• Familiarity with LV protection and control systems including overcurrent coordination, arc flash mitigation (NEC 240.87), automatic transfer schemes, and metering and communications integration.

• Based in Anderson, SC with occasional travel to manufacturing facilities and customer sites as required.


• May require extended hours during critical proposal phases and customer delivery timelines.
