Client is a widely trusted innovator of IT services, including data center, enterprise IT, and unified communications. Founded by a team of passionate experts, Client aims to achieve customer success through technology enablement, bridging technical gaps to help enterprises expand globally. The company has gained trust from some of the world's leading international companies.

**About the Role

**,We are seeking a Sr. Pre-Sales Engineer - Data Center Infrastructure to lead the technical and commercial development of customer solutions across data center power delivery, cooling, lowvoltage, fit-out, and modular infrastructure programs. This role partners closely with Sales to translate customer requirements into clear scopes, technically sound solutions, accurateestimates, pricing packages, and compelling proposals across multiple concurrent opportunities. The ideal candidate combines hands-on mission-critical infrastructure experience with strongestimating, proposal development, and customer-facing communication skills. This person will coordinate with electrical, mechanical, program management, construction, procurement,operations, vendors, subcontractors and customers to clarify requirements, develop the solution and execution approach, identify risks and assumptions, and establish a complete handoff from pre-sales to delivery.

**Key Responsibilities

**

Lead pre-sales engineering and estimating activities for data center infrastructure opportunities across power delivery, cooling, liquid cooling, low voltage, fit-out, and modular solutions.
Partner with Sales during discovery to understand customer business objectives, technical requirements, site conditions, schedule constraints, commercial expectations, and decision criteria.
Develop solution concepts, basis-of-design narratives, scope descriptions, equipment strategies, conceptual layouts, system architectures, and implementation approaches that align with customer requirements and Client capabilities.
Own the technical development of RFP, RFQ, and proposal responses, including compliance matrices, technical narratives, assumptions, exclusions, clarifications, deliverables, and alternate solutions.
Prepare conceptual and detailed cost estimates covering equipment, materials, labor, subcontractors, engineering, logistics, commissioning, travel, contingency, and other project costs.
Develop Bills of Materials (BOMs), quantity takeoffs, labor-hour estimates, vendor bid packages, and pricing workbooks to support complete and traceable estimates.
Solicit and evaluate quotations from equipment manufacturers, distributors, subcontractors, engineering firms, and other delivery partners; normalize bids and resolve scope gaps before pricing is finalized.
Partner with Sales and leadership to develop pricing strategy, margin scenarios, alternates, value-engineering options, and commercial recommendations.
Review customer drawings, specifications, site information, equipment lists, schedules, and contract documents to identify scope requirements, interfaces, dependencies, and technical or commercial risk.
Coordinate electrical, mechanical, controls/BMS, low voltage, structural, architectural, fire protection, network, commissioning, and construction inputs into an integrated customer solution.
Lead internal solution and estimate reviews to validate technical compliance, constructability, delivery approach, schedule, resource requirements, cost basis, and risk prior to proposal submission.
Prepare and deliver customer-facing technical presentations, solution workshops, proposal reviews, and clarification sessions; explain design intent, tradeoffs, assumptions, interfaces, and execution strategy clearly.
Respond to customer technical questions and drive closure of open items throughout the sales cycle, documenting decisions and changes that affect scope, price, schedule, or risk.
Conduct customer site walks and existing-condition assessments as needed to validate available capacity, installation constraints, tie-in requirements, access, logistics, phasing, and constructability.
Maintain estimating templates, cost databases, rate cards, proposal standards, lessons learned, and reusable solution content to improve speed, consistency, and estimate accuracy.
Coordinate with Program Management and delivery teams to establish a complete presales-to execution handoff, including scope, estimate basis, customer commitments, assumptions, exclusions, risks, schedule, vendor quotations, and outstanding actions.
Support change-order pricing and scope clarification when pre-award assumptions or customer requirements change during project development.
Represent Client as the senior technical and estimating lead in customer meetings, partner discussions, and executive opportunity reviews.

**Qualifications

**

Bachelor's degree in electrical engineering, mechanical engineering, construction management, estimating, or a related technical discipline; equivalent mission-critical industry experience may be considered.
7+ years of experience in pre-sales engineering, solutions engineering, estimating, design-build, construction, or project development for data centers, mission-critical facilities, semiconductor facilities, advanced manufacturing, or other high-availability infrastructure.
Proven experience developing technical solutions, estimates, pricing packages, and proposals for complex infrastructure projects.
Strong working knowledge of data center power distribution, including medium- and lowvoltage systems, PDUs, busway, and associated distribution equipment.
Strong working knowledge of data center cooling systems, including chilled-water systems, CRAH/CRAC equipment, chillers, pumps, heat exchangers, CDUs, secondary cooling loops, RDHx, and liquid-cooling infrastructure.
Working knowledge of low voltage, structured cabling, controls/BMS, fire protection, modular/prefabricated infrastructure, commissioning, and site fit-out interfaces.
Ability to read and interpret drawings, one-line diagrams, P&IDs, specifications, equipment schedules, BIM models, scopes of work, and contract documents.
Experience performing quantity takeoffs, labor and material estimating, vendor bid analysis, scope leveling, cost-risk evaluation, and estimate reconciliation.
Experience preparing RFP/RFQ responses, technical narratives, compliance matrices assumptions and exclusions, and customer-facing proposal content.
Proficiency with estimating and document-review tools such as Microsoft Excel, Bluebeam Revu, AutoCAD, Revit, or comparable platforms; experience with CRM, ERP, and project-management systems like Procore is ideal.
Strong commercial judgment and understanding of pricing, margin, contingency, alternates, value engineering, and change management.
Excellent written and verbal communication skills, with the ability to explain complex technical solutions to customer engineering, procurement, operations, and executive stakeholders.
Proven ability to manage multiple concurrent opportunities, prioritize deadlines, and coordinate across Sales, Engineering, Program Management, Construction, Procurement, vendors and customers.
