Amperesand - Technical Account Manager-Data Center Power Systems
Requirements
• BS/MS in Electrical Engineering, or equivalent demonstrated technical depth in power systems. • 4+ years in a customer-facing technical role — applications engineering, technical account management, systems engineering, or design engineering with direct customer ownership. • Strong working knowledge of data center electrical design and power infrastructure: medium voltage distribution, switchgear, transformers, UPS and BESS, standby generation, transfer schemes, and common redundancy topologies. • Demonstrated ability to author single line diagrams independently — not just review them — using AutoCAD Electrical, EPLAN, Visio, draw.io, or equivalent. • Practical understanding of protection and coordination: transformer winding configurations (wye-wye vs. delta-wye) and their fault behavior, grounding schemes, ANSI protective functions, short circuit and arc flash considerations, and utility interconnection requirements. • Track record producing customer-grade technical documentation and submittal packages under revision control, and defending them in front of a demanding customer's engineering team. • Program discipline: comfortable running deliverable trackers, decision logs, and milestone schedules in Jira, Confluence, or equivalent, and holding cross-functional partners to dates. • Excellent written and verbal communication. Able to hold a technical line with a customer, say "I'll get you an answer" and then actually close the loop. • Willingness to travel up to 50% to customer sites, partners, and manufacturing, including international travel as the business expands. • Direct experience with hyperscale or colocation data center projects, from the owner, EPC, OEM, or equipment supplier side. • Background in power electronics, inverters, BESS, or medium voltage power conversion. • Experience with auxiliary power system design (48VDC / 125VDC), controls integration, and industrial protocols such as Modbus, DNP3, or IEC 61850. • Familiarity with applicable standards — IEEE C57, IEEE 1547, IEC 62477, UL 1741, NFPA 70/70E — and with compliance and certification workflows. • Hands-on FAT, commissioning, or startup experience on grid-connected equipment. • Experience at an early-stage hardware company introducing a new product category to conservative infrastructure buyers. • $145,000 - $170,000 USD • Candidate Confidentiality & Information Protection • As part of our commitment to protecting confidential and proprietary information, candidates should not disclose or provide Amperesand with any confidential, proprietary, or trade secret information belonging to a current or former employer or any other third party during the application or interview process. • Please do not submit or present employer-owned source code, schematics, designs, technical documentation, internal presentations, customer information, prototypes, or other confidential materials. Candidates should discuss their experience and accomplishments at an appropriate level and use only information and materials they are authorized to share.
Responsibilities
• Own the technical relationship with key accounts. Be the named technical point of contact for a portfolio of strategic data center customers and their OEM, EPC, and switchgear integration partners. Run the recurring technical reviews, lead design workshops, and be the person the customer's engineers call first. • Own the technical relationship with key accounts. • Author and own single line diagrams. Produce and maintain customer-facing SLDs covering the MV path, transformer winding configurations and topologies, protection devices and functions, auxiliary power distribution, generators, BESS/DC-DC interfaces, and test bed and FAT configurations. Drive these to internal review and alignment before they go out, and iterate against customer markups. • Author and own single line diagrams. • Prepare and deliver technical documentation. Own the submittal packages behind program milestones: staged design document submissions, system block diagrams, sequences of operation, state diagrams, protection function schedules, datasheets and rating plates, skid and site layouts, interface control documents, serviceable parts BOMs, and FAT plans and reports. • Prepare and deliver technical documentation. • Manage customer deliverables end to end. Maintain the deliverable schedule and design decision tracker for your accounts. Break customer commitments into internal actions across electrical, mechanical, firmware, software, compliance, quality, and supply chain; drive them to closure; and escalate early when a date is at risk. • Manage customer deliverables end to end. • Run customer communications. Own RFI and technical inquiry responses, action item logs, meeting minutes, and status reporting. Give the customer a clear, accurate, single answer — and give leadership an honest read on program health. • Run customer communications. • Support FAT, commissioning, and energization. Partner with Test, Quality, and Service on factory acceptance testing, witness events, punch list closure, site acceptance, and handover documentation. • Support FAT, commissioning, and energization. • Bring the customer's voice back inside. Translate field and interface requirements into product requirements. Represent real deployment constraints in specification and design reviews so the next generation is easier to integrate, permit, and service. • Bring the customer's voice back inside. • Support new business technically. Join technical due diligence and evaluation conversations with prospective customers, and build the confidence that Amperesand can execute. • Support new business technically.
