Datacenter SA/Sales Engineer

About Teraplex

Teraplex fabricates fully integrated modular AI compute ready data centers. We deliver productized 2 to 5 MW data center clusters and the power infrastructure that feeds them: LV switchboards, MV switchgear, modular substations, gensets, and SCADA, coordinated on one schedule. Our customers are AI cloud operators, data center developers, and energy companies that cannot wait out US equipment backlogs.

About the role

Part-time contract, full-time reviewable within 180d | Remote, US-based

• Site data. Own the site data request: utility service size and voltage, interconnection status, one-line diagrams where they exist, site and pad constraints, cooling constraints, network path, permitting status, and schedule drivers. Send it, follow up on it, and review the responses for gaps and contradictions.
• Configuration review. When a prospect requests a configuration, verify that it works: IT load against electrical capacity against cooling, redundancy level, generator sizing against step loads, service rating against connected load, voltage and frequency compatibility.
• Proposal support. Draft the technical sections of budgetary proposals from written inputs.
• RFQ evaluation. Review manufacturer and fabricator responses to our requests: completeness, technical compliance, exclusions and assumptions, testing scope, and the linkage between schedule and payment. Build clear comparison tables and draft the follow-up questions.
• Technical calls. Join prospect and supplier calls as the engineering participant. Document what was said, what was claimed, and what still requires written confirmation.

Requirements

• 8+ years in data center facilities, power systems, or critical electrical infrastructure, including customer-facing technical work (presales/solutions engineering, application engineering, owner's engineer, commissioning, field engineering).
• Able to check compute loads against power and cooling: rack densities, heat rejection, airflow, and liquid cooling as used in current AI and HPC deployments.
• Coordinate and process one-line diagrams, equipment submittals, MEP drawings, and factory quotes
• Working knowledge of LV distribution (480 V class) and MV equipment (through 35 kV class): switchboards, switchgear, transformers, generator integration, plus data center cooling and mechanical basics.
• Have written technical proposal, design-basis, or RFP/RFQ response content
• Comfortable with early stage: uneven workload, no support staff, checklists you build yourself.

Nice to have

• PE license (electrical or mechanical) or a recognized data center credential.
• Hands-on work with high-density GPU or HPC racks: in-rack power distribution (busway, rack PDUs), direct-to-chip liquid cooling, CDUs, and heat-rejection equipment.
• Commissioning or start-up experience in data center facilities, including integrated systems testing.
• Direct work with containerized or modular data centers, BESS, or skid-built power equipment.
• MEP design or owner's-engineer experience from pre-design through post-occupancy.
• Familiarity with US approvals: NEC, UL/NRTL listing paths, the IEEE C37 family, and utility interconnection processes.
• Experience evaluating fabrication quotations: DFM comments, FAT scope, first-article expectations.
• Familiarity with the documentation side of importing heavy electrical equipment.
