Role Description We are seeking a senior Electrical Engineer to design Fluidstack's modular, factory-built electrical infrastructure - the electrical counterpart to our Manufacturing Engineering group. Speed-to-power at gigawatt scale depends on moving electrical scope from the field into the factory: modular e-houses, switchgear and PDU skids, prefabricated electrical rooms, and repeatable packaged power solutions. As the area SME, you will own electrical design for these productized solutions end to end - from equipment selection through design-for-manufacturability, vendor factory collaboration, factory acceptance testing, and site integration. You will turn one-off designs into standardized, versioned products that deploy across dozens of sites. Responsibilities - Own electrical design of modular and prefabricated power infrastructure for data centers: switchgear skids, modular electrical rooms, and modular data centers. - Apply design-for-manufacturability principles - standardization, tolerances, transportation and rigging constraints, factory workflows - so modules are repeatable, testable, and fast to deploy. - Develop and maintain standard designs, specifications, and configuration control for the modular product line, integrating lessons learned across deployments. - Support site integration and commissioning of modular solutions, feeding field findings back into product revisions. Qualifications - Bachelor's degree in Electrical Engineering. - 7+ years of electrical engineering experience, including data center or other mission-critical facilities. - Strong background designing modular electrical solutions for data centers - e-houses, skids, prefabricated electrical rooms, or packaged power equipment. - Solid working knowledge of the data center power chain: MV/LV distribution, switchgear, transformers, UPS, generators, ATS, and Busway systems. - Demonstrated design-for-manufacturability experience: designing equipment or assemblies for factory production rather than field-built construction. - Experience working directly with equipment manufacturers, including design reviews and factory acceptance testing. Preferred Qualifications - BIM/VDC proficiency (Revit, Navisworks, clash detection) and prefabrication planning experience. - Professional Engineer (PE) license. - Prior experience at a hyperscale data center operator, modular infrastructure manufacturer, or packaged power solutions provider. - Exposure to quality systems and production engineering (ITPs, first-article inspection, NCR processes). Benefits - Competitive total compensation package (cash + equity). - Retirement or pension plan, in line with local norms. - Health, dental, and vision insurance. - Generous PTO policy, in line with local norms. - The base salary range for this position is $200,000 - $250,000 per year, depending on experience, skills, qualifications, and location. - This range represents our good faith estimate of the compensation for this role at the time of posting. Total compensation may also include equity in the form of stock options. - We are committed to pay equity and transparency.

Role Description We are seeking a senior Substation Design Engineer to support HV/MV substation design across our data center campuses. This is an owner-side role: you will lead substation design from siting and interconnection studies through IFC, construction, FAT, and energization - directing EPCs, consultants, utilities, and equipment manufacturers across a multi-GW portfolio spanning ERCOT, PJM, MISO, and other regions. You will own the technical quality of design packages, lead the engineering studies that underpin them, and build the substation standards - Basis of Design, standard drawings, equipment specifications that allow Fluidstack to deliver repeatable substations at speed. Responsibilities - Lead HV/MV substation design (up to 345 kV and above) and MV distribution interfaces for hyperscale campuses, from concept through IFC and energization. - Review and approve EPC- and consultant-produced deliverables: physical/structural layouts, electrical drawings, protection & control packages, and construction documents. - Perform and review engineering calculations and studies: load flow, short circuit, arc flash, grounding and bonding, lightning, insulation coordination, relay coordination, and cable ampacity. - Develop scopes of work, RFPs, and equipment specifications for long-lead equipment (transformers, switchgear, breakers); run technical bid evaluations and witness factory acceptance tests. - Provide technical input to utility interconnection processes and agreements (ESAs/CDAs), coordinating with ISOs/RTOs and utility engineering teams. - Support construction, commissioning, and phased energization planning, including resolution of field issues and RCAs. Qualifications - Bachelor's degree in Electrical Engineering. - 8+ years of experience in HV/MV substation design (transmission and distribution voltages, up to 345 kV). - Demonstrated ownership of full substation design packages: one-lines/three-lines, physical layouts, grounding, raceway, and protection & control drawings. - Experience developing equipment specifications, running technical bid evaluations, and witnessing factory acceptance tests for major HV/MV equipment. Preferred Qualifications - Professional Engineer (PE) license. - Owner-side experience at a hyperscale data center operator or large industrial developer. - Direct experience with utility interconnection processes and technical inputs to ESAs/CDAs in ERCOT, PJM, MISO, or CAISO. - Experience with both AIS and GIS substation architectures. - Track record of standards authorship: Basis of Design documents, standard drawing libraries, commissioning scripts, responsibility matrices. Benefits - Competitive total compensation package (cash + equity). - Retirement or pension plan, in line with local norms. - Health, dental, and vision insurance. - Generous PTO policy, in line with local norms. The base salary range for this position is $200,000 - $250,000 per year, depending on experience, skills, qualifications, and location.

Role Description We are seeking a senior Electrical Engineer to own the architecture, standardization, and delivery of on-site and supplemental power across our data center campuses. This spans renewables power distribution (solar and wind), battery energy storage, on-site generation, and - critically - temporary power and mobile substation solutions that bring capacity online ahead of permanent utility delivery. As the area SME, you will define reference architectures that balance CAPEX/OPEX, reliability, and evaluate next-generation power technologies; and standardize design packages so quality is repeatable and project timelines shrink. You will serve as a technical escalation point for on-site power availability and performance issues, driving root cause analysis and lessons learned across the fleet. Responsibilities - Define the reference architecture for on-site and supplemental power generation and distribution, balancing CAPEX/OPEX and reliability goals. - Design and deliver temporary power and mobile substation solutions to energize facilities ahead of, or in parallel with, permanent utility infrastructure - including bridging power strategies that accelerate speed-to-power. - Lead electrical design and integration of renewables power distribution (solar and wind) and BESS into campus MV systems, including collector systems, interconnection, and protection interfaces. - Evaluate and adopt new power technologies (e.g., fuel cells, advanced battery storage, microgrid controllers) and develop the technical justification for major capital investments. - Serve as a technical escalation point for on-site power availability or performance issues, driving root cause analysis and lessons learned across sites. - Standardize design packages and operational procedures to ensure repeatable quality and minimize project timelines across the portfolio. Qualifications - Bachelor's degree in Electrical Engineering, Power Systems, Energy, or a related field, or equivalent practical experience. - 8+ years of experience in power systems, power generation, or power distribution engineering for grid-connected facilities. - Experience providing temporary power and/or mobile substations to facilities - including generator farms, rental fleets, mobile transformers/switchgear, and bridging power schemes. - Experience designing or integrating renewables power distribution (solar and/or wind), including collector systems and interconnection to MV distribution. - Strong working knowledge of MV distribution equipment: transformers, switchgear, generators, and associated protection and controls. - Proficiency performing or reviewing power system studies (load flow, short circuit, coordination, arc flash).
