A key enabler of Mainspring’s mission is the ability of its team to deliver solutions based on our linear generator technology that solve customer problems in the cross-section of resiliency and clean power supply.\nThe project engineering team provides the technical expertise, guidance, and support to deploy linear generators into the field efficiently-building customer confidence and enabling future scalability. This role focuses on our largest deployments: sites of 10MW and above that either connect directly to the grid or serve large load sites such as data centers.\nResponsibilities\nThis role will be responsible for:\nLeading the overall technical definition and direction of assigned projects, including site layouts, single-line diagrams, equipment selection, sequences of operation, plant controls, communication, and network security schemes, protection and metering schemes, grounding, code and grid code compliance, fuel systems, and safety systems\n\nServing as the technical integrator across electrical, mechanical, civil, controls, fuel, and utility scopes: providing design coordination, value engineering, and interface reviews so all disciplines come together into one buildable, compliant project, and collaborating with project managers, development, procurement, and other stakeholders within timelines and budgets\n\nProviding technical support to the interconnection team: supplying plant data, single-lines, and equipment models for applications, reviewing Feasibility, System Impact, and Facility Studies, and advising on technical terms in interconnection agreements\n\nFor large-load and data center sites, defining how the plant serves and protects the load, including islanding, load-following, and transfer schemes\n\nGuiding selection and specification of medium-voltage and plant interconnection equipment such as switchgear, breakers, transformers, protective relays, revenue meters, reclosers, and PPC/SCADA hardware, plus fuel equipment such as gas regulators and valves; developing specifications, sequences of operation, EPC scopes of work, design standards, and testing procedures; and supporting procurement and proposal requests\n\nWorking directly with clients & engineering partners to translate project requirements into official plan sets using best practices, QA/QC standards, and due diligence; answering RFIs, approving submittals, and reviewing documents and designs to close gaps in function, performance, scope, and responsibility from initial design through commissioning\n\nApproving design variances, independently resolving engineering modifications to maintain design intent and schedules\n\nConducting engineering reviews of site assessments, inspections, and power system studies (load flow, short circuit, coordination, arc flash), and ensuring plant controls and protection settings meet utility, ISO/RTO, IEEE 1547/2800, and applicable NERC/FERC requirements, including ride-through, reactive power, and telemetry\n\nMonitoring changes to regional grid codes, utility interconnection handbooks, and IEEE/NERC standards, proactively compiling compliance risks and necessary product adaptations\n\nSupporting permitting for large facilities in coordination with development, environmental, and AHJ stakeholders\n\nLeading final grid code compliance demonstrations, including NERC/IEEE (1547/2800) model validation and protection relay checkout, and supporting commissioning and energization activities such as witness testing, metering checkout, and utility acceptance testing to secure final Permission to Operate (PTO)\n\nParticipating in and developing improvement initiatives, using Lean or similar methods, that increase operational efficiency within a rapidly growing project delivery department\n\nDocumenting execution challenges and creating training materials and instructional documents to better define engineering requirements for future deployments\n\nTravelling to project sites at varying stages based on availability\n\nJob Qualifications and Experience\nB.S. degree in Electrical Engineering or related discipline (power systems emphasis preferred; Mechanical, Systems, Controls, or Mechatronics considered). Technical degree and equivalent experience may be substituted\n\nProven working experience as a project engineer or power systems engineer with 8+ years of relevant experience, including at least 2-5 years in a direct contributing role on grid-scale generation or storage projects utilizing at least some of the following:\n\nSolar PV, Central Inverters, Battery Energy Storage Systems (AC- and DC-coupled), Modular Generation Packages, Microturbines, Reciprocating Engines/Gensets, Large Fuel Cells, Cogen/CHP, Plant Controllers/DERMS, Virtual Power Plants\n\nExperience with most of the following is essential: project management, medium-voltage (5 kV+) distribution and protection system design, data acquisition and control systems (SCADA/PPC/EMS), understanding of technical drawings & construction plan sets, and electrical system troubleshooting\n\nFamiliar with construction processes, sequencing, and contractor management for large generation sites\n\nStrong grasp of balance-of-plant interfaces, including equipment foundations, structural layouts, fuel/gas delivery systems, and hazardous area requirements, with proven ability to review, cross-reference, and approve multi-disciplinary EPC design packages (single-lines, P&IDs, civil site plans)\n\nFamiliar with rules, regulations, best practices, and standards for the power generation industry, including NEC, NESC, IEEE (1547, 2800, C37 series), UL 1741, utility interconnection handbooks, regional grid codes, and the proper sizing/installation/use of power system equipment\n\nWorking knowledge of FERC interconnection requirements and NERC reliability standards as they apply to generation facilities\n\nComprehension of medium-voltage protection functions, utility-grade protective relays (e.g., SEL), revenue metering, and their use in power plant design and at the point of interconnection\n\nAbility to interpret and act on power system study results (load flow, short circuit, coordination, arc flash, power quality, dynamic/ride-through), including outputs from ETAP, SKM, CYME, or PSS/E\n\nFamiliarity with SCADA systems and power plant controllers for voltage regulation and dynamic power control, plus industrial network protocols and devices (e.g., DNP3, Modbus, IEC 61850)\n\nExcellent decision making, communication, time management, documentation, and organizational skills.
