Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Principal EPC Engineer - Power & Energy Systems Architect - **Company:** STN, inc. - **Location:** Odessa, TX, United States - **Experience:** Expert - **Salary:** $150,000.0 - $200,000.0 - **Contract:** Temporary contract - **Skills:** Artificial Intelligence, Data Centers, Supervisory Control and Data Acquisition (SCADA), Value Engineering, Physical Design - **Published:** July 4, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=048abf8b85d5c528 ## About the Role * BS in Electrical Engineering (or related); PE license strongly preferred (TX PE or ability to obtain). * 10+ years in EPC of power systems for data centers, utilities, industrial, or large-scale generation. * Demonstrated ownership of HV interconnection AND MV distribution design on projects at the tens-to-hundreds-of-MW scale. * Direct experience architecting on-site generation and/or microgrids - gas turbine paralleling, synchronization, and islanding. * Fluency with NEC, IEEE, NERC, and ERCOT interconnection requirements; power-system studies (load flow, short circuit, arc flash, protection coordination). * Experience integrating BESS at grid scale and coordinating storage with generation and utility supply., * Hyperscale / AI data center power design experience (liquid-cooled, high-density racks). * ERCOT market and TCEQ air-permitting familiarity. * Hands-on with tools such as ETAP, SKM, or PSS/E; SCADA/EMS and microgrid controls. * Track record standing up a discipline or serving as sole senior authority on a fast-moving development program. ## Description STN is seeking a Principal EPC Engineer to serve as the single technical authority for all engineering, procurement, and construction of power and energy systems across our AI/GPU data center campuses. This is a hands-on architect role: you own the electrical one-line from utility interconnection through the rack, and you architect on-site generation and storage. You will lead high-voltage and medium-voltage distribution design and the behind-the-meter gas microgrid that keeps our compute load resilient. You are the person who signs off that the power system is buildable, code-compliant, and bankable. Core Responsibilities High-Voltage (HV) Systems * Own utility interconnection design and coordination (ERCOT/TSP), including the point-of-interconnection, main step-up transformer, and HV switchyard architecture. * Architect substation and HV switchgear layouts, protection & relaying schemes, grounding, and arc-flash studies. * Direct interconnection studies, SCADA/telemetry requirements, and compliance with NERC/ERCOT and applicable interconnection agreements. Medium-Voltage (MV) Systems * Design the MV collection network - feeders, switchgear, ring-bus or radial topology, and MV-to-LV transformation to the data hall. * Coordinate protective device settings, selectivity, and fault-current studies across the MV distribution. * Integrate MV distribution with BESS PCS tie-ins and generation step-up so storage, generation, and utility power operate as one coordinated system. Gas Microgrid & On-Site Generation * Architect the behind-the-meter gas microgrid: aeroderivative gas turbines (e.g., TM2500 / LM6000-class), fuel supply and conditioning, and synchronization/paralleling with utility and BESS. * Design microgrid controls and islanding/black-start logic, load-shedding, and seamless transfer between grid-connected and islanded operation. * Own emissions and combustor strategy (SAC + SCR vs. DLE), water/NOx balance, and TCEQ air-permitting coordination. * Integrate LFP BESS as the bridging/resilience layer (not traditional UPS) and coordinate the row-level transient layer with bulk storage. EPC Program Ownership * Serve as design authority across all EPC packages - set standards, review and stamp deliverables, and hold EPC contractors and OEMs to spec. * Own the electrical scope of RFPs, vendor/EPC selection, and technical evaluation of quotes (pricing, warranty, DoD/performance terms, reference history). * Drive value engineering, LCOE modeling inputs, long-lead procurement planning (turbines, transformers, switchgear, BESS), and critical-path management. * Interface with permitting, AHJs, insurers, and lenders' independent engineers to keep designs bankable and code-compliant. ## Related Videos - [Your next 10x engineer isn't in your city.
