I/E/C Specialist

Vitol•Houston, TX

56d•Onsite

About The Position

The I/E/C Specialist is a senior, hands-on technical role responsible for supporting construction completion, commissioning, startup, and early operations of a growing portfolio of Renewable Natural Gas facilities. This position is a field-forward individual contributor role, acting as the technical bridge between Engineering, Construction, and Operations to ensure systems are safe, functional, maintainable, and ready for long-term operations. This role requires extensive travel and direct engagement at active construction and operating sites. The I/E/C Specialist operates with significant autonomy while remaining tightly aligned with Operations leadership and project teams.

Requirements

8-12+ years of hands-on I/E/C experience in RNG, oil & gas, power generation, chemical, or similar industrial environments
Strong field experience with PLCs, HMIs, instrumentation, MCCs, VFDs, and industrial plant power systems
Proven experience supporting construction, commissioning, startup, and early operations
Practical, execution-focused mindset with strong troubleshooting skills
Ability to work independently while coordinating across multiple disciplines
Willingness and ability to travel extensively as required by project needs
Candidates must demonstrate practical familiarity with industrial automation systems, examples include:PLCs: Allen-Bradley (ControlLogix, CompactLogix), Siemens (S7), or equivalentHMIs / SCADA: FactoryTalk View, Ignition, Wonderware/AVEVA, or similarCommunications: Ethernet/IP, Modbus TCP & RTU, Profibus/Profinet, serial, fiber, radio, cellular telemetryAbility to navigate logic, troubleshoot I/O and communications faults, and support controlled logic changes under MOC
Candidates are expected to understand how the process operates and how instrumentation impacts safety, compliance, and uptime.Hands-on experience with industrial instrumentation commonly used in RNG, examples include:PressureGauge, absolute, and differential pressure transmittersLow-pressure gas service (wellfield headers, blower suction/discharge)High-pressure service (compression, upgrading skids, pipeline interface)DP transmitters for filter and vessel monitoringEmerson - Rosemount 3051, 1151, 2088Yokogawa - EJA/EJX SeriesEndress+Hauser - Cerabar, DeltabarHoneywell - SmartLine ST700/ST800TemperatureRTDs (2-wire, 3-wire, 4-wire)Thermocouples (Type J, K)Temperature transmitters for process gas, glycol, oil, and ambient monitoringOmega - RTDs, thermocouplesEmerson - Rosemount 3144P, 644Endress+Hauser - iTEMP SeriesFlowThermal mass flow meters (low-pressure gas, wellfields)Ultrasonic flow meters (gas custody transfer or monitoring)Differential pressure flow elements (orifice, venturi)Coriolis or turbine metersEmerson - Micro Motion Coriolis, Rosemount 8800 VortexEndress+Hauser - Proline Promass, ProsonicSiemens - SITRANS FSage Metering - Thermal mass gas metersLevelRadar (guided wave and non-contact)UltrasonicDifferential pressure level transmittersPoint-level devices (float, tuning fork, capacitance)Emerson - Rosemount 5300/5400 RadarEndress+Hauser - Micropilot, LevelflexVEGA - VEGAPULS, VEGAFLEXMagnetrol - Eclipse, displacer and float switchesGas analyzers (CH₄, CO₂, O₂, H₂S, moisture)Gas Composition / QualityABB - NDIR gas analyzersSiemens - ULTRAMAT, OXYMATServomex - MultiExact, SERVOTOUGHO₂ / H₂S / Safety MonitoringDräger - Fixed gas detection systemsMSA - GasGard, UltimaTeledyne, similar - O₂ and gas analyzerMichell Instruments, similar - Dew point analyzersIncludes experience with:Sample conditioning systemsCalibration gas handling and validationAnalyzer shelter integrationControl valvesEmerson - Fisher globe/ball valvesFlowserve - ValtekNeles/various - Ball and control valvesActuators & PositionersEmerson - Fisher DVC6200/6000ABB - TZIDCSiemens - SIPART PS2Rotork - Electric actuatorsSolenoidsASCO - RedHat seriesParker, similar - Industrial solenoidsElectrical Power, MCCs & DrivesExperience with low- and medium-voltage industrial power systemsTroubleshooting MCCs, motor starters, and control panelsConfiguration and diagnostics of VFDs for blowers, compressors, and pumpsAbility to read and interpret one-lines, schematics, loop diagrams, and control drawingsFamiliarity with hazardous area classifications (Class I, Div 1 / Div 2)Analyzer Shelters, Compressor Skids & Upgrading SystemsAnalyzer SheltersShelterWorksSiemens (integration packages)Familiarity with HVAC, purge systems, hazardous-area electrical designCompressors & BlowersAriel, Mayekawa, Ingersoll Rand, Lonestar VFDs & Motor ControlRockwell Automation - PowerFlex seriesABB - ACS drivesSiemens - SINAMICSGas Upgrading, Treatment & Safety Shutdown SystemsUpgrading SystemsWilexa - TSA systemsSepuran - Membrane systemsGuild Associates - PSA / nitrogen rejectionH₂S & PolishingNorit Carbon - Carbon vessels, Sulfur removal mediaPSB- Deoxogenation, molecular sieve dehydrationSafety & Shutdown-or similarEmerson - ESD systemsHoneywell - Safety ManagerDet-Tronics - Gas & flame detectionConstruction, Commissioning & Startup ExperienceProven experience supporting facilities from drawings through operation, including:Panel inspections, cable terminations, instrument installations, and punchlist resolutionLoop checks, functional testing, interlock and cause-and-effect verificationStartup troubleshooting, nuisance trip resolution, alarm tuning, and early-life reliability improvements
