Senior Principal Engineer – Instrument & Controls

Accountabilities: In this role, you will lead instrumentation and control engineering activities, oversee technical deliverables, and ensure the successful execution of complex engineering projects. Your responsibilities will include: Develop and review Piping and Instrumentation Diagrams (P&IDs), control and protection philosophies, and instrumentation and control design criteria. Prepare field instrument specifications, flowmeter and control valve sizing calculations, datasheets, and material requisitions. Develop specifications, control narratives, cause-and-effect documentation, and technical requisitions for Distributed Control Systems (DCS), Safety Instrumented Systems (SIS), Fire and Gas systems, Programmable Logic Controllers (PLC), and other control and safety systems. Prepare analyzer and analyzer shelter specifications, datasheets, and material requisitions. Produce or oversee engineering drawings and documentation, including wiring diagrams, instrument location plans, installation details, loop diagrams, panel drawings, and remote instrument building layouts. Prepare technical bid evaluations, support purchase order administration, and review supplier and vendor technical documentation. Coordinate engineering interfaces, technical requirements, and design criteria with other disciplines. Conduct site surveys and provide technical support during project execution when required. Lead small to medium-sized projects and serve as the technical lead for instrumentation and control activities on larger projects. Define engineering scopes of work, project milestones, staffing plans, resource requirements, and man-hour estimates. Monitor project progress, engineering schedules, staffing needs, and budget utilization, identifying and escalating deviations or major changes. Establish engineering design concepts and ensure the technical accuracy and compliance of project deliverables. Coordinate and monitor engineering deliverables produced by international workshare offices. Coach and mentor less experienced engineers and designers while contributing to the development and maintenance of departmental procedures. Apply recognized engineering methods, codes, and standards, including ISA, IEC, and API requirements. Evaluate and adapt engineering techniques, procedures, and systems to meet project-specific objectives. Identify scope changes, investigate technical solutions, and communicate their potential cost and schedule impacts. Ensure compliance with project engineering, quality, and Health, Safety, and Environment (HSE) procedures. Requirements: The ideal candidate brings extensive instrumentation and control engineering experience, strong technical leadership capabilities, and a proven background in large-scale energy and industrial projects. The following qualifications and skills are expected: Bachelor's degree in Electrical, Chemical, or Mechanical Engineering. At least 20 years of instrumentation and control engineering and design experience within LNG, energy transition, carbon capture, refining, and/or petrochemical projects. Professional Engineer (PE) license in Louisiana and/or Texas preferred, with the ability to obtain multistate licensure. Certification as a Certified Functional Safety Professional, Certified Functional Safety Expert, or TÜV Functional Safety Engineer is preferred. Strong expertise in P&IDs, control and protection philosophies, instrumentation specifications, and sizing calculations. Extensive knowledge of DCS, SIS, Fire and Gas, PLC, and other industrial control and safety system design and integration. Experience developing control narratives, cause-and-effect documentation, wiring diagrams, loop diagrams, and equipment layouts. Expertise in analyzer systems, technical requisitions, bid evaluations, purchase order administration, and vendor documentation reviews. Strong understanding of engineering scope development, project schedules, resource planning, budgets, and multidisciplinary technical coordination. Working knowledge of applicable ISA, IEC, and API codes, standards, and engineering practices. Proficiency in Microsoft Office, SmartPlant Instrumentation (SPI), Navisworks, and PDF markup software. Excellent written and verbal communication skills, with the ability to collaborate effectively across multidisciplinary teams. Demonstrated technical leadership, project coordination, and problem-solving capabilities. Ability to mentor engineering professionals, manage competing priorities, and make sound technical decisions. Must be authorized to work in the United States. Willingness to travel for site surveys and project support when required. Benefits: Opportunity to work on complex, large-scale EPC projects across LNG, energy transition, carbon capture, refining, and petrochemical industries. Exposure to innovative engineering technologies and major industrial infrastructure developments. Opportunities to lead multidisciplinary engineering teams and contribute to strategic technical decisions. Professional development through technical leadership, mentoring, and involvement in complex engineering projects. Collaborative environment involving international engineering teams and cross-functional stakeholders. Potential opportunities for professional engineering licensure and functional safety certification development. Travel opportunities for site surveys and project support, depending on project requirements.
