Senior Instrument & Controls Engineer - OnSite Energy & Power (Multiple Locations)

The Senior Instrumentation & Controls (I&C) Engineer will support and lead the design and development of process/plant/building control systems for distributed generation and district energy projects, including electric, steam, chilled water, hot water, and cogeneration facilities. This position will execute and lead I&C engineering activities across the full project lifecycle on Engineering, Procurement, and Construction (EPC) and traditional Design-Bid-Build (DBB) projects, ensuring deliverables are completed in accordance with project scope, schedule, budget, and quality requirements.

The Senior I&C Engineer will serve as a discipline lead and primary client interface for I&C-related scope, providing technical direction, oversight, and mentorship to staff engineers while coordinating with multi-disciplinary teams to deliver integrated engineering solutions across varying project delivery methods.

Key Responsibilities\:

• Lead I&C engineering activities across all project phases, including Front-End Loading (FEL-1, FEL-2, FEL-3), detailed design, procurement, construction, and commissioning, for both EPC and Design-Bid-Build projects.
• Serve as the primary client point of contact for I&C scope\:
  • Interface directly with clients to define requirements, scope, and design expectations.
  • Present technical solutions, studies, and design packages.
  • Support resolution of technical issues and incorporate client feedback into design.
• Support early project development and FEL activities, including\:
  • Scope definition and development.
  • Control system and instrumentation philosophy development.
  • Conceptual and preliminary design packages.
  • Input to capital cost estimates and project schedules.
• Lead the design and development of process control systems (DCS and/or PLC), including\:
  • Control system architecture and network design.
  • I/O lists and system configuration requirements.
  • Control narratives, logic diagrams, and cause & effect diagrams.
  • HMI/graphics design concepts.
  • Development of interlock matrices and control philosophies.
• Develop and manage instrumentation design deliverables, including\:
  • Instrument lists and index development.
  • Instrument data sheets and specifications.
  • Instrument installation details and location plans.
  • Wiring diagrams, loop diagrams, and interconnection drawings.
• Support and coordinate the development of Piping and Instrumentation Diagrams (P&IDs) in collaboration with process and mechanical engineering teams.
• Perform instrumentation engineering calculations and sizing, including\:
  • Control valves and regulators.
  • Flow measurement devices (e.g., orifice plates, mag meters, etc.).
  • Thermowells and other field instruments.
• Apply knowledge of measurement technologies and control strategies to select appropriate instrumentation for process variables such as pressure, temperature, flow, level, and analytical measurements.
• Develop control system design criteria, functional specifications, and system requirements in alignment with project and client standards.
• Participate in process safety activities, including Hazard and Operability (HAZOP) studies and design reviews, and incorporate findings into control system design.
• Lead procurement support activities for I&C scope, including\:
  • Development of technical specifications and RFQ documentation.
  • Technical bid evaluations and vendor selection support.
  • Review and approval of vendor submittals.
• Coordinate with control system vendors and third-party suppliers to ensure compliance with project requirements, including participation in Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT).
• Perform quality reviews of engineering deliverables to ensure compliance with applicable codes, standards, and company procedures.
• Provide technical support during construction, installation, and commissioning phases, including field inspections and issue resolution.
• Lead field investigations, site visits, and data collection efforts for both new and existing facilities.
• Provide leadership, mentorship, and technical guidance to assistant and staff engineers\:
  • Delegate work assignments and review deliverables.
  • Support technical development and knowledge sharing within the team.
• Coordinate effectively with other engineering and architectural disciplines to ensure a cohesive and integrated design approach.
• Prepare and present technical reports, studies, and documentation for clients and internal stakeholders.
• Ensure compliance with company, client, and site safety policies.
