Locations & Work Flexibility

Primary location:
Mobile, AL. Additional office options: TX, LA, SC, GA, PA. Hybrid or interoffice execution support may be available. Relocation assistance may be offered based on role and location.

This role is responsible for the complete electrical and instrumentation design of complex industrial projects. The position requires advanced technical expertise, strong judgment, and the ability to lead discipline efforts on small to mid‑sized projects. Work is performed under general supervision and includes collaboration across multiple engineering disciplines.

• Design & Engineering – Execute full‑scope electrical and instrumentation designs using advanced engineering techniques and analysis; develop conceptual layouts, preliminary designs, detailed calculations, sketches, and material take‑offs appropriate to project phase and estimate level; produce electrical deliverables including 15kV/5kV power system single‑line diagrams, equipment specifications, MCC single‑line diagrams, and other installation specifications; create electrical room layouts, cable schedules, grounding, lighting, power, and instrumentation plans;
  
  develop control panel layouts and installation details; verify designs for code compliance, accuracy, and adherence to specifications and design standards.
• Project Execution & Coordination – Review project scope, specifications, and design criteria at assignment and proactively communicate scope or design changes; coordinate electrical/instrumentation activities with discipline leads and other engineering teams; serve as discipline lead on small to mid‑sized projects as required; develop work‑sharing packages and provide interoffice execution leadership; estimate engineering hours, track progress, and assess quality of electrical/instrumentation work;
  
  support development of construction cost estimates, schedules, and man‑hour budgets.
• Technical Leadership & Support – Provide technical guidance and mentoring to less experienced engineers and designers; review and check calculations and drawings completed by others; assist designers with layout and detailing challenges; advise senior engineers on identified design or scope changes; compile electrical and instrumentation bid packages for procurement and subcontract pricing.
• Construction & Field Support – Review vendor drawings, fabrication drawings, and construction submittals for technical compliance; perform field work to gather data, verify tie‑ins, and support construction and startup activities; provide onsite support during commissioning and startup phases.
• Instrumentation & Controls – Contribute to P&IDs related to measurement and control; develop control narratives and instrumentation specifications; specify instrumentation, analyzers, control systems, and actuated valves; size control valves using appropriate software tools; apply ISA standards and best practices for instrumentation and control systems.

• Education & Credentials – Bachelor or Master of Science in Electrical Engineering from an accredited university (required). 10+ years of industrial electrical and instrumentation engineering experience. Proven ability to act as Engineer of Record when required.
• Technical Skills – Strong working knowledge of the National Electrical Code (NEC); experience with lighting level calculations, wire, conduit, and overcurrent protection sizing, voltage drop and short‑circuit calculations, cable tray and conduit routing and fill calculations, MCC and substation loading analysis; ability to develop specifications for low‑ and medium‑voltage equipment including MCCs, switch gear, motors, VFDs, and unit substations; proficiency in developing installation documents based on vendor drawings;
  
  familiarity with 15kV/5kV systems, equipment, and above‑/below‑ground installation practices; working knowledge of CAD software (AutoCAD, Micro Station, or both); programming experience with PLCs, HMIs, and/or DCS platforms is a plus.
• Professional Competencies – Strong organizational skills with accurate estimation of task completion; clear understanding of schedule constraints and…
