Full Job Description

Chemical Process Engineer

Department: Engineering | Reports To: Engineering Manager | Experience: 2–5 Years

About the Role

We are seeking a technically strong Chemical Process Engineer with a solid oil and gas background to join our engineering team. This role centers on process simulation, P&ID/PFD development and interpretation, and day-to-day collaboration with operations, controls, instrumentation, and piping disciplines. You will be expected to hit the ground running with simulation tools and to work confidently with process documentation both on paper and in the field.

Key Responsibilities

Develop, run, and maintain process simulations using ProMax, HYSYS, Aspen Plus, ChemCAD, or equivalent tools to support design, optimization, and troubleshooting
Perform rigorous mass and energy balance calculations for new and existing process systems
Create, review, and redline P&IDs and PFDs in accordance with project and client standards; identify and resolve discrepancies between design documents and installed equipment
Conduct field walks to verify installed equipment against P&IDs, recognizing and interpreting all major components including vessels, heat exchangers, rotating equipment, control valves, instrumentation, and specialty items
Support capital projects from FEED through commissioning, including equipment datasheets, vendor technical review, and startup assistance
Collaborate with instrumentation, controls, and piping engineers to ensure process requirements are properly reflected in design deliverables
Participate in HAZOPs, PHAs, and MOC reviews; contribute process expertise to safety evaluations
Troubleshoot process upsets and deviations; develop and implement corrective actions in coordination with operations
Prepare and maintain engineering calculations, technical reports, and procedures to applicable standards
Support environmental and regulatory compliance activities as required by project scope

Required Qualifications

Process Simulation — Non-Negotiable

Minimum 1–2 years of professional (post-degree) hands-on experience with at least one of the following: ProMax, Aspen Plus, Aspen HYSYS, or ChemCAD
Demonstrated ability to build, troubleshoot, and interpret simulation models independently — not limited to academic coursework
Oil and gas process experience strongly preferred; candidates with refining, midstream, gas processing, or LNG backgrounds are well-positioned for this role

P&IDs, PFDs, and Mass & Energy Balances — Non-Negotiable

Proven ability to read, develop, and mark up P&IDs and PFDs to industry standards (ISA, ASME, or company-equivalent)
Must be able to identify all major P&ID components by symbol and by sight in the field: vessels, columns, heat exchangers, pumps, compressors, control valves, safety valves, instrumentation tags, and specialty items
Comfortable walking down installed systems and reconciling field conditions against P&ID documentation
Proficiency in mass and energy balance development and closure for process systems

General

Bachelor of Science in Chemical Engineering
2–5 years of professional process engineering experience in oil and gas or a closely related process industry
Strong foundation in thermodynamics, fluid mechanics, and heat transfer as applied to real process systems
Ability to produce clear, well-organized engineering documentation and communicate technical content effectively across disciplines

Preferred Qualifications

ProMax experience specifically, particularly for amine treating, glycol dehydration, or NGL fractionation applications
Working familiarity with instrumentation and controls concepts: control loops, transmitter types, control valve sizing, DCS/PLC interactions — sufficient to collaborate effectively with I&C engineers
Basic piping familiarity: pipe specifications, line sizing, valve types, and the ability to read isometric or plan drawings
Engineer-in-Training (EIT) certification or active pursuit of Professional Engineer (PE) licensure
Experience participating in HAZOP studies or other process safety reviews
Familiarity with applicable codes and standards: API, ASME, NFPA, EPA/OSHA PSM

Work Environment

This position involves regular time split between office and field/plant environments. Use of PPE is required in operational areas. Some travel to client sites or project locations may be required.

We are an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, disability, or veteran status.

Pay: $65,000.00 - $120,000.00 per year

Benefits:

Dental insurance
Health insurance
Life insurance
Paid time off
Professional development assistance
Referral program
Tuition reimbursement
Vision insurance
