About The Position

Work as part of a multi-disciplinary team as the lead process engineer and/or senior technical advisor for multiple projects. This position is based on a hybrid work schedule and will require in-office work 3 days per week. In this role, we expect people to be willing or able to lead others who use modern tools: You are expected to lead others in taking engineering problems from issue to solution by setting expectations for using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs. Leaders in these roles often direct automation and process-improvement work, for example, how teams automate calculations, summarize technical documents, or generate design documentation and guiding when and how AI or agentic AI tools are used while ensuring results are checked. Overseeing engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs, is valued but not required. We also value additional learning, such as a minor, certificate, or other experience in Computer Science, Artificial Intelligence, Software Engineering, or related fields that enables effective oversight of automation and agentic AI-enabled engineering workflows.

Requirements

BS and/or MS in engineering from an ABET Engineering Accreditation Commission-approved program with a strong academic background.
6+ years of oil and gas industry experience in midstream and/or upstream.
Excellent oral and written communication skills required as well as a professional demeanor.
Excellent team-working skills.
Skills in pipeline hydraulic modeling including dynamic surge analysis.

Nice To Haves

Professional Engineering License is preferred.
Strong knowledge of gas plants and gas processing preferred.
Skills in HYSYS, Synergi, VMG Symmetry, and/or ProMax preferred.
Able to travel as necessary for client meetings, job site visits, start-up activities, off-site training, industry related conventions/seminars, etc. (up to 20% travel).
Overseeing engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs, is valued but not required.
Additional learning, such as a minor, certificate, or other experience in Computer Science, Artificial Intelligence, Software Engineering, or related fields that enables effective oversight of automation and agentic AI-enabled engineering workflows.
