Job Profile Summary

Your ideas have a place here-step into a role where your work directly drives solutions in a fast-evolving energy industry. At ONEOK, you'll contribute to delivering energy products and services that power progress while gaining hands-on engineering experience in plant operations at the CANA and Canadian Valley Plant. The Engineer II will lead execution of medium‑capex facility projects within the Natural Gas Gathering & Processing business, managing projects from initiation through closeout.

This role requires an experienced Engineer who proactively drives projects to completion, builds strong, trust‑based relationships with Operations and Commercial stakeholders, and communicates clearly and transparently. Projects typically have CAPEX in the $1M-$50M range and involve coordinating cross‑functional teams and third‑party contractors to meet safety, quality, schedule, and cost objectives. You will be accountable for developing and maintaining project schedules, budgets, and milestone plans, and for ensuring milestones and deadlines are consistently met.

A core responsibility is establishing and managing all project contracts and purchase orders and ensuring work is executed in strict accordance with those agreements. You must provide regular, candid progress updates, promptly surface issues or delays, and drive effective mitigation plans while managing multiple concurrent projects. The ideal candidate brings proven facilities project and technical experience in the Midstream or Oil & Gas sectors, strong verbal and written communication skills, and a demonstrated ability to build stakeholder trust and deliver projects on a schedule and within budget.

Experience managing construction, contracts, purchase orders, and third‑party vendors are required. This position is eligible for a hybrid work schedule: in‑office presence Monday, Tuesday, and Thursday, with remote work Wednesday and Friday as project workload allows.

ONEOK offers a highly competitive total rewards package, including comprehensive health benefits, a 6% 401(k) match plus 4 quarterly company contributions through the company's profit sharing, $100,000 in life insurance, annual bonuses for all employees, and a minimum of three weeks of paid time off that recognizes your industry experience.
