Project Manager
Project Manager
Sisu Energy & Environmental | Tulsa, OK (In Office)
Do you love being the person who keeps everything moving? The one who knows where every order stands, who’s waiting on what, and how to get a project across the finish line on time and on budget? If you thrive on juggling customers, vendors, and teams while keeping communication crisp, this role was made for you.
Who We Are
At Sisu Energy & Environmental, we help the world Power Up Responsibly. We design, engineer, install, and support emissions-reduction systems for gas turbines in power generation and data center applications, helping our customers meet environmental requirements without sacrificing performance or reliability. From engineered systems and aftermarket support to innovative technologies like FreeHeat™, our work makes energy cleaner and smarter.
Sisu has the feel of a small, founder-led company, with all the energy of a business that’s growing fast. As we take on more projects, we need a strong Project Manager to help lead the way.
The Role
Reporting directly to our Chief Operating Officer, you’ll own your projects from start to finish. You’ll be the go-to contact for customers, vendors, contractors, and our internal teams, making sure everyone is aligned, informed, and moving in the same direction. It’s a highly visible role with real ownership and a direct line to leadership.
What You’ll Do
• Be the voice of the project. You’ll serve as the primary communication point for your projects, connecting customers, vendors, contractors, and Sisu departments. Timely updates and consistent follow-up are your superpower.
• Build and manage schedules. You’ll create project schedules alongside Sisu engineering, raw material vendors, and fabrication shops, using Microsoft Project for large capital projects or when customers require it. You’ll keep customers and Sisu leadership up to date through weekly meetings and regular status updates.
• Run purchasing for your projects. You’ll request vendor quotes, create and issue purchase orders for materials and subcontract work, expedite deliveries, review and approve vendor invoices, maintain the PO log, and track spending against budget.
• Manage customer invoicing. You’ll create and submit project invoices and work with customers and our accounting team to make sure payments come in on time.
• Lead project meetings. You’ll run in-person and Microsoft Teams meetings with customers, vendors, and internal teams, keeping discussions focused and productive.
• Handle change orders. When scope shifts, you’ll cost out materials and labor, discuss margins with management, adjust schedules, and follow through until updated customer purchase orders are in hand.
• Do what it takes to deliver. Like any growing company, things come up. You’ll pitch in wherever needed to make each project a success.

• At least 5 years of project management or relevant industry experience
• A bachelor’s degree in Business or Engineering is preferred
