Intermediate Piping Materials Engineer

What Vista Does  Vista Projects is an integrated engineering firm who has been solving complex challenges in the energy industry since 1985. We are innovators at our core. We continually find better, smarter ways to design and deliver oil and gas projects, and we are proud to be contributing on some of the most exciting low-carbon and synthetic fuel developments in the North America.

For our people, that means meaningful, varied work and a real chance to shape how modern engineering gets done.
We are innovators in the energy industry. We actively find ways to improve how oil and gas projects are designed and delivered, and we are contributing to some remarkable low-carbon and synthetic fuel developments; including electro sustainable aviation fuel (eSAF) and gas-to-liquids (GTL) projects. We are headquartered in Calgary and maintain a satellite office in Houston.
Why We Do It  The world needs energy, and better engineering makes the projects that deliver it safer, more efficient and more sustainable. Our multi-discipline teams have designed some of the most challenging and successful projects in the North American energy sector, from early‑stage studies and pilots to large‑scale commercial expansions. We take pride in doing that work well, and just as much pride in continuously improving how we do it.
What You Would Do in This Role  Own your scope and grow your impact. As an Intermediate Piping Materials Engineer, you will independently deliver piping materials and engineering scope on EPC projects and MOC programs for SAGD, oil sands, and gas processing facilities, from concept through detailed design and construction. You will act as a sub‑lead on smaller projects or work packages, guide junior engineers, and expand your expertise into SAGD pipelines.

You will also help shape how the discipline works, using Vista's intelligent, data‑centric tools to deliver safe, code‑compliant, and constructible designs that meet quality, cost, and schedule objectives.
