About Helion

We are a fusion power company based in Everett, WA, with the mission to build the world's first fusion power plant, enabling a future with unlimited clean electricity. Our vision is a world with clean, reliable, and affordable energy for everyone.

Since Helion's founding in 2013, we have raised $1.5 billion from long-time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors including Thrive Capital, LightSpeed Venture Capital, SoftBank, and others to propel us forward. Our current prototype, Polaris, has reached record-breaking plasma temperatures of 150 million degrees Celsius (13 keV). Helion is continuing to iterate and on the path to the world's first fusion power plant, Orion.

This is a pivotal time to join Helion. You will tackle real-world challenges with a team that prizes urgency, rigor, ownership, and a commitment to delivering hard truths – values essential to achieving what no one has before. Together, we will change the future of energy, because the world can't wait.

As a Senior Construction Project Engineer at Helion, you will independently drive the technical and administrative execution of complex, fast-paced construction projects that enable the future of fusion energy. Working across diverse trades and project types, you will own the engineering-side workstreams, including take-offs, documentation, procurement coordination, and field execution that keep projects moving. You'll bring sound judgment to ambiguous, day-to-day situations in the field, ensuring projects are executed safely, efficiently, and to the highest quality standards. This is an onsite role at our Everett, WA office, reporting to the Facilities Build Team Leader.

• Lead core project processes, stakeholder requests, change order documentation, material procurement, and RFIs/submittals, while driving tasks to completion with a high level of accountability

• Prepare quantity take-offs and estimating support, and manage day-to-day subcontractor/trade partner coordination and scope tracking

• Serve as a key point of daily coordination between internal teams, subcontractors, and suppliers, proactively surfacing risks and blockers with clear context

• Own and continuously improve project documentation systems (meeting minutes, progress tracking, logs, closeout packages), ensuring accuracy and audit-readiness

• Conduct site walks to monitor progress, quality, and safety compliance in the field

• Operate independently in a dynamic environment with shifting priorities, upholding Helion's safety culture, and helping guide junior team members on field execution and documentation standards

Required Skills:

• 4+ years of experience independently supporting construction execution across multiple trades and project types

• Demonstrated ability to exercise independent judgment on field-level decisions in ambiguous, fast-moving environments

• Experience coordinating day-to-day with subcontractors and trade partners

• Strong organizational and project execution skills, with a track record of owning documentation and deliverables end-to-end

• Ability to read and interpret complex construction drawings and technical documents independently

• Proficiency in Microsoft Office and hands-on experience with Procore, Bluebeam, or MS Project

• Ability to work in a fast-paced, hands-on environment, adapt to changing priorities, and guide others through ambiguity
