What is the difference between Vacuum System Engineer vs Mechanical Engineer?

AspectVacuum System EngineerMechanical Engineer
Required CredentialsBachelor's in Mechanical, Electrical, or related field; certifications in vacuum technologyBachelor's in Mechanical Engineering; professional engineering license often preferred
Work EnvironmentDesigning, testing, and maintaining vacuum systems in labs, manufacturing, or research facilitiesDesigning and analyzing mechanical systems across various industries
Industry UsageSpecialized in vacuum technology applications in industries like semiconductor, aerospace, and researchBroadly used across manufacturing, automotive, aerospace, and consumer products

While both roles require engineering fundamentals, Vacuum System Engineers focus specifically on designing and maintaining vacuum systems, often requiring specialized knowledge of vacuum physics and technology. Mechanical Engineers have a broader scope, working on various mechanical systems. The roles overlap in credentials and work environment but differ in specialization and industry focus.

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.

What You Will Be Doing:

  • Own hardware designs for systems related to vacuum systems on Helion\'s fusion generators. You will solve multidisciplinary engineering problems that are necessary for deploying fusion energy to the world and act as a culture driver on a growing team. You will report to the Senior Manager of Mechanical Engineering, and this is an onsite role located at our Everett, WA office.

  • You Will:

  • Own design of novel high-vacuum system for pulsed fusion generator and prototype

  • Drive system definition from requirements derivation, high-level CONOPs, P&ID and component selection through hardware commissioning

  • Perform analysis with in-house and out-of-house tools and hold design reviews to gather feedback and iterate to a fully functioning system

  • Work hands-on alongside experienced technicians to implement your hardware designs

  • Work cross-functionally to negotiate interfaces with other fusion generator subsystems

  • Learn from experts to expand your engineering skillset and domain knowledge

  • Troubleshoot hardware issues as they arise on integrated fusion generators

Required Skills:

  • Bachelor\'s degree in engineering

  • 3+ years of professional experience delivering on full-scope engineering projects (including schedule ownership)

  • Experience applying engineering first-principles and method-based thinking to challenging problems

  • Hands-on exposure to a variety of engineering disciplines (fluids, mechanical, controls)

  • Experience using CAD software (e.g. NX, Solidworks)

Benefits

Our total compensation package includes benefits, including but not limited to:

  • Medical, Dental, and Vision plans for employees and their families
