Principal Chemical Engineer
Petaluma, CA

Beyond The Dome is seeking a highly talented Principal Chemical Engineer to join our rapidly growing team. The Principal Chemical Engineer will be one of the primary technical contributors to our first product—you will be a critical part of taking the current system all the way to a disruptive product.


Beyond The Dome is building a containerized system that destroys contaminants in water in seconds. We help industries dealing with wastewater meet their climate commitments, generate power, and clean water. Our ultra-efficient supercritical water oxidation (SCWO) process destroys over 99.9% of organic contaminants within a few seconds, including PFAS, microplastics, and pharmaceuticals, and uses the energy contained within the waste to power the process. Our long-term goal is to give people access to the best possible wastewater treatment by developing a global network of our ultra-SCWOTM systems.


We strive to be an incredibly talented, collaborative, and innovative group of people. We are solving a problem with at least a billion-dollar market opportunity, for a customer who is urgently demanding solutions. The solution demands a difficult-but-not-impossible amount of technical innovation to achieve success. We are a well-funded startup pioneering a new product within a space that is ripe for innovation.

What You'll Do:

  • Design, build and troubleshoot SCWO systems, including controls, piping, instrumentation, components, and more

  • Build complex chemical and fluid models

  • Provide pilot and field support to the team

  • Design and run lab studies

  • Contribute to long-term manufacturing efforts

  • Develop strategies to continuously reduce the iteration cycle time, and develop resources to

    accelerate improvements in performance, cost, and reliability


Does this sound like you? "I am a practical, hands-on chemical engineer with a wide base of knowledge around pilot-scale systems, controls, custom fabrication, and prototyping. People count on me to make theory into reality. I am constantly solving challenging operational problems resulting in practical, efficient, and economical solutions. There is no problem that I am afraid of tackling." Ideally, you come from a fast-paced environment, having completed difficult projects with multidisciplinary groups. You are a persistent blank-page problem solver, troubleshooter, and craftsman.

Your background should include a bachelor’s degree in Chemical Engineering or closely related field, and extensive experience in:

  • Chemical processing, power generation, combustion, multiphase fluid systems, or closely related processes

  • Hands-on operation of process equipment such as reactors, heat exchangers, pumps, and instrumentation

  • Field pilot operations

  • Industrial R&D, ideally at hardware startups

  • Chemical process modeling (HYSYS), chemistry, thermodynamics, controls/SCADA, P&ID, reactor

    design, heat exchanger selection/design, kinetics, or similar

Even better, your background includes:

  • An advanced degree in Chemical Engineering

  • P.E. license (any state, but ability to get license in California)

  • A track record of leading and managing growing teams

  • Experience with pressurized and/or hot systems, e.g., SCWO, rockets, oil and gas, nuclear

  • Extensive experience with several software packages, e.g., Autodesk, SolidWorks, Ansys, Python

Beyond The Dome offers competitive salary, equity, generous benefits, and a great work environment. We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
