Principal Controls Engineer
Petaluma, CA

Beyond The Dome is seeking a highly talented Principal Controls Engineer to join our rapidly growing team.  The Principal Controls 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 (ultra-SCWOTM) 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, program, and troubleshoot SCWO system controls and controls hardware

  • Provide pilot and field support to the team

  • Support the electric and controls needs of the lab

  • 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 an experienced, hands-on controls engineer with in-depth knowledge of macrofluidic systems, and have demonstrated analysis and programming skills. I have several years’ experience supporting critical research, testing, and/or design projects. I am value-oriented, detail-oriented  and uses up-to-date controls tools and concepts." 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.

  • Process control, power generation, combustion, multiphase fluid systems, manufacturing, or closely related fields

  • Hands-on operation and troubleshooting of process equipment such as pumps, heaters, motors, and instrumentation

  • Safety design and implementation

  • Controls and SCADA software packages from Siemens, AB/Rockwell, AVEVA, and more

  • PLC programming languages like ladder logic, structured text, or function blocks

  • Communication protocols like MODBUS or Profinet

  • Controls hardware such as PLC’s, HMI’s, drives, I/O modules, and more

  • Control panel and wiring design

  • Field pilot operations

  • Industrial R&D, ideally at hardware startups


Even better, your background includes: 

  • Experience with process and controls simulation

  • A track record of leading and managing growing teams

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

  • Experience with additional software packages, e.g., Autodesk, SolidWorks, Ansys, Python
