Backed by top climate and technology investors, Critical Energy is scaling rapidly.
Our Mission:
To build an abundant, low-cost, 100% clean energy future through groundbreaking geothermal innovation.
We are a team of passionate engineers, designers, and visionaries building cutting-edge solutions to meet the world's energy needs with 100% clean energy. We are in the initial stages of development and building our team. This is your chance to join on the ground floor of something big! If you are ready to work at a fun, fast-paced, groundbreaking organization that is positioned to revolutionize geothermal energy, apply today!
About the Role:
We are seeking a versatile Senior Systems Engineer with experience in thermal and fluid dynamics to support the design, development, testing, and optimization of clean energy power generation systems. Collaborating with engineers across the company, this Systems Engineer will take ownership from cradle to grave and help drive the project through completion. This role focuses on system-level modeling, thermal management, and fluid flow analysis, primarily at the 1D level, across components such as heat exchangers, turbines, pumps, cooling & lubrication loops, and other balance-of-plant subsystems.
The ideal candidate will bridge system architecture, physics-based modeling, and product development, ensuring industry-leading performance, reliability, and integration of complex energy systems.
The role will involve collaborating closely with other members of the Systems team in addition to Turbomachinery, Supply Chain, Manufacturing, Field Ops, and others. Candidates must be willing to be flexible in their work and be willing to embrace new learning opportunities and expand their comfort zone to benefit the growth of Critical Energy.
The title of this role may be adjusted based on the candidate's qualifications and experience.
Experience specifically with power generation or process plant systems is not a requirement but is a significant bonus.
Responsibilities:
  • Define system requirements, interfaces, and performance budgets for thermal and fluid subsystems
  • Own system PFD and P&ID
  • Develop sub-system and system-level models to calculate steady, transient, and off-design thermal and fluid behavior using commercial analysis tools or in-house tools (e.g., Python code)
  • Support system trade studies evaluating performance, efficiency, and cost impacts
  • Support the integration of components including heat exchangers, pumps, fluid management systems, piping networks, and other auxiliary and support systems
  • Perform hand calculations using first principles to size components, determine flow rates, estimate component and system efficiency, etc.
  • Perform CFD and thermal analysis to evaluate heat transfer, pressure losses, flow distribution, and efficiency
  • Identify, outline, and support component-level and sub-system testing required for risk mitigation
  • Assist in the development of test plans and instrumentation strategies to validate thermo-fluid performance
  • Analyze experimental data to refine models and improve system design
  • Support development of control strategies related to thermal and fluid system performance
  • Generate technical documentation including system specifications, modeling reports, design trade studies, test analysis reports
  • Develop and manage relationships with third-party vendors
  • Support Field Ops teams with technical expertise and advice after product delivery and accept feedback on possible design improvements
  • Other related tasks as defined by your supervisor that add value to the design needs

Required Qualifications:
  • Bachelor's degree in mechanical engineering or related field, or equivalent experience
  • 5+ years of proven experience in systems engineering or highly related role, with a strong portfolio of projects involving diverse and integrated machinery

  • Experience with a modern CAD package and a willingness to immediately self-teach proficiency in Siemens NX
  • Excellent analytical and critical thinking skills
  • Highly self-motivated with effective communication and team-working skills

Basic Experience:
  • Experience with components and sub-systems common to power generation or process plants, like heat exchangers, pumps, turbines, valves, piping, fittings, sensors, and fluid management systems
  • Understanding of thermodynamic cycles (e.g., Rankine, Brayton)
  • Experience generating 3D models and managing assemblies in CAD while ensuring proper fit and function
  • You have built 1D models of thermo-fluid systems using commercial software (e.g., Aspen, Dymola)
  • Proven experience using Python or another coding language to build thermal and/or fluid models
  • In-depth knowledge of the design and operation of heat exchangers and how to select the appropriate type for a given application
