Senior Thermal Mechanical Engineer

Antora Energy Sunnyvale, CA

  • Expired: over a month ago. Applications are no longer accepted.
Job Description

Antora Energy is on a mission to stop climate change by commercializing a new class of ultra-low-cost energy storage. We are committed to building a diverse, passionate, and creative team dedicated to providing clean, reliable, and affordable energy to everyone on earth.

Position Summary

Lead the design of a system to extract useful process heat (e.g., thermal oil, steam, etc.) from an ultra-high temperature (>1500℃) thermal storage system in an efficient, reliable, safe, and cost-effective manner.


Roles & Responsibilities

  • Drive internal and external cross-functional teams on the definition, design, prototyping, validation, and hand-off to mass production of the process heat extraction subsystem.
  • Coordinate with the internal & external engineering teams on how the process heat is extracted from the system in a manner that can be efficiently transported across the site for the customer's end use.
  • Define & execute experimental and numerical investigations to inform process heat extraction designs and their integration into the broader system.


Key Qualifications

  • Bachelors or equivalent in an engineering or technical field (e.g., mechanical, thermal, chemical, aerospace, etc).
  • 8+ years of experience in activities such as designing, costing, prototyping, and working with large-scale process heat engineering projects that span multiple engineering disciplines.
  • Strong understanding of heat transfer and mechanics of materials.
  • Ability to develop and run computational models of device and component performance, including steady-state and transient heat transfer and thermal-mechanical stress analysis.
  • Familiarity with industry agencies for performance and safety. Eg: ASME, UL, ETL, CSA etc. and other local jurisdiction regulations.
  • Excellent oral and written communication skills.
  • Empathy, sensitivity, and ability to effectively interact with a broad and diverse range of colleagues.


Additional Qualifications Desired

  • Experience in the power/energy sector working with high temperatures, such as molten salt thermal energy storage (TES), concentrating solar power (CSP), thermal power plant design, boiler/superheater/heat exchanger design, advanced nuclear, pyrolysis, high-temperature metals/ceramics production, heat treatment, first-of-a-kind plants, etc.
  • Hands-on experience designing high-temperature/high-pressure  thermal fluid systems (e.g. piping systems for steam, thermal oil, molten salt, air, etc.), ensuring safe serviceability and maintenance of systems and components.
  • Hands-on experience commissioning steam and compressor systems.
  • Demonstrated knowledge of computational multi-physics  software, such as ANSYS Fluent, COMSOL, STAR-CCM+, or SolidWorks Flow Simulation.


We encourage you to apply even if your experiences and qualifications deviate somewhat from this list.
