About this job

Antora Energy delivers affordable, reliable energy to industry, data centers, and the grid. Our thermal batteries turn low-cost electricity into always-on heat and power, without supply-constrained critical minerals or multi-year construction timelines.

We are growing our company with people who put team and mission first, value connection through laughter and joy, and work with humility and openness. We are committed to building a diverse, passionate, and creative team dedicated to a future powered by abundant, clean, low-cost energy.

 

Position Summary

Antora Energy is seeking a self-driven and passionate individual to join our engineering team to deliver zero-carbon industrial heat and power with our novel solid state thermal battery. We are a tight-knit team that loves what we do and we strive to have an impact, working with humility and openness while building lifelong relationships along the way. The Mechanical Engineer will scope, define, and design novel mechanical systems and components for balance-of-plant (BOP) process systems for Antora Energy’s thermal energy storage projects across test and commercial sites. You will be a key technical member of a cross-functional and rapidly growing organization. Your work will directly contribute to the testing and commercial deployment of an innovative long-duration energy storage technology.

You will be responsible for mechanical design of high-temperature heat transfer and process fluid systems — piping, pressure vessels, heat exchangers, and steam generation equipment — operating at elevated temperature and MW scale.

Roles & Responsibilities

  • Full lifecycle ownership of plant mechanical components and system
  • Develop detailed mechanical design for first of a kind pressure vessels, piping and process components, meeting critical performance, cost and scalability requirements.
  • Perform thermal-mechanical analysis of hot components: differential thermal expansion between coupled structures, creep, thermal cycling/fatigue, thermal shock, and insulation/heat-loss trade-offs.
  • Select valves, seals, instruments, and fittings for hot process fluid service (gas, liquid, or two-phase), including leak-tightness, material compatibility, and actuation at temperature.
  • Identify, develop and work with vendors enabling design execution
  • Create and implement test plans to validate performance, assembly and lifetime

 

Key Qualifications

  • Bachelors or equivalent in an engineering field (e.g. chemical, mechanical,  industrial, etc.) and/or 4+ years’ experience in industrial applications engineering (oil & gas, chemicals, power plants, etc.)
  • Demonstrated experience solving novel engineering problems through commercial deployment
  • Experience with industrial mechanical equipment: Pressure Vessels, Pumps, Heat Exchangers, Air Coolers, Fans, Tanks, Piping, Valves.
  • Experience designing equipment for elevated-temperature service (>400 °C): materials selection, allowable evaluation, high-temp sealing.
  • Understanding of process-fluid hazards and their mechanical design implications (inert gas asphyxiation, hot fluid release, freeze/solidification, corrosion).
  • Working knowledge of piping and pressure vessel codes, including ASME BPVC, ASME B31, PED 2014/68/EU, CSA B51, etc

 

Additional Qualifications Desired

  • Deep engineering experience and intuition, ideally with background in:
  • Multi-wall, jacketed, trace-heated, or vacuum-insulated piping system experience
  • Familiar with concentrated solar, HRSG/boiler, nuclear primary systems, industrial furnaces, or cryogenic process equipment
  • Use of one or more of AutoCAD, Solidworks, COMSOL, ANSYS,
  • Holds a PE in one or more related disciplines
