Antora Energy median: 52 days open

The posting

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

We are seeking a self-driven and passionate Senior or Staff Mechanical Engineer to join our Product Development Team. In this role, you will own the design, analysis, and validation of subsystems that make Antora’s thermal battery possible. Your work will directly accelerate the demonstration and deployment of a first-of-a-kind long-duration energy storage technology.

This is a highly collaborative, hands-on role where you’ll work across disciplines to scope, design, and refine mechanical systems from concept through prototyping, testing, and production. You’ll also help build the processes, standards, and culture that enable our team to deliver at scale

Roles & Responsibilities

  • Own subsystem design: Lead the architecture, analysis, detailed design, and testing of structural, thermal, and fluid components within Antora’s thermal battery.
  • Perform rigorous analysis: Apply calculations, finite element analysis (FEA), and trade studies to guide design decisions.
  • Drive validation & reliability: Lead prototyping, testing, and root cause analysis to ensure robust, reliable hardware.
  • Pursue cost-down: Identify and implement design and manufacturing approaches that reduce cost without sacrificing performance.
  • Collaborate cross-functionally: Define system requirements, lead design reviews, and integrate feedback across teams.
  • Establish best practices: Develop and maintain CAD standards, documentation, and engineering infrastructure.
  • Mentor & lead: Guide junior engineers; serve as technical lead.

Key Qualifications

  • Senior Engineer: Bachelor’s degree in Mechanical Engineering with 6+ years relevant industry experience, OR Master’s with 4+ years, OR PhD
  • Staff Engineer: Bachelor’s degree in Mechanical Engineering with 10+ years relevant industry experience, OR Master’s with 8+ years, OR PhD with 4+ years
  • Examples of relevant industry experience include power generation, aerospace, propulsion, or other industrial hardware products
  • Proven track record of taking complex mechanical systems from concept to deployed hardware.
  • Strong proficiency with CAD (SolidWorks or similar), PDM systems, and creating detailed drawings (GD&T, ASME Y14.5).
  • Deep experience with machined components for low- to mid-volume production; additional experience with sheet metal, castings, or composites is a plus.
  • Proficiency in structural and/or thermal analysis (FEA and hand calculations).
  • Familiarity with systems analysis and risk management tools such as FMEA.
  • Experience developing engineering processes, standards, and best practices.

Additional Qualifications Desired

  • Experience designing components for very high-temperature environments (500–2500°C).
  • Experience with composite and/or brittle materials.
  • FOAK (first-of-a-kind) product development from concept through sustaining.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
