Job Description

Antora builds and deploys thermal energy storage to power always-on industrial operations and data centers with low-cost energy. Factory-built in California, Antora’s thermal batteries deliver reliable and cost-effective heat and power for industrial loads of any size. Antora is electrifying global industry while supporting U.S. manufacturing jobs, lowering costs for energy consumers, and enhancing the competitiveness of American industry.

We are growing our company with people who put team and mission first, value connection through laughter and joy, and build with humility and openness. We are committed to continue building a diverse, passionate, and creative team dedicated to a future where every industrial facility, everywhere on earth, is powered by abundant, clean, low-cost energy.

The Role

Antora is seeking a self-driven and passionate Senior or Staff Mechanical Engineer, Fluid Systems to join our Product Development Team. In this role, you will own the design, analysis, and validation of critical 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.

You should be excited to pair strong first-principles engineering with modern tools, including AI-enabled workflows where they meaningfully improve speed, insight, or iteration quality. Just as important, you’ll bring the judgment to validate outputs, challenge assumptions, and keep engineering rigor at the center of every decision.

What You'll Do

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 hand calculations, finite element analysis (FEA), and trade studies to guide design decisions, while thoughtfully leveraging AI and other modern tools to accelerate learning and engineering execution.
Drive validation & reliability: Lead prototyping, testing, failure analysis, and root cause investigation to ensure robust, reliable hardware.
Pursue cost-down: Identify and implement design and manufacturing approaches that reduce cost without sacrificing performance or reliability.
Collaborate cross-functionally: Define system requirements, lead design reviews, and integrate feedback across adjacent engineering and operations teams.
Establish best practices: Develop and maintain CAD standards, documentation, and engineering infrastructure that support high-quality execution and scale.
Mentor & lead: Guide junior engineers and serve as a technical leader within the team.
Shape our processes: Balance fast execution with long-term improvements in team workflows, risk management, and product development culture.

Key Qualifications

Education & Experience: B.S. in Engineering (Electrical, Software, Mechanical, Automation, or related) and/or 5+ years of experience in demanding industrial environments (e.g., Oil & Gas, Chemicals, Power Plants).
Controls Expertise: Proven track record programming "greenfield" and "brownfield" PLC and SCADA software, with specific proficiency in Allen Bradley (Studio 5000) and/or Ignition (Inductive Automation).
Communication Protocols: Familiarity with industrial protocols including Modbus, CAN bus, Ethernet/IP, and Profinet.
Hardware Fluency: Ability to read and interpret electrical schematics and P&IDs, prov
