Senior Plant Engineer, Mechanical & Process

Join to apply for the Senior Plant Engineer, Mechanical & Process role at Antora Energy

Antora builds and deploys thermal batteries to power always‑on industrial operations with low‑cost energy. Factory‑built in the United States, Antora’s modular thermal batteries deliver reliable heat and power, enabling industrial facilities of any size to decarbonize predictably and profitably. 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.

Position Summary

We are seeking a self‑driven, passionate Mechanical/Process Engineer to help deliver zero‑carbon industrial heat and power through our novel solid‑state thermal battery. You’ll join a close‑knit engineering team that values impact, humility, and collaboration, and that takes pride in building lasting relationships while tackling hard problems.

In this role, you will play a central part in optimizing Antora’s balance of plant (BOP) systems for both cost and performance. You will develop, own, and continuously refine cost models that integrate data from a wide range of technical and commercial sources. These models will serve as a core, iterative tool to guide the design and evolution of cost‑optimized, high‑performance plant processes and mechanical and electrical architectures.

You will also scope, define, and design BOP systems and equipment for Antora’s commercial thermal energy storage projects. As a key technical contributor within a fast‑growing, cross‑functional organization, your work will directly support the testing, deployment, and scaling of an innovative long‑duration energy storage technology.

Roles & Responsibilities

• Create and own models for equipment, system and plant costs; continuously update models as data is gathered from our constructed projects
• Perform engineering trade‑off case studies that balance performance, cost, and schedule to drive architectural alignment via quick (spreadsheet) and thorough (model‑based) approaches
• Work hand‑in‑hand with other engineering teams (SW/controls, battery engineering, project execution, etc.) at Antora to develop the simplest, lowest‑cost, highest performing BOP system
• Define and own system process requirements and specifications, including heat & mass balance (HMB), Process Flow Diagrams (PFD), and Process & Instrumentation Diagrams (P&)
• Review cross‑functional team designs (equipment specs, piping design, etc.) to ensure they meet the process requirements
• Participate in PHAs, HAZOP, and/or HAZID workshops

Key Qualifications

• Bachelor’s or equivalent in an engineering field (e.g. chemical, mechanical, process, industrial, etc.) and 8+ years’ experience in industrial applications engineering (oil & gas, chemicals, power plants, etc.)
• Experience designing or specifying industrial mechanical equipment such as:
  Pressure Vessels, Pumps, Heat Exchangers, Air Coolers, Fans, Tanks, Piping, Valves
• Working knowledge of industrial mechanical design codes. ASME Section I and VIII, Div. 1, ASME B31.1 and B31.3, API 650, API 610, TEMA, ASTM
• Working knowledge of electrical power distribution systems
• Critical thinking and problem solving skills, ability to think about problems from a first‑principles perspective
• Experience working independently, as well as work in a team‑orientated and fast‑paced startup‑like environments
• Proven ability to lead and operate comfortably across many engineering disciplines (e.g. mechanical, electrical, thermal, fluids, optical, controls)

Additional Qualifications Desired

• Deep engineering experience and intuition, ideally with background in:
  High‑temperature thermal systems, Energy and power conversion, First principle engineering analyses
• Use of one or more of AutoCAD, Solidworks,…
