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 building thermal energy storage systems that deliver zero-carbon industrial heat and power at scale. We are seeking a self-driven, hands-on Process Engineer to help scope, define, and design balance-of-plant systems for Antora’s thermal energy storage projects across test, pilot, and commercial deployments.
As a key member of our engineering team, you will own process engineering deliverables for industrial-scale systems, including heat and mass balances, process flow diagrams, piping and instrumentation diagrams, equipment requirements, and cross-functional design reviews. Your work will directly support the testing, scale-up, and commercial deployment of Antora’s novel solid-state thermal battery technology.
We are a tight-knit team that cares deeply about our mission, our technology, and one another. We work with humility, openness, technical rigor, and a bias toward action. This role is ideal for someone who enjoys solving complex first-of-a-kind engineering problems, collaborating across disciplines, and building practical systems that operate safely and reliably in the real world.
ROLES & RESPONSIBILITIES
- 01Define, develop, and own process engineering requirements and specifications for balance-of-plant systems, including heat and mass balances, Process Flow Diagrams, and Process & Instrumentation Diagrams.
- 02Translate project, product, and system-level requirements into executable process designs for test and commercial thermal energy storage projects.
- 03Review cross-functional engineering deliverables, including equipment specifications, piping layouts, instrumentation, controls concepts, and mechanical designs, to ensure alignment with process requirements.
- 04Participate in process safety reviews, including PHAs, HAZOPs, HAZIDs, design reviews, and related risk assessment activities.
- 05Perform engineering trade studies that balance performance, cost, manufacturability, operability, safety, and schedule.
- 06Use both quick-turn analytical methods, such as spreadsheets and hand calculations, and more rigorous model-based approaches when appropriate.
- 07Support the development and selection of industrial mechanical equipment, including pressure vessels, pumps, heat exchangers, air coolers, fans, tanks, piping, valves, and related process systems.
- 08Collaborate closely with mechanical, electrical, thermal, fluids, controls, operations, manufacturing, and project execution teams.
- 09Support commissioning, testing, troubleshooting, and continuous improvement of Antora’s thermal energy storage systems.
- 10Apply AI tools thoughtfully to improve engineering workflows, including accelerating calculations, organizing design information, supporting documentation, improving review efficiency, generating first-pass analyses, and building repeatable workflows while maintaining strong engineering judgment and technical ownership.
KEY QUALIFICATIONS
- 11Bachelor’s degree or equivalent experience in chemical, mechanical, process, industrial, or a related engineering field.
- 128+ years of experience in industrial process engineering, applications engineering, plant engineering, or related roles in industries such as oil and gas, chemicals, power generation, thermal systems, or heavy industrial equipment.
- 13Experience developing or owning process engineering deliverables such as heat and mass balances, PFDs, P&IDs, equipment specifications, and process design basis documents.
- 14Experience with industrial mechanical equipment, including pressure vessels, pumps, heat exchangers, air coolers, fans, tanks, piping, valves, and instrumentation.
- 15Working knowledge of relevant industrial mechanical design codes and standards, such as ASME Section I, ASME Section VIII Div. 1, ASME B31.1, ASME B31.3, API 650, API 610, TEMA, and ASTM standards.
- 16Strong critical thinking and problem-solving skills, with the ability to approach problems from a first-principles perspective.
- 17Ability to work independently while collaborating effectively in a fast-paced, team-oriented startup environment.
- 18Proven ability to operate across multiple engineering disciplines, including mechanical, electrical, thermal, fluids, controls, and systems engineering.
- 19Strong communication skills and the ability to drive alignment across technical and non-technical stakeholders.
- 20Curiosity and practical enthusiasm for using modern AI tools to improve engineering productivity, documentation quality, analysis workflows, and team knowledge-sharing.
ADDITIONAL QUALIFICATIONS DESIRED "NICE TO HAVE" BUT NOT REQUIRED
- 21Deep engineering experience and intuition in one or more of the following
areas
- 22High-temperature thermal systems
- 23Energy storage systems
- 24Power generation or energy conversion systems
- 25Molten salt systems
- 26Industrial process systems
- 27Heat transfer systems
