Senior Plant Engineer, Mechanical & Process | Antora Energy | San Jose, CA, USA
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 to work out of our location in San Jose, California. 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
- Define, 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.
- Translate project, product, and system-level requirements into executable process designs for test and commercial thermal energy storage projects.
- Review cross-functional engineering deliverables, including equipment specifications, piping layouts, instrumentation, controls concepts, and mechanical designs, to ensure alignment with process requirements.
- Participate in process safety reviews, including PHAs, HAZOPs, HAZIDs, design reviews, and related risk assessment activities.
- Perform engineering trade studies that balance performance, cost, manufacturability, operability, safety, and schedule.
- Use both quick-turn analytical methods, such as spreadsheets and hand calculations, and more rigorous model-based approaches when appropriate.
- Support the development and selection of industrial mechanical equipment, including pressure vessels, pumps, heat exchangers, air coolers, fans, tanks, piping, valves, and related process systems.
- Collaborate closely with mechanical, electrical, thermal, fluids, controls, operations, manufacturing, and project execution teams.
- Support commissioning, testing, troubleshooting, and continuous improvement of Antora’s thermal energy storage systems.
- Apply 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.
