Staff Thermofluids Engineer

Type One Energy•Knoxville, TN

12d•Hybrid

About The Position

The Staff Thermofluids Engineer will be responsible for the design, analysis, and delivery of thermal fluid systems supporting the Infinity One stellarator and future fusion power plant development efforts. The Staff Engineer is an expert leader of multiple, complex projects and initiatives, often influencing business direction through technical decisions. This role will contribute directly to the development and integration of the plant’s steam generator and associated heat transport systems, applying software-based analysis, simulation, and thermal-hydraulic modeling to guide design decisions across multiple projects. The successful candidate will collaborate closely with internal teams and key engineering partners, including AECOM, to ensure effective integration of thermal-fluid systems within broader plant architectures.

Requirements

Bachelor’s degree in Mechanical Engineering, Chemical Engineering, or related field.
Demonstrated experience in analytical thermodynamics, heat transfer, and fluid dynamics calculations.
Demonstrated experience with designing and operating water-cooling systems and associated components.
Experience performing analytical and numerical analysis of thermal/fluid systems using simulation and property tools such as REFPROP, GASPAK, HePAK, ASPEN HYSYS, or other relevant software.
Demonstrated ability to use modelling and simulation results to provide technical guidance across multiple projects and inform system-level engineering decisions.
Experience drafting PFD and P&ID.
Strong problem-solving skills and ability to work cross-functionally in a collaborative engineering environment.
Excellent written and verbal communication skills.

Nice To Haves

Master’s or Ph.D. in a relevant engineering discipline.
Experience with steam generators is desired.
Experience working on fusion machines is a plus.
Experience in system-level modeling, controls integration, and data analysis.
Experience with HAZAN, HAZOPS, system commissioning and operation
Ability to own and execute on multiple projects.
Experience in a fast-paced R&D or startup environment.

Responsibilities

Perform analytical thermodynamic, fluid dynamics, and heat transfer calculations on the machine's core and support systems to support design and performance evaluation.
Design and/or specify key components of the system such as piping, pumps, valves, heat exchangers.
Develop PFDs / P&IDs and other relevant design documentation for this system.
Contribute to steam generator design, sizing, integration, and performance evaluation in collaboration with AECOM and other engineering partners.
Set technical strategy for projects and initiatives.
Use software tools and simulation methods to provide technical guidance, trade studies, and design support across multiple concurrent thermofluids projects.
