Design of thermodynamic cycles and sizing of related equipment

NEEXT; Belfort; On-site; EUR 13,000 - 20,000; Full time

Job summary

NEEXT, a young startup in Belfort, seeks an engineering intern to support the design and optimization of its reactive fluids driven thermodynamic cycles. The role focuses on modelling, sizing, and experimental validation planning.

You will work on rules for main cycle components, develop Python-based sizing tools, and contribute to early prototypes for demonstrating industrial feasibility, with English as the working language.

Qualifications

• Knowledge of thermal engineering, fluid mechanics and thermodynamics.
• Interest in programming and Python scripting.
• Proactive, autonomous and capable of proposing action plans.

Responsibilities

• Establish design rules for main cycle components (pumps, valves, pipes, heat exchangers, turbines, compressors).
• Develop tools for sizing and modeling main components (preferably using Python scripts).
• Conduct conceptual studies for NEEXT's customers.
• Contribute to defining prototypes to demonstrate industrial feasibility.

Job description

About NEEXT

NEEXT is a young start-up located in Belfort and supported by FRANCE 2030 that ensures the industrial development of a main innovation based on new patented working fluids known as 'reactive fluids'. These promise to significantly improve the performance of thermodynamic cycles, particularly those related to heat-to-electricity conversion and heat pumps.

Context

NEEXT designs thermodynamic cycles using reactive fluids as working fluids. Those fluids patented by CNRS add a chemical dimension to the thermodynamic principles enabling a significant yield gain but increasing the complexity of the cycle. Since this is a recent innovation, it still requires a modelling effort to design and optimize both cycles and equipment. The upcoming activities are therefore focused on modelling and sizing processes and equipment.

Topics and missions of the internship

• Establish consistent and comprehensive design rules for the main cycle components (pumps, valves, pipes, heat exchangers, turbines, compressors).
• Develop tools for sizing and modeling the main components (ideally using Python scripts).
• Conduct conceptual studies for Neext's customers.
• Contribute to defining prototypes aimed at demonstrating industrial feasibility.

Your profile

• Agility, ability to adapt in a changing environment.
• Curiosity, proactive mindset and ability to make suggestions.
• Communication, ability to address blocking points and seek information within the team.
• Autonomy, capacity to propose action plans to ensure successful completion of assigned tasks.
• Knowledge of thermal engineering, fluid mechanics, and thermodynamics.
• Knowledge of and interest in programming.
• Operational proficiency in English.

Practical information

• Location: Belfort, France
• Start date and duration: starting February/March 2027 for 6 months
• Salary: we have cookies sometime (to be discuss, we pay all our interships)
• Possibility of employment at the end of the internship.
