Job Description We are seeking a highly skilled and self-driven Thermal Engineer to contribute to the development and optimization of Corintis’ advanced thermal simulation and cooling technologies. In this role, you will support the design, modeling, and validation of next-generation semiconductor cooling systems, ensuring high-performance thermal management through rigorous multiphysics analysis.

Reporting to the engineering leadership team, you will play a key role in executing thermal design strategies, developing and refining simulation models, and translating customer and system requirements into robust, manufacturable solutions. You will collaborate closely with cross-functional teams to enhance cooling performance, validate designs experimentally, and contribute to the continuous improvement of our thermal engineering methodologies.

Responsibilties:

• Design and develop microfluidic cooling devices based on customer specifications.
• Utilize analytical and numerical modelling to support device design and performance optimization.
• Create mechanical components and assemblies for seamless integration between our product offerings and the customer requirements.
• Produce detailed technical drawings and oversee the manufacturing process maintaining high quality standards.
• Develop and implement specialized test setups to validate the cooling performance and packaging integrity of microfluidic solutions.
• Conduct experimental validation, including testing and data analysis, to characterize and refine prototype performance, ensuring optimal thermal and mechanical integration.
• Gather, analyse, and interpret data from experimental tests, using findings to inform and refine designs.
• Collaborate with customers to tailor solutions to specific HPC and AI platforms.
• Innovate advanced solutions for the mechanical integration of cooling devices into broader systems.
• Contribute to fundamental R&D activities within the Hardware team, fostering a collaborative environment.
• Research emerging technologies and trends in liquid cooling and thermal management. Drive the innovation of energy-efficient and environmentally sustainable cooling solutions.

Requirements:

• M.Sc. in Mechanical Engineering, Microengineering, Materials Science, or a related field; a PhD is a plus.
• Minimum of 5 years relevant industrial experience in liquid cooling for electronic systems, ranging from R&D, product development, testing to industrialization. Ideally in data center applications.
• Strong proficiency in mechanical design, tolerancing, and technical drawing for manufacturing.
• Prior experience in leading a new product from design into volume production.
• Advanced CAD skills (Solidworks preferred).
• Extensive hands-on experience designing thermal management solutions for GPUs, CPUs, or custom AI accelerators.
• Good understanding of advanced packaging (2.5D, 3D integration) and the associated challenges related to thermal management.
• Knowledge of packaging and mechanical integration of microfluidic systems in commercial HPC or AI platforms.
• Familiarity with materials science as it relates to thermal management and system reliability for liquid cooling applications.
• Familiarity with failure mechanisms for liquid cooling in data center applications, and the associated qualifications and tests.
• Direct experience with various manufacturing techniques for both prototyping and final production. Familiarity with 3D manufacturing for rapid prototyping.
• Deep understanding of heat transfer and fluid dynamics, particularly at the microscale.
• Practical experience designing and building cooling loops and test benches for microchannel-based cooling systems.
• Knowledge of industry standards and best practices for liquid cooling in HPC and data centres such as ASHRAE and OCP.
• Coding skills in Python and Arduino are a plus.
• Skilled in creating clear, high-quality technical documentation.

This Is a Great Fit If You:

• Enjoy high ownership and responsibility in a startup environment.
• Like building things from early concepts to real products.
• Are comfortable working with evolving requirements and limited structure.
• Enjoy working closely across teams and making fast, pragmatic decisions.
• Care deeply about product quality and industrialization.

This Won’t Be the Right Role for You If:

• You want a highly structured, slow-moving corporate environment.
• You prefer narrowly defined roles with limited ownership.
• You are uncomfortable with ambiguity or fast iteration cycles.
• You lack experience or interest in liquid cooling technologies.
• You are looking for a fully remote position.
