Jobbannons

APR Technologies is a Swedish deep tech company developing high-performance liquid cooling solutions for data centers, space, defense, telecom, and battery applications. Our core technology Rheion™, co-developed with NASA, ESA, and Airbus, controls and redirects cooling liquid flow at chip scale, removing thermal barriers to technological progress while saving energy and enabling higher compute density.

We are now looking for a Fluid & Coolant Specialist to join our R&D team in Enköping, Sweden.

The role

In this role you will design and test fluid handling systems and components, focusing on thermal performance, flow, pressure, and materials compatibility.

Key responsibilities:

• Evaluate and select fluids/coolants based on thermal, hydraulic, electrical, chemical, environmental, and reliability requirements.

• Continuously monitor the market for existing and emerging coolant technologies.

• Characterize and assess fluid properties including viscosity, density, thermal conductivity, specific heat capacity, dielectric strength, vapor pressure, and electrical conductivity.

• Define qualification methodologies and perform verification testing of new fluids.

• Define and execute material compatibility testing with metals, polymers, elastomers, adhesives, coatings, and electronic materials.

• Investigate coolant ageing, contamination, corrosion mechanisms, and degradation effects throughout product lifetime.

• Define and perform electrohydrodynamic pumping performance testing for new fluids.

• Support mechanical and electrical engineering teams in material selection and fluid-related design decisions.

• Maintain and continuously develop a database of fluid properties, compatibility data, and test results.

• Assess environmental, health, safety, and regulatory aspects of coolant candidates, including sustainability and recyclability considerations.

• Participate in design reviews and contribute to engineering decisions related to cooling technologies, fluid selection, and system reliability.

• Collaborate across engineering disciplines to ensure integrated product performance.

Required qualifications:

• Degree in Chemical Engineering, Thermal Engineering, Chemistry, Materials Engineering, or equivalent.

• Knowledge of coolant chemistry, electrochemistry, thermophysical fluid properties, and material compatibility.

• Understanding of liquid cooling systems, and heat transfer relevant parameters.

• Experience in experimental testing and data analysis.

• Strong analytical, communication, and documentation skills.

• Fluent in English.

Meriting qualifications:

• Experience with dielectric fluids, liquid cooling, or molecular pumping technologies.

• Experience in coolant qualifications, reliability testing, or material compatibility assessments.

• Hands-on experience with pumps, flow systems, and instrumentation.
