Location: Houten, NetherlandsLanguage: English requiredWork authorisation: Right to work in the EU requiredAbout the roleA growing clean-energy technology company in Houten is developing industrial systems designed to replace fossil-fuel-based process heat.The company develops technology combining solar thermal, Power-to-Heat and Thermal Energy Storage, and is looking for an R&D Engineer to help develop and improve these physical products.This is a very hands-on R&D environment. You will not simply be designing components on paper – you will be involved in concept development, calculations, prototyping, testing and commissioning equipment in the field.What you will be doingDevelop and improve components and systems for renewable industrial heatWork through the full product development cycle from concept through prototype and validationCarry out mechanical and thermodynamic calculations and simulationsDesign and develop new components and system improvementsBuild and test prototypes and validate technical solutionsAnalyse system performance and identify opportunities to improve efficiency, reliability and scalabilityWork with suppliers to develop and source new componentsPrepare designs and products for manufacture and deploymentSupport installation, testing and commissioning of prototypes and new technologyWork closely with electrical, engineering, project and commercial teamsTravel internationally for prototype installation, testing and commissioning when requiredWhat we are looking forDegree in Mechanical Engineering, Energy Engineering or a closely related disciplineIdeally 3+ years of relevant engineering/R&D experienceStrong theoretical and practical engineering skillsExperience with product development, prototyping or engineering projectsComfortable moving between calculations/design work and hands-on testingExperience with thermodynamics, heat transfer, mechanical systems or energy technology is highly relevantStrong problem-solving ability and a hands-on mindsetInterest in renewable energy and industrial decarbonisationWillingness to travel internationallyEnglish is mandatoryRight to work in the EU is mandatoryThis role should appeal particularly to engineers with experience in thermal systems, process engineering, mechanical product development, energy systems or industrial R&D who want to work on a physical technology rather than software-only development.The current technical focus includes Thermal Energy Storage, solar fields and Power-to-Heat, with responsibilities spanning product development, thermodynamic/mechanical calculations, prototypes, validation, manufacturability and field testing.Darwin Recruitment is acting as an Employment Agency in relation to this vacancy.Lasma Kehre
