Mechanical Simulation FEA Engineer

About Blue. Heart Energy Blue. Heart Energy was founded in 2016 as a deep-tech company that has developed a new sustainable thermoacoustics technology to radically improve the performance of heat pumps, enabling them to evolve from being the best solution in the market to becoming the perfect solution. Our technology is a disruptive approach to generate heat and cold, with potential to revolutionize the whole industry.

With our so called 'Blue Heart' inside, heat pumps turn into affordable, silent and flexible devices, capable of working with wide temperature ranges suitable for both new and existing houses. Importantly, Blue. Heart doesn’t require any refrigerants and doesn’t generate any CO2e emissions.

About the Role

As a Mechanical FEA Engineer , you will be responsible for performing mechanical analysis of the Blue. Heart Energy heat pump. With the first prototype currently in production, your work will focus on optimizing the design for mass production using FEM software (ANSYS, Marc Mentat, Abaqus…). Before this role was established, all mechanical simulations were outsourced.

Today, you act as the internal consultant , working closely with component owners to define criteria, interpret results, set priorities, and align deadlines. Your input is essential to the design process and product evolution. What You’ll Do Perform mechanical simulations using available SW to assess components such as dynamic membranes, pistons, cylinders, and structural parts Analyze materials including steel, aluminum, and plastics for fatigue, creep resistance, and mechanical integrity Support the Engineering Team by actively collaborating on design decisions, sharing insights, and guiding optimizations Engage in ongoing discussions with designers, analysts, and engineers to translate concepts into manufacturable solutions Contribute to a creative and fast-paced development environment focused on innovation and impact What We’re Looking For MSc in Mechanical or Material Engineering Minimum 5 years of relevant work experience Strong experience in FEA and fatigue analysis; thermal analysis is a plus Proficiency with different analysis SW (ANSYS, Marc Mentat, Abaqus) is a strong advantage Knowledge of materials such as metals, elastomers, and plastics Ability to propose and communicate design modifications Fluent in English, both spoken and written Comfortable working in a startup environment; team-oriented and goal-driven What We Offer Salary range between €5.

200 – €6.200 gross per month (depending on experience) Opportunity to participate in the ESOP scheme, directly linked to company value creation and individual performance. 25 vacation days. Hybrid work arrangement supporting autonomy and work–life balance. Training opportunities to support in your personal and professional development with access to extensive training opportunities at your request.

Access to Open. Up, because we prioritize mental well-being. Participation in our pension scheme with employer contribution. Commuting allowance, in line with our travel policy. A strategic role in a purpose-driven scale-up, contributing to a greener world and shaping the future of sustainable thermal technology. Learn more about our mission here .
