Job Description Our partner is looking for a Senior Thermal Engineer to own the thermal architecture for advanced compute hardware, from die and package level analysis through liquid cooling, sled design and rack level heat rejection. This is a senior individual contributor role with strong technical ownership. You will define thermal budgets, cooling requirements and validation methods, working closely with mechanical, power and hardware teams. Location: Barcelona, Spain, Hybrid Level: Senior Responsibilities * Own thermal design from silicon to rack level * Define thermal budgets for high power compute hardware * Model die hotspots, package spreading and board level thermal behaviour * Run CFD and conjugate heat transfer simulations * Perform transient analysis using realistic workload power profiles * Design cold plates, manifolds and liquid cooling loops * Define flow rate, pressure drop and coolant requirements * Specify TIM stack, bond line and thermal interface requirements * Define sled and rack thermal architecture * Set coolant distribution,



redundancy and failure response requirements * Own thermal validation on real hardware * Correlate simulation results with sensor and test measurements * Work with mechanical, power and cooling partners * Support thermal telemetry, throttling and power management decisions Requirements * 8+ years of electronics thermal engineering experience * Background in high power computing, data centres or similar electronics * Thermal ownership of processors, GPUs, ASICs or FPGAs * Strong package level thermal analysis * Strong CFD and thermal simulation experience * Icepak, Flotherm, Star CCM+ or equivalent * Liquid cooling and cold plate design * Flow and pressure budget experience * TIM selection and bond line knowledge * Thermal interface reliability understanding * Practical thermal validation experience * Strong simulation to measurement correlation skills Optional / Desired * 2.5D, interposer or chiplet thermal design * Tw
