Job summary

Hireroo Ltd in Barcelona, Spain, seeks a Senior Thermal Engineer to own the thermal architecture for advanced compute hardware, from die to rack level, including liquid cooling and sled design. This senior IC role collaborates with mechanical, power and hardware teams in a hybrid Barcelona setting.

You will define thermal budgets, validate methods and drive CFD/thermal simulations, ensuring hot spots are controlled while supporting telemetry and power management decisions.

Qualifications

• 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.

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.
