Senior System Engineer (Thermal and airflow)

Read This First: This is a senior system ownership role—not a general or junior position—with deep responsibility for thermal and airflow performance in high‑power EV chargers. If you don't have strong, hands‑on experience in thermal management of complex hardware systems, this role isn't the right fit by design!

At Siemens eMobility Charging, we develop smart, reliable, and future‑focused solutions for electric vehicle charging. From DC fast‑charging systems to intelligent software for fleet management, we aim to set a high and practical standard within the eMobility industry. Our teams focus on delivering robust, sustainable solutions that support the transition to cleaner and more efficient transportation.

Your role

This is a senior system engineering role with direct ownership of thermal and airflow behavior in high‑power EV chargers.

You ensure that the EV charger functions as a robust, integrated system, operating between system architecture and detailed design. The system architecture is defined elsewhere; you ensure it works in reality.

This role combines system integration responsibility with deep expertise in thermal management and airflow design.

Key Responsibilities

System engineering

• Own system‑level behavior during development and product lifecycle
• Translate requirements into integrated technical solutions
• Ensure correct interaction between power electronics, mechanics, cooling and safety concepts
• Lead system integration, technical decision-making and issue resolution

Thermal and airflow ownership

• Define and own cooling concepts, airflow paths, and thermal derating limits
• Perform and review thermal calculations, heat-load assessments and CFD simulations
• Ensure thermal performance under peak load, environmental extremes and long‑term operation

Mechanical integration and validation

• Define thermal‑related mechanical requirements for enclosures, cooling components and environmental protection
• Support system‑level testing, validation and compliance activities
• Lead thermal root cause analysis for field issues

Role boundaries

This role:

• Owns system integration and thermal behavior
• Owns thermal and airflow solutions end to end

This role does not:

• Define overall system architecture
• Own detailed electrical or software design

What You Bring

• Master's degree in Mechanical Engineering or equivalent
• 7+ years experience in system engineering and thermal design of complex hardware
• Experience in regulated, high‑power or industrial systems
• Ability to take clear technical ownership across disciplines
• Experience with EV charging, power electronics or energy systems is strongly preferred.

What We Offer

• A key technical ownership role in high‑power EV charging
• System‑level responsibility with real design impact
• An expert career path without people management
• A collaborative research and development environment in Eindhoven
• Competitive salary and benefits package
