Mechanical Reliability Engineer Test Infrastructure & ThermalFluid SystemsRole snapshot
Help keep sophisticated mechanical test assets running at peak performance. In this sustaining-focused role, you’ll support, maintain, and continuously improve complex test infrastructure used to validate advanced energy systems. Your work ensures high-fidelity test stands remain operational, reliable, and truly representative of realworld conditions.
You’ll engage with test environments that span thermal management, fluid handling, air handling, pumps, manifolds, and related subsystems used to evaluate cells, modules, and full system assemblies.
A week in the life
From early triage on a misbehaving pump skid to refining a DAQ sensor integration with Controls, your days mix handson troubleshooting with systematic rootcause analysis, documentation, and crossfunctional collaboration. You’ll partner with Test Technicians to maximize uptime, align with Design Engineering to translate requirements into robust hardware, and constantly look for ways to increase stability and reliabilityalways with a sharp focus on safety.
Core responsibilities
- Troubleshoot and repair mechanical issues across complex test rigs and stands.
- Lead rootcause analyses on systems involving thermal management, fluid circuits, air handling/HVAC, and related equipment.
- Translate test requirements into rugged mechanical hardware and infrastructure with Design and Test Engineering.
- Work shouldertoshoulder with Test Technicians to sustain high uptime and resolve issues quickly.
- Collaborate with Electrical and Controls teams to integrate sensors, actuators, and data acquisition hardware.
- Track system performance and drive improvements to reliability, stability, and uptime.
- Ensure test assets accurately emulate intended operating conditions for validation activities.
- Create and maintain CAD models, BOMs, work instructions, and other technical documentation.
- Document troubleshooting steps, root causes, and corrective actions.
- Identify and retire technical debt within legacy and inservice test infrastructure.
- Advance continuous improvement across equipment and mechanical systems.
- Champion safety when working with highpower, pressurized, thermal, and chemical systems.
