Supplier Quality Engineer, Mechanical Systems

Rondo is accelerating industry’s transition to lower-cost, zero-carbon heat and power. 

Our Rondo Heat Batteries turn low-cost renewable electricity into continuous, high-temperature heat and power, enabling industrial facilities to replace fossil-fired boilers without costly process changes. The result is lower-cost, zero-carbon industrial energy delivered safely, reliably, and at 98% efficiency. 

• →5+ years in supplier quality or manufacturing quality in a mechanical or electromechanical hardware environment — castings, fabrications, machined parts, structural weldments, refractory ceramics, or similar.
• →Direct experience with refractory materials — dense fired refractories, insulating castables, or ceramic components — including an understanding of their specific failure modes (thermal shock, spalling, dimensional change under firing), inspection methods, and how their quality requirements differ from standard metallic parts.
• →Hands-on experience with PPAP, FMEA, control plans, and MSA — and the ability to translate that experience into building equivalent processes from the ground up in an environment where they don't yet exist.
• →Strong understanding of mechanical manufacturing processes across both metallic and refractory components: tolerancing, surface finish, heat treatment, welding, forming, firing, sintering — you know how parts are made and where variation comes from.
• →Track record of owning supplier corrective actions through to verified closure, not just issuing 8Ds and waiting.
• →Comfort working in ambiguous, fast-moving environments where the product is still evolving and the quality system has to evolve with it.
• →Experience working across language and cultural barriers with suppliers — Spain-based with willingness to travel to supplier sites across Europe and Asia.
• →Fluent in Spanish and English; additional European languages a plus.
• →Familiarity with ISO 9001 quality management systems; experience in cleantech, energy, or capital equipment a plus but not required.
