Mechanical Engineer – Field Integrations

We are looking for a hands-on Mechanical Engineer to industrialize the field assembly of Rondo's modular thermal battery systems. Working across product design, project delivery, supply chain, and factory operations, you will develop the products, tooling, documentation, and installation processes that bridge the gap between CAD models and successfully built systems in the field, enabling third-party contractors to construct Rondo systems safely, efficiently, and predictably around the world. The ideal candidate thinks like a manufacturing engineer in a construction environment—creating robust, scalable processes that deliver consistent quality, cost, and schedule performance despite variability in labor, equipment, and site conditions. What You’ll Do (responsibilities include but are not limited to): Create and standardize field assembly processes, turning complex construction activities into repeatable, scalable operations that can be executed consistently by third-party contractors. Partner with product engineering to incorporate Design for Installation (DFI) requirements into product architecture, ensuring modules can be assembled safely, repeatedly, and efficiently by third-party contractors in varying site conditions. Participate in design and construction readiness reviews, establishing release criteria and ensuring field integration deliverables are complete before project execution. Help define site assembly approaches, identify assembly datums, tolerance strategies, interface requirements, and module tolerances required to ensure fitment. Partner with product engineering early in development to eliminate unnecessary site work, tooling, lifting operations, and installation complexity. Develop fixturing, packaging, and transport solutions that are integrated into factory-built modules and remain effective through shipping, storage, and installation. Develop packaging and logistics strategies spanning factory release through final installation, including shipping configuration, storage, material flow, and point-of-use delivery. Develop lifting, handling, transport, alignment, positioning, and installation tooling for modular assemblies. Develop methods of locating modules relative to a central datum system while minimizing cumulative tolerance stack-up. Develop joining processes and tooling for interfaces between modules. Develop leveling and alignment strategies that prevent vertical and horizontal tolerance accumulation. Develop inspection plans, acceptance criteria, and recovery methods for out-of-spec conditions. Apply lean manufacturing and lean construction principles to reduce labor hours, crane time, material handling, installation variability, and overall project cost. Develop mistake-proofing (poka-yoke) features in tooling, interfaces, and work processes to minimize dependence on installer judgment. Create scalable installation standards, work instructions, training materials, and quality plans suitable for deployment across multiple global contractors. Create MBOMs for modules including tooling, packaging, and installation consumables. Perform offline assembly, shipping, handling, and installation validation testing. Develop labor models, equipment requirements, installation sequencing, and productivity assumptions used to establish project schedules and cost estimates. Support project execution through on-site training, commissioning support, and field issue resolution. What You’ll Bring: Bachelor’s in Mechanical Engineering, Manufacturing Engineering, or related discipline. 3-8 years of experience developing manufacturing, assembly, construction, or industrial installation processes for large-scale hardware systems. Strong CAD skills (SolidWorks) with the ability to visualize and communicate complex assembly and construction sequences. Strong understanding of geometric tolerancing, datum structures, tolerance stack-up analysis, and field fit-up strategies. Ability to identify and eliminate unnecessary com…
