AtmosZero is building next-generation industrial steam infrastructure. The company's flagship product, Boiler 2.0, is a modular industrial steam heat pump designed to help manufacturers reduce operational risk, improve flexibility, and modernize steam generation. Rather than forcing facilities to choose between reliability and sustainability, AtmosZero enables a practical path toward future-ready steam systems that integrate with existing operations and scale with customer needs.
As Mechanical Engineer, System Integration (Engineer III), you will own the mechanical integration and packaging of the complete 1 MW system. This role reports to the VP of Engineering and is central to turning individual components into a repeatable, manufacturable product.
Key responsibilities include:
- Own mechanical integration and packaging of the complete 1 MW system, including equipment layouts, skids, process piping, structures, supports, enclosures, lifting, shipping, installation, and service access.
- Integrate heat exchangers, compressors, pumps, valves, electrical hardware, controls hardware, and supporting equipment into controlled system layouts.
- Develop and release 3D assemblies, routing, drawings, BOMs, interface definitions, and supplier-ready design packages.
- Support suppliers and fabricators through design review, fabrication, receiving, assembly, integration, and test.
- Resolve packaging and build issues with technicians, manufacturing, supply chain, process, controls, and test teams; drive ECOs and drawing updates to closure.
- Apply DFMA, modularization, packaging optimization, component standardization, and configurable-design methods.
- Translate Unit 1 build and test learning into repeatable designs for Unit 2 and later systems.
- Support lifting, transport, installation, commissioning, and field-service planning for packaged equipment.
Success in your first year means: understanding the full package architecture and owning a defined system-integration work package within 90 days; releasing layouts and drawings and resolving build issues by six months; and delivering a validated packaging or modularization improvement incorporated into Unit 2 or later production design by twelve months.
REQUIREMENTS:
- Bachelor's degree in mechanical engineering or related discipline, with experience appropriate to Engineer III level.
- Strong fundamentals in equipment layout, piping, structures, supports, tolerances, thermal growth, load paths, lifting, and serviceability.
- Experience integrating multidisciplinary industrial hardware from layout through detailed design, release, fabrication, assembly, and test.
- Experience developing large 3D assemblies and production-quality drawings in SolidWorks or comparable CAD/PDM environment.
- Ability to create and review specifications, BOMs, drawings, interface definitions, calculations, ECOs, and design-review records.
- Ability to work directly with fabricators, suppliers, technicians, and cross-functional engineering teams in a fast-moving hardware environment.
PLUS (nice-to-have):
- Experience with process skids, packaged industrial equipment, HVAC or refrigeration equipment, industrial heat pumps, pressure equipment, process piping, or comparable integrated hardware.
- Deep SolidWorks experience with large assemblies, configurations, weldments, routing, drawings, BOMs, and PDM-controlled release.
- Working knowledge of ASME B31 piping requirements, structural design, welding, fabrication, GD&T, or piping-stress analysis.
- Experience with DFMA, product modularization, configurable designs, value engineering, new-product introduction, or field installation.
