Turbomachinery Engineer

Atmos Zero is building the next generation of industrial steam infrastructure. Our 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 over time. Rather than forcing facilities to choose between reliability and sustainability, Atmos Zero enables a practical path toward future‑ready steam systems that integrate with existing operations and scale with customer needs.

Industrial steam runs manufacturing - breweries, dairies, pharmaceuticals, specialty chemicals - and almost all of it still comes from a boiler design that predates the jet engine. Much of the U.S. fleet is decades past its prime, facing volatile fuel costs, tightening limits on new combustion, and no cheap way to add capacity.

Boiler 2.0 is a modular heat pump that makes steam at up to 185°C from electricity and air alone. Because it moves heat rather than creating it, it returns roughly 2 units of steam energy per unit of electricity, against well under one for combustion. It drops into the old boiler's footprint and scales by adding modules - no stack, no fuel line, no combustion permit.

Units are in production now in Loveland, Colorado.

The compressor is one of the most important technical and cost levers in the system. We need to move from first‑generation hardware toward production‑intent designs that are lower cost, manufacturable, reliable, and supported by a scalable supplier base. That work spans the full rotating assembly: aerodynamic and mechanical design, motors, bearings, seals, cast components, instrumentation, controls interfaces, supplier execution, and validation.

You would own a real share of that work.

• Engineer III. You independently execute significant turbo machinery design and validation work with limited supervision. You own defined projects or subsystems, exercise sound engineering judgment, coordinate technical interfaces, and consistently deliver meaningful outcomes from analysis through hardware test.
• Senior Engineer I. You lead complex turbo machinery initiatives through ambiguity, own major compressor subsystems or development work streams end to end, mentor teammates, and influence technical decisions beyond your immediate area of responsibility.
• Senior Engineer II. You are a recognized turbo machinery expert who leads highly complex, cross‑functional efforts spanning rotating machinery, motors, suppliers, controls, manufacturing, and system integration. You set technical direction and frequently drive execution without direct authority.

• Work in close partnership with team to develop production‑intent compressor hardware for high‑temperature industrial heat‑pump applications.
• Own key technical work streams across the high‑speed rotating assembly, including impellers, shafts, bearings, seals, housings, motors, interfaces, and supporting instrumentation.
• Translate system‑level requirements into compressor operating maps, mechanical requirements, interface specifications, and validation criteria.
• Lead technical efforts to improve performance, reliability, manufacturability, and cost as the compressor moves toward production.

• Lead compressor cost‑down work involving cast components, part consolidation, alternate manufacturing processes, production‑intent instrumentation, motors, seals, and supplier alternatives.
• Develop and evaluate design concepts that reduce cost and lead time while preserving performance, reliability, safety, and serviceability.
