AtmosZero 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... Backed by 2150.
About the role
The engineering is unforgiving: high pressure ratios, compressor and refrigerant choices with little precedent at this duty, two-phase heat transfer that must stay predictable across a wide operating envelope. We are taking a working product into volume production, and the thermal architecture set in the next two years will govern every unit after it. You would own a real share of that. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Senior Engineer I (5+ years). You own major subsystems end to end — the refrigerant loop, the steam generation side, or the heat exchanger package — from requirements through test and into production
- Senior Engineer II (8+ years). You own the thermal system architecture for a product line, make the cross-subsystem tradeoffs, and set the test strategy that validates them
- Principal Engineer (12+ years). You set thermal technical direction across programs, resolve the hardest open questions in the technology roadmap, and grow the judgment of the engineers around you
- Define operating envelopes, control strategies, and system architectures for next-generation Boiler 2.0 products, using modeling, test data, and engineering judgment in roughly equal measure
- Lead component selection, sizing, and integration across heat exchangers, compressors, valves, pumps, and supporting equipment — including the supplier conversations that make those choices real
- Own the engineering documentation that holds the design together: P&IDs, system specifications, and design requirements
More about this role
Why this role exists
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.
