We believe that the modern world should not be limited by energy. Lazarus is a team with over 50 years of turbomachinery analysis, design, and testing experience. We are building the next generation of power conversion technologies that will solve today’s power demands and tomorrow’s renewable energy future. This is a rare chance to help define a new era of hardware energy products by leading core technology development from concept to test and production.Lazarus is post-stealth and pre-series A. We are moving incredibly fast with a talented team in place, hardware in the door, and active testing underway. We are currently building a MW-class system to fire with natural gas and then integrate with nuclear heat before the end of 2027.Role OverviewThis role owns the mechanical design of our sCO₂ power blocks. You will turn thermodynamic and aerodynamic intent into real, manufacturable, and released hardware. Working directly with the founding team, you’ll design the casings, housings, and mechanical packaging that holds our entire machine together. This is a role that takes clean-sheet design through testing, validation, and production scale up. You’ll touch nearly every component of the machine and will own hardware that directly contributes to the success of the company.ResponsibilitiesOwn detailed mechanical design of the machine and its systems, including the turbomachinery test section, pressure boundary hardware, system-level skid, and piping.Take designs from concept through released drawings with sound GD&T and drawing practiceDrive designs to assembled hardware while working with vendorsOwn interfaces and tolerances across the machine to ensure parts integrate cleanlyDrive DFMA to ensure a solution that is not only fit for initial concept, but long-term productionSupport structural and thermal verification of your designs by partnering with the broader teamBuild, assemble, and test the very hardware that you designRequired QualificationsBachelor’s degree or higher in mechanical or aerospace engineering or similar.Strong mechanical design experience in taking complex hardware from concept through released drawings, testing, and validationSound judgement for how designs interact with structural / thermal / sealing considerationsProficiency in CAD (NX, SolidWorks, CREO, Onshape, or similar) and GD&T per ASME Y14.5.Working knowledge of machining, fabrication, and assembly, and how design choices drive manufacturabilityExcellent communication skills and a willingness to learn / teachPreferred ExperiencesStructural and thermal analysis (FEA, bolted-joint analysis, thermal growth, etc.) of mechanical hardware.Experience with creep and creep fatigue assessment of high temperature alloysExperience with elastic-plastic stress analysisHigh-pressure / high-temperature systems and their mechanical design considerationsPackaging and integration of complex systems onto skids or frames — fitting machinery, piping, and balance-of-plant into a tight, buildable, serviceable envelope.Rotating machinery / turbomachinery hardware designEarly stage or start-up experience.Compensation & BenefitsUS salary range: $140,000 - $200,000Meaningful equity ownershipCompany wide medical, dental, and vision insuranceFully stocked kitchen with snacks, coffee, and lunchThink this is your kind of work?We move fast and we build real things.
