Job summary

Lazarus Energy LLC is hiring a Senior Mechanical Designer to own the mechanical design of sCO₂ power blocks. You will turn thermodynamic and aerodynamic intent into manufacturable hardware, from concept to test and production scale-up, working closely with the founding team.

You’ll design casings, housings, and packaging that holds the machine together, touching nearly every component and driving designs toward robust, producible hardware for a fast-moving startup.

Qualifications

• Bachelor’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 validation
• Sound judgement for how designs interact with structural / thermal / sealing considerations
• Proficiency 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 manufacturability
• Excellent communication skills and a willingness to learn / teach

Responsibilities

• Own 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 practice
• Drive designs to assembled hardware while working with vendors
• Own interfaces and tolerances across the machine to ensure parts integrate cleanly
• Drive DFMA to ensure a solution that is not only fit for initial concept, but long-term production
• Support structural and thermal verification of your designs by partnering with the broader team
• Build, assemble, and test the very hardware that you design
