Job description

• Sora is seeking a visionary Principal Mechanical Engineer to spearhead the mechanical design, engineering, and fabrication of our First-of-a-Kind (FOAK) Sustainable Aviation Fuel (SAF)
• In this role, you will lead the physical realization of an integrated facility that combines novel Direct Air Capture (DAC) technology with a cutting-edge carbonate electrolysis system. You will own the electrolyzer mechanical architecture as we transition from our prototype system to a pilot system. You will take the design from concept through physical fabrication and commissioning, turning advanced chemical workflows into robust, operational industrial systems.
• As our Principal Mechanical Engineer, you will bridge the gap between complex electrochemical/chemical processes and robust industrial machinery. This is a role requiring deep technical expertise, a get it done mindset, and the ability to lead external vendors and mentor internal team members

• Process Equipment Knowledge: Experience selecting and integrating industrial balance-of-plant components, including pumps, compressors, heat exchangers, and high-purity piping systems.
• Startup Agility: Prior experience working in fast-paced, venture-backed hardware startups or highly innovative R&D environments.

Key Responsibilities

Mechanical Design and Engineering

• System Architecture: Responsible for the mechanical design, layout, and structural integration of the carbonate electrolysis system.
• Scale-Up Engineering: Translate bench-scale and custom-component designs into a fully functional, containerized, or skid-mounted industrial pilot plant.
• Thermal & Fluid Systems: Design and optimize piping, custom manifolds, fluid delivery networks and thermal management loops.
• Vendor & Fabricator Management: Select, vet, and manage external EPCs, machine shops, and component suppliers to ensure rapid, high-quality fabrication.
• Cross-Functional Leadership: Partner closely with Chemical Engineers, Chemists, Mechanical and Electrical to ensure flawless mechanical-to-process integration.
• Safety & Compliance: Must have a safety mindset Oversee compliance with relevant pressure vessel, piping, and industrial safety codes (e.g., ASME B31.3, ASME Section VIII).
• Hands-on Assembly & Commissioning: Build, test, troubleshoot, and commission the pilot plant alongside the field team.
• Testing & Validation: Formulate test plans, mechanical commissioning procedures, and safety checklists for newly fabricated platforms.
• Analysis: Analyze physical test data to iterate and optimize subsequent hardware designs.
