Mechanical Engineer

RenewCO₂ commercializes electrochemical processes to convert CO₂ emissions into carbon-negative materials. What distinguishes us from other CO₂ reduction approaches is our proprietary catalyst, which enables an energy-efficient and selective pathway to existing valuable commodity chemicals, such as formic acid, ammonia, monoethylene glycol, sustainable aviation fuel, and more. Our products can access existing markets, and our economics are projected to be competitive or advantageous compared to current fossil-based production. We will be in a position to offer differentiated carbon-negative products at competitive prices, thereby having a significant impact on emissions and society. We're seeking highly motivated team leaders and members who want to make a significant positive impact on climate change and are excited to work in a collaborative team setting.

The RenewCO₂ leadership team includes experts in electrochemical catalysis and industrial systems, including Dr. Anders Laursen, Dr. Karin Calvinho, and Dr. Chock Karuppaiah, along with industry leaders such as Arne Ballantine (Founder, Ohmium; former Bloom Energy CEO) and Srushti Parhar (ex-Bloom Energy, software industry veteran). Additional leadership team members bring deep expertise from the chemicals and oil & gas sectors across U.S. and Japanese markets and will actively mentor and support selected candidates.

Role Overview

RenewCO2 is hiring a Mechanical Engineer to design and support the build of mechanical systems for CO₂ electrolyzer equipment (electrochemical stack testers, test stations, and prototype systems). The mechanical engineer will develop system layouts, P&IDs, and SolidWorks designs for cell components, manifolds, piping, and equipment skids, as well as support integration of process equipment into these products. The responsibilities will include performing engineering calculations, defining bills of materials, and preparing manufacturing drawings - and working hands-on with fabrication vendors and technicians through assembly, testing, and commissioning.

Type: Full-time, in person at our office and laboratory in Chikkaballapur (Bengaluru region)

Roles and responsibilities:

• Develop mechanical system concepts, layouts, and equipment designs for CO₂ electrolyzer systems, test stations, and associated process equipment
• Create 3D parts, assemblies, and detailed engineering drawings using SolidWorks
• Interpret and contribute to PFDs and P&IDs, translating process requirements into mechanical system layouts and defining piping, tubing, equipment, and interface requirements
• Perform engineering calculations to support design decisions, component sizing, and evaluation of design options
• Design mechanical components and assemblies, including electrolyzer cell components, plates, manifolds, enclosures, brackets, panels, frames, supports, fixtures, and equipment skids
• Prepare manufacturing drawings with appropriate dimensions, tolerances, materials, and fabrication notes
• Design components for sheet metal work, machining, welding, 3D printing, and other relevant manufacturing processes
• Prepare and maintain Bills of Materials (BOMs), equipment specifications, and engineering documentation
• Support integration of pumps, valves, regulators, heat exchangers, tanks, piping, tubing, and other process equipment into test systems
• Apply Design for Manufacturability (DFM), material selection, and reliability considerations to mechanical designs
• Coordinate with fabrication and machining vendors on manufacturability, component selection, and resolution of design or manufacturing issues
• Participate hands-on in prototype builds, fabrication, equipment assembly, installation, troubleshooting, testing, and commissioning
• Update designs with feedback and lessons learned from fabrication, assembly, and testing
• Work closely with the Electrical, Controls, and Process teams on equipment layout and system integration
• Maintain accurate CAD files, drawing revisions, BOMs, assembly documentation, and work instructions

Required Qualifications

• M.Tech / B.Tech / B.E in Mechanical Engineering or a related branch.
• Strong command of mechanical engineering fundamentals.
• Proficiency in SolidWorks for 3D part modelling, assemblies, and detailed engineering drawings
• Ability to perform engineering design calculations and clearly justify design decisions
• Working knowledge of P&IDs, mechanical system layouts, tolerances, fits, fasteners, material selection, machining, welding, and sheet metal design
• Ability to prepare clear manufacturing drawings, BOMs, and engineering documentation
• Ability to learn quickly, take ownership of assigned activities, and work independently with minimal supervision
• Strong written and verbal communication, with technical documentation that allows colleagues to understand and verify design decisions
• Good problem-solving skills and attention to detail

Why join RenewCO2

• Work on cutting-edge CO₂ electrolysis and climate technologies
• Direct exposure to scale-up and real-world system building, from laboratory testers through pilot systems
• Mentorship from operating leaders with prior experience building electrolyzer and fuel cell companies
• Early-stage involvement that allows your design standards to shape the platform as it scales commercially
• Opportunity to grow rapidly with a deep-tech startup from an early stage
