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
