Process / Mechanical Engineer - Energy Efficiency (Parasitic Load)

About Kapture

Kapture specializes in retrofitting carbon capture technology onto existing diesel generators without requiring engine modifications. The installation takes less than an hour and causes zero operational downtime. Their system captures up to 90% of CO₂ emissions, converting it into 99% pure calcium carbonate, a sustainable alternative to carbon-intensive materials in concrete. Kapture is leading immediate decarbonization efforts in heavy industry without waiting for full electrification.

Role Overview

This position seeks an engineer focused on minimizing power consumption across the company's carbon capture system components, including compressors, pumps, blowers, and the gas-liquid contacting stage, all while maintaining capture effectiveness. The work involves hands-on engineering applied directly to physical retrofit units rather than theoretical models. The engineer will collaborate closely with the R&D team to instrument the system, identify and isolate energy losses, and redesign components to optimize performance.

Key Responsibilities

• Conduct audits of power usage within the capture unit's mechanical and electrical subsystems.
• Optimize selection and control of compressors, blowers, and pumps based on actual operating conditions.
• Enhance the efficiency of gas-liquid contact to reduce parasitic energy draw without compromising CO₂ capture rates.
• Analyze and validate improvements by utilizing data from field trials at operational sites.
• Work with manufacturing and process teams to implement design modifications into producible hardware.

Candidate Profile

• Relevant background in process, mechanical, or chemical engineering, preferably with practical experience in compressed gas systems, aeration/DAF, bioreactor gas transfer, or industrial pumping and blower technologies.
• Proven experience in achieving tangible reductions in energy consumption within physical systems rather than through just simulations or models.
• Comfortable working on compact, retrofit-scale units compared to large, fixed industrial installations.
• Capable of working quickly and autonomously within a startup environment.

Why Join Kapture?

• Directly influence a technology already deployed in operational settings, beyond theoretical concepts.
• Engage at the crossroads of climate technology, materials science, and mechanical engineering.
• Work with a company supported by prominent industry groups VINCI and Acciona, with expanding global trials.
• Be part of a fast-paced, technically rigorous, founder-led team.
