Overview
Details
Company
Aerleum is a French deep-tech startup pioneering Reactive Direct Air Capture (Reactive DAC) — a breakthrough technology that integrates carbon capture and conversion into a single reactor. Our mission is to produce cost-competitive, scalable, and sustainable fuels that directly replace fossil-based alternatives in hard-to-decarbonize sectors such as maritime shipping, aviation, and chemicals.
Founded in 2023, Aerleum is backed by top-tier investors such as 360 CP, HTGF, Norrsken, Bpifrance, and Marble and has won several prestigious awards.
So, where are we going now? Scale our technology from lab to commercial deployment and make synthetic fuels a viable alternative at industrial scale.
Main Responsibilities
Mechanical & Hardware Design
- Support the design and development of the reactor’s mechanical systems, including peripheral devices (heat exchangers, piping, structural supports, etc.).
- Participate in brainstorming sessions to propose improvements in reactor efficiency, durability, and performance.
Prototyping & Integration
- Contribute to the assembly and testing of reactor prototypes at various development stages.
- Assist in the integration of peripheral systems (control, safety, automation, etc.) with the reactor core.
Optimization & Scale-Up
- Participate in the development and testing of full-scale prototypes.
- Support efforts to optimize thermal and mechanical aspects of the system for scale-up.
- Help identify potential improvements in system efficiency and cost-effectiveness.
Project Coordination & Documentation
- Assist with equipment selection, supplier communication, and component tracking.
- Help draft technical specifications and contribute to the documentation of procedures and design iterations.
