Your Mission

Job Description

  • Process Development: You will play a vital role in developing the next generation of Direct Air Capture technology. As a specialist in fluid and heat flow dynamics, you will support the Process Development team in modeling, validating, and optimizing Climeworks' carbon capture process.
  • CFD Analysis: You will conduct Computational Fluid Dynamics (CFD) analysis to predict and optimize fluid and heat flows at varying scales — from small-scale modeling of our filter structures to large-scale atmospheric dispersion modeling, which informs plant architecture and enhances CO2 removal capacity.
  • Collaboration with Mechanical Design: Working closely with mechanical design colleagues across departments, you will contribute to designing new structures, vessels, and plant architectures while providing vital temperature, velocity, and other boundary conditions to our design engineers.
  • Model Development: You will lead the improvement roadmap for our CFD models, collaborating with external partners to develop new techniques that enhance simulation accuracy and applicability, particularly in complex multiphase and multiphysics flows.
  • Validation & Measurement: You will plan, execute, and evaluate validation measurements, drawing meaningful conclusions from your findings and collaborating with our Testing teams to ensure our models are robust and well-calibrated.
  • Communication & Presentation: You will communicate results, findings, and observations clearly and concisely to peers, presenting them during technical reviews.

Your Story

Requirements

  • Experience & Expertise: You are a proactive and innovative process or mechanical engineer with at least 5 years of experience in Computational Fluid Dynamics.
