Process CAD Engineer (Autocad)

About Dioxycle

Dioxycle is pioneering breakthrough carbon utilization technologies that convert industrial emissions into sustainable chemicals with unprecedented energy and cost efficiency. By displacing fossil fuels for the production of key chemicals, Dioxycle has the potential to ultimately reduce over 800 million tons of CO2 per year, representing over 2% of the world’s emissions.

At the core of our process is a novel "carbon electrolyzer", a machine capable of using just electricity and water to convert carbon emissions back into valuable everyday essential chemicals. Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality through this completely novel technological approach. Having completed our industrial‑scale electrolyzer prototype, we are now working with our chemical and downstream offtakers towards First‑of‑a‑kind plant deployment and subsequent commercial roll‑out.

We are supported by world‑class funders including Breakthrough Energy Ventures, Lowercarbon Capital and Gigascale Capital and have raised $40M to date. We operate from two centers in Paris and California.

Your Mission

Dioxycle is seeking a highly skilled and hands‑on Process CAD Engineer to join our team at a pivotal phase of transition from R&D to industrial piloting and early commercial deployment. You will be technically rigorous and execution‑oriented with deep expertise in AutoCAD (P&IDs, Plant 3D, BOM integration) and strong fundamentals in process engineering.

Responsibilities

• Own development, drafting, and continuous improvement of P&IDs using AutoCAD Plant 3D.
• Own development of layout, plot plans and 3D models using AutoCAD Plant 3D.
• Ensure strong integration between P&IDs, 3D models, line lists, equipment lists, and engineering/procurement documentation.
• Size process lines (gas and liquid) and core equipment based on process requirements.
• Perform equipment selection and prepare technical specifications and datasheets.
• Interface with vendors and suppliers.
• Help structure and standardize Dioxycle’s engineering workflow.

Abilities and Expertise

• Master’s degree in Chemical Engineering, Process Engineering or a related field.
• 4+ years of experience in process engineering, plant design, or industrial projects.
• Strong expertise in AutoCAD Plant 3D (P&IDs, layout, plot plan, 3D modeling, isometrics, BOM extraction and integration).
• Experience building and managing intelligent P&ID databases connected to equipment and line lists.
• Solid understanding of process design fundamentals: fluid dynamics, heat transfer, pressure drop calculations, equipment sizing.
• Familiarity with industrial standards (ASME, ISO, pressure equipment directives, etc.) is a big plus.
• Experience working on pilot plants, skid‑based systems, or small‑to‑mid‑scale industrial installations is a big plus.
• Good project management skills (planning, coordination, supplier follow‑up, milestone tracking).

Mindset

• Exemplary work ethic and self‑driven attitude: you get things done fast and to a high standard and you don't drop the ball.
• Street‑smart: you don't take no for an answer and will figure out a way to solve anything with the means available.
• Commitment to the mission and ambition and to creating a kind, high‑performance and fun atmosphere at work (100% on‑site role).
• Passion for innovation and problem‑solving attitude.
• Dedication to investing time and effort for the betterment of the team.
• Going the extra 20% that makes a good deliverable into an outstanding deliverable.
• Humble, low‑ego and curious.

What We Offer

• Unique journey: an early‑stage company with a world‑class team and a flat structure.
• Impact: building a product that will reshape century‑old industrial processes for a better, more sustainable and resilient world.
• People‑first: we love our people. We choose people and they choose us to share a similar excitement.
• Feedback over ego: we are self‑improving while helping others grow.
• International team of over 17 nationalities.
• Fun: regular team events and a positive work atmosphere.
• Competitive compensation packages.
• Generous Employee Stock Ownership plans.
• Health insurance: Medical, dental, and vision coverage.
• Ergonomic workstations and state‑of‑the‑art equipment.

Our Process

• Initial video call with Grace, Director of People.
• Initial interview with Bastien, Director of Engineering.
• Technical deep‑dive interview/case study with Bastien.
• On‑site interview with opportunity to tour our technology and meet the wider team.
• Series of reference calls.

We may use artificial intelligence tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
