Descripción de la vacante

Dioxycle is seeking a highly skilled Process Development Engineer to join during a pivotal phase of transition from R&D to industrial piloting and early commercial deployment in Paris, France.

You will split time roughly 70/30 between process simulation/design and hands-on experimental work, with the experimental share increasing during key testing campaigns. You will work closely with our principal process engineer to translate research into robust, industrial-scale designs.

Formación

• Master’s degree in Chemical Engineering or related field.
• 3+ years of process engineering experience in an industrial setting.
• Strong command of Aspen Plus for process simulation and optimization.
• Hands-on experience with pilot/ skid-scale experiments.
• Fluent in English and able to work in a tight-knit technical team.
• Good project management and milestone-tracking skills.

Responsabilidades

• Simulate, model, and optimize process flowsheets (Aspen Plus) to support design and de-risking decisions.
• Benchmark and screen candidate technologies, engaging with suppliers to identify the right solutions.
• Scope, follow up, and steer external technical and experimental studies by suppliers and partners.
• Contribute hands-on to pilot/skid-scale campaigns during peak testing.
• Collaborate with the principal process engineer to translate research into industrial designs.
• Bring an industrial/operations mindset to test constraints against real plant conditions.

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 Bill‑Gates-founded Breakthrough Energy Ventures, Lowercarbon Capital and Gigascale Capital and have raised $40M to date. We operate from two centers in Paris and California (so whether you are passionate about outdoors or good food/art scenes, we have a location for you to join!)

Your Mission

Dioxycle is seeking a highly skilled and hands‑on Process Development Engineer to join our team at a pivotal phase of transition from R&D to industrial piloting and early commercial deployment.

We are looking for a process engineer with real industrial-scale experience (rather than a pure R&D or academic background) who can bring a critical, hands‑on, plant‑minded perspective to our process design and de‑risk our path to commercial scale. You will work in close partnership with our principal process engineer, splitting your time roughly 70/30 between process simulation/design and hands‑on experimental work, with the experimental share increasing to roughly 50% of your time during key testing campaigns. Your responsibilities will center around:

• Simulate, model, and optimize process flowsheets (notably using Aspen Plus) to support process design and de‑risking decisions

• Benchmark and screen candidate technologies, and engage directly with technology suppliers to identify and validate the right solutions for our process

• Scope, follow up, and steer external technical and experimental studies run by suppliers and engineering partners

• Contribute hands‑on to pilot/skid‑scale experimental campaigns (e.g. purification skids, evaporators), particularly during peak testing periods

• Work in close, day‑to‑day partnership with our principal process engineer lead to translate research‑stage thinking into industrially robust process designs

• Bring an industrial/operations mindset to challenge and stress‑test process choices against real plant constraints

We seek a Process Engineer who is dedicated to advancing our mission and possesses the skills outlined below. Candidates with a minimum of three years of relevant experience are encouraged to apply (experience levels up to 10‑12 years will also be considered for a more senior scope). We are seeking a candidate who is based in, or open to relocating to, Paris, France.

Abilities and expertise we are looking for

• Master’s degree in Chemical Engineering, Process Engineering or a related field
• 3+ years of process engineering experience gained in an industrial setting (large industrial group strongly preferred)
  • Profiles coming from pure academic R&D, technology licensors, or EPC contractors are not the primary fit for this role
  • Profiles with R&D experience embedded within a large industrial group, particularly in a technical support‑to‑operations capacity, are a strong fit
• Strong command of Aspen Plus for process simulation and optimization
• Domain expertise in either of the following is a strong plus:
  • Liquid organic chemicals (alcohols, carboxylic acids) with experience in purification and separation processes, notably distillation columns
  • Syngas handling, treatment including PSA, cryogenic separation, drying.
  • Ore refining/processing (lithium, nickel, bauxite) with experience extracting metal oxides from mined rock
• Hands‑on comfort with experimental and pilot/skid‑scale work
• Strong fluency in English, with the ability to work closely and effectively in a tight‑knit technical binôme
• Good project management skills: planning, coordination, supplier follow‑up, and milestone tracking
• A genuine appetite for moving from a paper‑based idea to real, industrial‑scale execution

Mindset we are looking for

• 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 have to offer

• Unique journey: We are an early‑stage company with a world‑class team and a flat structure.
• Impact: We are building a product that will reshape century‑old industrial processes to build a better, more sustainable and resilient world
• People‑first: We love our people. We are excited to see one another every morning when coming to work. We choose people and they choose us to share a similar excitement.
• Feedback over ego: We are self‑improving whilst helping others grow. We are no‑ego doers and we are all responsible for shaping the company.
• International team: We are an international team made up of over 17 nationalities, and hopefully many more soon!
• Fun : We constantly strive to cultivate a great work atmosphere and organize regular team events.
• Competitive compensation packages
• Generous Employee Stock Ownership plans
• Health Insurance: Medical, dental, and vision coverage.
• Ergonomic work stations & state‑of‑the‑art equipment
