Process Development Engineer

Dioxycle

Paris, France

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

Abilities and expertise we are looking for

• Master’s degree in Chemical Engineering, Process Engineering or a related field
• 5+ 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
