Process Development Engineer (Paris)

About the Company

This is a climate-tech company developing electrochemical technology that converts industrial CO2 emissions into sustainable chemicals, aiming to displace fossil fuels in chemical production. Their team works across chemical, mechanical, and systems engineering. Having completed their industrial-scale prototype, the company is now moving toward first-of-a-kind plant deployment and commercial roll-out.

The company is backed by climate-focused investors and has raised venture funding to date.

The Mission

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

The company is 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 process design and de-risk the path to commercial scale. The role involves working closely with the principal process engineer, splitting time roughly 70/30 between process simulation/design and hands-on experimental work, with the experimental share increasing to roughly 50% during key testing campaigns.

Key responsibilities:

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 solutions
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 the principal process engineer 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

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). The role requires being based in, or open to relocating to, the location above)

Abilities and expertise sought

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 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 one 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 and 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 pairing
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 sought

Strong work ethic and self-driven attitude
Resourceful problem-solver who finds a way with the means available
Committed to a kind, high-performance, and fun on-site work culture
Passion for innovation
Willing to go the extra mile on deliverables
Humble, low-ego, and curious
