Fermentation Engineer

Syklea is a pioneering French biotechnology company developing breakthrough solutions for CO₂ capture and valorization. Our mission: transform carbon into sustainable, bio‑based resources that have a positive environmental impact.

As part of our international expansion, we are opening a new facility in New Jersey, USA, and are looking for a Fermentation Engineer to join our growing team. The successful candidate will be responsible for the end‑to‑end management and optimization of microbial fermentation processes, from laboratory to pilot scale.

This role offers a unique opportunity to join a deeptech company at the crossroads of biotechnology and environmental innovation.

• Design, execute, and optimize fermentation processes at laboratory, pilot, and pre‑industrial scales.
• Develop and refine experimental protocols to improve productivity, robustness, and yield of target strains.
• Conduct metabolic and analytical monitoring of cultures, including growth kinetics, biomass/product ratios, and process parameters.
• Operate and maintain bioreactors and fermentation systems (setup, sterilization, and operation).
• Analyze experimental data, interpret results, and propose improvements for scale‑up.
• Ensure full compliance with quality, safety, and hygiene standards.
• Collaborate with process and engineering teams in both the U.S. and France to integrate biological results into technological developments.

• Master’s degree in Biotechnology, Microbiology, or Bioprocess Engineering.
• 3–7 years of professional experience in microbial fermentation or bioprocess development (R&D or industrial setting).
• Demonstrated ability to manage independent research or process operations from planning through execution.
• Experience in scale‑up/scale‑down and data‑driven process optimization preferred.
• Previous experience in a deeptech startup or environmental biotech project is a plus.
• Strong command of fermentation techniques and process control.
• Proficiency with data analysis tools (Excel, statistical software, or bioprocess monitoring platforms).
• Excellent documentation practices and organizational skills.
• Ability to work autonomously, with sound judgment and scientific rigor.
• Adaptability and initiative in a fast‑moving, cross‑functional environment.

Compensation:
Competitive salary based on experience + performance bonus

• Fluent English (required) – main working language.
• French is a plus, as regular communication with our R&D team in France will be expected.

• A self‑motivated scientist or engineer with a passion for sustainability and applied biotechnology.
• Analytical and rigorous, yet pragmatic and solution‑oriented.
• Comfortable working both independently and collaboratively across borders.
• Driven by purpose — eager to contribute to carbon reduction through biotechnology.
