Materials Engineer

**Job Purpose**:
To analyze the physico-chemical and micro/nanoscopic properties of têxtile materials, in order to better understand their interactions with dyes and auxiliaries and to support the development and optimization of dyeing processes.

**Main Responsibilities**:
**Materials Characterization & Analysis**
- Perform micro/nanoscale analyses of têxtile substrates using appropriate meanings.
- Investigate physical and chemical properties: surface morphology and charge, porosity, chemical composition, fiber structure, and functional group reactivity.
- Compare native and post-treated states to assess impact of dyeing conditions or pre/post-treatments.

**Dye-Material Interaction Studies**:

- Conduct lab-scale experiments to evaluate dye-substrate interactions (adsorption, diffusion, fixation).
- Help correlate molecular-scale observations with dyeing behavior (fastness, uptake, uniformity).
- Participate to process adaptations based on material behavior (e.g., surface modification, auxiliary selection, pH optimization).

**Data Interpretation & Reporting**:

- Analyze and synthesize technical results to extract actionable insights for dyeing process optimization.
- Write clear, structured internal reports, and contribute to documentation for scientific, industrial, or regulatory purposes.
- Present findings to the team and contribute to decision-making in project steering.

**Cross-Functional Collaboration**:

- Work closely with the dyeing lab, R&D and process teams.

**Safety & Laboratory Best Practices**:

- Wear appropriate personal protective equipment (PPE) and maintain a safe, clean, organized lab environment.
- Ensure proper operation and calibration of instruments.

**Required Skills and Technical Knowledge**:

- Strong foundation in materials science.
- Practical experience in physico-chemical and microstructural characterization techniques.
- Good understanding of fiber interactions and molecular-scale surface phenomena.
- Familiarity with materials used in têxtile (synthetics, protein, artificial fibers ).
- Skills in data processing, statistical analysis, and scientific reporting.
- Comfortable working in a multidisciplinary team with iterative R&D cycles.

**Education and Experience**:

- Master's degree (or higher) in Materials Science, Polymers, Physical Chemistry, or related field
- Prior experience in applied research (industrial or academic) related to soft materials or surface chemistry is a strong plus
- Knowledge of têxtile dyeing processes is a bonus, but can be learned on the job

**Personal Qualities**:

- **Analytical and investigative**: You enjoy digging into complex materials behavior and drawing conclusions from data.
- **Detail-driven**: You work precisely and value rigorous, reproducible methods.
- **Curious and innovative**: You’re motivated by solving scientific challenges that have real-world impact, and like thinking out of the box.
- **Communicative**: You can translate technical insights into clear, useful information for non-experts.
- **Collaborative**: You enjoy being part of a multidisciplinary environment, sharing your expertise and are flexible in your work to advance team goals.
- **Languages (French/English)**: You are comfortable communicating in both languages in a professional setting.

**Working Conditions**:

- Based in the R&D lab at Biocitech (Romainville, Paris)— remote-friendly environment.
- Use of advanced scientific instrumentation and handling of chemical products (PPE required)
- Collaborative environment with regular interactions across technical and project teams
