• Customer service - providing technical advice, resolving application‑related issues, and ensuring adherence to customer service standards.

What You Will Need

• Higher technical education: chemical engineering, chemical technology, environmental engineering, environmental protection, chemistry, or a related field.
• Preferred experience in water treatment or an industrial environment (2–3 years).
• Willingness to engage in long‑term cooperation (approx. 12‑month onboarding process).
• Category B driving licence and availability Monday‑Friday.
• Readiness for occasional training and service travel within Poland and abroad.
• Computer literacy and proficiency in MS Office.
• English language skills.
• High personal culture, responsibility, communication skills, reliability, and willingness to learn and develop.

• Work‑Life Balance: Flexible working arrangements with hybrid model of work (approx. 60% from the office and 40% from home)
• Matrix Organization: Thrive in our matrix organisation, working across Europe with various teams and cultural backgrounds.
• Collaborative Environment: Strong teamwork and diverse interactions.
• Development Opportunities: Personalised plans with rapid progression
• Versatile Career Paths: Professional growth supported by active committee for different career levels.
