Application Engineer (m|f|d) Water Treatment

The Meri Group, part of the Voith Group, is seeking an Application Engineer (m|f|d) Water Treatment to join its Munich team on site. This full-time position focuses on turning customer needs into practical water-treatment concepts and steering proposals from first contact through to contract award. The role is based in Munich and carries Job ID 79062.

The Voith Group is a global technology company with a broad portfolio across energy, paper, raw materials and transport & automotive. Founded in 1867, the group employs around 20,700 people and generates about €4.8 billion in sales, with locations in more than 60 countries. The MERI Group, a wholly owned subsidiary of Voith Paper, brings nearly 40 years of experience, more than 5,500 installations worldwide, and an international team of over 100 experts to deliver environmental technologies for industrial use and, in the future, the Food & Beverage market.

Based in Munich and working onsite, this role is ideal for someone who enjoys shaping technically sound water-treatment solutions, engaging closely with customers, and coordinating across teams. You should be comfortable with travel and fluent in both German and English, ready to travel internationally about 30% of the time.

Day-to-day work in water treatment projects

In this role you’ll meet with customers early in projects to capture their requirements and translate them into clear, actionable specifications for the engineering team. You’ll drive technical and commercial conversations toward a contract award, shaping proposals, definitions of scope, inclusions and exclusions as you negotiate terms along the way. You’ll take ownership of the entire bid process, from developing plant concepts and sizing equipment to performing mass and energy balances, delivering engineering deliverables, and estimating costs.

Using customer and process data, you’ll craft tailored solution concepts and compelling business cases that demonstrate real value. You’ll coordinate cross-functional work across Engineering, Procurement, Sales, Quality and Manufacturing throughout the proposal phase, ensuring alignment and timely responses to clarifications. You’ll prepare decision-ready documentation for management and sales leadership and push the bid forward through negotiations until the customer decides.

You’ll also contribute to refining how engineering designs are developed, improving calculation approaches and proposal tools in close collaboration with Engineering and Sales leadership, so the team can deliver clearer, more persuasive recommendations.

Here’s what the Meri Group needs you to bring to the table:

• A degree in Environmental Engineering, Wastewater Engineering, Process Engineering, Plant Engineering or a closely related technical field.
• Several years of hands-on experience with the planning, design and execution of process plants within a complex industrial setting.
• Solid know-how in plant engineering, including P&ID development, 3D CAD-based concept work, equipment sizing, and performing mass balance and cost calculations.
• A keen analytical mindset, a proactive, detail‑oriented approach and a strong curiosity to learn.
• Excellent presentation and communication skills, with the ability to present the company professionally from initial customer contact through to project award.
• Valid residence and work authorisation for Germany, with unrestricted availability for domestic and international travel.
• Fluency in German and English, both written and spoken.
• A willingness to travel internationally for project activities, around 30% of the time.

At Meri, expect an open and collaborative culture with flat hierarchies and short decision paths, plus teamwork at eye level.
