LinkedIn & E-Mail Marketing Manager für B2B Watertech Content

Interius is a specialized strategy and marketing agency for international companies from the water and wastewater industry.

Our clients develop technologies for water treatment, wastewater treatment, reuse, membranes, sensorics, PFAS removal, chemicals, and industrial infrastructure.

This is not lifestyle marketing, no beauty brand content, and no fast social media hype. It's about technically demanding B2B communication for companies that solve real problems in the water industry.

We are looking for someone who has not just "done" LinkedIn and E-Mail Marketing, but really understands it. Someone who can develop a clear content idea from a technical topic, formulate it neatly, and then implement it.

You will work for Interius itself and primarily for our international clients.

Aufgaben

You develop content ideas for LinkedIn, newsletters, and E-Mail campaigns for technical B2B companies from the water industry.

You write LinkedIn posts, newsletters, E-Mail sequences, and short campaign texts in English and German.

You translate technical information, customer input, case studies, product benefits, and market trends into understandable, credible, and relevant content.

You plan, structure, and publish content for client accounts and Interius.

You work with ActiveCampaign and set up newsletters, automations, segments, and simple campaigns there.

You analyze which contents function and lead to new ideas from that.

You work closely with graphics, project management, and management together.

You communicate directly with customers as needed, gather information, and implement feedback professionally.

You keep deadlines, even if multiple customer projects run in parallel.

Qualifikation

You have proven experience with LinkedIn content, ideally in the B2B environment.

You understand how LinkedIn works: reach, hooks, formats, timing, comments, company pages, personal profiles, and the differences between superficial content and relevant content.

You can develop a useful content idea from little input.

You write very good English.

You have experience with E-Mail Marketing and ideally with ActiveCampaign.

You can understand, structure, and explain technical topics clearly.

You are not a beginner and do not need basic training in marketing.

You are self-reliant, organized, and clear in communication.

You can handle customers and understand that a good idea is worthless if it's not implemented neatly.

You are resilient, deadline-oriented, and work structured even when it gets tight.

Benefits

100% remote.

Part-time or full-time possible.

Start immediately possible.

We speak German internally, mainly English with customers.

You will work with international clients from Europe, North America, and other markets.

You get a lot of free space when you deliver.

You work on meaningful topics instead of interchangeable consumer products.

You will be part of a small team with big customers and direct influence on the results.

No corporate policy, no chi-chi, no endless internal coordination.

Please only apply if you really bring experience, work samples, and the claim to deliver good work.

We are looking for someone who masters LinkedIn and E-Mail Marketing professionally, can grasp technical content, and takes responsibility.

Remote means working independently at Interius, not being on the road and hoping it will somehow work out.
