About the job
Technical Salesperson / Project Manager AGES (80-100%)
Technology in mind. Customers in view. Projects under control.
We are looking for doers who recognise opportunities, take responsibility, and develop our international AGES business together with us.
Who we are looking for
For our AGES – Airport Ground Energy Systems business area, we are seeking an entrepreneurial-minded individual who is keen to convincingly combine technical sales and project management.
Together with airports and partners, we develop suitable solutions and get them rolling from the first enquiry to successful commissioning. This requires technical understanding, a good sense for customers, and the joy of reliably keeping an eye on deadlines, costs, and quality.
In short: We are looking for a personality who likes to take responsibility, tackles tasks with energy, and drives our international AGES business forward – because tailwind is welcome not only on the tarmac.
What this role involves
- Winning customers and projects: Acquiring new customers and projects, maintaining existing partnerships, and understanding technical concerns early on. Not with a sales show, but with expertise, reliability, and solutions that convince.
- Developing solutions: Recording technical requirements, developing suitable system concepts, and creating well-founded, market-appropriate offers.
- Bringing projects to completion: Taking responsibility for the entire project process, from enquiry through realisation to acceptance. Costs, deadlines, quality, and risks are kept in view at all times.
- Connecting people and interfaces: Bringing together customers, suppliers, engineering, production, and assembly. Clear communication and reliable coordination ensure that a good idea becomes a functioning system.
- Working internationally: Accompanying commissioning and customer visits in an international environment and competently representing ISTinox at airports and with partners.
- Further developing AGES: Expanding the business area strategically and operationally together with management. Own ideas are expressly welcome.
What you bring
- Education: A technical basic education forms the ideal foundation. This is complemented by further training as a FH engineer, HF technician, refrigeration planner, or a comparable qualification.
- Technical understanding: Understanding systems, media and piping systems, comprehending dimensioning, and recognising technical risks early.
- Experience with customers and projects: Knowledge in project management, technical sales, or a comparable function.
- Entrepreneurial thinking: Recognising opportunities, taking responsibility, and independently advancing topics without waiting for every next step to be prescribed.
- Communication skills: Conveying technical contexts understandably and discussing solutions competently, pragmatically, and reliably with customers.
- Internationality: Business fluent German and English skills as well as willingness for international customer and project assignments. Additional languages are welcome.
What to expect at ISTinox
- We value not only hard facts: it also has to fit on a human level. We get stuck in, enjoy really good work, and want to make a difference together.
- A team on equal footing: People with whom collaboration is enjoyable: direct, uncomplicated, helpful, and with genuine team spirit.
- Performance principle: Initiative, quality, and responsibility will advance you with us – titles may look good on business cards, but what counts is what you make of them.
- Short paths: Short distances, clear decisions, and direct contact with management – good ideas don’t end up on hold with us.
- Comprehensive security: with 100% continued salary payment in case of illness and attractive pension benefits that grow with your years of service!
- Time to recharge: five weeks’ holiday, six from age 50, plus free drinks from coffee to after-work beer.
- Real team spirit: Whether after-work drinks, barbecues, Christmas dinners, or anniversary trips: We like to celebrate successes together – and good team spirit simply belongs with us.

If you are looking for a job that remains as unexciting as possible, we are probably not your destination. If you love technology, want responsibility, and want to step on the gas with us, we want to get to know you.
A stiff standard cover letter is not necessary. Rather, write to us about what drives you, what you are professionally proud of, and why you fit ISTinox.
