About the job
Technical Director Engineering / Lead Engineer Plant Construction 80–100%
Shape technically instead of managing. Develop solutions that stand the test in practice.
We are looking for doers with deep technical expertise.
People who do not see engineering as an end in itself, but as the basis for safe, economical and cleanly realisable plants.
Who we are looking for
We are seeking an experienced technical professional who works closely with our management, project managers and design team, takes responsibility, justifies decisions technically and actively develops our engineering further. This is not primarily about personnel management, but about technical leadership, technical judgement and the ability to advance others with good solutions. You use your freedom, tackle topics independently and bring projects to a structured and reliable conclusion even when it gets technically challenging.
What this role is about
As Technical Director Engineering / Lead Engineer, you are one of the technical minds at ISTinox. You take technical responsibility for demanding projects and support our project managers wherever in-depth engineering, calculations or process engineering knowledge are required. You work closely with management, project management, design, purchasing and production.
- Capture customer concerns: Record technical customer concerns at first contact, recognise initial ideas and needs and accompany them as a competent contact person in further project clarification.
- Develop concepts: Develop technically sound and economical solution and plant concepts.
- Plants and components: Plan, calculate and dimension plants and components.
- Engineering: Take responsibility for process engineering and mechanical engineering in demanding projects.
- Technical fundamentals: Develop clear technical fundamentals for project management and design and ensure that the solutions also work in manufacturing and assembly.
- Complex customer projects: Accompany complex customer projects from the concept phase to technical implementation.
- Support and sparring: Support our project managers as a technical sparring partner in demanding technical questions.
- Technical review: Review concepts, designs and critical components with a high quality standard.
- Collaboration: Work closely with management, project management, design, purchasing and production.
- Standards and processes: Pragmatically further develop technical standards, methods and processes.
What you bring
- Education and professional experience: Ideally a technical basic education as a designer, plant and apparatus builder, polymechanic or education as a mechanical engineer FH/ETH, ideally with a specialisation in process engineering, as well as several years of experience in process engineering plant construction.
- Technical understanding: Very good understanding of design, calculation and technical specification.
- Customer-specific solutions: Experience with demanding, customer-specific plants and solutions.
- Problem solving: Enjoy analysing technical problems in a structured way and solving them pragmatically.
- Technical support: Ability to support designers and project managers technically.
- Working style: Independent, structured and solution-oriented working style.
- Language skills: Good German and English skills.
What to expect at ISTinox
- We value not only the 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 it.
- Short paths: Short routes, clear decisions and direct contact to management – good ideas don’t end up in a waiting loop 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.
- Genuine 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.
Sound like you?
If you are looking for a job that remains as unexciting as possible, we are probably not your target. If you love technology, want responsibility and want to go full throttle with us, we want to get to know you. A stiff standard cover letter is not necessary. Rather write to us what drives you, what you are professionally proud of and why you fit ISTinox.
