Location: Munich, Germany

Work mode: hybrid (regular onsite presence is required, 1-2 days in the client office)

Our client is a leading American multinational corporation specializing in wireless telecommunications products and services, renowned for its semiconductor and wireless communication technology.

The project: You’ll join the client’s Data Unit, which runs the data platforms and automation behind a global semiconductor manufacturing operation — production data pipelines, system integration, infrastructure automation, and observability. The team’s job is replacing manual, ad-hoc operations with versioned, traceable automated flows.

You’ll join a small, senior team, own your own use cases end to end from early on, and be onboarded directly by the unit’s manager, including dedicated Apache NiFi and KNIME sessions.

Established systems and new technologies live side by side here. The legacy is being modernized step by step, so you will not only maintain old code but take part in its gradual transformation.

Technology stack:
Apache NiFi, Apache Airflow, KNIME, SQL, API integrations, Python.

What you will get hands-on with:

Production data pipelines and ETL for a real manufacturing landscape
Apache NiFi, Apache Airflow and KNIME: automating data and process use cases
System and application integration via APIs, with SQL-based data validation and transformation
Infrastructure automation and observability
Replacing manual operations with versioned, traceable automated flows
A mix of established systems and new technologies, with legacy modernized step by step

Responsibilities and Tasks:

Automate data and process use cases across the client’s production and manufacturing landscape, designing, building, and maintaining ETL and data integration pipelines
Integrate systems and applications via APIs and perform SQL-based data validation and transformation
Take ownership of assigned use cases end to end, from requirement to running solution, ensuring they’re stable, maintainable, and aligned with business needs
Support users and stakeholders with clear, proactive communication

Our expectations of the ideal candidate:

Bachelor’s or Master’s degree in computer science, engineering, information systems, data science, or a related field
Hands-on experience with ETL or data integration (commercial, working-student, internship, or substantial project work), and with at least one data automation or workflow tool
Working SQL: joins, aggregation, and the habit of verifying that a load actually did what it was supposed to
Practical understanding of APIs and system integration, including authentication, pagination, and error handling

English: Upper-Intermediate (B2+)

Nice‑to‑have:

Process automation or workflow orchestration (Apache NiFi, Apache Airflow, KNIME)
Experience in industrial, manufacturing, or Smart Factory environments
Python or other scripting language
Experience working in cross-functional teams
German language

Soft skills:

Strong communication and user-support skills: you are comfortable being the person a stakeholder comes to directly, and you communicate proactively and clearly
A high sense of responsibility and ownership: you carry a use case to done without being chased
A long-term mindset: you want to grow in this role and domain for several years
An even-tempered, steady style: you value a calm, low-drama working rhythm
Openness to being mentored and trained in a rare, specialized domain, with no need to arrive as an expert

We offer:

Real impact: your work supports a real semiconductor manufacturing operation, and the results are tangible
Direct onboarding by the unit’s manager, including dedicated Apache NiFi and KNIME sessions
Established systems and modern technologies side by side: the legacy is actively modernized, and you can take part in its gradual transformation and, over time, in shaping the architecture
A strong engineering culture: attention to quality and engineering decisions, and careful changes made with their consequences in mind
Autonomy within the project’s requirements: freedom to choose effective ways to solve tasks
A pragmatic approach to AI: it is used and encouraged where you see real benefit, and there is no need to apply it everywhere
A calm working rhythm: no culture of constant pressure or artificial rush, the focus is on quality even when a task takes longer than first expected
An international environment: you work with colleagues from different locations
Social benefits package
Opportunities to speak at company meetups and conferences and to grow professional communities
