Substitute Teacher - on call

About us and our community

At the International School Rheintal (ISR), we pride ourselves on combining first-class educational standards with a personal community. As a fully accredited International Baccalaureate (IB) World School, we teach around 220 students from Kindergarten to 12th grade on our award-winning, ecologically designed campus in Buchs SG and offer a globally recognized curriculum that empowers learners to succeed anywhere in the world.

We believe that our strengths lie in our size: high mutual trust, a deep connection between teachers and students, and an environment where every individual is valued and perceived. At ISR, our team is intrinsically motivated, highly professional, and always ready to stand up for one another. As a close campus community, we work directly at the heart of the action. This also means that we value flexible and solution-oriented colleagues who do not see tasks outside the formal job description as an obligation, but as a valuable opportunity to actively contribute to an outstanding international learning environment and help shape the functioning of a vibrant school community.

About the role and daily work

Substitutions play a crucial role at our school. When regular routines are interrupted, you step in to ensure that our students experience continuity, care, and high-quality instruction without interruption. This is an on-call position. As a rule, we will contact you approximately 24 hours in advance when a teaching unit needs to be covered. We do not expect 100% availability, but a reliable basic availability makes cooperation beneficial for both sides.

The ideal person understands and accepts this unpredictability. Entering a classroom at short notice means adapting spontaneously, embracing a dynamic day, and acting flexibly with a calm, positive presence. We are a supportive, open team that ensures you receive lesson plans, teaching materials, and administrative support as soon as you arrive on campus. In return, you will experience the joy of getting to know our students of different age groups, building real relationships with colleagues, and enjoying a flexible work schedule.

What it means to do great work with us

We measure success by the impression you make when you walk through our door:

• You enter the classroom with enthusiasm, quickly build a good rapport with the students, and shape the day's learning experience positively and safely.
• You exchange ideas with the teachers before and after class -- for example, through feedback on how the day went, what was worked on, and what observations enable a seamless reintegration for the main teacher.
• Students and team members are genuinely happy to see you in the hallway because you bring a calm, supportive, and hands-on energy to the team.

What you bring

• Genuine joy in working with our students as well as an open, curious attitude towards different areas of our school.
• The willingness to ask questions in case of uncertainty, to adapt when plans change at short notice, and to focus on solutions during unexpected challenges.
• Excellent English skills (our language of instruction) as well as clear, empathetic communication with children and adults.
• Ideally, you possess a recognized Bachelor's degree, a teaching diploma, or a qualified pedagogical education in the child sector. We also consider equivalent practical experience in leading, teaching, or supervising groups of children.
• Willingness to undergo security checks (criminal record extract) for working with children.
• Work permit & Place of work: You already possess a valid work permit for Switzerland that allows employment on an hourly basis. ISR cannot apply for new work permits for this position.

If you are looking for a flexible, meaningful activity with young people -- and for the chance to become a valued, familiar face in our warmhearted international school community -- this is the perfect entry.
