Science Lab English Teacher

Puesto: Full time Science Lab English Teacher
Location: San Luis Potosí

Who We Are  Harkness Institute is not your typical high school. We're a bicultural, bilingual preparatory school where education happens around discussion tables, not lecture halls. Founded on the belief that Mexico's education can and should be exceptional, we've built something different—a place where motivated students and passionate educators come together to explore ideas, challenge assumptions, and prepare the next generation of thoughtful leaders.
This isn't a place where the teacher commands from the front of the room—here, teachers facilitate, guide, and learn alongside their students.
We believe in education as a force for social good, in academic rigor paired with genuine support, and in the power of diverse perspectives to deepen understanding. Who We Are Looking for  You're not looking for just any teaching job. You believe education can transform society. You see teaching not as delivering information, but as igniting curiosity, fostering critical thinking, and developing young minds who will tackle tomorrow's challenges.

You're adaptable—ready to embrace a teaching method that might be radically different from what you've experienced, one where you're a guide and facilitator rather than the sage on the stage.
Whether it's the elegance of chemical reactions, the complexity of living systems, or the interconnectedness of environmental science, your enthusiasm is genuine and contagious. You want students to fall in love with science the way you have.
You're humble enough to recognize that great teaching requires continuous learning.
The Opportunity  We're seeking a  full-time Science Teacher  to join our San Luis Potosí campus. This position offers the rare opportunity to teach highly motivated, intellectually curious students in an environment that genuinely supports innovative teaching.
You'll teach science courses in English to students who are preparing for world-class universities. Depending on your expertise, you may teach chemistry, biology, environmental science, or a combination—we're looking for depth and breadth in the natural sciences. You'll have the autonomy to design engaging curricula, develop hands-on laboratory experiences, and create field activities that bring scientific concepts to life.
Most importantly, you'll help shape young people who see science not just as a subject to master, but as a way of thinking about and improving the world.
