Morphology
The meaning is directly compositional: 'in' (inside/within) combined with 'tandem' (an arrangement of items/people one behind another) yields the idea of being in that arrangement — i.e. together or coordinated. This follows a regular preposition + noun pattern and similar expressions exist cross-linguistically, so a B1 learner who knows both constituents can infer the meaning.
Etymology
In tandem comes from a two-seat bicycle called a tandem where the riders sit one behind the other, so they travel in a single line. That's why the phrase means 'one behind the other'.
