?Spain | ? Full-time | Permanent contract Innovamat is
an educational organization focused on mathematics learning. Our
mission is to improve the way the subject is taught, by offering
resources, training and research to the educational community.
Since we were founded in Barcelona in 2017, we have partnered with
more than 27,000 teachers in over 2,800 schools across nine
countries, reaching more than 600,000 students. Within Innovamat,
Mathboard AI is the technology that reads what students write by
hand. When a student solves a problem on a digital board, we
receive the pen strokes themselves — not a photograph, not typed
text. Our models have to work out which strokes belong together and
what each group means, so the student can be understood and helped
in the moment. We are looking for the person who takes those models
further. It is a multiple-instance detection problem on handwritten
input, solved directly on the pen strokes rather than on a rendered
image — a formulation with no off-the-shelf solution to copy and no
public benchmark that stands in for the real thing.



The work is
genuine research engineering: understand where the model falls
short, form a hypothesis about why, build it, and find out honestly
whether it worked. The problem you would be working on A student
fills a page. On it there might be four separate calculations, two
arrows linking one result to the next, a small diagram, a
crossed-out attempt, and a few marks that belong to nothing at all.
The model has to find every one of those objects, say what kind
each is, and say exactly which pen strokes make it up — all at
once, with no fixed number of objects and no guarantee that any two
pages look alike. So it is multiple-instance detection, but the
primitives are strokes rather than pixels. One object is made of a
variable number of strokes; strokes cross and interleave; two
different objects routinely occupy the same region of the page, so
the question is never where an object roughly is but
