Your mission

  • Build and scale ModaResa’s core platform while prototyping new products (like ModaCruising).

  • Manage the full product lifecycle: ideation → prioritization → launch.

  • Balance strategic vision with hands-on execution, pushing both code and culture forward.

  • Lead a small, high-performing team (3–4 in Data, Engineering, Product).

  • Anticipate future hires and build the backbone of our tech org.

  • Drive nearly 100% test coverage, continuous improvement, and tech debt management.
