M3XI Get CallMe

Jobs at M3XI

Help us build M3XI.

We’re a small group building CallMe and M3XI Spatial — and aiming at robotics beyond that. We’d love more curious hands. Read the honest bit first, then pick a role.

The honest bit — read before applying

  • We are not funded. M3XI LTD is a registered company in England (no. 17425819), but it is early and small.
  • These are unpaid, volunteer co-builder roles for now — there is no salary yet. If and when revenue arrives, the people who built it with us are first in line.
  • What we can offer today: real shipped products for your portfolio, honest credit for everything you make, a small kind team, and a genuine say in what M3XI becomes.
  • Everything is remote and flexible around your studies or job.

If that excites you rather than puts you off — you’re exactly who we’re looking for.
