Build what gets fielded
We are a small team building communications that soldiers will carry. The work is careful, the problems are real, and the bar for "done" is a user trial with a signals regiment.

Where we are hiring
Cryptography & protocol verification
Threshold identity, hybrid key agreement and formal models in Tamarin or ProVerif. You can explain a construction's limits as clearly as its guarantees.
Embedded & radio systems
Bearer integration, scheduling across CNR, LTE, satcom and mesh, and making software work on issued ruggedised hardware.
Field engineering
Taking builds to trials, working alongside signals units, and turning what breaks at 0300 into the next release.
What it is like here
- Claims are tested, not asserted. If a property matters, there is a test that fails when it stops being true.
- Open problems are written down and published, not hidden from customers or from each other.
- Small codebase, deliberately: small enough to be read, audited and owned.
