Of the ten postings, New Vector's is the most strategically revealing because it exposes the awkward economics of trying to commercialize a decentralized protocol. The company employs the core team behind Matrix, the open federated messaging protocol, and ships Riot.im as the reference client. That's the tension: they're a 40-person startup whose stated mission is to make messaging "as open as email" — a mission that, if successful, prevents them from ever owning the network.

Stack signals from what they build: Matrix implies a Python/Twisted homeserver (Synapse), a Go rewrite in progress (Dendrite), a React/TypeScript web client, and native iOS/Android apps. Federation and multi-device end-to-end encryption (Olm/Megolm) are the hard parts — this is one of the few places outside Signal doing production E2EE at scale, and the only one doing it in a federated topology where key distribution can't rely on a central authority.

What the posting reveals about stage: "Team of 40 growing rapidly" plus offices in London and Rennes tells you they've closed enough funding to expand internationally but are still small enough that every hire matters. The Rennes office is a tell — that's where several of the original French Matrix contributors live, so they're anchoring engineering around existing talent clusters rather than chasing London salaries. "REMOTE" being called out alongside two physical offices suggests they're flexible but not remote-native.

Skills and trends highlighted:

• Decentralization is hiring again. Alongside Protocol Labs (also in this thread), New Vector represents a small but persistent cohort betting that federated/decentralized architectures will win on privacy and regulatory grounds.
• E2EE is now table-stakes. Post-Snowden, post-GDPR, "private conversations thanks to multi-device end-to-end encryption" is a lead selling point, not a footnote.
• Open-source-as-business-model continues to be viable but structurally hard — see also OpenCraft in this same thread.

Green flags: Named tech leads, real product traction (Matrix is used by the French government and Mozilla), a mission that's coherent with the product, and honest scope ("growing rapidly" not "unicorn").

Red flags: The posting is truncated but conspicuously vague on which roles they need — a scattershot "we're hiring" post from a 40-person company often signals org-design churn. Also, monetizing a protocol you don't own is genuinely unsolved; Element/EMS hosting is their answer, but it competes with anyone else who spins up a Synapse instance.
