Building a mining network that runs on ordinary phones
We are a small, early-stage team. That means broad ownership, short feedback loops, and work that ships to real users quickly. It also means the ambiguity and pace that come with building something before it is finished — worth knowing before you apply.
Our stack is Flutter for mobile, FastAPI and PostgreSQL on the backend, and React on the web.
We have no formally advertised openings right now. We do still read speculative applications, and we keep good ones on file — if you are strong in mobile, backend or security engineering, send us a note.
Email careers@unctech.coEmail careers@unctech.co with a short note about what you have built and anything we can look at — a repository, a shipped app, a write-up. We prefer evidence of work over a formal CV, though send one if you have it.
It helps to be specific about what you actually did on the work you show us. On a small team the difference between having used something and having built it matters, and that is easier to explain up front than to establish later.
UNC is a mobile-first network where people take part through a daily check-in on an ordinary phone, rather than through mining hardware. The project is pre-mainnet, so a good deal of the work is building toward a launch rather than maintaining something already running at scale.
Two constraints shape most of what we build. The first is that the network is meant to represent real, verified people, which puts identity verification and anti-abuse work near the centre of the product rather than at its edges. The second is that we are deliberate about not overstating what UNC is — including in the product copy itself — and engineers here are expected to push back when something we are shipping would give users the wrong impression.
We never ask candidates for payment, cryptocurrency, or wallet credentials at any stage. If you receive such a request claiming to be from UNC, it is not from us.
Fake recruiters targeting crypto companies are common. Genuine contact from us comes from an address ending in @unctech.co, and we will never ask you to buy equipment, pay a processing or training fee, or hand over a recovery passphrase as part of an application. If something claiming to be a UNC hiring process asks for any of those, it is fraudulent, and we would rather you report it to security@unctech.co than quietly walk away from it.
The same applies to interviews. We do not conduct hiring entirely over text-based chat, we do not make offers to candidates we have never spoken with, and we will never ask you to receive or forward payments as part of onboarding — a well-known pattern that ends with the candidate implicated in moving stolen funds. If a process claiming to be ours feels structured to avoid a real conversation, that is worth treating as the signal it usually is.
If you are ever unsure whether an approach genuinely came from us, the safest check costs nothing: contact us directly through an address on this site rather than replying to the message you received, and ask. We would far rather answer that question a hundred times than have one person lose money to somebody trading on our name.
