About GTCX Sovereign

GTCX partners with corridor authorities to deploy governed verification infrastructure across Africa.

About this role

This role builds reliable verification services, governed evidence flows, and practical operating outcomes across African corridors.


What you might work on

  • Design high-throughput verification services that keep evidence, operator review, and corridor decisions reliably connected.

  • You're strong with concurrency, distributed systems, and service design

  • You prefer simple, maintainable solutions to hard problems

  • You debug well across services, queues, and databases

  • You're low ego, direct, and hold yourself to a high bar

  • You can work on site in San Francisco


Nice to have

Our Core Values

  1. Traders Win, We Win

    If traders aren't getting better outcomes, we haven't earned the right to scale. Every internal decision gets pressure-tested: does this make traders' lives better? If we can't draw the line, we question why we're doing it.

  2. High Standards, High Care

    We hold a high bar for the team because traders are counting on us to get this right. But high standards only work with genuine investment in each other. You can take risks, admit mistakes, and challenge ideas—not despite our standards, but because of them.

  3. Thoughtful Urgency

    We move fast by default, but speed without judgment is recklessness. The discipline is knowing which decisions are reversible vs. not. In trade AI, the companies that win will be fast everywhere they can be and careful everywhere they must be. We build the muscle to do both.

  4. Intensely Measured

    We instrument trader outcomes, operator ROI, system performance, and verification accuracy. But data without action is surveillance. Every metric should have an owner, a threshold, and a response plan. If we're measuring something but never acting on it, we stop measuring it.

Who Builds With Us

  • Low ego: Politics and territory don't interest you. The best ideas win, regardless of who has them.

  • Direct: You say the hard thing, challenge ideas openly, and commit fully once decided.

  • High agency: You thrive on trust rather than instruction. When you see something is broken, you fix it. You don’t file tickets and wait for someone else.

  • Bar of excellence: Verification agents run on one corridor data foundation — field capture becomes packaged evidence, and independently reviewable evidence clears sovereign verification bars.

  • Skeptical: You push back on rules that don’t make sense and question assumptions that haven’t earned their place.
