About the role
About Nexus Nexus is the engine for verifiable finance — a blockchain designed to natively embed the world’s financial system into one compounding system. Built to support every major financial market on a single global exchange, Nexus unifies infrastructure that has historically been fragmented across chains and intermediaries. Headquartered in San Francisco with a growing presence in Buenos Aires, Nexus is proud to be a cross-continental team of engineers, cryptographers, and market builders. We’re investing deeply in the Latin American ecosystem — and always looking for world-class talent to join us.

You’ll partner closely with engineering management to grow pod maturity, raise the level of technical decision-making across

This is a senior individual-contributor role with broad influence — ideal for someone who has been a staff/principal engineer or hands-on tech lead and wants the autonomy and leverage of a small, ambitious team.
