Full Job Description
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. Nexus is backed by leading investors, including Pantera, Lightspeed, Dragonfly, Faction, Blockchain Builders Fund, Alliance, and SVA, and works with more than 100 partners across the global finance and blockchain stack. Location: Remote (Argentina) Type: Contract THE ROLE We are looking for a Technical Lead to own the technical architecture across Nexus’s product surface and ensure the code shipped by our engineering pods is coherent, performant, and built to last. You’ll set the bar for how we design systems, write code, and review each other’s work — and you’ll do it with your hands on the keyboard, not just on a whiteboard. You’ll partner closely with engineering management to grow pod maturity, raise the level of technical decision-making across the team, and turn architectural intent into shipped product. 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. WHAT YOU’LL DO - Own the architecture. Define and evolve the technical architecture spanning our Rust services, Go infrastructure, and Next.js/TypeScript surfaces on GCP — and make sure what gets built actually matches it. - Stay hands-on. Write production code in the highest-leverage parts of the stack: critical services, shared libraries, complex inte
