Improbable

Improbable is a Venture Builder. We are working with leaders to create businesses in AI transformation, the metaverse and web3. We both create businesses from scratch and invest in existing businesses. Our central services teams work with ventures to help them achieve success; including early stage prototyping and initial product development where this role sits. At Improbable, you are surrounded by people who want to improve everything and everyone around them, and who compel you to improve yourself. We’re motivated by the fulfilment of solving hard problems to achieve something profound and transformative.   Your Mission As a Senior Full Stack Engineer at Improbable, you will work with Ventures to help them get to market faster. You will work with their leadership team, to design, prototype and launch initial versions of their product. This is a hands-on, strategic role where you will collaborate with executives, working all the way from identifying customer problems. About the Role We're looking for a Full-Stack Engineer to build across the breadth of what Somnia ships, from consumer-facing products to developer technologies to internal platform and tooling. One month that's a polished end-user app, the next it's an SDK, a CLI, or the internal systems the rest of the team builds on. This is a role for someone who cares as much about the product as the code. You'll own the full lifecycle, from rapid prototyping to deployment. You use AI tools as a multiplier and like shipping end-to-end. What you’ll be doing * Design and build production-grade products end-to-end—back-end through UI—across consumer apps, developer-facing technologies and internal platform tooling. * Build the high-performance back-ends and services these products depend on. * Create developer technologies—SDKs, APIs, CLIs, libraries and starter kits—that make the platform easy to build on. * Build internal tooling and platform infrastructure that raises the velocity of the whole team. * Work self-directed: watch the ecosystem and the team's needs, spot gaps and propose and build what moves things forward. * Work with DevRel, Marketing and BD so what you build lands with users and developers and fits go-to-market. What we’re looking for * Strong TypeScript across the full stack—this is the core of the role and our app stack. Some Golang where it fits. * Build high-quality, production-ready frontends. * Strong back-end engineering—APIs, services and the data layer behind them. * Genuine interest in crypto and on-chain products. * Strong ownership and self-direction—you generate ideas, not just execute them. * Able to turn the dial: prototype fast and loose to prove a feature out, then shift into steady-state mode to harden what's worth keeping—tests, edge cases, reliability.   Improbable Candidate Privacy Policy
