Improbable

At Improbable, we build and scale ambitious AI and Web3 ventures shaping the next generation of the internet. The Somnia Foundation, backed by Improbable, specialises in building and operating high-performance decentralised technology. Its EVM L1, launched in 2025, has been benchmarked as the fastest on the planet: at over 1 million ERC-20 transactions per second. At Somnia you'll be working alongside a talented team working across the core blockchain along with novel protocols leveraging its capabilities. 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

Protecting the perfect run of existing partners and features is job one. * Analytical Leadership: Being the definitive source of truth on Swap.

Sales or BD experience is highly valued. * Operational excellence: Evidence of running something with rigour - managing operational risk, reducing errors, and optimising conversion or engagement. * Influence in a matrixed organisation: Proven ability to align resources and drive complex cross-functional initiatives without direct authority. * Consumer fintech / service-revenue background: Experience in a high-volume transactional or service-revenue business is highly desirable. Fintech or equivalent service experience is a must. * Digital assets: Crypto experience is a strong plus. * AI: Strong appetite for what AI can bring to analysis and operations is a must. * Total English fluency: Role is based in Paris; French is not a prerequisite.
