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 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.
