Full-Stack Engineer

About Somnia:

SOMNIA is the Agentic Chain – a hyper-performance L1 operating at an order of magnitude faster than existing networks. We empower builders and traders to create real-time, autonomous, and fully decentralized products, powered by agents, that were previously impossible and cannot be built anywhere else. It’s where the future of Web3 protocols will be built, so we’re facilitating a new wave of on-chain applications from DEX to Prediction Protocols and much, much more.

Somnia is being developed by Somnia Foundation backed by Improbable, a British tech Unicorn +++ that has been at the forefront of building virtual worlds for over a decade. Somnia received initial funding from MSquared, which raised $150 million from a16z crypto, SoftBank, Mirana Ventures, CMT Digital, and SIG.

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.

Key Responsibilities:

• 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.

Must Have: Full-Stack Foundation

• 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.

Nice to Have

• Web3 / on-chain experience—smart contracts (Solidity/EVM), wallets, or building dApps.

• Experience building developer technologies—SDKs, APIs, CLIs, or libraries—and the docs and starter kits around them.

• Strong design skills for polished product UIs.

• A good grasp of the competitive landscape—and what makes web3 products good.
