Somnia
About Somnia
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.
You’ll join a talented team at Somnia, working across the core blockchain along with novel protocols leveraging its capabilities:
Somnia Agents adding the ability for smart contracts to leverage the latest open-source LLMs and interact with the outside world via headless browsers, powered by on-chain deterministic LLM inference and a decentralised network of agent runners
Prophecy an information oracle that can combine parsing of public websites and public data sources into decentralised, auditable attestations about the real world, powering prediction markets, forecasting and new types of financial systems
dreamDEX a high-performance DEX with a fully on-chain CLOB leveragingSomnia's core capabilities, targeting centralised exchange characteristics
Somnia L1 continued work on the high-performance EVM L1, including working on MEV resistance, privacy, automatic gas sponsorship and 'reactivity' where smart contracts can autonomously invoke themselves based on specific timing or event criteria
About the Role:
dreamDEX makes a hard claim: CEX execution without DEX custody. A fully on-chain CLOB with sub-10ms ambitions, zero trading fees, self-custody and transparent rules, competing head-on with Hyperliquid, Lighter and the large centralised exchanges.
We move customer funds on-chain, where a single settlement error - funds to the wrong account, a mispriced liquidation, a bad fill - have critical impact. Spot is live; perpetuals and event contracts are landing next. Every one of them has to clear a serious quality bar before it touches real money.
You'll own end-to-end testing across the entire system and ensure quality is up to the standard level before anything ships. You've done this on real perpetuals trading systems before, and you know exactly what 'wrong' looks like on an order book.
How We Operate
We move at startup speed with exchange-grade standards. We look for people who are proactive by default: you find the solution before being asked, unblock yourself, and get things done fast without ever trading away quality - on a venue holding customer funds, speed and correctness are both non-negotiable. You take full ownership of your area and treat every problem in it as yours to solve.
Key Responsibilities:
Own end-to-end test coverage across the system: order matching, settlement, margin and liquidation, deposits and withdrawals, the API surface and the frontend
Define the test strategy for every new product and feature before it ships: spot, perps and event contracts
Build automated test infrastructure, using AI to multiply your reach: generated test cases, agent-driven exploratory testing and LLM-assisted triage
Drive a edge-case testing: partial fills, reorg and oracle-deviation scenarios, liquidation cascades and the agent-driven attack surface (we run a live red-team scope for DoS and exploitation on testnet)
Communicate effectively and proactively with other parts of the organisation and drive discussions between different projects. Reporting is a massive part of what you do, you are constantly pushing information to those who need it in order to help them make better decisions.
Run regression and load testing against Somnia's throughput and latency profile
Drive defect management, ensuring issues are prioritised appropriately, root causes are understood and regressions cannot recur.
Requirements:
Must Have
7+ years of QA experience on perpetuals trading systems: a perp DEX, or a perps CEX combined with strong Web3 experience
Fluency in the failure modes of matching engines, settlement and margin systems
Automation-first mindset with strong test-engineering skills
AI-native working style: you use AI tooling daily to write, generate and triage tests, and you're comfortable testing systems that agents trade on
Comfort operating hands-on in a fast-moving environment with significant ownership
Nice to Have
Smart-contract testing experience, fuzzing or a security-adjacent background
Experience testing REST / WebSocket trading APIs and bot or agent integrations
Experience taking a new venue or major trading product through its first launches
