Job Summary
Own end-to-end test coverage across the system, including order matching, settlement, margin, liquidation, deposits, withdrawals, the API surface, and the frontend. Define the test strategy for every new product and feature before it ships, covering spot, perpetuals, and event contracts. Build automated test infrastructure using AI for generated test cases, agent-driven exploratory testing, and LLM-assisted triage. Drive edge-case testing for partial fills, reorgs, oracle deviations, liquidation cascades, and the agent-driven attack surface via live red-team scope. Run regression and load testing against Somnia's throughput and latency profile while managing defects to ensure root causes are understood and regressions do not recur. This role requires 7+ years of QA experience on perpetuals trading systems with an automation-first mindset and AI-native working style.
