antithesis

Antithesis builds an autonomous software testing and deterministic simulation platform designed to verify running systems, compress production hardening into minutes, and help engineering teams ship code with confidence. The platform serves engineering teams building mission-critical systems across sectors such as capital markets, databases, event streaming, blockchains, ledgers, and distributed systems. Antithesis applies automated fault injection, intelligent exploration, and a custom hypervisor to stress-test software, reproduce bugs, and provide automated root cause analysis.

The company is actively building its technical and go-to-market functions as reflected in its open roles. Antithesis is hiring for an Applied AI Software Engineer to focus on building AI-native products, agent workflows, and full-stack applications for go-to-market and marketing operations. This open role is located in Vienna, Virginia, United States, and requires four or more years of professional software engineering experience, including the independent shipment of production systems and LLM-powered workflows.
