Hypothesis creator hiring London engineers for Hegel, open-source property-based testing

David R. MacIver, creator of Hypothesis, is hiring engineers at Antithesis to work on Hegel, an open-source property-based testing library targeting every language. The role is in-person in London five days a week with little flexibility—he admits this is the biggest turn-off, as Antithesis strongly favors in-office work.

He calls it a dream job: cutting-edge testing research in an open-source project with solid resources and a competitive tech-company salary. The team uses Claude Code heavily on Hegel, in a way he's confident yields high-quality output. Sourcing has been a struggle, hence the informal blog pitch.
