About The Position

About Antithesis Antithesis is a developer tools company building a fundamentally new approach to software testing. Our platform combines advanced fuzzing and property-based testing with large-scale deterministic simulation to find deep, correctness-critical bugs that traditional approaches miss. We work with customers who care deeply about correctness, reliability, and trust in complex software systems. Antithesis is in the early stages of productizing a powerful underlying technology. While core capabilities exist and are already in use by customers, many workflows, abstractions, and product surfaces are still being shaped. This is an opportunity to help turn deep technical capability into a coherent, usable, and durable product over time. We have recently formed a dedicated Product organization and are intentionally investing in product judgment, clarity, and long-term coherence as we scale. The role: We’re hiring Product Managers to own meaningful parts of Antithesis’s product and help shape how it evolves over time. This role is about making good product decisions under ambiguity. You’ll be responsible for framing problems, defining structure where little exists, making tradeoffs, and owning outcomes within one or more product areas. You’ll work closely with Engineering and Design, but you will not be a delivery manager or a requirements conduit. You should be excited about early-stage product work: defining workflows, clarifying abstractions, and making foundational decisions that will shape the product for years to come. Product Managers at Antithesis are expected to exercise judgment, take ownership, and care deeply about conceptual clarity and customer outcomes.

Requirements

Experience owning product decisions in complex or technical domains
Comfort operating with ambiguity and incomplete information
Experience working on early or evolving products, not just scaled ones
Strong reasoning and communication skills
A bias toward action combined with thoughtful tradeoffs
