Antithesis is a developer tools company building a fundamentally new approach to software testing. Our platform uses advanced fuzzing and property-based testing techniques, combined with large-scale deterministic simulation, to uncover deep, correctness‑critical bugs that traditional testing approaches miss—across a wide range of real‑world software systems.

We are early in building a dedicated Product organization around this technology and are focused on creating a scalable, decision‑owning Product function as we ramp go‑to‑market.

We’re hiring a Director of Product Management to lead our Product Management function and act as the Head of Product’s primary partner on product content
.

This role exists to scale product leadership. You will manage Product Managers directly, help shape and refine product direction, and ensure consistently strong product judgment across the organization—without centralizing all decisions in a single person.

You’ll be deeply involved in product vision and principles, while operating within a shared frame ultimately owned by the Head of Product. This is a senior leadership role with real authority, autonomy, and growth potential.

• Lead and develop Product Managers

  • Directly manage PMs and own performance, coaching, and career development
  • Set and maintain a clear bar for high‑quality PM work
  • Ensure PMs operate as true owners of their work, with increasing independence and judgment

• Partner on product vision and strategy

  • Act as the Head of Product’s closest thought partner on product content and major tradeoffs
  • Contribute meaningfully to shaping, refining, and pressure‑testing product vision and strategy
  • Translate high‑level direction into clear guidance for Product Managers

• Apply product principles and ensure decision quality

  • Partner with the Head of Product on developing and evolving product principles
  • Ensure principles are applied consistently in day‑to‑day product decisions
  • Mediate tradeoffs and elevate when new or foundational judgment is required

• Support clear ownership and effective execution

  • Help PMs establish clear ownership and direction for their product areas
  • Ensure product direction translates into clear priorities and effective execution across PM work Adapt ownership and structure as product strategy and customer needs evolve

• Hire and onboard Product Managers

  • Play a leading role in hiring PMs
  • Help define PM role profiles and hiring criteria
  • Ensure new PMs are onboarded into Antithesis’s product philosophy and expectations

• Partner cross-functionally

  • Work closely with Product Operations to ensure process and tooling support good product judgment
  • Partner with Product Design to maintain coherence between product intent and user experience
  • Serve as a first escalation point for cross‑cutting or ambiguous product decisions

We’re looking for a senior product leader who combines strong product judgment with people leadership.

You likely have:

• Significant experience as a Product Manager on complex, technical products
• Experience managing and developing Product Managers
• Strong instincts for product tradeoffs, abstraction, and decision‑making
• Comfort operating in ambiguous, fast‑evolving environments
• The ability to partner closely with senior leadership while exercising real autonomy
• A collaborative, low‑ego leadership style with a bias toward clarity and action

Experience with developer tools, infrastructure products, or highly technical platforms is strongly preferred.

This role is designed to grow over time. While there is no automatic progression, it offers a clear path toward broader product leadership, including potential evolution into a Head of Product role depending on company needs and fit.

• You’ll help build a Product organization largely from first principles
• You’ll have real influence on a technically novel and ambitious product
• You’ll work closely with a Head of Product who values deep thinking and strong judgment
• You’ll shape how product decisions get made as the company scales
