Jobbeschreibung

About Antithesis

Antithesis is building a fundamentally new approach to software testing. Our platform uses advanced fuzzing and property-based testing techniques to find deep bugs in customer software and exercise systems in ways that traditional testing cannot.

We are in the early stages of productizing a powerful underlying technology. That means much of our product surface, operating model, and customer workflows are still being defined. This is a high-ambiguity, 01 environment where product judgment matters.

About the Role

We are hiring a Senior Product Manager to help build out the product function at Antithesis.

This is not a purely executional role inside an established system. You will operate in a fast-moving, technical environment where many decisions are first-of-their-kind. You will help define product areas, shape workflows, influence prioritization, determine how we measure success, and partner closely with engineering and design to build durable foundations.

You will mentor other PMs and help raise the bar for product thinking and practice across the team. Formal people management experience is a plus, but not required.

This role is for someone who has built new products or major product surfaces from scratch and is comfortable making high-stakes tradeoffs under uncertainty.

What you’ll do:

• Own one or more major product areas (e.g., onboarding/setup, VPC/on-prem, API, test lifecycle, debugging, fault tolerance testing) end-to-end
• Conduct discovery sessions with customers and understand their needs
• Define clear problem statements and outcomes in ambiguous environments
• Make principled tradeoffs between speed, scope, and technical constraints
• Partner deeply with engineering on complex technical systems
• Influence product strategy and long-term direction
• Define metrics and success criteria
• Help shape product standards and raise the bar for product craft

What we’re looking for:

• Strong Signals:
  • Startup experience
  • Demonstrated 01 product experience (built something new, not just optimized an existing system)
  • Comfort operating in high-ambiguity, fast-changing environments
  • Experience in developer tools, infrastructure, testing, security, or similar technical domains
  • Strong technical fluency (engineering background is a plus)
  • Evidence of product judgment under uncertainty
  • Experience influencing strategy and prioritization
  • Clear, structured written communication
  • Defined and used metrics / KPIs to drive decisions
• Bonus Signals:
  • Early member of a product team that scaled
  • Mentored or hired PMs
  • Helped establish product standards or practices
  • Experience with APIs, developer abstractions, Kubernetes, secure deployments, or distributed systems

Not a Fit If

• Your primary focus has been implementing product frameworks (e.g., Scrum/Agile) rather than building products
• You primarily optimized mature systems rather than creating new ones
• You prefer well-defined environments over ambiguous ones

Why This Role Is Different

• You won’t be plugging into an established PM machine. You’ll help build it.
• This is an opportunity to shape how product works at a deeply technical company while directly influencing the trajectory of a novel platform.
