Senior Product Manager role focused on building and shaping new product areas in a high-ambiguity, early-stage software testing platform.

Responsibilities

  • 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.

Other

  • 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, 0→1 environment where product judgment matters.
  • 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
  • Strong Signals: Startup experience
  • Demonstrated 0→1 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
  • 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
  • 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.
