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.
