Customer Success Manager

We provide a platform that helps engineering teams find and fix bugs that traditional testing methods miss. Antithesis runs entire systems in a deterministic simulation, breaks them in every way imaginable, and hands engineers a root cause analysis and perfect reproduction, allowing them to debug faster and ship code with more confidence.

The rise of AI-generated code has made this work more urgent than ever. AI Agents can write code faster than any human, but speed doesn't matter if the output is buggy, stuck in review, or issues are slipping through undetected. The verification bottleneck is real, and it's growing. This is exactly the problem Antithesis exists to solve. We've been quietly reinventing how the world thinks about software reliability, and we're just getting started.

We're well-funded, deeply technical, and building a platform that tackles one of the most complex yet important problems in modern software engineering. If that sounds like fun to you, let’s talk.

Antithesis is not a traditional SaaS product, and this is not a traditional Customer Success role.

Our customers are software engineers, engineering managers, architects, and technical leaders. They are adopting a fundamentally different approach to software testing and reliability engineering. Success requires more than implementation. It requires changes to workflows, processes, testing strategies, and engineering habits.

As a Customer Success Manager, you will help customers successfully adopt and operationalize Antithesis within their engineering organizations. You will work closely with customers, Forward Deployed Engineers, Product, and Account Management to ensure customers achieve meaningful outcomes and realize long-term value from the platform.

This role sits at the intersection of technology, customer success, and organizational change. The strongest candidates will be technically credible, customer-focused, and skilled at helping teams adopt new ways of working.

As a Customer Success Manager at Antithesis, you are responsible for customer adoption, value realization, customer health, and long-term success.

You will serve as the primary post-sale relationship owner for your customers, helping them navigate onboarding, operational adoption, stakeholder alignment, workflow integration, and ongoing value realization. You will partner closely with Forward Deployed Engineers who lead technical implementation and consulting engagements, while Account Managers own commercial strategy, renewals, and expansion opportunities.

Your role is to help customers achieve outcomes.

That means understanding what success looks like for each customer, building a plan to achieve it, identifying obstacles, driving accountability, and helping engineering organizations integrate Antithesis into how they build, test, and release software.

You will also play an important role in shaping the future of the product by translating customer experiences, adoption challenges, and feedback into actionable insights for Product and Engineering.
