Customer Success Engineer

About Antithesis

We’re on a mission to redefine how modern distributed systems are tested and released. Our platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility. Our platform doesn’t just assure system correctness and reliability, it exists because developers need something better. If you’ve ever experienced the pain of a production outage, had a bad week on-call, or had a release delayed by weeks because of one killer bug – you’ll understand exactly why we’re doing what we do.

If you're passionate about developer-first products, system resilience, and correctness, we’d love to talk.

Our Customer Success Engineers make our customers successful. How? We dig in to understand our customers’ complex software systems and their pressing business needs, then we use our cutting edge platform to help customers thoroughly test their mission-critical applications. We’re sitting with engineers at companies that are building exciting and ambitious systems, and we’re ensuring that they find their bugs before their users do.

CSEs must understand customers’ business needs and technology to provide value throughout the customer lifecycle, from onboarding to delivering necessary customizations to presenting concise and powerful value propositions to customer leadership. Responsibilities also include identifying missing product features, surfacing new requirements, thinking up new application domains and product areas, and figuring out how best to educate people in the tech industry about these new techniques and approaches for testing at a much larger scale.

In this role, no two days are the same- one day you will be onsite with a customer, helping them resolve a high priority bug and then presenting the results to their entire team; the next you are collaborating in the office with your peers on a new testing technique; or expanding your capabilities as you put the latest open-source technology under testing.
